There is a better way to feed the planet, a way that doesn't get the attention it deserves. The Caltech electrical engineering professor imagines thousands of solar panels floating in space, unhindered by clouds and unhindered by day-night cycles, wirelessly transmitting massive amounts of energy to receivers on Earth. This year, that vision came closer to reality when Hajimiri, along with a team of Caltech researchers, demonstrated that wireless power transfer in space was possible: solar panels they had attached to a Caltech prototype in space They successfully converted electricity into microwaves and transmitted it. those microwaves to receivers about a foot away, lighting two LEDs. The prototype also transmitted a small but detectable amount of energy to a receiver on top of its laboratory building in Pasadena, California. The demonstration marks a first step in wirelessly transferring usable energy from space to Earth, an energy source that believes will be safer than the sun's direct rays.
The lightning intensity must be kept below the solar intensity on Earth," he said. Finding alternative energy sources is one of the topics business, scientific and public policy leaders will discuss Pakistan Phone Number during the News' Climate Forward event on Thursday. The Caltech demonstration was a significant moment in the pursuit of space-based solar power, a clean energy technology that has long been overshadowed by other far-reaching clean energy ideas, such as nuclear fusion and clean hydrogen. Low cost. If space-based solar power can be made to work on a commercial scale, said Nikolai Joseph, senior technology analyst at NASA's Goddard Space Flight Center, such stations could contribute up to 10 percent of global energy by The idea of space-based solar energy has been around at least since 1941, when science fiction writer Isaac Asimov set one of his short stories, “Reason,” in a solar station that radiated energy via microwaves to Earth and other planets. In the 1970s, when a five-fold increase in oil prices sparked interest in alternative energy, NASA and the Department of Energy conducted the first significant study on the topic.
Under the direction of physicist. Mankins, NASA took another look and concluded that investments in space launch technology were needed to reduce the cost before space-based solar power could become a reality. “There was never a question that it was technically feasible,” said Mankins, now president of Artemis Innovation Management Solutions, a technology consulting group. "The cost was too prohibitive." Today, however, the calculus may be changing. The arrival of Elon Musk's SpaceX has brought a sharp drop in the cost of rocket launches. From 1970 to 2000, the average cost of launching a rocket into low Earth orbit was about $18,500 per kilogram, or 2.2 pounds, of weight; Today, the cost has plummeted to just $1,500 per kilogram. That reduction has helped slash estimates for building power plants beyond Earth's atmosphere. A 1980 NASA review concluded that the first gigawatt of space solar power (enough energy to power 100 million LED light bulbs) would cost more.
