    I had also think about this type of power plant .But my idea was sending the power by wireless system.Wireless system is used in charging mobile and we can also use it in space ! Isn’t it??

    1000 times more expensive 🙂

    Won’t there be any potential life or other types of hazards while beaming back the microwave reductions or the laser beams?

  5. Arthi Sanjeevi on September 14, 2020 at 3:45 pm

    wont the earths rotation mess with how this system works

  6. Iznaga1420 on September 14, 2020 at 3:48 pm

    This is a horrific security liability. Any country with sufficient rocketry technology can knock out these things, thus holding hostage any place dependent on them for energy. The military will likely have to invest many billions of dollars into a project like this as well as the tech needed to defend them from potential attackers.
    But… what if we could put this stuff on the moon out of reach of the capability of most militaries?

    very uneducational :<

  8. waht mmm on September 14, 2020 at 3:50 pm

    how fast does this thing have to move at that far away distance?

  9. 666 on September 14, 2020 at 3:51 pm

    It’s A very effective weapon indeed maybe someday memories will return but for now, let’s hope it was only a bad dream 🙂

  10. Robbert Lucassen on September 14, 2020 at 3:51 pm

    It is probably a laser weapon, but i would ask Philips (CD) to built the lasers because it would take a lot-of tracking and adjusting for it to focus it’s beam. It’s a concept, i understand. We would be better of putting the resources in play to develop new solar materials with higher efficiency to be used on earth. In line of this concept i don’t understand why we think of large array’s of solar flat-panels ? You can not adjust the orbit of these satellites, it would take enormous reserves of (gas) energy on the satellites themselves. Therefore inflating a balloon the size of a soccer field is easier to do in absolute vacuum of space. The balloon material should be able to transform the heat through heat exchanges and store that in (a motor) momentum (Rotating Flywheel). The balloon will of-course rotate counter clockwise and the other side of it will be exposed to the sun etc. etc. Because we can’t suck the energy out (Through a Laser beam) the balloon will go ballistic and be destroyed by centrifugal forces. End of experiment.

    Does the Moon have more Helium-3 or Thorium?

  12. John Adan on September 14, 2020 at 3:52 pm

    Should be hard the maintenance 🤔 if it fails can be a big problem 🤔 I still believe that those alternatives aren’t the best, is a good idea 💡 definitely but I would choose more the geothermal than this , both are really hard to build…… but for Mars colonization is a plus I believe 👍

  13. IDNeon357 on September 14, 2020 at 3:53 pm

    Why are smart people so stupid. How do you get from A to Z? Through the alphabet.

    You’ll never get a space based power generation off the ground.

    But using fly wheel storage this system can be used to transfer large capacity of energy across the globe. There you fycking idiots.

    Just revolutionized your world

    Love Planet Earth and be an Eco Hero! 🌍❤️

  15. Anshuman Arun on September 14, 2020 at 4:00 pm

    While this technology would benefit the humanity, oil and gas lobby won’t allow this to happen.

  16. douglas howard on September 14, 2020 at 4:03 pm

    there is no scarcity on earth !! none, at least not natural.

  17. Philip Andrew on September 14, 2020 at 4:03 pm

    One complication that I see with such a solar system in GEO orbit is that the momentum of light will constantly push the array out of its GEO orbit and the array will constantly have to make solar sail adjustments to its orbit. This may effect its overall performance.

  18. Barney Fife on September 14, 2020 at 4:03 pm

    Only delayed by the ‘power’ of the oil interests

    satelite with big laser canon trageting the Earth? Give me two!

  21. LEE WONNELL on September 14, 2020 at 4:06 pm

    This would also be a good thing from Mars and the Moon

  22. Andrew Gordon on September 14, 2020 at 4:07 pm

    These could be repurposed to power Particle Beam Weapons with practically unlimited power.

  23. Jose Juan Rivera Reyes on September 14, 2020 at 4:09 pm

    Reminds me of SimCity 2000 and its Microwave power plant 🙂

  24. LoneStarWolf Entertainment on September 14, 2020 at 4:14 pm

    The problem with putting the Solar Panel in a Geostationary Orbit is the earth’s rotation would eventually face away from the sun in the form of nighttime, this problem however can be fixed by having multiple Geostationary Solar Panels so that one (or more) is always facing the sun and producing energy.

    Is this what is burning up California?

  27. Archer V. on September 14, 2020 at 4:16 pm

    LOL. is the most stupid idea on the earth!

  28. Slartibartfas042 on September 14, 2020 at 4:17 pm

    Yeah. Space will rule out all of our (mental?) problems we have on earth. There is not even nearly 10 percent of the easy usable energy used that we already *do* have on earth. Now we are planning to use an extremely risky and complex technical solution to transport additional energy with extremely high-energy-beams down to earth to use this as additional energy form?
    Economical (/mental?) aspect: Looking outside I can not even see 2 house roofs with an solar panel (either solar collector or solar panel) mounted on it. There is plenty of room left to install panels directly on our facilities *without* having any further effect on usable room. Another form of using already existing energy, in that case heat, would be usage of heat pumps. How many heat pumps do you know being located in your neighbourhood? How many zero-energy-houses do you know nearby? Technology for it exists since more than just a decade. And finally, why are our governments all aiming to some energy delivery companies that do get subventions to build up some facility but support to the local people get’s cut more and more? Why are we not even using that capacity that is already delivered for free directly to our roofs and environment? Could there be possibly some financial intersts and lobby behind?
    Ecological aspect: From climate aspect – all energy, regardless if it is fossile energy or energy we redirect from space to the earth, is *additional* energy that is converted on earth. And by converted I mean this energy will be converted into local *heat*. Even electricity will be converted into heat – think only of your computer, your TV-set, your phone charger getting warm, your electrical car having to control and maybe even cool down the batteries in both cases, for charging and driving… Having said this – what’s the point of "saving the climate by using solar power" if we even concentrate *more* solar power by adding solar power from the space to heating up our environment on earth?
    Will it be safe?: From security/safety reasons – I am not even thinking of *intentionally* using that energy beam as a weapon. But sometimes things go horribly wrong in space, when collisions with meteorites or space junk do happen. How do we guarantee that such a collision won’t turn the space facility to direct it’s beam directly to our cities? And we are honestly expecting that high-power-beams being safe technology?
    And with all of above we did not even think of how to distribute all that big power to where we really need it, the losses from transportation, the amount of resources we will have to use for transportation and so on.
    Looking at all of this questions one may ask: What is the real purpose of this space located power concentrators? Maybe some form of new "cold war", now no longer using nuclear power as a weapon but solar power? USA called it "SDI", the Strategic Defence Initiative in the 90s (Reagan/ Clinton era). Didn’t they tell us: "High energetic lasers being able to reach every point on earth will be so powerful weapons, nobody would be keen enough to attack? Now you tell me what that form of power plants would be? I seriously doubt that the real intention would be saving our environment on earth!

  29. woloabel on September 14, 2020 at 4:17 pm

    I suspect your utilitarian engineering has, before being useful,  become a shame science to humanity;  for there are freaks in our society namely militants that have access to this crap also.   In general, somewhat promising technology, but not the best and rightfully so.  I hope the best is never accessible to these stunted people of the vilest criminal type!  Sic tyrannus

  30. Team Noob on September 14, 2020 at 4:17 pm

    Range of microwave??????

  31. Marty Hastings on September 14, 2020 at 4:17 pm

    i would say "zero point energy" would be what we should invest our time and energy in.

  32. Dennis Tucker on September 14, 2020 at 4:20 pm

    I like this video. The biggest issue with this concept is the long distance wireless transmission of power. There is no affordable, safe and efficient manner to do this.

  33. Shannan Schisler on September 14, 2020 at 4:20 pm

    im sure you’ll build it yourself. I made it 2 weeks ago thanks to Avasva website.

  34. Kyle Smerk on September 14, 2020 at 4:22 pm

    A 1-kilowatt solar panel on earth is approximately 10 square feet. The 3-kilometer diameter rectennas have a 7.07 square kilometer area and produce the same about as approximately 1 square kilometer of these 1-kilowatt panels, thus making the land area cost much higher than if we just covered the planet with panels.

  35. vonshango on September 14, 2020 at 4:25 pm

    0:49 space solar power SSP will wireless transmit energy to the rectennas on the ground. 2:35 PGE and JAXA plans. 3:00 IAA 2011 said ‘there are no fundamental technical barriers to prevent the realization of large-scale SPS platforms…" highlighting 3 approaches: a) solar panel photovoltaic then transmit by microwave beam b) ditto then transmitted by multiple laser beams 4:35 c) mirror array to smaller photovoltaic and transmit by microwave (most viable). 5:55 the transmission of energy over long distances using microwave or lasers is long proven.

    From raspberry pi’s to this very good videos. Using this for a school project. Thanks.

  38. K Krolik on September 14, 2020 at 4:29 pm

    Cheaper and more reliable will be focus on build commercial Liquid fluoride thorium reactor (LFTR)
    At this moment China make significant investing quite in this technology they goal is : to obtain full intellectual property rights on this technology.

  39. nelson 128 on September 14, 2020 at 4:31 pm

    very good video , please make more videos , mining asteroids is very important to the developer of the space travel in the future is the motor of micro economy great idea 😀

  40. Easter Stedman on September 14, 2020 at 4:31 pm

    Go to Avasva webpage if you’d like to know how to build it. Good solutions for everyone I think

  41. hameed kv on September 14, 2020 at 4:31 pm

    can these signals( signals from satellite ) produce electricity

  42. Laticia Cull on September 14, 2020 at 4:33 pm

    Go to Avasva eco blog and learn how to do it.

  43. jack regans on September 14, 2020 at 4:34 pm

    Will it ever be economically vayable?

  44. Tejan cham on September 14, 2020 at 4:34 pm

    Just thought of it

  45. christopher decastro on September 14, 2020 at 4:35 pm

    It’s just short time it can used as high energy weapon

  46. Ethan's World 31 on September 14, 2020 at 4:35 pm

    The only short term answer to make this system work is create a super super super energy efficient battery storage method. Then create a solar power plants on the moon to charge large batteries 24/7 and send the battery’s back to earth by doping them into the earths oceans for recovery. We can be charging battery everyday all day and dropping them back on to the earth. Not only that … but we can create a moon or space mining station … where we will use only space material to create the batteries. Combining theses two methods. You would have unlimited material for battery and unlimited energy from the sun. After achieving this, use can use the solar energy from space to launch the battery back into the earths atmosphere. All elements needed to make this possible are already in space. We can do for the short run … until we figure out how to beam energy back into earth correctly. Also many of us on earth are trying to achieve ‘Fusion" we should build a ‘Fusion" reactor on the moon and use the sun power to quickly learn how to make ‘Fusion" work, instead of doing it in a lab on earth with limited power. Also there is no gravity in space and this may prove to be the missing factor in making " Fusion’ Work and Why it’s not working on the ground on earth. My Name is Arafat Shabazz and this is my projection stated on 11-13-2019. Mark My Words ….

    Good presentation. Subscribed 🙂

  48. Electro-Cute on September 14, 2020 at 4:36 pm

    This is the legit way of making space beamed super weapon.

  49. winfhhsfj48558vggf on September 14, 2020 at 4:37 pm

    OMG! what a amazing space weapon! just think what this could do to You if it hit you. it could heat a Tanks up so much they blow up. Think about it.

  50. Float Circuit on September 14, 2020 at 4:37 pm

    Fantastic video, James! I’m adding this to my bucket-list of space-based things to help achieve. Space is perfect for capture and transmission, wireless communication systems, sustainable mining, and ecologically favorable mass-manufacturing. Yesterday (as of this writing) a supply chain management said something to the effect of: "…the key to space isn’t bringing down the cost to launch, or targeting asteroids, or furthering space research. The key to making significant progress in our space efforts is establishing relevance in our mission, and this viewpoint has since stuck with me. That’s probably why NASA’s space visions change every few administration cycles: I don’t think too many people truly understand the relevance of space to the civilizations of Earth. All that aside, this was a wonderful presentation, and I hope you get to see space-based solar power generators within the next one or two decades. My research focusses on how to bring down the cost of getting to orbit, from $5000/kilogram to $0.10cents/kilogram (on par with the mileage of today’s cars). In my view, this requires the elimination of rockets as a means of transport, which begs the question of how else we can get resources to and from space. The problem requires an incredible reconsideration of the premises on which our propulsion systems are based, and the realization that our technologies could do much better for humanity than we have so-far seen. Space is a boundless frontier, and I’m glad that I’m able to find communities of people such as this one, where people are interested in venturing to the stars in pursuit of a better life.
