Countries with important studies on space Japanwill try to transmit solar energy obtained in space to Earth in 2025.
Japan will not break new ground in this regard. Because last year, the California Institute of Technology announced that they had achieved a very important success. Scientists stated that they have turned a plan that has been on the table since 1968 into reality for the first time. Smooth and wireless transmission to Earth via solar energy collected in space had accomplished. Within the scope of this success achieved in an experimental project, a group of researchers from Caltech developed the “Solar Power Demonstrator (SSPD-1)” center in low earth orbit.MAPLE” collected solar energy, converted it into electricity, and sent it to microwave receivers placed on a rooftop on Caltech’s Pasadena campus. In short, the electricity produced in space came to Earth in a usable form. Ali Hajimiri, co-director of Caltech’s Space Solar Power Project (SSPP), said, “To our knowledge, no one has ever demonstrated wireless energy transfer from space before, even using fairly expensive stable/fixed structures. We did this with our own integrated circuits using flexible and lightweight structures. This is a first” he said.

Japan has also been working on this issue, and the country has been working on transferring solar energy from space to Earth for many years. wants. To make this a reality “2025” Stating that they will take the first concrete step in 2019, scientists will send a small satellite weighing 180 kg to low earth orbit and will try to transmit approximately 1 kilowatt of power from an altitude of 400 kilometers. Reportedly, this spacecraft will include a 22 square meter photovoltaic panel to charge the battery. So why space? After all, we can produce energy, that is, electricity, from the sun on Earth. As far as reported, solar panels in orbit are a potentially unlimited source of renewable energy. In space, solar panels can collect energy regardless of the time (There is no natural production at night on Earth) and the method of sending the generated energy (microwave basedThey do not have a cloud barrier regarding ). Solar power plants on Earth experience huge production losses on cloudy days, this does not exist in space.
