I am "green" to the subject. I found a tractor built in Russia that is a diesel electric power unit that claims to do the same amount of field work on 15% less fuel which I suppose is an net energy gain from not having a transmission. The start at 360 hp. 10 times what I was looking for.
I did learn that they (Solectrac) have a quick attach loader coming soon from Westendorf in Onawa Iowa.
On the water discussion I have friends in the tractor pull game that tell me they can pull up to 3 lbs. of atmospheric water per gallon of diesel.
The 1.4 gallons of water from a gallon of diesel figure I was using came from this website.
I did some poking around at a couple of electric car dealerships. The mechanics dont like the EV's because they only come in for brakes and tires. The salespeople are ambivalent. I did talk to some EV owners and of course they sold themselves. Their only thing on their wish list is longer fun times and more plug in locations on the highways. They have to carefully plan their trips around places to recharge.
Thanks for the reply
