Since the 1960s, space enthusiasts and international space agencies have had one dream: to collect solar power and use it on earth. What seemed utopic more than 40 years ago is about to become reality: the Japanese Aerospace Exploration Agency JAXA especially is hell-bent on harvesting solar energy from space by 2030.
Researchers from the Japan Aerospace Exploration Agency (JAXA) managed to transfer 1.8 kilowatts of power via microwaves to a specific receiver located at a distance of 170 feet (55 meters). You may think that it’s not such an impressive distance, and the delivered energy was only enough to power an electric kettle, but the experiment opens up new prospects for alternative energy research. In particular, similar technology could be utilized for collecting solar energy in space and delivering it to Earth. In fact, this is how the International Space Station is powered – it converts sunlight into electric current with the help of solar cells placed on its solar array wings.
The Japanese Science and Economy and Trade Ministry are currently pushing the project, set to launch in 2030. Just last month they put together the Institute for Unmanned Space Experiment Free Flyer (USEF) consortium consisting of several high-tech giants such as Mitsubishi Electric, NEC, Fujitsu and Sharp. Given that Japan has few energy resources of its own and therefore relies heavily on oil imports, it is no surprise that the country has long been a leader when it comes to solar and other renewable energies.
It seems that after more than a century, someone eventually managed to come close to Nikola Tesla’s breakthrough in transferring wireless electric power. Japanese scientists for the first time succeeded in transmitting electricity wirelessly through the air.
In any case, I strongly believe that the world community will soon realize that alternative sources of energy are the only way for humanity to survive. While definitely different than Tesla’s idea of FREE energy, if the SSPS is finally implemented, we would have a permanent supply of wireless electric power regardless of the time of the day and the weather conditions.
