switchgrass ethanol delivers 540 percent of the energy used to produce it, compared with just roughly 25 percent more energy returned by corn-based ethanol, and emits significantly fewer greenhouse gases than ethanol made from corn.
What about the compressor runs off a hydrogen battery cell, or something like that? All this ethanol is going to drive up food costs like crazy. Already happening.

I thought the 540% more was a typo. But it wasn't. Wow.
I still prefer the air car.
the perfect car is the air car with an ethanol-based compressor charger engine when an electrical outlet or compressor station is not available.

thats one of the advantages of switchgrass, as mentioned in the article, in can be grown on land not normally used for growing food.
as for the hydrogen battery cell, the hydrogen needs to be made somehow, some energy source is used to extract hydrogen from water.
