Electric Car In-wheel Motor Siemens ECorner

Look further back through the comments on this video, 'unsprung weight' has been discussed pretty comprehensively.

How significant of an unsprung weight gain for an in-wheel design vs. an inboard system?

I doubt there's any shortage of Uranium in Australia.

There are about 230 nuclear power plants in the world that use 80-100 tonnes of fuel to generate 900-1500MW. Only about 1/3rd of the fuel is replaced every 18-24 months so a commercial reactor uses only about 100 tonnes of uranium every 4.5 - 6 years and puts out 1GW 24/7. A coal plant of similar output power uses 10,000 tons of coal A DAY!

All the worlds' nuclear plants use less than 4000 tons of uranium per YEAR.

They're not stopping us but the expense is. To go totally off grid and not melt in the summer is VERY VERY expensive and most HOA's will not allow arrays on top of houses

Actually, there isn't enough uranium to supply alll of the world's electricity. Though i loathe Bush and his policies, he and his cronies aren't stopping you from adopting solar and wind resources. You should place the blame on your own government that seems to run lock step with the Bushies.

Close, 1898!

Didn't Ferdinand Porsche come up with idea around 1912?

Don't you just love technology. Australia has loads of uranium, no earthquakes and no population in the middle of its desert. We could source all the worlds energy from nuclear, and at the same time develop and use solar, because we have no boody clouds and so much sun 365 days a year in the middle of our country. Oh i forgot. George Bush and his croneys started a war so that the American Oils companies could screw extra money out of everybody

What we need is to get YOU a better joke book. Your present one is well, shall we say, lacking.

Yeah, I was going to try it with a remote controlled car or something. I guess all I'd have to do is make a chassis, wheels and the concept though.

Ju7st gotta find out a way to do it all.

You'll most likley have to build it mate. It's called 'proof of concept' even if it's just a small bench sized scale model.

You'd be surprized how much you'll learn by actually trying to make one run from scratch, what-ever 'it' is. Then you'll have something 'real' to show investors. Good luck and remember the motto for inventors is "NEVER-EVER GIVE UP"!

What I think the industry is doing wrong, is they only seem to be fixated on modifying current engines. I have an idea that's pretty good, would cost pretty much NOTHING to run, except for the regular things (WoF, registration, maintaining it) which aren't really related to the cost of every day running.

The only problem, my idea requires a whole new engine design.
I live in New Zealand, any ideas on where I could go to foward my idea on to investors etc?

Here is my question: if this car is driven with a wheel motor why does it even have a hood?

we do not need electric cars. we need to use petrol cars. our our money should be spent on petrol and poluting the air. we must make petrol companies rich. we must destroy the earth. we must waste our money. lets use fossil fuel till we ran out of it and make the earth temperature to near saudi arabia. we must not leave any energy for the future generations. it took earth billionsd of years to make fossil fuel. we must spend it all in one or 2 centuries.

yeah that would S**k to find this car up on blocks. but i love this company. they make the computer parts for my granite CNC. the only flaw with this system is the fact that no current electric car companies are thinking about solar power for some reason. all they worry about it how long it takes to charge and how much laptop batteries weight

No way! My Father and I made a RC car like this when I was a kid. It wasn't as elaboret and it ate it's duel 9volts in a matter of minutes. My father said that putting the engine at or in the wheels (4 wheel independent drive) isn't anything new it just never catchs on. I wonder if they would have the same problem as my toy car and it just eats up the battery too quick.

The system is still in the development phase, they say it will be on the market around 2010. Probably they still have to work on the software.

so why isn't this being produced ? batteries can have a recharge as you drive system.. no need for expensive batteries..

the fact that every American nerd can design an electric or other energy efficient car better than entire companies worth of planning and research proves that people are cool and the the government or maybe just the oil companies bribing the governmet are resisting change and destroying the environment. forget Rockefeller. i hate that fool. im goin to make my own car just to save me gas and ill always know what wrong with it. bill and ted robots could make a car at home depot so why can't i.

now that really is what you would call and expensive set of wheels. Haha.

What about theft...if the engines are in the wheels??!!

Look, you can't just generalise!

Lead acid batteries are in no way comparable to NiMH or li-ion cells.

To get 100km range with an EV with regen requires only a 9kw/hr battery pack of A123 Nanophosphate li-ion cells. The pack will weigh just 90kg and takes 5mins and $0.90 to fully charge. A pack this size will give a max output of 500hp.

A123 batteries have been sold in Dewalt cordless power tools for the past 3 years and the GM Volt will have a 16kw/hr A123 pack when launched in 2010.

The number of cells will be proportional to the weight, more weight equal more power to move the vehicule. For myself I do 2 x 90 km to go at my work (and I am not a specialist drive juste a computer scientist). I don't attack the electic car since I think they are the solution. But sorry for the battery or cells (dont play on the words) are yet the problem (heavy, expensive, and the load is very long).

They 'type' of battery has nothing to do with range, it's how many cells are in the battery. Have a look at the tzero videos on my channel, it has a 50kw/hr battery with a range of 300 miles (500km) on a single charge. To be honest unless you're a professional driver who spends all day every day on the road you are unlikley to need a car with that kind of range. It's commonly called 'range anxiety'

80% of drivers travel less that 40 miles per day.

Nice, just a batery problem yet. The best lithium polymere ion batery allow about 200km for a 125km/h range. (like the blue car). Yet another step ....
