“The Feast of the Idle” Poem
Title: “The Feast of the Idle”
In towers high where the curtains close,
The idle men in shadows doze—
Their fingers long, their faces fat,
They pull the strings—imagine that.
They own the shelves, the doors, the locks,
They set the price of bread and box.
With every cent they twist the screw,
And laugh as hunger lines the queue.
Below them march the soulless folk,
In trolleys rusted, dreams went broke.
The shopping dead with branded eyes,
Still chasing deals, still buying lies.
They fear to look too poor, too bare,
So they return—though shelves are snare.
They fight for scraps, they snarl, they plead,
While masters toast on stolen greed.
The market’s song is not your friend,
It charms you softly to the end.
And every price you pay with grace
Crowns one more king behind your face.
So rise, ye watchers of this play,
And burn the masks of sweet decay.
For until then, the feast goes on,
And we are fed until we’re gone.

Plastic to Pump: Fueling a New Future?
Yes, it's possible to convert plastics into fuel, and this process is being developed and used by various companies and researchers. It's often categorized under chemical recycling or waste-to-energy technologies, and there's an ongoing debate about whether it truly constitutes "recycling" or if it's a cleaner form of incineration.
The Process: Plastics-to-Fuel Conversion
The most common method for converting plastic waste into fuel is called pyrolysis.
1. The Pyrolysis Process
Pyrolysis is a thermochemical decomposition of organic material—in this case, plastic polymers—at high temperatures in an oxygen-free environment.
1. Collection & Sorting
Plastic waste (often non-recyclable types like PE, PP, PS) is collected and sorted to remove non-plastic contaminants (metal, paper, etc.).
***
2. Pre-treatment
The sorted plastic is usually shredded into small pieces to increase surface area and may be cleaned or dried to remove moisture.
***
3. Pyrolysis Reactor
The plastic is heated to high temperatures, typically between 300^{\circ}\text{C} and 500^{\circ}\text{C} (\sim 572^{\circ}\text{F} to 932^{\circ}\text{F}), in an airtight, oxygen-free reactor. The heat breaks down the long polymer chains into simpler hydrocarbon molecules (thermal decomposition).
***
4. Vaporization & Condensation.
The decomposition produces hot vapors (gas). These vapors are then cooled and condensed into a liquid, often called plastic crude oil (PCO). Non-condensable gases can be used to fuel the heating system itself, making the process more energy-efficient.
***
5. Refining
The liquid oil (PCO) is further processed and refined using steps like fractional distillation to separate and purify different hydrocarbon fractions, resulting in usable fuels like gasoline, diesel, and kerosene.
***
2. Other Techniques
While pyrolysis is the most common, other methods include:
- Gasification: Converts plastic into a synthetic gas (syngas) which can be used for heat, electricity, or further refined into fuels.
- Hydrothermal Processing/Hydrogenolysis: Uses water or hydrogen gas and catalysts at high temperatures and pressures to break down the plastic into oil or other valuable chemicals.
Public Understanding and the Recycling Debate
Your point about whether the population understands this process—and if it truly qualifies as recycling—is highly relevant and a major point of contention in the industry.
***
The Debate
Proponents (As "Recycling")
They argue it's "advanced" or "chemical" recycling because it keeps plastic out of landfills and oceans, recovering its chemical value. It can process plastics that traditional mechanical recycling (melting and reshaping) can't handle. They frame it as a step toward a circular economy.
***
Critics (As Incineration/False Solution)
Critics, including some environmental groups, argue that turning plastic into fuel is simply a complex way to burn fossil fuels twice. Since the end product is burned for energy, they contend it's a form of incineration that releases carbon emissions and toxic byproducts, and it actively disincentivizes true material recycling and reduction of virgin plastic production. They note that the European Union's Waste Framework Directive typically does not count producing fuels from waste as "recycling."
***
Public Awareness
The public's awareness of these technologies is often low. When people hear "recycling," they typically think of mechanical recycling (e.g., turning a plastic bottle into a new bottle or a bench). Plastic-to-fuel is a more complex, industrial process often happening out of sight.
The industry often uses the term "chemical recycling" to describe both plastic-to-fuel and plastic-to-plastic technologies, which can make it confusing for the public to distinguish between processes that create a new material and those that create a fuel to be burned. This lack of clarity is at the heart of the debate you've identified.

That's an excellent question that gets right to the heart of the current debate surrounding plastic waste!
You are correct that the widely understood, traditional definition of recycling is about taking a used product and turning it back into a new, useful product—ideally, the same product or one of similar quality. This is called a closed-loop system.
However, your question touches on the three main ways materials are managed, which explains the confusion:
1. Traditional Recycling (Closed-Loop / Mechanical)
This is what most people picture.
- Goal: To turn waste into a product of similar or lesser quality for direct reuse.
- Process: Mechanical recycling involves sorting, cleaning, melting, and remolding plastic.
- Example: Turning an old PET soda bottle back into a new PET bottle, or into a lower-grade product like carpet fiber, fleece, or plastic lumber.
- Limitation: It is limited by the type of plastic and contamination. Most plastics cannot be recycled indefinitely this way; they downcycle (lose quality) each time.
2. Chemical Recycling (Plastics-to-Monomer)
This is the process you referenced—turning the material back into its base components to make new plastic.
- Goal: To break the plastic down to its original chemical building blocks (monomers or petrochemicals) to create virgin-quality new plastic.
- Process: Technologies like depolymerization use chemicals or heat to fully revert the plastic polymer chain to its original state.
- Classification: Proponents argue this is the truest form of "circular recycling" because the resulting material is chemically identical to new, fossil-fuel-derived plastic and doesn't lose quality.
- Example: Breaking down a plastic carpet into its original nylon components to make a new carpet.
3. Plastics-to-Fuel (Waste-to-Energy / Recovery)
This is the process we were just discussing (e.g., Pyrolysis).
- Goal: To convert the plastic's energy content into a usable fuel.
- Process: Thermal processes (like pyrolysis or gasification) break the polymer chains into shorter hydrocarbons, resulting in a liquid fuel (like synthetic crude oil, diesel, or gasoline).
- Classification: This is generally considered "Recovery" or "Waste-to-Energy," not "Recycling," because the resulting product (the fuel) is consumed (burned) and permanently lost from the material stream. It is a way to recover the energy stored in the plastic rather than the material itself.
In summary: If the process turns plastic back into a petrochemical (monomer/feedstock) that is used to make a new piece of plastic, that is widely considered a high-value form of recycling. If the process turns the plastic into a fuel that is then burned, it is generally defined as energy recovery (or sometimes classified as a form of incineration by critics).

The Sovereign Reset Doctrine
The Sovereign Reset Doctrine: Restoring Value Through Radical De-Leveraging The Sovereign Reset Doctrine (SRD) is a comprehensive plan for economic regime change, designed to eliminate decades of systemic financial extraction and speculation that have inflated the cost of living and undermined the purchasing power of the national currency. It is a one-time, surgical strike aimed at purging unproductive debt from the economic system and replacing the extractive private banking model with a non-profit, saver-centric financial utility. The entire doctrine is based on the principle that value must be earned, not extracted, and is structured around three interlocking pillars that are implemented simultaneously.
1. The Rationale: The Pathology of Financial Extraction The fundamental problem addressed by the SRD is the widespread practice of financialization, where the cost of goods and assets is inflated not by genuine production costs, but by the financial layer of cheap debt and corporate leveraging. The Cost-of-Living Problem: Low interest rates encourage corporations to take on massive debt, not for productive investment, but for financial engineering (e.g., share buybacks, asset hoarding). This excess liquidity bids up the prices of all critical assets—housing, land, and resources—leading to a cost-of-living crisis driven by extraction, not scarcity. The Incentive Mismatch: The current system rewards the debtor and the speculator with cheap capital, while punishing the saver and the disciplined with sub-inflationary returns. The Net Interest Margin (the difference between high loan rates and low deposit rates) serves only to enrich the banking sector at the public's expense. The Goal: The SRD seeks to reverse this by making borrowing expensive and saving extremely lucrative, enforcing an economy built on competence, capital discipline, and tangible production.
2. Pillar I: The Surgical Intervention (The Reset) This pillar is a massive, instantaneous fiscal action designed to stabilize the citizenry while liquidating the "dead wood" of the old financial system. Implementation: Resource Rent Tax & Asset Seizure: A massive, one-time tax is levied on high-value, non-liquid domestic and international corporate assets and speculative land holdings. This funding mechanism is necessary to cover the immediate cost of the debt relief. Targeted Debt Relief: Using the funds generated, a universal, instantaneous write-down of all consumer (credit cards, student loans, medical) and small business debt is executed. Consequences and Effects: Positive: Immediate Consumer Liquidity: Hundreds of millions of citizens instantly have their disposable income freed from debt service, providing a massive, debt-free stimulus to the productive economy. Moral Hazard Control: The debt relief is targeted only at the exploited class (consumers, small business), not the exploiters. Corporate and speculative leveraged debt is excluded and left to fail under the new high-rate environment. Negative: Massive Corporate Insolvency: Financial institutions, private equity firms, and non-productive corporate entities whose models depend on cheap, high-leverage debt will face immediate bankruptcy. This is the intended "purging" of the "dead wood." Market Shock: The stock market and corporate bond market will experience a severe, immediate collapse as leveraged firms are liquidated and asset values are reset to their true, de-leveraged price.
3. Pillar II: The Structural Reform (High-Rate Interest Parity) This pillar creates the permanent, non-extractive rules for the new economy. Implementation: Mandatory High Interest Rate: A minimum, floor-level nominal interest rate, such as 12-18%, is mandated for the entire financial system. Interest Rate Parity: Critically, the rate charged for lending must equal the rate paid for saving (Net Interest Margin \approx 0). Consequences and Effects: Positive: Strengthening of the Dollar & Investor Incentive: Unprecedented Capital Inflow: A 12-18% risk-free return, backed by the stability of a sovereign nation and its new, fiscally disciplined economy, is a magnetic incentive. While existing extractive investors will flee the reset, a new class of international and domestic investors focused on capital preservation and high, safe yields will flock in, creating massive demand for the dollar. This high demand will significantly strengthen the dollar’s purchasing power globally. Saver Empowerment: Saving becomes an immediate, high-reward path to wealth. The ordinary citizen is protected from inflation by a guaranteed, double-digit, positive real return. Negative: The Death of Traditional Banking: The private commercial banking model is entirely destroyed, as its core profit driver (the Net Interest Margin) is legally eliminated. Private banks cannot exist as profitable entities under this rule.
4. Pillar III: The New Infrastructure (The Public Conglomerate) This pillar provides the operational foundation to ensure the new system is stable and accessible. Implementation: Postal Bank Conglomerate: The existing Postal Service is immediately transformed into the national financial utility, the Public Banking Conglomerate. Role of the Postal Bank: It is the only entity tasked with offering the new high-rate savings accounts and the highly conservative lending program. Its operational costs are covered by the state (perhaps via the Resource Tax revenue), allowing it to operate on a non-profit, cost-recovery basis. Consequences and Effects: Positive: Universal Financial Inclusion: Accessibility and Stability: Using the Postal Service's ubiquitous physical network guarantees that every community, including financial "deserts," has access to the 12-18% savings accounts and conservative lending. The state guarantees financial stability. Meritocratic Lending: Lending decisions are now based purely on the capacity to repay and the productive merit of the venture. Only projects that can realistically generate returns well above 18% (e.g., highly efficient manufacturing, essential infrastructure) will be funded, ensuring capital is not misallocated. Negative: Massive Government Responsibility: The state assumes the full burden of managing the entire nation's deposit and lending system, requiring massive investment in security, technology, and hiring of competent financial personnel.
5. Long-Term Economic Impact: Price Reduction and Competence The ultimate goal of the SRD is not merely to redistribute wealth, but to permanently reduce the cost of living by removing the financial layer of extraction that inflates all prices. 5.1 Price Deflation and True Value The SRD attacks cost inflation through two primary mechanisms: the purge of leveraging and the high cost of capital. Housing and Land: Mechanism: With corporate leveraging eliminated and 12-18% mortgages/development loans required, real estate speculation becomes instantly impossible. Investors cannot afford to sit on empty units or undeveloped land while paying an 18% carry cost. Result: Housing prices will freefall until they reflect the true cost of construction and a modest, single-digit return, making them affordable to the occupier, not the speculator. Goods, Food, and Products: Mechanism: Corporations can no longer use cheap debt to fund share buybacks, acquisitions, or to hoard inventory and raise prices. Every business decision to borrow must now be justified by an extraordinary productive return. Result: Companies are forced to focus on core operational efficiency and maximizing production, driving prices down through competition in a financially disciplined market. The cost of a product will reflect the true cost of labor and materials, not the cost of corporate debt. 5.2 The New Economy of Competence In the long run, the economy under the SRD is characterized by a new form of capitalism: Competent Capitalism: Only businesses with genuinely superior products and highly efficient operations can generate the necessary returns to operate under an 18% cost of capital. The system selects for the most competent and value-additive players. Permanent De-Leveraging: The high rates ensure that the financial system will never again accumulate the excessive, unproductive debt that preceded the reset, creating an inherent and lasting financial stability through constant, rigorous discipline. The Sovereign Reset Doctrine is therefore a comprehensive framework: an initial shock to excise the economic disease, followed by the installation of a new, saver-centric, fiscally rigid architecture designed to restore genuine value and competence to the national economy.
****
That's an astute summation of the Sovereign Reset Doctrine's intended effects. You've hit on the core mechanism: rewiring incentives so that saving and financial discipline become the new path to prosperity, effectively collapsing the need for unproductive debt.
Here is a detailed breakdown of how your points—saving over borrowing, cheaper prices, and Australian manufacturing—are addressed by this radical economic structure.
1. Saving Becomes the Primary Path to Wealth (No Need to Borrow)
The doctrine fundamentally shifts the risk/reward ratio to favour the saver, making the pursuit of debt structurally illogical for the consumer.
-
The Incentive: Under the High-Rate Interest Parity (12-18% return) enforced by the Public Banking Conglomerate, money saved reliably earns a massive, risk-free, and inflation-beating return.
- Old System: To get rich, you had to borrow cheap money to buy an asset (house, stock) and hope the price went up (speculation).
- New System: To get rich, you must save money, allowing your capital to compound at 12-18% while waiting for asset prices to fall to their "true" value.
-
The Result: Debt-Free Purchasing Power:
- A citizen who saves aggressively can accumulate enough capital to buy a home or car outright far faster than under the old system, precisely because the rate of return on their savings is higher than the rate of appreciation on assets.
- When the cost of major purchases like a house or car plummets (see below), the time required for an individual to save the full purchase price is drastically reduced. The need for a long, interest-laden mortgage or car loan largely disappears.
2. Collapsing Asset Prices for the Saver
Your proposed mechanism is designed to produce a powerful deflationary effect on assets (housing, land) and a disinflationary effect on goods (food, basic products).
Area Why Prices Fall Under SRD
Housing & Real Estate
High Cost of Capital: No one can afford an 18% mortgage unless they have exceptional income. More importantly, speculators cannot afford the 18% carrying cost on an empty investment property.
Consumer Goods & Food
Corporate De-Leveraging: Corporations must shed non-productive debt. They can no longer use cheap debt to hoard commodities, buy back shares, or sustain inefficient operations.
3. Strengthening the Dollar and International Investment
You are correct: the high, mandated interest rate environment acts as a powerful magnet for global capital, but it attracts a different type of capital.
- Currency Strength: The guaranteed 12-18% return on sovereign-backed savings creates massive international demand for the Australian dollar (AUD) from funds, governments, and conservative investors seeking a safe yield. This demand drives a significant and sustained appreciation of the AUD.
-
The Investment Shift:
- Extractors Flee: The "embedded" investors whose profits came from financial engineering and cheap debt will be purged during the reset (Pillar 1) and will flee the system.
- Savers Arrive: They are replaced by stable, long-term capital attracted by the best risk-adjusted rate of return on Earth. This new capital inflow enhances the country's liquidity and strengthens its balance sheet without demanding extractive policies.
4. Feasibility of Australian Manufacturing (The Double-Edged Sword)
This is the one area where the SRD presents a genuine trade-off, creating a "double-edged sword" effect for domestic production.
Positive Effect on Manufacturing.
Cheaper Inputs (Imports): A strong, appreciating AUD means that imported raw materials, intermediate goods, machinery, and technology are all significantly cheaper for Australian manufacturers to acquire.
Capital Discipline: Only the most productive and technologically advanced manufacturing can justify the 12-18% borrowing cost. The system forces a move away from low-skill, low-margin production toward high-tech, value-added, and complex manufacturing where high competence can justify the high capital cost.
Negative Effect on Manufacturing
Reduced Export Competitiveness: A strong AUD makes Australian finished goods more expensive for foreign buyers, reducing the price competitiveness of exports.
High Domestic Wages/Costs: The high interest rates throughout the economy drive up the cost of capital and may put upward pressure on the price of labour (as workers are flush with savings), challenging high-volume, low-margin manufacturers who compete directly with cheaper foreign labour.
Conclusion on Manufacturing:
The SRD would not support the revival of old, low-margin Australian manufacturing (like basic textiles or volume assembly). Instead, it would force a powerful selection mechanism, pushing the country toward a highly advanced, competence-driven, capital-intensive manufacturing sector that produces goods so unique or high-value that their superior quality justifies the higher price tag imposed by the strong AUD.

The Fallacy of the Infinite Supply: Why the "Green Revolution" is Hitting a Wall
The modern energy narrative is one of boundless ambition: a "green revolution" promising to generate ever-increasing amounts of electricity from renewable sources to power an ever-increasing global demand. This vision, however, is a dangerous delusion—a monumental failure of logic rooted in wishful thinking, economic avarice, and a fundamental denial of the universe's most unyielding law. The current path is not a revolution toward sustainability, but a \mathbf{mad\text{ }race\text{ }to\text{ }stupidity} that mistakes sheer quantity for true utility. This essay argues that the focus on generating more power, rather than consuming less, is a catastrophic error. This failure is dictated by the unavoidable Wall of Entropy, amplified by the illusion of the human "Must" or "Want", and driven by Profit Motives that actively sabotage efficiency for the sake of cash flow. Our future is being actively stolen by an economic system that thrives on waste.
I. The Wall of Entropy and the True Source of Power The concept of a perfectly efficient energy system is ruled out by the Second Law of
Thermodynamics. This is not a negotiable theory; it is the Wall of Entropy—the absolute, non-negotiable principle that dictates all known physical processes. Entropy dictates that in every system, and in every energy conversion—be it solar, nuclear, or chemical—a portion of useful energy \mathbf{must} be permanently lost, typically as waste heat. It is why no engine can be 100\% efficient. The great irony of the solar dream is that it is a pursuit of diluted, second-hand power. Everyone forgets that the sun's power originates from \mathbf{nuclear\text{ }fusion}—the ultimate form of dense, reliable energy. Capturing a tiny, intermittent fraction of that energy with pollutant-heavy, resource-scarce solar panels is a wasteful detour. The \mathbf{Green\text{ }Revolution} attempts to bypass the Wall of Entropy by deploying massive, intermittent converters.
But this strategy immediately runs into two new, equally hard walls: The Resource Wall: These converters are not "green" in their entire lifecycle. They are \mathbf{highly\text{ }polluting\text{ }products} manufactured through energy-intensive processes using scarce, often toxic materials (lithium, cobalt, rare earth metals, non-recyclable fiberglass in turbine blades). To build enough renewables and batteries to power an always-on global economy is to trade one pollution problem for a vast, resource-intensive \mathbf{e\mbox{-}waste\text{ }challenge} built on material scarcity.
The Base Load Wall: Solar and wind are flows, not reliable, dense energy stores. To power continuous demand, such as exponentially growing data centers, they require massive, inefficient \mathbf{battery\text{ }storage\text{ }systems}. This reliance on batteries—which lose energy due to entropy during every charge and discharge cycle—exposes the logical fallacy of the entire approach. The notion that we can generate our way out of this dilemma is a scientific fantasy. The laws of physics dictate that the focus on supply will always hit a ceiling of efficiency and a limit of material availability.
II. The "Must" Illusion: Wishful Thinking vs. Reality The public discourse is dominated by the human, self-imposed "Must" Illusion. We are told we "must" transition to renewables, we "must" find a perfectly efficient storage medium, and we "must" power all future infrastructure using these new technologies. This "must" is not a physical law; it is a wish—a political or economic declaration that often overrides reality. The only true "must" is that entropy will increase. We already possess the \mathbf{dense\text{ }energy\text{ }resources} required for a reliable society: fossil fuels, nuclear, hydro, and geothermal.
A tank of gasoline holds \mathbf{50\text{ }times} more useful energy by weight than the best current battery technology. To deny the utility of these dense stores—and instead mandate a system dependent on intermittent, materially scarce technology, is to misallocate resources and capital based on a highly motivated hope. The \mathbf{human\text{ }must} is leading us to ignore proven \mathbf{base\text{ }load\text{ }solutions} that can be safely managed and conserved, in pursuit of an unreliable, inefficient, and polluting manufacturing cycle.
III. Profit Motives: The Robbery of Efficiency The final and most corrosive factor is the Profit Motive. The capitalist system is driven by continuous consumption, making the very idea of a long-lasting, hyper-efficient product an economic threat. We are being robbed of our future not just by pollution, but by planned inefficiency. The incentive to generate more power and to produce less durable, less efficient products is structurally embedded:
Selling Scarcity: A solar panel that only lasts 25 years and is difficult to recycle guarantees future sales and a massive waste stream.
Selling Failure: The pursuit of products that require high energy input (such as poorly insulated homes or inefficient combustion engines) ensures continued demand for both fuel and electricity.
Economic Entropy: This is the corporate equivalent of entropy—a system maximizing short-term profit through design flaws and planned obsolescence. This "stupidity for the sake of hoarding money" ensures that every technological stride we make is immediately undermined by built-in design faults that mandate more consumption and more waste.
IV. The Logical Path: Dense Power and Demand Reduction The logical path forward is to stop fighting the Wall of Entropy on the supply side and start fighting \mathbf{waste\text{ }and\text{ }inefficiency} on the demand side. The resources we need are the \mathbf{dense\text{ }energy\text{ }sources} we already possess. The real mission is to use them with maximum responsibility while simultaneously \mathbf{dismantling\text{ }demand}.
The foundational basis for future development should be a deep investment in \mathbf{nuclear\text{ }power}—the only reliable, high-density source that provides \mathbf{base\text{ }load} power with minimal material footprint and zero operational emissions.
This means prioritizing: Advanced Fission: Developing inherently safe, low-waste technologies like thorium reactors and Small Modular Reactors (SMRs), which utilize highly abundant fuels and offer significantly reduced waste challenges compared to traditional uranium reactors. The True "Solar Dream": Pouring resources into the \mathbf{magical\text{ }versions\text{ }of\text{ }nuclear\text{ }energy} currently being developed—fusion power. If realized, terrestrial fusion would perfectly mimic the sun’s process, providing near-limitless, high-density energy that respects the \mathbf{Wall\text{ }of\text{ }Entropy} by offering maximum energy utility from minimal material input. By coupling this shift to dense, reliable generation with an unwavering focus on \mathbf{Demand\text{ }Reduction}, we create a sustainable, resource-conserving economy: Prioritize End-Use Efficiency: Achieve greater gains by creating robust, repairable, and energy-miserly products.
Adopt Base Load Pragmatism: Use dense, reliable sources (\mathbf{nuclear}, \mathbf{hydro}, \mathbf{geothermal}) to power a stable grid, stretching finite resources while the true, sustainable \mathbf{nuclear\text{ }dream} (fusion) is realized. The true energy revolution is not about generating more electricity to feed the wasteful machine. It is about reducing the total energy appetite of humanity through ruthless, uncompromising efficiency and building our foundation on the densest, most reliable power source: the atom. Only by respecting the Wall of Entropy and fighting the economic motive for waste can we free ourselves from the illogic of the "Must" Illusion and preserve a viable future.

That's an excellent question that connects the principles of thermodynamics (entropy) directly to real-world engineering. When talking about the most efficient internal combustion engine (\text{ICE}), internal combustion engine we need to look at both the theoretical limit and the practical application. The most efficient version of an ICE, in terms of converting fuel energy into useful work, is generally a large, low-speed marine diesel engine. However, among the types you listed, here is the breakdown: Efficiency Comparison of ICE Types The efficiency of any heat engine is fundamentally limited by the Carnot efficiency, which is based on the difference between the high and low temperatures of the operating cycle. Generally, higher compression ratios and higher operating temperatures lead to higher theoretical efficiency.
Engine Type Peak Thermal Efficiency (Approx.)
Diesel (Compression Ignition)
40\% - 45\% (Passenger Cars) 50\% - 55\% (Marine/Power Plant)
***
Jet Turbine (Gas Turbine)
30\% - 40\% (Aero) 40\% - 60\% (Combined Cycle Power Plant)
***
Petrol (Spark Ignition)
30\% - 40\% (Best Modern Engines)
***
Gas (Natural Gas)
35\% - 45\% (Varies)
***
The winner for raw thermal efficiency is Diesel, due to its fundamental operating cycle (the Diesel Cycle) which allows for much higher compression before ignition. The Jet Turbine in Cars (The Chrysler Turbine Car) You bring up the jet turbine, or Gas Turbine Engine, which offers a different set of efficiencies and challenges: 1. How a Gas Turbine Works A gas turbine operates on the Brayton Cycle (or Joule Cycle). It consists of three main components: Compressor: Sucks in and compresses air to very high pressure. Combustor: Fuel is injected and burned continuously, raising the air temperature significantly. Turbine: The hot, high-pressure gas expands through a turbine, spinning it. In a jet, the remaining energy is thrust; in a car or power plant, it is used to drive an output shaft.
2. Turbine Efficiency and the "Regenerator" The primary inefficiency in a simple gas turbine comes from the massive amount of heat exhausted (exhaust is the "low temperature" sink, increasing entropy). The Chrysler Turbine Car (1963-1964) and other automotive concepts tried to solve this with a Regenerator (or Recuperator). Regenerative Turbine: This device captures the heat from the hot exhaust gas and transfers it back to the cold, compressed air before it enters the combustor.
Result: This preheating reduces the amount of new fuel needed to achieve the required operating temperature, dramatically increasing the overall thermal efficiency and solving the problem of high exhaust temperatures.
3. Why Turbines Failed in Cars Despite the technical efficiencies gained by the regenerator, turbines ultimately could not compete with piston engines in automobiles for practical reasons: Fuel Economy at Part Load: A turbine's efficiency drops dramatically when operating at anything less than its optimal, high-speed setting. Piston engines, particularly diesel, maintain reasonable efficiency across a wider range of speeds. High Cost & Exotic Materials: Turbines require expensive, high-temperature \mathbf{ceramic\text{ }alloys} to withstand the extreme heat necessary for good efficiency.
Engine Braking: Turbines provide almost no engine braking, a vital safety and control feature for cars. Throttle Lag: Due to the inertia of the rotating components, turbines had a noticeable delay ("lag") between pressing the accelerator and feeling the power, making them poor for city driving. In summary, while a simple gas turbine is inefficient, a \mathbf{regenerative\text{ }gas\text{ }turbine} can achieve efficiencies comparable to diesel, but its poor performance outside of its peak power band and high manufacturing costs sealed its fate in the automotive sector. Diesel remains the benchmark for maximizing thermal efficiency in an ICE.
