Re: [Electric Boats] CNG/Tri-fuel Generators?



Boy was that way more than I ever wanted to know! :) But thanks everyone!

One thing not mentioned, but maybe everyone knows - CNG is lighter than air, like hydrogen. So it's not quite as safe as diesel, but way better than gas or propane which can get in the bilge or near sparky motors and go boom. So CNG does not (I think) require a vented locker like propane does.

And for (bigger) boats CNG is easy - most good chandlery's here in US just do a tank swap for you. There is a re-fill station here at the airport as well. I have space (a wet locker that is usually dry) near where a port for the generator would be convenient. And then having a CNG stove/oven be an option was attractive.

But...I need to find out the total energy capacity in BTU (or something I guess) to compare to a gallon of gas and get some idea of runtime on the genny based on x lbs of fuel.

I still wish cheap fuel cells would have been here by now (along with my flying car)

Thx
