Abstract: A medical grade cooler or freezer uses a Peltier system without the use of vapor compression refrigeration. An opening may be cut through a wall, for example, a top, bottom, rear or side wall, of the cooler or freezer and the Peltier device sealed within that opening with the hot side exposed outside of the cooler or freezer and the cold side exposed inside the cooler. When a voltage is applied to the Peltier device, the interior temperature of the cooler may be reduced. The Peltier devices can also be reversed by applying voltage in the opposite direction to remove heat from outside of the cooler and pump heat into the cooler or freezer.

Abstract: Convenient anodizing is provided through a pen form factor anodizing tool having a reservoir for holding anodizing fluid and an electrical cable connection communicating electrical power to a tip dispensing anodizing fluid from the reservoir at a anodizing voltage from electrical power through the electrical cable connection.

Abstract: A Peltier system can be retrofit to a standard cooler. A thermal conductive material passes between the cooler lip and the lid to provide a heat pipe communicating between opposed Peltier devices, a first device positioned within the cooler and pumping heat into the heat pipe and a second device positioned outside the cooler and removing heat from the heat pipe.
