Telsa Motors, the US company which makes electric cars, has unveiled a new battery it says can power homes using solar panels.

I’ve read into this and I’m really not convinced. It seems that if the more expensive unit is charged up fully it would power a washing machine for one wash. It could probably only power the average home for about 30-60 minutes and that’s pushing it!

I can’t see how anyone in the developed world could see any return on the product, the costs currently outweigh the gains. Of course, if the price came down to a few hundred then, perhaps it’s worth buying a group of battery packs to go along with your acre of solar panels!
