Thanks to not so new concept conversion from petrol or diesel could be easier and cheaper then we tough ( in nearest future).
Instead of trying to fit electric motor and connect to existing power drive, remove all together and attach new wheels with inbuilt electric motor already.
Concept is so cleaver because also allow for broad competition between wheels manufacturer, regardless of any big car manufacturer willingness to capture or dominate the market.
You still may have your favourite brand car - Mercedes, Holden or Toyota but wheel with wide power range of inbuilt electric motor, you could choose like tyres today. Michelin looks promising and since 2004 when concept was presented the time is coming...http://www.hybridcars.com/technology/protean-continues-campaign-wheel-electric-motors-30599.html
Unlimited recharges, no toxic chemicals, no heavy metals
no brainer really

30kw per wheel? So you would need 10 wheels to get 300kwatts.
That would look a bit silly. 
The PML mini has 4 X 120kw hub electric motors. Goes 0 - 60mph in 3.7 seconds. Each wheel assembly weighs 24 kg, replacing the original hub wheel and brake assembly that weighed 22.5 kg. Uses the original mini suspension. I presume they need such powerful motors to be able to pull up sufficiently well on regenerative braking. The super acceleration is maybe just a byproduct of wanting to do away with traditional brakes altogether.

the home made hydrogen-on-demand mods people have added to their cars look interesting.
since my surfing cars worth nothing, i thought i might try putting one on and see if it works 
so simple, even uncle hick billy bob can install it as in this video, finds a new use for his bong, and he fully endorses it
Electric motors are also rated where the motor can produce 30kw continuous, not peak. Peak will be much more but obviously only for a limited amount of time.
A 30kw petrol engine is rated at its absolute peak power, if producing this power for a long amount of time would cause engine failure anyway.

before you post negative comment on this, think nobody ask you to trade your SUV or ute on eggomobile, since the comfort in live is the most important you truly deserve (for the most), but as alternative to crowded trains, buses - at similar or cheaper costs to use - that can be seen as improvement.
Maybe hire like bikes now ?
Don't need helmet at least
For the hydrogen nonsense to work it would have to defy the laws of science.
Talk to me about affordable batteries that hold a big charge then electric cars will be worthwhile but only because they can't tax the fuel like they do petrol.
If you think a bit, imagine that in developed countries very soon everybody want one 4 wheels vehicle as we have.
Give them 12 cylinders or eight at least (because that desire for power under the hood is conversely proportional to grey matter under the scalp)
Multiply that by 2 or 4 billions at least to see the scale of the problem.
I would rather see them in eggomobile. You could fit 14 in one car park space, or take to your appertment in high rise skyscraper if fits into the lift only
The Egg Mobile is WRONG !!! Looks like the most dangerous vehicle I have ever seen.... Top heavy... decent side wind would topple it over...
Scooters will be amongst the last gasoline vehicles left running... Simple, and cheap, and they work.
My money is still with "light carbon fibre three wheel mountain bikes with lightweight shell, electrically powered". In short, it would be an U-CAR. Ultralight Car.
You only need about 2kW of power, and the whole thing can be as light as 100kg. The physicists in the room understand that a 100kg vehicle will use considerably less energy than a 1500kg vehicle.
Here's my two favorite electric light weight vehicles.http://www.abc.net.au/tv/newinventors/txt/s2909593.htm

Plus the dirt bike industry is adapting to noise complaints... They are are developing electric bikes will virtually ZERO noise, other than a low hum for the electric motor, and the quiet splatter of some gravel, grit, and mud hitting the mud guards!!
VW has been working on the L1 for a while. The design criteria is an acceptable car that goes 100km per litre. It's a good looking car to boot.
