  • Space bosses are to investigate whether electricity could be beamed wirelessly from space into millions of homes.

    The European Space Agency will this week likely approve a three-year study to see if having huge solar farms in space could work and be cost effective.

    The eventual aim is to have giant satellites in orbit, each able to generate the same amount of electricity as a power station.

    ESA's governing council is to consider the idea at its Paris HQ on Tuesday.

    Wonderful! I wonder if we could see this from Earth, I don’t expect to unless it’s really big. And even if we did what would it look like?

    This is why we should pay attention to space, cause there is a whole lot of stuff we CAN do for a good price.

    So our world does not suffer.

    this is gonna give the conspiracists fuel for “jewish space lasers” 😂

    This will work better in places with little or no atmospheres like the Moon and Mars.

    or a Jo Brand show

    We are getting closer to a Dyson’s sphere day by day.

    as we should be

    Not before the next big step, space mining.

    L KS says:

    Yes indeed, microwaves beaming from space to a targeted area. What could possibly go wrong !

    Sam says:

    Walk out the house, what could possibly go wrong!

    Justin Brach says:

    Yeah exactly….

    VeeTee says:

    You mean this could be used as a weapon of immense power by whoever controls it? Wow, now I’m starting to believe those solar farms will actually be built.

    RAI FIKAR J says:

    @Jamm hmm the solar panel was in up there in the space tho and it blocked the sunlight to generate the power that will be microwaved. So it was not heating the planet just shift the energy and concentrate it. Assuming if somehow we covered 1/3 of earth (space area is big) it will disrupt climate and make wild temperature swing but the earth will cooler but the area around the energy beamed will extremely hot

    Space lasers. Made by…

    One of the best news I have heard this year 🙂 I only hope the earth collector is sea based and not land based, perhaps having the collector span the equator for constant collecting and then each country can then suck off the equator collector like plugging your device into the house wall. if it doesn’t work if each country has its own SpaceX type rocket it could always go up each day and collect the energy from the solar array in space but im sure the fuel to get there and back still might not be worth it lol

    Jason Purkiss says:

    @Forty Two lol what part did you not like?

    Forty Two says:

    @Jason Purkiss a collector that spans the equator??? did you smoke any white stuff today?

    Jason Purkiss says:

    @Forty Two unfortunately i cant smoke as it gives me whites and panic attacks 🙁 but what’s worse a collector that spans the equator constantly collecting energy away from human population or a high energy beam pointed near to your city that everyday has to calculate the times to turn on and off without wiping out 25% of a country 🙂 for me it #just reduces the risk and makes it simple

    Drakey Fenix says:

    @Jason Purkiss It sound interesting, but building something so massive that it spans the entire globe would require all governments in the world to work together and settle on paying for it, which would be unlikely. Having a rocket go up and down to collect energy and distribute it would be very inefficient as current battery technology is extremely inefficient and can’t store sufficient amounts of energy to power a significant number of consumers. Not to mention the pollution from rockets constantly going up and down, kind of defeating the purpose of using renewable energy like solar.

    Jason Purkiss says:

    @Drakey Fenix I do agree with you about the rocket, was just throwing the idea out there for fun 🙂 but we are all human we should work together and we can just look at the internet it expanse the globe and we worked together to make it work we could also run the internet lines along the energy collecting equator

    D M says:

    Mind-blowing… We could of course spend like $1bn to put super efficient solar panels on every high-energy generating roof, but why should we solve the problem? Let’s instead spend $100bn to microwave the planet and solve 1 problem by creating 5 bigger ones! Hurray!

    Luc Verhaegen says:

    Principally correct, but…

    1B EUR buys just 1GW of solar btw. Same for onshore wind. 333MW of offshore wind. 200MW of biogas. And just 100MW of nuclear.

    D M says:

    ​@Luc Verhaegen Thanks for your comment. Not sure whats the point you are making tho.

    Luc Verhaegen says:

    @D M Just trying to give you a perspective of what these things actually cost 🙂

    Also, solar (in germany) has a capacity factor of 11.5%, onshore wind 25-30%, offshore wind 50-60%. Biogas is probably 90%, but depending on whether biogas is burned directly, or biomethane is being created and burned in more efficient peaker plants, the electrical efficiency is 35%, or 50+%. Nuclear has a theoretical maximum capacity factor of 90% (18months run time, then 2 months reloading and reshuffling of fuel rods), but the reality is much closer to 70% (france 2021 – 2022 will be much much worse).

    Also, Tesla megapacks cost 500usd per kWh (2021 figures, 1.6M for 3.2MWh of expensive NMC cells). You can get LiFePO4 cells with about a kWh of capacity, delivered to germany with customs for 120EUR. So in 1-2ys time grid level lifepo4 based storage could cost about 100eur per kWh.

    So now you have the facts and tools to divvy up that theoretical 100B EUR/USD/GBP, and you can put any pie-in-the-sky energy project in relationship to what it would cost to actually use renewables instead.

    A healthy mix of renewables, after including the respective capacity factors, deliver twice the real world electricity of nuclear. And the quoted 10k EUR for 1kW of nuclear generation capacity is just the construction cost.

    David Sigbi says:

    A lot of people in this comment section need to revise light waves and frequencies. If all microwaves were like microwave ovens we’d all be dead already. This would be similar to wireless chargers just much more powerful.

    C C says:

    If the scientists can make it viable, it will be a marvelous achievement because we will be able to reduce fossil fuel production tremendously

    Xiaojing Xu says:

    Fantastic idea!

    Shaun Dubai says:

    Question – won’t this heat the planet? Night time, the planet loses heat?

    m b says:

    If all the engineering effort and money was directed towards new drilling technology you could drill down to a limitless source of heat to generate steam to run existing turbines. With the right drilling tech, geothermal heat is available anywhere in the world and no need to irradiate the land, animals, birds or people with microwaves. Some people complain about the radiation from mobile phone towers; just wait until they find out the power these space-based systems will produce.

    madcow 3417 says:

    With such huge efficiency losses, why not just use cheap mirrors to redirect sunlight? Personally I’m voting for improved and increased energy storage, such as thermal batteries or flow batteries.

    BORCLO says:

    I wanna live thousands of years for this.

    Mats Boswijk says:

    I wonder about what all this extra energy being send down to earth will do for our world? Of course we need future proof ways to produce energy, but in my mind the key lies more in using less of it in general. That is where we can gain the most. Use less energy; industry, transport, production, at home, et cetera. Regardless, this is a very interesting project.

    Da Starchild𓂀𓋹 says:

    Could solar panels be generating electricity via the heat? is it gaining/accepting electrons out of heat ?

    Atlas says:

    I studied this back in college. I know it sounds crazy but the science works out.
