A look at the scientist's breakthrough innovations, from the world's first solar-heated home to an electricity-free Easy Bake Oven Scientist Mária Telkes spent her life chasing the sun. . Abstract— The paper proposes an automated wheelchair which will help the physically challenged people and serve as a complete form of this automatic system (means of mobility). The most commonly used device for differently able peoples are wheelchair. [1] She moved to the United States in 1925 to work as a biophysicist. A large number of persons with disabilities come from impoverished backgrounds, and are at a greater risk of poverty and more likely to be part of the informal economy experiencing the worst. . It has a solar power generation system that serves as the power source for the electric motor which propels the wheelchair, and a control system that controls the movement and the navigation of the wheelchair. In experimenting with metal electrodes and electrolyte solutions,Becquerel discovered effect--the creation of electric ce, where solar was used to power satellites.

Alexandre Edmond Becquerel's 1839 discovery of the photovoltaic effect laid the foundation for modern solar technology. The first practical silicon solar cell was produced by Bell Labs scientists in 1954, marking a crucial milestone. With the way the cost of solar has plummeted in the past decade, it's easy to forget that going solar. . Greeks and Romans use burning mirrors to light torches for religious purposes. As early as 212 BC, the Greek scientist, Archimedes, used the reflective properties of bronze shields to focus sunlight and to set fire to wooden ships from the Roman Empire which were besieging Syracuse. Early experiments by Greeks, Romans, and Egyptians showcased the. .
