The other day I was pondering the problems of keeping a car battery charged up in cold conditions. Then I had a brain wave. I thought of something that would make me a fortune and solve a long standing problem.

My idea was a self heating insulated battery. It wouldn't take much power out of the battery to heat itself so could even be a success in electric cars especially in places like Canada where cold temperatures are consideration for their desire to develop electric vehicles.

Then I looked it up on the internet. Guess what?

You got it. Someone has already put the idea into production.!

Oh well, keep dreaming.

Recently saw a piece on building your own trickle charger...

Spare power pack - 12v, .5A, maybe an odd resistor.
