Re: (ET) Electric Tractor Conversion Update

Interesting article- two points:

I didn't see a date, but the examples use $1.50 /gal gas. The author 
does state that higher gas prices do make the economics of the hybrid 
better.

At the end, the author says:

"And of course, though you never have to plug one of these babies into 
your wall socket, there are compromises -- such as less power -- you'd 
do well to research."

One - they don't have less power compared to their non-hybrid 
equivalents, but I thought it interesting that it was implied that not 
being able to plug one of these into the wall was a good thing. If you 
could plug it into the wall the economics changes dramatically in favor 
of a hybrid, esp if you have a short commute. In fact, people have spent 
many thousands on conversions to allow them to do just that.
