Zuckerberg's Meta will beam sunlight from space to power AI data centers, solar-collecting satellites will orbit 22,000 miles above Earth — firm reserves 1 Gigawatt of orbital solar energy and 100 Gigawatt-hours of long-duration storage

Meta announced in a press release on Monday that it had begun plans to power its AI data centers with sunlight beamed from space. The company plans to place solar-collecting satellites in geosynchronous orbit roughly 22,000 miles above Earth to beam the sunlight to collectors on the Earth's surface. The plan is part of two new partnerships aimed at solving the rising energy demands of the company’s rapidly expanding AI infrastructure.

The company said it has reserved up to 1 Gigawatt of capacity from space solar startup Overview Energy, alongside another deal with energy storage firm Noon Energy for up to 1 GW / 100 Ggigawatt-hour of ultra-long-duration energy storage.

    The environmental impact of a, what will be in essence, "death beam" will surely be interesting to debate. Including Air Traffic around the area!

    Even if it'll be "low intensity", it'll still need a proper study around harms to the areas and risks. Also, low energy beams would require a lot of space so you make up for the low energy density.

    Interesting thought process, for sure.

    Regards.

    Meta has way too much money when they give it to companies that have some idea that has been around for years that nobody has figure out how to actually implement. They would have to have systems already being assembled to even think about having anything in orbit in 2 years. The time to get a slot from one the rocket launch companies is more than that. Almost seem like meta is being scammed. One of these companies meta is giving money to has not even existed for 4 years it is unlikely they have anything more than design ideas. It takes a very long time and lots of money to get even prototype boards from manufactures and they need stuff that can survive being launched into space.

    Doesn't that solar energy end up adding more heat to the earth whatever energy it is ultimately converted to?

    Those satellites would harvest solar energy in space and beam it down to Earth-based solar farms using low-intensity near-infrared light.
    I remember China wanted to do it with microwaves: https://sustainabilitymag.com/articles/chinas-1km-solar-array-the-manhattan-project-of-energy

    It should be the same with nuclear fission/fusion, etc. If we started producing say 10,000x the energy that we use today, Earth wouldn't be able to radiate it away fast enough and we would cook.

    The global electricity production should be at least 20 TW (20,000 GW), so another 1 GW or 30 GW isn't going to have a significant effect.

    Space based solar doesn't produce greenhouse gases beyond construction and the rockets deploying the panels (maybe significant?). So it may be better than hydrocarbon sources.

    The real question: can it be cheap? Maybe if launch costs fall.

    Wasn't this a type of power plant in one of the early Simcity games? Occasionally the beam would miss the collector and start fires so you had to keep open space around it.

    Isn't sunlight beamed down to Earth without any human involvement? Wouldn't the gain from solar collection in space be offset by the loss from beaming it through the atmosphere? It just seems that solar panels on Earth would be about as efficient once you factor everything. Not to mention the much higher cost and energy used to put solar collectors in space. This just doesn't seem financially or technically viable.

    I think the idea is that the beam can work on the dark/night side of the planet if the solar reflector is at the right angle. This way it's a 24x7 supply.
    I am very skeptical that it would be worth it, but maybe the people paying for the experiment believe otherwise.

    just make it stop.
    i just hate every body remotely involved in tech now.

    Zuckerburg and the cohort of billionaires (Now we get to add Kevin O'Leary to the growing lists) are so anxious to convert our planet into Mordor.

    The Soviets did the space mirror beam down to earth thing in the 90's.
    The prototype worked, but the followup failed to deploy.

    While lithium-ion battery systems are effective for short-duration storage, they are generally not designed for sustained power delivery over multiple days.
    But where are they building a data center that you have to run on battery power for days?
