Reply #10: Actually, this engine can be scaled for any size car or truck.

The Oak Ridge National Laboratory estimates we could produce 1/3rd our total transportation fuel requirements from bio-fuels (i.e. Ethanol).

NOw, this engine improves fuel economy 30% while using only 5% ethanol and 95% gasoline.

What this means is if all the cars on the road were using this engine It would take 5% of the fuel supply (in the form of ethanol) to reduce gasoline requirements 30%.

Now you still have 28% (33% - 5% = 28%) of the fuel supply (as ethanol) to displace gasoline by substitution. That means the total reduction of gasoline consumption would be 30% (from improved fuel economy) + 28% (direct substitution of ethanol for gasoline) for a total reduction of 58%.

... and this at an additional cost of $1,300 per copy (I think the extra $300 may be for additional technology enhancement other than the Ethanol direct injection). This is much more affordable to many more people than hybrid technology or plug-ins so it would be adopted much more quickly, leading to faster GHG reductions.


At $1,300 extra for one of these you would get much faster adoption than you would for $3,000 to $4,000 additional for hybrids and $10,000 to $20,000 for plug-ins. Now, were going to need plug-ins and hybrids but until they are on the road in numbers this engine would be providing reductions in GHGs for less investment.
