Many people in this world want to store milk, vegetables, seeds and medication in a refrigerated atmosphere but the problem all over the world is shortage of power. Using thermoelectric cooling we can make a refrigerator easily.

The main advantages of a Peltier cooler (compared to a vapor-compression refrigerator) are its lack of moving parts or circulating liquid, near-infinite life and invulnerability to potential leaks, and its small size and flexible shape (form factor).

For anyone who is not familiar with the peltier device – it is a heat pump that is made like a silicon chip. A DC electric current will get the chip to “pump” heat to one side of the chip leaving the other side cold. Heat sinks (and fans) help to distribute the hot and cold.
