10 batteries plus the original.
There is simply just nothing there in the engine bay!
I like it. Be great for offroad with that kinda torque!

It is only short range about 50km. The motor is a DC brushed jobie, (starter motor for a turbine) the brushless equivilant would have been about $5K and ESC similar.
He built it because since he was 16 he always wanted an electric car, he didn't build it to break any records, just for fun in his retirement.
OH them batterys were closer to $500ea.
Yer I though the energy rating sticker was a nice touch.

Cam, think it is now called a motor bay

with room for a back pack or two under the bonnet. A light weight little genny would go well in the tray to beat walking off looking for a lead. A very tidy looking conversion. I'd hate to think how much petrol was when old mate was sixteen - must have been his motivation for his dream.Thanks fer sharing pics

I Like it ... t'was thinking of doing something similar ...

... hmmm, more thought's / info needed.

I also like the idea of keeping the motor, but putting in an 'assist' electric motor in there somewhere ...

This is the thing with electric vehicles for me: recharging takes time and their ability to cover distances is not what we're used to. I like the ability to drive 5-600km in one go, more if I'm refilled, which is quick compared to having to recharge.

In terms of environmentally friendliness - well, these new mass produced hybrid vehicles are a tad more un-environmentally friendly in terms of energy used from construction through consumer use and then onto the destruction phase - based on an average lifespan of 125k km (WAY low in my opinion!). The conventional internal combustion engine just wins out. But if the batteries need a change in the life of the hybrid you're looking at the internal combustion engine coming in much more environmentally friendly than the hybrid.
In this case it's not a hybrid - but it's kind of the same with a lot less range

Kudos to knocking up his own system though!

Cheers

Hence why everyone drives internal combustion driven vehicles. I think they had it right in the 1890's and early 1900's; the "gas" station is actually a battery station where you drive in, swap batteries and drive out. Might even be quicker than filling up with petrol

Just wait until the real green fuel is availabel at the pump - algae juice. Not sure why but I think it will require a diesel style engine to run ....

Hmm ... A brushless electric motor + ESC + Storage device ... Sound's a familar theme from my RC days ...

Allthough the technology behind it has advanced in the last few years with greater capacity + better engines etc ...

Another thought occured to me : With a 'water' fuel cell ( where energy is stored as water, then processed when needed ) if you could get one big enough + suitable for 500 Km, would it be a viable option ...

the only way energy is stored as water is to use gravity!

MMMMMM...electric Brumby.

If its white....wonder if you can get discount off your white goods insurance?

What about heat?

looks really good a great effort all round

the dizzy looks like it is an EA82 thats been modified to fit.

My grandfather was telling me of an old guy who lives in Perth.
He was going clockwise round Australia in an electric MG B with the wife.
He gets about 300km per "tank".
He's about to finish and start again going the other way.

Wonder if going around Oz the other way will recharge the batteries rather than discharge them?

Just a bit of lateral thinking there!

I'm pretty sure I've heard of this guy.... is it blue? If so I've met the guy.. HIs wife drives a VW as a backup car...?

Not sure on colour. Yes I believe his wife does drive a backup vw.
My grandfather met them in the Esperance caravan park.

In refering to Fuel cells : http://en.wikipedia.org/wiki/Fuel_cell

There are many ways to store & retrieve energy ...

However the most efficient & cost effective one has yet to meet the market ...

still wrong, if you read the wikipedia why still the fur-fie water fuel cell?
water is a waste product in the fuel cell, water is neither the energy storage media nor the fuel.
sorry I get a bit pedantic about inaccurate descriptions where electrikety stuff is discussed.

what about Dams? they are old school, but very efficient and cost effective, but greenies won't allow them.

luv the electric brumby. I expected to see more batteries, so what depth of discharge is happening for the 50km range I wonder.
pitty now electricity costs so much more for the recharge...
