The concept of harvesting solar energy through satellites that are power-beaming has been gaining attention in recent times. For decades that reflection has been fomented but now worldwide garnering new looks. Experts in Japan, technologists in China and the U.S., and researchers in the U.K. Space Agency and European Space Agency are all working to make space-based solar power a reality.
In 1968, the notion of a solar power satellite was detailed and patented by U.S. space pioneer Peter Glaser. The method to collect energy using solar cells from the sun and then sending energetic muscles of microwaves to receive antennas on Earth. Then electric energy could be formed by converting those microwaves and then supplied to the power grid. At the Goldstone Deep Space Communications Complex in California, a facility of NASA’s JPL, in the mid-1970s, microwave power transmission experiments in the tens of kilowatts were successfully conducted.
Researchers over the past decade have worked hard and made a lot of advances that increase the chance of space solar power realizing in the next decade. The reshaping of the landscape of 21st-century space activities is happening because of the increasing unfolding value of New Space. In learning SSP, two of the biggest hurdles have always been the cost of hardware and the launch. The economics of SSP concepts have been more viable within the next decade. There will be advances in the growth in various component technologies, maintenance and servicing systems, progress in robotics for space assembly, and advances in space launch capabilities.
The world needs and replacement of oil and natural gas, the two primary sources of energy. In 2100, many experts say about 20% of electrical power comes from terrestrial nuclear and renewables, with 80% supplied by Astro-electricity. This century, the control of space solar power platforms will dominate outer space activities. Later this century, if SPP becomes a reality, the U.S. military will have to defend and protect these new sources of national energy security.
SSP concepts are developed by some people that would be launched from the Earth and autonomously assembled in geostationary Earth orbit, but experts don’t see it as a successful proposition. According to experts, substantial space industrialization efforts are needed to build the thousands of SSP platforms and involve more than a million people in space by the end of the century. Infrastructure operating throughout the Earth-moon system the starting point will be establishing the enabling astrologists. Those high astrologists require a high-priority U.S. Air Force, not a space force.
Already there is a space technology underway. The Photovoltaic Radio-frequency Antenna, Module Flight Experiment, is being carried by the Space Force’s robotic X -37B spaceplane. This is a Naval Research Laboratory investigation into transforming solar power into radio-frequency microwave energy. It was launched in May 2020. The focus of this investigation is to appraise the performance of sunlight-to-microwave conversation. The big strike against space solar power has made economics work. The chances that it will perform are more because of the cost reduction of space access and mass production of space hardware.
