Foot and Car

In my home there is there is a concrete step Infront of the front door, I like to keep that step clean because I take my shoes off when I get home from work and put my feet on the cold step. I sit there and wait for a while. Waiting for my coffee and my feet to cool off. 

I am also waiting for a genius to invent the low cost high capacity battery so electric cars can become very cheap. They have no exhaust pipe, no fuel pump, no clutch, no oil filter, no oil pump, no coolant system, no cylinders, no cam shaft, nothing, Just an electric motor and batteries. Electric cars are only expensive because of the high capacity lithium batteries they use. If they invent a cheap battery system then everyone can buy cheap electric cars with very few things to go wrong.
