With 62% of the energy going to wasted heat how can it be recovered?

	A turbocharger captures some wasted heat so a smaller, lighter, lower friction engine can be used to produce the same power.
	In 1834 Jean Peltier discovered the fact that a pair of junctions between two different material conductors (1 & 2 in Schematic) with one hotter  than the other would produce electricity!  Over 40 years ago in an Energy Conversion Course my Professor predicted that transistor junctions would make the process far more efficient.  It's what allows the pilot in gas appliances to generate electricity to operate the control!  Perhaps one of you will develop these systems to charge a battery in a Hybrid car!  It is being used to produce electricity in gas fireplaces, water heaters etc to generate the electrical power for the pilot and flame controls.  it's referred to as a thermopile. The principle is also currently used in reverse to make sold state thermoelectric refrigerators.
	Braking adds another 5.5% wasted heat!  Hybrids collect some of that  energy.   How about mounting a 250 amp Chevy Truck alternator (photo left, $299 new) to the driveshaft though an electric clutch that only engages  when the brakes are applied.  That's 3000 Peak Watts or about 4 HP!  That will slow down the car by charging a pair of deep cycle batteries connected in parallel. These could run electric power steering and air-conditioning!
	We can certainly save most of the 17% waste when idling and coasting by shutting off the engine!  Remember we used electric air-conditioning and power steering and that pair of deep cycle batteries can operate the radio too!

One Internet report indicates  tests and analysis using an EPA defined driving cycle showed that 10% of the energy goes to friction in various components.  It should be possible to reduce these losses.

	Coatings are being used in many racing engines, why not more in conventional motors?
	The use of synthetic high performance lubricants should help.  Quantified data is needed not just marketing hype!
	The Continuously Variable Transmission (CVT)  in our Nissan Murano works great and avoids all gears.  It also keeps the engine at the ideal operating rpm!
	Composite materials and ceramics should lower friction considerably.

Rolling friction uses a great deal of the energy. 

	Can tire companies develop lower rolling friction products that still perform?
	Can the tire pressure be varied for highway driving where higher pressures reduce rolling friction?
