the key problem for the electric plane is the conversion efficiency. converting solar to electricity, then converting electricity to laser, then converting laser to electricity is a complicated process. a lot of energy will be wasted because the limited conversion efficiency. A better way will be using shaped EM wave.

You can build well guarded nuclear plants deep in ground in isolated spots if you can transmit the power wirelessly....Then you can optimize solar,wind,geothermal, etc renewable power at same time..Perpetual closed track trains generating wind power is possible, and it's not perpetual because the batteries and engines still have charging/running limitations, but that's the only limitations due to help of inertia, momentum, kinetic energy etc

1x1 m of land on the surface gets around 1kw and a solar panel can produce say 150-250 w of energy. your figures are a bit low.

This idea gets talked about a lot for some reason, probably since it’s fun to think about. However, unless the cost of a football field sized solar array, the launch cost, and the attached satellite were all less than about a million dollars there would be no incentive to use this. This would be at least 1000x more expensive that just using turbine engines. Don’t get me wrong, electric aviation is obviously the future of short haul commercial aviation, but this idea is just as silly as ever.

using laser to transfer energy means using almost the same equipment of laser weapons. therefore, to prevent damage airplanes have to have mirror coating.

I am surprised they haven't mentioned the possible harm laser and microwaves can have

Other then cost it would be nice to know what other difficulties lie in building this kind of infrastructure otherwise the legitimacy of this should be meet with high degree of skepticism.

Any information about the science and technology behind this? I doubt the whole story. Even wireless charging of cars is not used because of the high losses. And this would only need lower distances than 1m. Over some 100m the tiniest motion of one of the antennas will cause interruption of any transmission. Next issue is the laser to prevent birds getting grilled in the beam. What if the whether is cloudy and no laser get´s through? Energy supply only while the sky is clear?

I still suspect that the orbiting solar panels will require a very long extension cord. Even wireless has wires.

I sure wouldn't want to live anywhere near that microwave collecting farm. You go first man! lol

The energy crisis in the 1970’s had this concept explored in depth with Rockwell International conceptualising an orbiter needed to get those satellite power stations into orbit, called the Star Raker. They never produced a working model, and they fell into liquidation, thus kicking the Star Raker into the long grass. With an energy crisis on our hands once again in a society more dependent upon Thomas Edison’s game changer that is electricity - with a higher population too, adding to the supply and demand aspect - who knows? Maybe the concept of satellite power stations will be revisited with results that will change the energy industry forever like Rockwell International could only conceptualise.

if that happen could we be a type 1 civilization?

What if there was a huge solar power farm in geostationary orbit, beaming lasers constantly to the same solar panel. That would be cool.

Nikola Tesla proposed this very thing along time ago but not not sourcing power from space but rather the earths upper atmosphere.

I didn't watch the video because this idea of wireless power will replace the old power lines on the streets of America, can't wait for it to happen.

There would be a cheaper alternative without deploying anything into space, natural and safe. Using rectennas / radio telescopes to capture, and Schottky diodes, tuned to pick up the required Frequencies. If you can convert small amounts of energy, such as shortwave band 15Mhz-40Mhz from Jupiter planet, and also tune in on other frequencies such as our sun and other planets. It could very much open a new door into collecting free energy forever, day or night, wind or no wind, gas or no gas and on earth or off earth and so on. For as long as the planets and suns are around and operating the way they do, then they are a safe supply of energy possibly beneficial to run small electronic devices or to store their wasted energy into something greater. If we can tap into their frequencies and collect and convert, less may well be more long term.😘

No, it's just not cost efficient. For the energy that needed to send those things to space is enough to fly an plane for years. Not to mention how many of the solar orbit energy things needed to power just one plane. Besides that, the energy lost due to decay and conversion is too high. We also have maintenance, legal and public relation issues to talk about. It is just not a good idea

Last, since litterally every plane in the sky is monitored and goes through a specific pathway, this puts it somewhere similar to cabled buses, which no one complains about. Commercial airliners which would be the biggest entities using this kind of tech will only need battery enough for takeoff and landing and etops.
