Electric cars are not fast to recharge; they are slow. Cold fusion would do nothing to change that. Even if electricity cost nothing, electric cars will still be slow to recharge and they will still have a limited range because of the weight and bulk of the batteries. The cars will still be expensive because the batteries are expensive. > Even exchange of batteries is a possible way. > This would cost tremendous amounts of money to implement on a large scale. > I really do not care for to have the reactor in the car.

If they are only as safe as today's gas-fired and coal fired generators they should only be used on a gigawatt scale. If cold fusion reactors are safer than today's gasoline powered motors they should be used in cars instead of those motors. Gasoline fueled vehicles are not particularly safe. The fuel is toxic, and it often burn in accidents. They pollute the air, and cause global warming. > Neighborhood power stations. 20 homes or similar. > I do not see how this would be any safer or more cost-effective than installing one generator per house. If the power station is safe enough for 20 homes surely it would be safe enough for one. > There are many advantages with that as I think we all can see.

It would be far cheaper and easier to implement. No infrastructure is needed.

That, plus the high cost of batteries, is why they have such short ranges, such as 84 miles for the Nissan Leaf. - Jed
