Electric cars have many types and each of them has different influences. In one thing, it is for children. They are popular in amusement parks. They can make children feel fun and happy.

Some Drills that are used in underground mining of Potash are generator powered electric motors 500,600 and 700hp they are very powerful.

There is a professor in CA that is working on a new type of solar cell techology based on nano-carbons (current solar cells are silicon based). He notes that within 10 years, this technology will be multiple times more efficient and current cells and could even be mix into paint (any color). So your house or car could litterally be painted with solar cells.

Whoa!

it'll never be 100% clean.

 what are the biggest eletric motors? i dont ever fore see replacing semi trucks, and construction machinery being replaced by eletric power.  it just doesnt produce that much power.

but i dunno, i just figure'd it was never feasible. i figure'd we'd do away with transportation period eventually and just make every one walk. :-p

One issue about commenting here is that you should check your facts before making a "drive by comment".

All of the Diesel powered trains you see are powered by electric motors.  The Diesel engine is only used to charge the batteries.

I have also questioned dumping the problem of charging all of the car bateries on the electric grid.  Like we don't have enough probelms with the power grid in California.  It seems a better option is to get as many people as possible to install Photo Voltaic systems on their homes and use them to charge the batteries (as well as run the household  electric items).  This could be done by charging a spare battery during the day and changing it out at night, or some kind of storrage for the PV system.  Batteries are continually improving, and should be able to handle the distance of a normal commute.  We need to get going on this soon!

I think you should practice what you preach and check your facts - charging the batteries off the electrical grid will actually make the grid more stable. Since the car is parked (and thus connected to the grid) 22 hours a day, the cars can recharge during off-peak time, and during peak hours they can help the electrical grid deal with power consumption spikes by feeding back into the gird some of what they took during off-peak hours, returning the power in a distributed fashion, preventing brown outs and rolling blackouts. Also, 100% of the power that Better Place buys for charging the batteries is renewable.

I have to say that I usually do practice what I preach.  First I had heard of "Better Place" but had not done full research, however, it does seem to be "Pie in the sky" right now. so I don't think you can use the word "FACTS" here.  Maybe checking "PROPOSALS" would be better. 

 Still not sure this is the best way.  I am a "Mother Earther" from way back and would prefer to do my own, rather that depend on someone else.  Until, and unless their vision is implemented, if we suddenly start plugging in cars on the grid, it will be a problem.  One of the things that happen in the real world (as opposed to a sales brochure) is that the peak time for electricity varies.  In places like Phoenix and Southern California, the peak time can last well into the evening.  If you plug in during that time the grid would be toast.  There probably are ways to get around this, but it is not as easy as the presentation makes it.  Also, I believe that the more we spread around the generation of power, the better off we are.

My thrust is to start enabling all of us to generate power, photo voltaic, wind, bio, etc. and do it soon.  The how to distribute can come as we proceed.  If Better Place can make it work, then it should, and will be, a player.

The thing about this, is instead of using the fuel in your cars the power plants will have to use it to make the power for the batteries. So moving the burden of the fuel from one place to another will not solve the problem. Are they going to use solar panels to charge them during the day? Are they going to use hydro &/or wind power?

When a car is powered by electricity, you have the option of generating that electricity using renewable energy sources. With standard cars, you don't even have that option. 

Say 10% of your country's electricity is clean - that means that your car is inherently 10% cleaner than a traditional car (operating efficiency aside). When your country gets to 30%, your car magically gain that same advantage. A car based on fossil fuels will always be 0% clean, no matter what efforts your government puts into green-ing up its electricity.

Also, this 4 minute video really sums up what Better Place is about: http://www.betterplace.com/press-room/videos-detail/whats-better-place/
