Alright, I don't have the time, energy, or room to do this, but I am throwing an idea out that I think could benefit all us North West Tree Huggers.  Why not do a biodiesel vehicle?  I know there are 720's out there that did it (a 1982 model to be exact) but I wonder if that engine would bolt directly into a 620 510 or 521 ect...  I am going to post a "Dirty Jobs" video on guba later on with the info on it.  What kind of ideas do you Datsun lovers have for alternative fuels?

I've seen the 720 diesel and it should fit a 620 even a 521 I'll bet. The frames are so similar I have an '82 under my '78. The diesel uses a different tranny bolt up (I think the starter is on the driver's side) so you will need to get the transmission with it. They could be turboed for a bit more power.
The '81, '82, and '83 had a SD22 diesel and the '84 through at least '87 had the SD25  diesel.

Well I stumbled across this while googling.
I know its not biodeisel, but it is an alternative.
Just erect a wind generator or a couple of solar panels, behind your house and it'll cover the cost of recharging.

I saw that article a few years ago. Batteries have probably come a long way since '92. Specially their weight. Bet it's 'heavy'.

I would like to know it's weight, is the 'motor' connected to the stock transmission or direct, a cost per mile to operate, and does it use regenerative braking: on slow down, using the vehicle speed to turn the motor to produce power and feed back into the batteries to re-charge them, thus re-claiming power that would otherwise be lost heating the brake shoes.

Well, I don't think the technology of regenerative braking existed in `92,  and "Curb weight.....1600 KG", which would likely be less today with new batteries.  And I have no clue on the transmission.  It would be cool though.  When I first read it I was wondering what the traveling range for the vehicle was.

Sad thing is that after the war, the Japanese made electric cars for a while...
just imagine if they had stuck to it!
