Satellites made by humans have long been able to harness the sun's energy as it washes over them outside the shield of Earth’s atmosphere. But what if we could just beam all that solar energy directly down to Earth? This science fictional notion may be a reality sooner than you think. That's because Japanese researchers have just made a serious breakthrough in wireless energy transmission. According to Phys.Org, Japanese scientists have used microwaves to transport 1.8 kilowatts of power through the air to a receiver 170 feet away. While the distance is not so huge, this accomplishment is being hailed as a serious phase toward the development of space-based solar energy collectors that beam energy back to Earth's surface. The Japan Aerospace Exploration Agency (JAXA) has been operational on the problem of space-based solar powered collectors for many past years. JAXA hopes to one day seal the sky with solar farms that can soak up solar energy, regardless of the weather situations, and beam back to us in the form of microwave radiation.
One thing to remember here is that we're still years out from such equipment existing, but if we're ever going to completely decrease our dependence on fossil fuels, doubling down on the sun is possibly one of the finest options we've got.
