A U.K. start-up says its power-beaming technology could provide the cheap, reliable energy source the Earth needs by harvesting solar power in space, 24 hours a day.

Belfast

A U.K. start-up is proposing an innovative approach to meet global energy demands by harnessing solar power in space, which could potentially provide a constant energy source. The premise is built on utilizing power-beaming technology to capture solar power in space, where solar panels can receive sunlight around the clock, unlike on Earth where sunlight availability varies. The start-up suggests that this method could offer a reliable and cost-effective solution to energy needs.

The technology aims to overcome the limitations faced by terrestrial solar energy systems, which are restricted by the day-night cycle and weather conditions affecting solar panel efficiency. By positioning solar panels in space, the start-up envisions a system that can generate power continuously and transmit it back to Earth. This approach to energy generation presents an opportunity to access an untapped and essentially infinite power source, potentially revolutionizing how the world accesses and uses energy.



Solar panels in space could send power to Earth 24/7

A UK start-up says it's figured out a way to generate cheap and reliable energy 24 hours a day throughout the year. The concept requires solar panels like those used on Earth, but in orbit. They would harvest sunlight, turn it into electricity, convert that into microwaves, and then beam it to a station connected to the local grid. The company is called Space Solar. Martin Soltow is its co-founder. It's an incredibly capable future clean energy technology, and this is about very large satellites high above the Earth harvesting the abundant solar energy, converting that to microwaves and beaming it to Earth. And in this way, we can get gigawatt-scale continuous power day and night and through all seasons and weather, and this is what we need for our future clean energy mix. This small-scale demonstration is called Harrier. The company says it shows the ability to steer a microwave beam from a geostationary satellite. As it revolves, it is continually pointing at the sun, as it will have to do in space, as well as the beam's target on Earth. Harrier is doing two things. It's demonstrating for the very first time the ability to steer a microwave beam right through 360 degrees and with a continuous, reliable beam. And secondly, it's demonstrating the control of the system. The space-based solar power concept is called Cassiopeia. Soltow says the novel technology has no moving parts, which removes a major source of weight and cost. The cost of these systems in terms of the cost of the electricity they could produce could be very comparable to wind and solar now, and substantially less than nuclear. And the reason for that is that they provide huge yield. If you put a solar panel into space, it generates about 13 times the amount of energy that that same panel does on Earth, and this really underpins the good economics of space-based solar power.

The US State Department accused Russia of having used a chemical weapon against Ukrainian forces in violation of the Chemical Weapons Convention, while also announcing fresh sanctions against Moscow. In addition to the chemical agent chloropicrin, Russia also used "riot control agents (tear gas) as a method of warfare in Ukraine, also in violation of the CWC," the department said in a factsheet.
