Scientists envisage that in 50 years, thanks to the "solar power plant parallel to the Moon", the inhabitants of the Earth will be able to obtain extremely rich and stable solar energy, which will not only solve the problem of energy supply for future spacecraft. , but also With the continuous development and improvement of human space conversion device technology and ground receiving technology, as long as a high-power laser or microwave transmission device is built on the moon, these infinite energies can be transmitted to the earth in the form of laser beams or higher microwave beams. Then, several receiving stations are installed on the earth to restore the laser beam or microwave beam into electrical energy, and finally transmit it to each home via the electrical network.
(1) The energy allowing “Yutu” to work on the pro moonmainly comes from solar energy
Solar energy will not cause pollution to the environment when used; so it's clean energy;
There is no air on the moon and sound cannot be transmitted in a vacuum, but electromagnetic waves can propagate in the empty, so that images and data obtained by scientific detection are transmitted. to the earth through electromagnetic waves;
(2) Since there is no air on the surface of the moon, gasoline cannot burn, so the " Yutu" on the moon cannot use gasoline as a source of energy there. There is no water on the Moon, so the water turbine cannot operate. It can only use solar cells to provide electrical energy and use electric motors to operate.
So the answer is: (1) Solar energy; electromagnetic waves;
