The technical trick is a smaller cylinder/piston in the middle of main piston. In operation, it is able to double the compression in the center cylinder to auto-ignite, miniature detonation. Then the flame front ignites the main charge without detonation. Some of us may remember Honda's stratified charge engine that had a central, enhanced ignition source into a lean mixture main charge. This is a similar approach without the central fuel injection and spark ignition.

The Carnot equation pretty well defines...

It does not take much observation to realize that a overcrowded highways have less capacity to move people because the cars slow down so much. If the highways could be packed and still move at the speed limit they would have vastly increased capacity to move people. Not to mention making a lot of people happy!

The solution is auto-piloted cars. With autopilot, cars can be set to drive at the speed limit (and a little above to close gaps) and at minimum safe distance. The entering and exiting of the vehicles and lane assignment would also be handled automatically by simply requiring the destination. Car lane assignment would be controlled by computers. Once a highway is at capacity, cars, simply will not be allowed to enter but the capacity to move people would be much much larger than it currently is with the same lanes.

Yes there will be many technical and political problems to work out. These problems need to be worked out and this should happen within the next ten...
