Problems with the current Engines

• Less fuel efficient.
• Pollution.
• Cannot perform at high temperatures.
• Requires lubrication and not wear resistant.

3
Alternatives and their limitations

• Fuel-cell electrical engines.
• Very heavy. 300kW engine weighs 8000kg.
• Solar cell electrical engines.
• 100kW power requires 1000sqm.collecting surface.
• Steam-powered turbine engines.
• Coal is very polluting.
• Electric engines.
• Cannot run a great distance and need recharging.

Gay-Lussacs Law

• P.V n. R. T.
• High pressure is required to get maximum power.
• By increasing the temperature, high pressure can
  be obtained.
• Metal cylinder operates about 1000K.
• Ceramic engine can operate about 3000K.
• Increase in power by factor of 3!!!

Properties of Ceramic Engine

• No lubrication.
• No cooling.
• 150 more power.
• More life.
• 75 lower fuel consumption.
• No pollution.
