Re: Replacing IC engine with electric motor
The numbers just don't work. The problem with electric power is that it takes roughly 100 time the weight in batteries as diesel fuel for the same amount of power. So assuming you currently use a gallon an hour, figure you need 650lbs of batteries to replace that one gallon.
If all you want to do is motor in and out of a harbor, then electric power will work. Otherwise there just isn't enough energy density in the best batteries to come anywhere close to fossile fuels. If you want to be green, run bio-diesel instead.
