History of Solar Energy 1767‚ First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven‚ reaching temperatures of 230 degrees fahrenheit. 1839‚ Photovolataic Effect Defined In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect.

Robert Oppenheimer. Better known as the "Father of the Atomic Bomb‚" Oppenheimer‚ though succeeding Bohr and Heisenberg by actually putting his work into practice through the Manhattan Project and development of the nuclear bomb‚ was a peer of both Bohr and Heisenberg in generation and in study‚ devoting his early career to theoretical physics. Although the three men were representatives of different‚ often conflicting groups (as the Danish Bohr was considered a Jew‚ German Heisenberg aligned himself

Savannah Hudon Mrs. White English IV 2 February 2014 (Intro) Solar Energy is an underrated renewable energy source. We should be looking to make advances to become more dependent on renewable energy sources such as solar energy. The more we rely on these new energy sources the more carbon dioxide‚ sulfur dioxide‚ and other greenhouse gases we could eliminate from the air which will help ensure a clean and safe environment for future generations. In addition‚ it could aid America to depend

The Structure of Matter There is a large overlap of the world of static electricity and the everyday world that you experience. Clothes tumble in the dryer and cling together. You walk across the carpeting to exit a room and receive a door knob shock. You pull a wool sweater off at the end of the day and see sparks of electricity. During the dryness of winter‚ you step out of your car and receive a car door shock as you try to close the door. Sparks of electricity are seen as you pull a wool blanket

Solar powered cars have been said to be the future of renewable transportation and that they are supposed to be economically efficient and environmentally friendly. Though it may sound like pure science fiction‚ there is development happening around world that is bringing that notion into reality. As I researched thoroughly to create my conceptual model for solar cars‚ I asked myself this: Are solar vehicles even practical for the U.S.? Solar energy is the most abundant energy resource on earth

Following the discovery of the planet Neptune in 1846‚ there was considerable speculation that another planet might exist beyond its orbit. The search began in the mid-19th century and culminated at the start of the 20th with Percival Lowell’s quest for Planet X. Lowell proposed the Planet X hypothesis to explain apparent discrepancies in the orbits of the gas giants‚ particularly Uranus and Neptune‚[1] speculating that the gravity of a large unseen ninth planet could have perturbed Uranus enough
