Current models as in those Elitist high street cruisers , techninally not a problem. Any model LandRover is suitable for conversion but it will be cheaper to buy EV from the Factory, I would only bother converting something special that you intend to keep long term.Quote:

Why ask a question when we all know the answer?[tonguewink]Quote:

And its not only where it will come from,who is going to do the massive investment in the infrastructure to distribute it.
Using oil to generate power would certainly go well with those that are trying to get away from using fossil fuels.

That's the same people who will invest in the stuff needed to replace fossil power, i.e. corporate investors.
It was just an improbable example of possibilities if you imagine an improbable scenario of difficulties. [bigrolf]Quote:

Quote from Stand by, Australia, for the electric car revolution
"One of the challenges that will come from the big increase in electric vehicles in Australia will be the demands on the electricity grid. An extra one million electric cars is the equivalent of 5.2 terawatt hours of power demand. This is about a 2 per cent increase in overall grid demand."

In the past, the government paid twerps like me to build the power stations. Now all those have been sold off and most of the power stations are at the end of their lives, so it will be up to big corporations backed by their shareholders to come up with viable solutions. I'm pretty sure none of them will be firing anything with oil.Quote:

an 11kva is just on the money.
Weight and acceleration becomes an issue and the napkin maths says its not really any more effeicient than when you have a normal diesel..
however,
couple that you dont need to always use the generator so can leave it at home if you're only doing short trips, you can still charge from almost anywhere if your onboard charger has leads and... if you set it up right you can just hire the generator for the trip you need it for...
and it becomes a far more attractive idea.
True Dave, I was working on the assumption of no Batteries, just straight Diesel Electric.
Adding batteries makes it so much more attractive proposition.
Well, range extenders aren't that large - the BMW i3 range extender is just 647 cc - from Wikipedia:Quote:

7.2 L (1.9 US gal) in the U.S.[4]
Also, I'd wondered why range extenders were so efficient:
"As an REEV is only propelled by the electric motor it can do away with the weight and cost associated with the gearbox transmission system typically used in internal combustion engine cars. Further, as the range extender does not need to increase or decrease output in line with the power needs of the vehicle (this task is handled by the electric motor) the range extender can be sized to satisfy the vehicle's average power requirement rather than its peak power requirement (such as when accelerating). The range extender can also operate much closer to its most efficient rotational speed. These design features allow an REEV to convert fossil fuel energy to electric power and vehicle motion very efficiently."

BTW, if you're thinking that cars plus aircon will be a problem, on really hot days in the future a lot of houses will run off their car's batteries - this is what happens in Japan now - so they'll actually assist with network demand. And with the uptake of household batteries there will soon be a lot of stored capacity off the grid in any case.
