Home Made Batteries

Here is a fun little video on how to make batteries from pennies, cardboard and vinegar, or pennies, washers, cardboard and vinegar.  Oh, and of course, electrical tape.  Seriously this could be a handy thing if you badly needed a battery.  It's probably  a lot easier to keep some extra batteries around the house, but this was pretty impressive anyway.




This guy has a lot of interesting things on his site.  This project reminded me of Phoebe's brother melting things....  :)

Fuel Pump Protection

FYI: In order to help your in-tank gasoline fuel pump to have adequate cooling and not to suffer damage, try to run on the top half of the tank.  If the distance to payday is just too great, run above 1/3 or even 1/4 full.

Pump replacement is not easy, or cheap, and pumps not only need adequate suction head (gas level in the tank) in order to operated without damage, but they use the gasoline to cool the motor.
