Be interesting to see more tech on that - Range being the one that I am curious - E.g If I run low on premix, I can pull in, top up & drive off.

If my battery goes flat, I pull in...... how long would it take to recharge?


And I won't go down the "how green is half a ton of lithium batteries by the time you have lugged them around for 9 years, mined & processed the ores, then have to dispose of half a ton of toxic waste, and recharged them with whatever percentage of the national grid is still coal fired.....

Backup petrol generator?

Speed, range, run time


According to the above page the range is still far short of ideal. I suppose you could always use fuelcells to increase the range and use ethanol instead of petrol...

Whilst I like the steady march of technological innovation I think there is still a way to go before this is of any real world use.

Great to see any new developments, but the jury is still out for me. Look at this standard Mk IIC Zodiac. The battery doubles as the bench seat!

Has the feel of a Goldfish RIB video.

50 kg of "juice" gives 13 nm @ 12 knots.

If i was a canal boater that tech is beginning to become viable - i would have plenty of space to put lots of batteries, the weight would be relatively insignificant, and i would be a lot closer to power to recharge them, but in the word of ribs, even my 30yo tech can eek 75nm @ 21knots from 50 kg of "juice"... without needing to stop every 10 miles to refill.

As battery power density improves, this tech will become ever more viable, but i still have concerns about the "overall life green-ness" by the time you make, charge and dispose of the batteries.

Me too. Green technologies only ever seem to be talked about as end-user cost rather than total cost

Nobody ever looks at "whole life" costs when assessing battery powered vehicles.

My friend recently bought a Toyota Prius (hybrid car) We did some calculations and taking everything into account from manufacture to disposal, my Land Rover Defender is more environmentally friendly!

An extreme example I know, and helped by the lifespan of a Defender, but true nevertheless.

Not to mention when people try to rationalize the expense of turning an older yet still running vehicle into te scrapyard in favor of a newer more fuel efficient car (often incentivized by various "green" government programs eg. Obama's "Cash for clunkers" fiasco).
A person might want a new car for a variety of reasons, but to claim that it is for the environment and emissions reductions is ridiculous. How many extra commutes to and from work does the purchaser have to make to earn the extra money to pay for the cost of that car? How many extra commutes to the auto plant workers have to make to build the new car? What was the environmental cost of obtaining those raw materials for the new car?
You can be sure that any time the government spends your money on some kind of "green" initiative, it will have a negative impact on the environment reather than positive.

The company I work for helps develope flow batteries. So a small battery is feed by the charged electrolyte held in a tank. If it will ever develope to a point where is is practicle for vehicles has it's issues...
