In space, there are no cycles of day and night or clouds, making it the perfect place for 24-hour solar energy generation. But how do get the electricity down to earth? Scientists of the Japan Aerospace Exploration Agency (Jaxa) have succeeded in transmitting electricity through microwaves. They sent 1.8 kilowatts—enough to power an electric kettle—170 feet (about 50 meters) through the air. The beam was transmitted with a great degree of accuracy, showing the technique may be used on a larger scale. It’s a—small—step towards the goal of delivering solar power from space but at the same time it shows the endless opportunities for clean, renewable energy.
Scientists transmit wireless power; clean energy from space step closer
