Is solar energy used as power in space flight Solar panels collect solar energy and convert it into electric energy. Is electric energy converted into kinetic energy? It seems that the motor I think of can't provide power in vacuum. What can I do? Can I only rely on the fuel I carry? Let's not talk about the solar sail. I know that
Electricity can provide power
Plasma electric rocket. This is not new. The European lunar exploration satellite has used this power for a long time. It uses electric field to accelerate plasma to provide kinetic energy
Usually, the power generated by the photocell on the satellite is not used to provide power, but to provide power for the electronic equipment on the satellite. The power of these satellites still depends on the conventional chemical rockets. The role of the Rockets is to change the orbit and maintain the orbit height. Once the fuel is used up, the satellite will soon be abandoned
What is secondary energy besides electricity?
For example, the more the better~
Secondary energy
Secondary energy refers to the energy obtained from the processing and conversion of primary energy, including electric energy, gasoline, diesel oil, liquefied petroleum gas, hydrogen energy, etc, At present, gasoline and diesel are the most widely used combined energy sources. Secondary energy can also be interpreted as the energy re used from the primary energy sources. For example, the steam generated by burning coal can drive the generator, and the electric energy generated can be called secondary energy. Or after the electric energy is used, it can be converted into wind energy through the electric fan. At this time, wind energy can also be called secondary energy, There must be a certain degree of loss between secondary energy and primary energy
What else is the energy we use related to solar energy
Generally speaking, all the fossil fuel energy on the earth comes from solar energy, such as oil, natural gas, coal, etc. because they are the remains of animals and plants buried in the strata, formed after at least a million years, and they all come from the energy of the sun
What kind of energy do we use that has something to do with solar energy?
Coal, oil, natural gas, wind energy, tidal energy, biomass energy, solar energy, etc
