Future of Microwave Power Beaming

Safe and Continuous Power Beaming Microwave (SCOPE-M) is an NRL research project which delivers one kilowatt of electrical power at a distance of a kilometer using a microwave beam. To learn more about this project, go to: ieeexplore.ieee.org/document/9662403.
SCOPE-M is built of tens of thousands of x-band antennas. Each of these antennas is connected to a small rectifier diode that diode converts the incident microwave power into DC electrical power. This demonstration paves the way for power beaming on the earth and from space to the earth.

Video carefully avoids to state that the overall efficiency of the system is 1.8%. Input power was 91.2kW at the TX antenna, out of which 1.65kW was produced at the receiving side. ieeexplore.ieee.org/mediastore_new/IEEE/content/media/9171629/9673801/9662403/roden.t2-3130765-large.gif

[@1209832asdasasd]

The authors' paper carefully explains the link efficiency. It describes how the efficiency would be significantly increased by modestly increasing the receive antenna's size or by using a power amplifier that's better matched to the transmitter antenna size. Any rapid demonstration put together with things on hand will involve compromises.

It's not finite fuel power supply source though, so even if getting a small percentage back if that were true, it's still a percentage not being depleted at either end because it's solar powered. It's different context from limited resources power supply.

[@speter60]

So, does the other 98% heat the air, and raise global warming?

[@davidwright8432]

How closely can you focus the beam? As someone with a pacemaker, who's been warned to steer clear of high powered military or air traffic radars, which risk disrupting function, I'm interested in energy density in watts/square meter, beamwidth at various distances from transmitter, and such.

[@herzogsbuick]

i built my first crystal radio set when i was like, i dunno, 6, 7. and when i realized it was being powered by the radio waves themselves, i took out my invention notebook and drew a satellite beaming solar power down to earth. now i know i haven't gotten smarter since then, but i have learned things that i didn't address, nor were addressed in the video or in any of the comments: w/m^2 at a given radius, what is the divergence of the beam, what is the efficiency of the system overall (you said 100kW transmitter for one of the experiments, but that obviously doesn't mean you're pushing it to 100kW, but amplifiers also have losses) it just seems dangerous for many situations. most, perhaps. emphasis on "seems" though, because i don't have that data, you do, but you haven't shared it with us

[@justinharder6420]

[@bensplace]

Could there be other ways of getting the energy to Earth? Even if it was only reliable on clear days it could be sent to Earth and stored in a battery.

Tesla had some big tower that was to broadcast energy in his day. Not sure what frequency. or power source or what the receivers were to be.

[@hipstercrab5886]

have you ever considered going to space on microwave beams ? here's how it (theoretically) going to work : you take a spaceplane, make large portion of it's surface into a microwave reciever and launch it above the ocean, where, along it's way there are several ships or stations with nuclear or later - fusion reactors onboard, cooled by ocean water and huge antennas to beam power to the space plane of course it needs some serious material science to construct plating that is both heat-resistant and can receive or let through most of the microwave spectrum and plasma-arc engines of course, running on burning and ionising air in the atmosphere and on liquid hydrogen in space the upside of this method of spaceflight is that you don't have to carry a reactor on the plane itself, which both saves mass and makes the plane safer (no nuclear contamination in case of a crash) of course this concept needs some work and A LOT of money to accomplish, but at least it seems feasible Crab out

[@prakasamkannadi7616]

If power can be delivered to more distance point using microwave beam, at least on Earth surface ( at present not on Ocean surface) transportation canbe revelutionised with a big zero polution . I think so.

[@sampleoffers1978]

I don't know if relays involving solar or wind powered balloons/drones/zeppelins are even necessary for safety or signal strength, but maybe that's additional options if needed. Also if "heat batteries" are a real thing, whether graphite or other, it seems like continuous beaming may not even be necessary over night or in bad weather. Other thing is if there's more options than solar power, like if a "glide satellite" put in lower atmosphere could beam it's heat shield energy power. Obviously land based, remote nuclear plants and wind turbine locations(alongs high ways/waterfalls?) etc, also paths. This is more ways to export energy sales is more incentive, for at least a decade. Varied locations could create more civil energy markets/participation.

[@jeechun]

terrestrial energy production (from renewable sources) cannot be scaled up like SBSP (Space Based Solar Power). Actually, SBSP is a renewable energy. With the least environmental impact.

[@sampleoffers1978]

​@@jeechun I don't know if that's accurate but...land based transmission might make sense for beaming from dessert solar...offshore wind...geothermal locations...compressed air sites...hydro electric sites..."Gravity battery" mountains and nuclear power plants built in remote locations. So while terrestrial beaming might yield small percentage, it's potentially big diversified energy pie with many sources. A "gliding satellite" might only need to cross the continental U.S for five to ten% of energy power, contributing adequately to national grid.

[@ericmatthews4598]

Wait. If we collect in space and beam to Earth, how much is lost through the atmosphere? Same as lost from sun beaming through atmosphere directly?

[@AlexanderStone]

Now hit a large rotating superconductor with the beam! BAM, Warp Drive!

[@felipedeluz]

Did Tesla done it before or was his project something different?

[@dcanbazlar]

Does energy lost is like distance square or is it like laser. What is the caveat for much more distance beaming?

[@dcanbazlar]

Also, how much heat occur in the receiver side?

[@alexvasilescu8245]

Future of Microwave Power Beaming? 100kW to get 1.6kW at 1km away? that is 1.6% efficiency. So, if you can convert 100% of the suns energy in space and send it back to earth with a subsubzero efficiency, you get way less than current PV solar cells. Also, comparing producing electric energy to transporting electric energy???

@@TheExplosiveGuy I would bet my life that we can already do that without implantable electrodes. Have you seen nanoradios?

Just target the language and speech centers in the brain where a whole host of magnetite is (left temporal lobe) is and you can get a readout of action potentials. Many brain tumors arise from the left side of our brain. Maybe because of targeted electromagnetic energy? Or that the frequencies we’re bombarded with on a daily basis are interacting with the magnetite and other nano metal particles in that area?

[@jima4656]

They used how much equipment? and lost what percentage of power? And made how much area uninhabitable? in order to move enough energy to power a small window-shaker type air conditioner? They call this green energy production, but this system did not create any energy, it just moved it from one place to another, with a loss.

[@sampleoffers1978]

Not really a loss in this sense because, when oil burns off it is a loss, even when it's used efficiently. When sun power is not fully captured, that's just normal. We don't really deplete the sun, we just don't optimize the scraps of solar it throws us anyway.

[@wreptar1938]

I agree. A bit misleading since they don't divulge the whole production cycle, just the fact that the transmission portion is green.

[@terrysworkbench]

You will never be able to beam power from geosync in any usable way, due to the inverse square law. Please quit promoting that as a possibility. Geosync is 22,500 miles. Do the math. I am not knocking the great work done here.......... but we already know the numbers if you have 100% efficient transmitters and "rectennas".

[@rfengr00]

Looks like they are able to focus the beam, rather than a collimated beam, so that will help some. Though maintaining that focus over distance may be tough.
