Space-based Solar Power: Endless Sunshine to a Fried Earth

In recent years, space agencies from all over the world have launched studies looking at the feasibility of constructing orbiting solar power plants. Such projects would be challenging to pull off, but as the world’s attempts to curb climate change continue to fail, such moonshot endeavors may become necessary.

Solar power plants in space, exposed to constant sunshine with no clouds or air limiting the efficiency of their photovoltaic arrays, could have a place in this future emissions-free infrastructure. But these structures, beaming energy to Earth in the form of microwaves, would be quite difficult to build and maintain…

A space solar power plant would have to be much larger than anything flown in space before. The orbiting solar power plant will have to be enormous, and not just to collect enough sunlight to make itself worthwhile. The main driver for the enormous size is not the amount of power but the need to focus the microwaves that will carry the energy through Earth’s atmosphere into a reasonably sized beam that could be received on the ground by a reasonably sized rectenna. These focusing antenna would have to be 1 mile (1.6 kilometers) or more wide, simply because of the “physics you are dealing with. Compare this with the International Space Station, at 357 feet (108 meters) long the largest space structure constructed in orbit to date…

In every case, building a space-based solar power plant would require hundreds of rocket launches (which would pollute the atmosphere depending on what type of rocket would be used), and advanced robotics systems capable of putting all the constituent modules together in space. This robotic construction is probably the biggest stumbling block to making this science fiction vision a reality.

Converting electricity into microwaves and back is currently awfully inefficient
Airbus, which recently conducted a small-scale demonstration converting electricity generated by photovoltaic panels into microwaves and beaming it wirelessly to a receiving station across a 118-foot (36 m) distance, says that one of the biggest obstacles for feasible space-based solar power is the efficiency of the conversion process… Some worry that microwave beams in space could be turned into weapons of mass destruction and used by evil actors to fry humans on the ground with invisible radiation.

The vast orbiting structure of flat interweaving photovoltaic panels would be constantly battered by micrometeorites, running a risk of not only sustaining substantial damage during operations, but also of generating huge amounts of space debris in the process. For the lifecycle of the station, you have to design it in a way that it can be maintained and repaired continuously…

And what about the whole thing once it reaches the end of its life, perhaps after a few decades of power generation?  It is assumed that, by the time we may have space-based solar power plants, we are most likely going to see quite a bit of permanent infrastructure on the moon. Space tugs that don’t exist yet could then move the aged plant to the moon, where its materials could be recycled and repurposed for another use…We could also have some kind of recycling center on the moon to process some of the material..

How to Microwave People

An international studies professor in Beijing has claimed China used microwave weapons against Indian soldiers during a standoff along the disputed Himalayan border. Jin Canrong, professor of international relations at Renmin University, told his students Chinese forces forced the Indian soldiers to retreat by turning “the mountain tops into a microwave oven”, according to The Times. Microwave weapons work much the same as regular microwaves. The device heats the water in the human target’s skin, causing immense pain and nausea. The weapon is meant to incapacitate enemies through severe pain but isn’t meant to cause lasting damage. Professor Jin claimed the weapon worked “beautifully” on the Indian soldiers, without violating the “no gunfire” agreement between the parties.

“In 15 minutes, those occupying the hilltops all began to vomit,”reportedly told his students during a lecture. “They couldn’t stand up, so they fled. This was how we retook the ground.” Professor Jin said the reason China didn’t publicize the event was because it was so successful, adding that India also kept the incident under wraps because “they lost so miserably”..

Similar microwave technology aimed at incapacitating but not killing targets have been developed by other militaries. The US used the same technology to develop the Active Denial System, which was designed to be used for area denial, perimeter security and crowd control…Recently, Russia was accused of using its own secret microwave weapon to attack two CIA agents in Australia. It comes after American officials in Cuba fell in with what was dubbed “Havana Syndrome”, with victims often hearing strange sounds, before becoming dizzy, suffering headaches, experiencing memory loss and hearing loss.

The Havana/China Syndrome: Who Used Directed-Energy Weapons on US Diplomats?

 In December 2020,  U.S. scientific panel has concluded that exposure to a type of directed energy was the most likely culprit for a number of medical symptoms, including dizziness and memory loss, experienced by diplomats posted in Cuba and China. In a new assessment published on December 5, 2020  by the National Academies of Sciences, Engineering, and Medicine, scientists identified “directed, pulsed radio frequency (RF) energy” as the most likely explanation for a series of symptoms experienced by diplomats posted at U.S. facilities—a broad category of energy that can include microwave radiation.

The scientists concluded that the symptoms experienced by a number of U.S. and Canadian diplomats, which included dizziness, headache, fatigue, nausea, anxiety, cognitive difficulties and memory loss, were “unlike any disorder in the neurological or general medical literature.”… Governments, including the former Soviet Union and the U.S., have tested using directed energy as a potential weapon or a tool for espionage or crowd control in the past.
