I wonder how much energy you could get from simply enclosing an ACRE of land.... and making the whole thing out of plastic sheets like a greenhouse. This is a neat idea.

]]> Comment on Ford testing ethanol injection with Ecoboost by Roger Monger http://www.jmuafv.com/blog/2008/09/04/ford-testing-ethanol-injection-with-ecoboost/#comment-9 Roger Monger Sun, 07 Sep 2008 14:10:50 +0000 http://jmuafvlab.wordpress.com/?p=31#comment-9 Dan: You bring up a point that has confounded engine designers for years. It is a well established fact that higher engine temperatures result in a more efficient engine. That's why years ago pressurized coolant systems were introduced. Some think it was to prevent the loss of coolant, but that was a side effect, as it were. The primary reason was to raise the coolant temperature and thus the combustion chamber temperature and thus the efficiency of the engine. But along with higher temperatures came preignition and detonation, or "ping," requiring the higher octane gasolines of 40 years ago. At one time, Sunoco offered 99 octane gasoline in its famous blender pumps where you could choose multiple octane ratings. Then the '73 and '79 oil crises, the EPA, CAFE standards, fuel economy standards, et.al, came along. Engine designers were faced with the necessity to design high temperature, high efficiency engines that didn't "ping," didn't pollute, and got high fuel mileage. This ethanol injection idea is an outgrowth of that. The idea being to cool and quench the surfaces of the combustion chamber below the ignition temperature of gasoline to prevent "ping." Dan:

I can't imagine that it would cool down the cylinder walls very much or keep the engine cooler, but that leads me to the idea .... why not simply cool the engine block more using radiators or actual compressors / coolers?
