In the recent years, Japan had been crippled with disasters such as the Great Tohoku earthquake and nuclear meltdown in Fukushima. Now, the Japanese Aerospace Exploration Agency (JAXA) had come up with a solution to practically remove dependency on nuclear power by creating orbital solar farms. And no, it didn't mean that Japan will turn into an entire solar panel - instead, these solar farms will be built and remain in space!
The proposal, which was reported earlier by IEEE Spectrum, states that these solar farms will rotate in a geosynchronous orbit so it could collect energy directly from the sun. The collected energy then will be transmitted to substations here in Earth via microwaves, which will then be converted into DC power. This could be a great plan to source natural energy; however, the government must have to prepare a really mean amount of budget to fund this promising project.
If this plan will push through, these solar farms are projected to be finished by the year 2030. But as there is already a problem on how and where to get funds for space mission projects, it's a sad thing to hear that this proposal is not feasible as of now. For the meantime, like the possibility of making life-size gundam robots, this solar project will remain a science fiction.
