Alternative Energy Sources
Alternative Energy forms
Some of these resources are very widely known and used, such as Petrol, diesel, biomass, Wind energy, Geothermal energy, Tidal energy, etc.... are widely known.
We also know a source of energy called solar energy, which is obtained from the light rays from the cells. This project talks about Solar wind energy which is a stream of energized, charged particles flowing away from the sun.
What is Solar Wind?
There's a fascinating spot some 932,000 miles away from Earth where the gravity between the sun and Earth is perfectly balanced. This spot captures the attention of orbital engineers because a satellite can orbit this spot, called Lagrange 1 just as they can orbit a planet. But the spot tantalizes scientists as well: Lagrange 1 lies outside Earth's magnetic environment, a perfect place to measure the constant stream of particles from the sun, known as the solar wind, as they pass by.
Solar wind as mentioned above is a stream of energized and charged particles flowing away from the sun.
Scientists believe that a satellite orbiting the earth at the same distance that the earth orbits the sun can capture these energized particles and use the energy from these particles to generate electricity or any other forms of energy.
What technology is being used to harness this energy source?
Two of the instruments were built at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and one at the Massachusetts Institute of Technology and the Harvard-Smithsonian Center for Astrophysics, both in Cambridge, Massachusetts.
How can we get access to this form of energy?
The video above shows that the solar wind particles form an orbit like circle around the earths atmosphere. To extract this energy, satellites situated near the atmosphere of the earth which are at an equal distance away from the earth as the earth is from the sun. This will help the satellites capture the charged particles and hence harness this energy.
How reliable is this energy source?
As of now this is just an idea that has not been completely enacted. This idea is soon to come to life, and NASA will be a big part of it.
