The earth's atmosphere is why light from the sun doesn't arrive as potentl y as it is outside the earth's atmosphere\, but this blockage maintains li fe on earth. Water or air would get too hot \, the temperature cycle of ea rth would die without that atmosphere. \n\n But in space\, the unfiltered solar energy makes it the standard source for most or all human craft sin ce the beginning of the human craft traveling outside earth with sputnik i n the 1900s.\n\n the Japanese will do a test of the concept\, like nuclear powered aircraft\, studies are done and based on their feasibility things will be continued. My opening question is\, how can a high energy beam no t negatively influence earth's atmosphere with the heat. \n\n Basically\, solar panels will charge a battery and the battery will emit microwaves t o earth \, because of the speed of the satellite + the lack of a more effi cient pointing apparatus on the satellite\, a set of arrays over 25 miles will be used to collect the energy. It will take several days for the batt ery to recharge. \n\n They already tested the concept on earth with a pla ne using the same solar panel + battery\, smaller in scale. Check the link s below.\n\n The first thing I notice is the lack of a focus beam. I think to make the atmosphere not manipulated they are emitting with less focus thus it needs a wide array \, geographically\, to transmit the energy. I t hink it is sensible for the earth which can't afford the atmosphere to get hotter by electromagnetic emissions. This is being sold as a green energy but I disagree. I think this will be how the moon bases or mars operation s are powered because even though electromagnetic radiation that contact t he surface of the moon or mars is less refracted or reflected than on eart h\, the electromagnetic radiation that travels across the stars is a highe r energy an undistilled variant that will always generate more energy.\n\n Contact for more information\n\n yanagawa-hiroki@jspacesystems.or.jp\n\n\ n\n  \n\n\n\n CITATIONS\n\n URL\n\n https://www.livescience.com/space/spa ce-exploration/china-plans-to-build-enormous-solar-array-in-space-and-it-c ould-collect-more-energy-in-a-year-than-all-the-oil-on-earth\n\n TEXT\n\n\ n\n China plans to build enormous solar array in space — and it could co llect more energy in a year than 'all the oil on Earth'\n\n\n\n News\n\n\n \n By Ben Turner\n\n\n\n  published January 14\, 2025\n\n\n\n China has announced plans to build a giant solar power space station\, which will b e lifted into orbit piece by piece using the nation's brand-new heavy lift rockets.\n\n\n\n Chinese scientists have announced a plan to build an eno rmous\, 0.6 mile (1 kilometer) wide solar power station in space that will beam continuous energy back to Earth via microwaves.\n\n\n\n The project\ , which will see its components lofted to a geostationary orbit above Ear th using super-heavy rockets\, has been dubbed \"another Three Gorges Dam project above the Earth.\"\n\n\n\n The Three Gorges Dam\, located in the middle of the Yangtze river in central China\, is the world's largest hyd ropower project and generates 100 billion kilowatt-hours of electricity ea ch year. According to one NASA scientist\, the dam is so large that\, if completely filled\, the mass of the water contained within would lengthe n Earth's days by 0.06 microseconds.\n\n\n\n The new project\, according t o lead scientist Long Lehao\, the chief designer of China’s Long March rockets\, would be \"as significant as moving the Three Gorges Dam to a ge ostationary orbit 36\,000km (22\,370 miles) above the Earth.\"\n\n\n\n \"T his is an incredible project to look forward to\,\" Long added during a le cture in October hosted by the Chinese Academy of Sciences (CAS)\, as repo rted by the South China Morning Post. \"The energy collected in one year would be equivalent to the total amount of oil that can be extracted from the Earth.\"\n\n\n\n Despite recent advances in the cheapness and efficien cy of solar power\, the technology still faces some fundamental limitation s — such as intermittent cloud cover and most of the atmosphere absorbin g solar radiation before it hits the ground.\n\n\n\n Scientists have prop osed a number of Space-Based Solar Power (SBSP) technologies which would c ontinuously collect and transmit energy from sunlight in space\, where it is 10 times more intense than at Earth's surface.\n\n\n\n But building an appropriately giant array would take many launches\, meaning that most pro posals failed to get off the ground.\n\n\n\n To overcome this challenge\, Long and his team are working on the development of the Long March-9 (CZ-9 ) reusable heavy-lift rocket\, which will have a lift capacity of at leas t 150 tons (136 metric tons).\n\n\n\n Besides being used for satellites\, the rocket will also be key to China's plans to reach the moon — where it wants to build an international lunar research base by 2035.\n\n\n\n China isn't the only nation eyeing plans for solar satellite arrays. The U .S. companies Lockheed Martin and Northrop Grumman\, the European Space A gency\, and Japan's JAXA space agency have also been investigating the tec hnology\, with the latter scheduling the launch of a small\, proof-of-con cept satellite this year to assess its feasibility.\n\n\n\n  \n\n\n\n UR L\n\n https://www.space.com/japan-space-based-solar-power-demonstration-20 25\n\n\n\n TEXT\n\n\n\n Japanese satellite will beam solar power to Earth in 2025\n\n\n\n News\n\n\n\n By Tereza Pultarova\n\n\n\n  published Apr il 19\, 2024\n\n\n\n Japan's upcoming space-based solar power demonstratio n will beam power to Earth next year.\n\n\n\n LONDON — Japan is on track to beam solar power from space to Earth next year\, two years after a s imilar feat was achieved by U.S. engineers. The development marks an impor tant step toward a possible space-based solar power station that could hel p wean the world off fossil fuels amid the intensifying battle against cl imate change. \n\n\n\n Speaking at the International Conference on Energy from Space\, held here this week\, Koichi Ijichi\, an adviser at the Japa nese research institute Japan Space Systems\, outlined Japan's road map to ward an orbital demonstration of a miniature space-based solar power plant that will wirelessly transmit energy from low Earth orbit to Earth.\n\n \n\n \"It will be a small satellite\, about 180 kilograms [400 pounds]\, t hat will transmit about 1 kilowatt of power from the altitude of 400 kilom eters [250 miles]\,\" Ijichi said at the conference. \n\n\n\n One kilowat t is about the amount of power needed to run a household appliance\, such as a small dishwasher\, for about an hour\, depending on its size. Therefo re\, the demonstration is nowhere near the scale required for commercial u se.\n\n\n\n The spacecraft will use a 22-square-foot (2 square meters) onb oard photovoltaic panel to charge a battery. The accumulated energy will t hen be transformed into microwaves and beamed toward a receiving antenna o n Earth. Because the spacecraft travels very fast — around 17\,400 mph (28\,000 km/h) — antenna elements will have to be spread over a distance of about 25 miles (40 km)\, spaced 3 miles (5 km) apart\, to allow enough energy to be transmitted.\n\n\n\n \"The transmission will take only a few minutes\,\" Ijichi said. \"But once the battery is empty\, it will take s everal days to recharge.\"\n\n\n\n The mission\, part of a project called OHISAMA (Japanese for \"sun\")\, is on track for launch in 2025. The resea rchers have already demonstrated wireless transmission of solar power on t he ground from a stationary source\, and they plan to conduct a transmissi on from an aircraft in December. The aircraft will be fitted with an ident ical photovoltaic panel as will be flown on the spacecraft and will beam d own power over a distance of 3 to 4 miles (5 to 7 km)\, according to Ijich i.\n\n\n\n From concept to reality \n\n\n\n Space-based solar power gener ation\, first described in 1968 by former Apollo engineer [ https://www. space.com/26175-peter-glaser-solar-power-satellite-obituary.html ]\n\n\n\ n Peter Glaser\, has been considered science fiction. Although theoretical ly feasible\, the technology has been seen as impractical and too costly\, as it requires enormous structures to be assembled in orbit to produce th e required power output. \n\n\n\n But according to the experts speaking a t the conference\, that situation has changed as a result of recent techno logical advances and the urgency to decarbonize the world's power supply t o thwart climate change.\n\n\n\n Unlike most renewable power generation te chnologies used on Earth\, including solar power and wind energy\, space-b ased solar power could be available constantly\, as it would not depend on weather and the time of the day. Currently\, nuclear power plants or ga s- and coal-fired power stations are used to cover demand when the wind st ops blowing or after sunset. Improvements in technology could help partial ly solve the problem in the future. But some pieces of the puzzle are stil l missing to secure a seamless carbon-neutral power supply by the middle o f this century as stipulated in international climate change agreements.\n \n\n\n Developments in robotic technologies\, improvements in the efficien cy of wireless power transmission and\, most importantly\, the arrival of SpaceX's giant rocket Starship could allow space-based solar power to be come a reality\, the experts said at the conference. \n\n\n\n Last year\, a satellite built by Caltech engineers as part of the Space Solar Power Demonstrator mission beamed solar power from space for the first time. T he mission\, which concluded in January\, was celebrated as a major milest one. \n\n\n\n Many more space-based solar power demonstration projects ar e in the pipeline. The technology is studied by space and research agencie s all over the world\, including the European Space Agency\, the Defense Advanced Research Projects Agency and the U.S. Air Force. Commercial compa nies and startups are also developing concepts\, harnessing the availabili ty of Starship and the emergence of advanced space robotics.\n\n\n\n How ever\, not everyone is enthusiastic about the potential of space-based sol ar power. In January\, NASA released a report questioning the feasibili ty of the technology. The difficulty and amount of energy required to buil d\, launch and assemble orbital power stations mean the energy they produc e would be too expensive — 61 cents per kilowatt-hour\, compared with as little as 5 cents per kilowatt-hour for Earth-based solar or wind energy.  \n\n\n\n In addition\, the overall carbon footprint of the power product ion and the amount of greenhouse gas emissions generated by rockets taking those assemblies into orbit make space-based solar power much less climat e-friendly than technologies used on Earth. For example\, a gigawatt-scale spaceborne solar power station\, such as the CASSIOPeiA concept plant pro posed by the U.K. firm Space Solar\, would need 68 Starships to get to spa ce. \n\n\n\n  \n\n\n\n URL\n\n https://www.jspacesystems.or.jp/en/news/4 968.html\n\n\n\n TEXT\n\n\n\n Can not copy and past.

They won't be able to afford any aspect of it.\n\n\n\n  \n\n\n\n Those who can barely afford a place to live on thi s planet need not think about hopping up off the ground &\; going to sp ace.\n\n\n\n  \n\n\n\n At best\, less than wealthy folks might be able to solar power similar to using public Wi-Fi.\n\n\n\n Expand  \n\n\n\n we w ill see\, but the history of the many oil rushes and many godl rushes and silver rushes in the usa prove that once the ability to get natural resour ces occurs\, even with machines\, wealthy people will want humans sent out there. part of the problem in outer space is energy/control systems. Firs t\, it takes time to send an electromagnetic signal. The earth has a diame ter of circa eight thousand miles. Mars is nearest earth when the earth is circa thirty six million miles away. That means four point five thousand earths are between the earth and mars in a straight line when mars is cloe st in its elliptical orbit.  that distance means a time delay on signals. The mission around the moon is complex. the moon is two hundred and thirt y nine thousand miles from the earth at times in its orbit about the earth which means thirty earths can be lined up between the earth and the moon. These distances are massive\, and since star trek or star wars technology does not exist\, current human technology has inherent weaknesses with th e distances. if a machine breaks down on the moon\, whose going to fix it? even if you have another machine\, if it has any malfunction or inability to fix the other machine\, it will not be easy to adjust it. And because of weight\, and the influence that has on gravity\, it is not easy to put a supercomputer or some modern chemical manufacturing plant in space. thes e things are very heavy. My point is \, engineering wise\, human beings wi ll be needed. The international space station will be closing in a few dec ades\, while the chinese already have their space station up there. But th ese space stations while top of the line in terms of modern tech are not f ull of amenities. the rich don't want to be in space. \n\n\n\n But i can see rich people offer chances for poor people to leave\, how was the usa b orn but the english government seeing a chance to get rid of its poor peop le. \n\n\n\n  \n\n\n\n \n\n DTSTART;VALUE=DATE:20250222 RRULE:FREQ=YEARLY;INTERVAL=1 END:VEVENT END:VCALENDAR
