Albert Einstein's Famous Inventions

The most influential physicist of the 20th century, Albert Einstein made numerous contributions based on his theories that have benefited the world. While he was not an inventor by trade, Einstein invented a refrigerator that functioned without electricity. It may be adaptable into an eco-friendly version 70 years after he invented it. Many of Einstein's "inventions" were his theoretical concepts that laid the groundwork for future scientific research in other fields.

Special Theory of Relativity(STR)
Einstein's major contribution as an inventor was his theory of relativity of e=m*c*c, the relationship of energy and mass. The formula played a critical part in the development of atomic power that lead to the creation of weapons used to end World War II. Although Einstein did not design the atomic bomb, he encouraged President Franklin Roosevelt to develop and use it before Germany did. Atomic energy had led to new technologies including its use as a power source.

Quantum Theory
Einstein proved that light consisted of microscopic particles, photons, that contained energy that, when harnessed, produced heat. The energy is in proportion to the frequency of the light wave. His theory dealt with the atomic and subatomic systems, a deviatic classical theory of physics. Einstein's theory laid the foundation of quantum mechanics that developed, among other things, the superconductor.

Refrigerator
The only product Einstein invented was an absorption refrigerator that used no electricity. He developed it in 1926 with a former student, Leo Szilard. The Refrigerator had no moving parts and operated only with a heat source such as a gas burner. Designed for use in underdeveloped countries, Einstein and Szilard patented the refrigerator in 1930 in U.S.in 2008, engineers at Oxford University created a prototype based on Einstein's refrigerator design as a possible eco-friendly version.
