When my country Turkiye was struck by two massive earthquakes last year one of the most crucial disfunction was the lack of communication. We made a grave mistake by installing majority of the cell towers on top of the residential buildings. In the earthquake most of them were collapsed. This is a remarkable platform for cases like that.
The more robust alternative is the solar covered and powered airships.. they can remain airborne carrying a greater payload.. longer and are less fragile caught in weather. BBC have also covered these previously. The idea of using hybrid air vehicles to provide emergency communications and disaster relief using aero stats goes back to Skycat if not earlier ... and the Banda Achai Indonesia Thailand boxing day Earthquake and Indian ocean Tsunami. DARPA initially funded the current flying prototype .. for use over Afghanistan .. Long endurance intelligence gathering and monitoring and ground coordination.

Aurora Flight Sciences had multiple models of unmanned aircraft flying 80-100,000 feet up for months at a time over 30 years ago. This one looks lighter and more advanced as it should 30 years later but this isn't that pioneering.
The thing that really gets me about these is how similar they look to the Wright bros original plane, super efficient twin propeller design, thin long wing as light as possible, every piece optimized, skin covering over frame. Incredibly similar to that plane well over a century ago.

How do you communicate with the plane in order to control it autonomously over areas without cell cover? Is it by satellite? And do the altitudes the planes may use conflict with other planes? Like if 10 years from now, 30% of the US cell network demand is covered by zephyr planes, how disruptive is that to other planes and rocket launches

Okay I have one small problem with the whole "it will replace 200 cell towers" part. Will the phones be able to transmit back? It's a 2-way communication lol. If a cell tower is 1 unit away from you and that thing replaces 200 cell towers, which means roughly a 14x14 tower grid, you will be as much as 7 times further from a tower. The inverse square law tells you that 7 times increase in distance means 7^3 times increase in losses. Your phone will have to transmit at a 343 times higher power output for the same reception and that is not accounting for weather and you know things like... LIVING ON THE GROUND FLOOR OF A 20 STOREY CONCRETE BUILDING as that antenna will be transmitting and receiving straight down. I'm tired of people that think radio is just magic...

The first aircraft of this type was flown in the 1960s by Bob Boucher in California. It was balsa wood and spruce had solar cells generation 1.0 and NickelCadmium batteries. It used a DC Brushed electric motor.
Why not a launch battery. It uses the battery to push the plane at full throttle through the weather and then when it’s depleted it’s dropped with a small parachute and retrieved. This would allow them to launch the plane anywhere and even from boats like for the military.
This could become a highly localized star-link type network with flexible coverage depending on local usage. It would reduce the amount of space junk burning up in the atmosphere

There is no reason it couldn't be used for Internet as well and if it were able to do that they it would make starlink obsolete, as it would be much cheaper, would not leave debris in the atmosphere and is better for the environment. It would also give more consistent coverage as it can stay over specific spots whereas starlink orbits.
@@Alex-cw3rz it could, but it would have to have really good battery technology which could power both the plane and the satellite internet service, plus have the scale to deploy it. Honestly I don't see these taking off like that, and in the case one of these crashes, there's a very real possibility of it damaging things and even killing people. Satellites burn up in the atmosphere.
It's just more flexible on where you want to put it. Starlink has best coverage, but it is in fixed orbit and much higher up which required a satellite dish, less localized signal than land based tower or glider like this which could talk to phone directly. Starlink phone isn't happening yet because it would need a big antenna, they couldn't figured out how to make it truly handheld yet.
I’m polish and I have my own company called Kurva space solutions Ltd, I make ballon using skin of 42,000 polish sausages. , it can fly to over 135.000 miles , it currently is in geostationary orbit , it make this zefer look like paper toy, I’m fully qualified electronics, physics, chemistry and nuclear engineer, I also have degree in maths , thermodynamics, biology,quantum mechanics,and palaeontology, but in UK where i live I work night shift in sausage packing factory, I’m best designer in world, like betman.
Satellites: consider the amount of energy expended to get those few kilos in space. (i.e. they don't stay above "without power": mega joules of energy were applied to get them them aloft... as well as speeds to stay aloft)
It would be funny if some companies were able to do this permanently and put starlink out of business because these probably cost a fraction of what it costs to put a star link up
I can see a possibility of a modified aircraft like this in space exploration, specifically in the upper atmosphere of Venus where the temperatures are not so extreme. Imagine a capsule deploying this and being able to survey the surface, take atmospheric measurements, possibly look for signs of life in the Goldilocks zone of Venus. It's in the realm of possibility!
If this works then I would argue that having ultralight re-usable planes like these is cheaper and more environmental friendly than launching thousands of satellites into space that burn up every 5 years. Furthermore there have already been near accidents between space junk and satellites.
But it crowds up our orbit and greatly increases the probability of space junk ruining all the satellites. We're pretty fucked if that happens, this could be an alternative to some things
@@RicardoMusch | Satellites burn up completely when deorbiting. Cases when some parts reach the surface are very rare. Nothing is perfect, and if you populate stratosphere with tens of thousands of these planes they will sometimes fall due to malfunctions creating junk and endangering the regular air traffic and people on the surface. The specific payload capability of solar planes is extremely low, and they should be 100 times larger to carry a meaningful payload like cell-station. So you should add a whole plane with a wingspan of a regular airliner to each cell-station
Don't say anything about the starlink sats failing all the time lol, or muskrat letting his politics screw his businesses. Zephyr could go where Starlink isn't allowed to, either because governments or militant groups prevent it legally and through jammers, also anti-sat weapons if war broke out, or because muskrat just does a racism.
@@ThePalisky Fact check: *BOTH* Starlink and AST SpaceMobile have demonstrated direct-to-cell voice and high-speed internet. But they are not equal: Starlink is faster and lower latency than AST. *Firstly, I dispise Elon Musk's politics, conduct, and power. The following is a compassion of technology.* The Starlink constellation is in low-earth orbit (LEO), giving it lower latency (~50ms). AST satellites will be in medium-earth orbit (MEO), and will have 3x higher latency (~150ms). AST currently only has 1 demo satellite in orbit in MEO (BlueWalker 3) used to demo direct-to-cell voice and data transfer, with download speed peaking at 14Mbps. Starlink has 38 and counting direct-to-cell capable satellites, and recently demonstrated a video call with a peak download speed of *17 Mbps.* Don't get me wrong, I think AST will likely be successful, especially with recent partnerships with major mobile providers like Verizon. More competition will hopefully keep prices from getting too insane. Ultimately, Starlink has an advantage with lower latency in LEO, unless Amazon's Kuiper constellation ever gets off the ground.
@@radfoxuk8113 Generally, I agree with your points. Although nothing would stop jamming either Starlink or Zephyr based radio signals. It's good to have options. But it seems that Zephyr has a long way to go to demonstrate its potential.
Imagine a line of these, connected by wire so that the sun never sets on the chain, the planes in the shade getting charge from the ones in the sunlight. Obviously, the weather will be a real challenge to solve, but a giant structure like that could change the world.
If your country only needs a signal for a day! These batteries won't last and the plane won't be able to stay up. Meanwhile you need 3 satellites to cover the whole world. This plane is a tiny step towards making passenger plane's electric but that's about it.
i'm afraid starlink has already achieved direct to mobile connection, so that's that avenue closed, it was a good idea at the time but I suspect has limited use now
odd how he admits that to handle the bandwidth of modern cell systems a low earth orbit satellite would need to be enormously big and expensive but plans to put the same capability on a 75 kg aircraft...
The big difference is in altitude which allows a standard cell phone the ability to have two-way communication with this unmanned aircraft. The plane would act as a super tall cell tower. You can't do that with a satellite. You would need a special satellite phone for that.
@@spinav8r Newest generation of Starlink is already performing direct-to-cell capabilities, with no different handset needed. So that kinda disproves that. And cruising at 75000ft already loses the line of sight benefit of cell towers by placing the receiver on the other side of the entire weather layer from the handset.
@@spinav8r A cell tower is less than 1000 ft, this cruises around 15 miles, LEO satellite constellations are around 250-350 miles, GEO are around 22,000 miles. This plane is kinda just another intermediate step in that chain of options, so it will have tradeoffs of both its lower and higher altitude alternatives. It can't magically do the same job and be lighter than both satellite or cell tower equipment packages
side effect, blocks a tiny amount of sunlight without creating a shadow (bc its in the stratosphere) and helps cool the earth the tiniest bit (by blocking a small amount of sun)
On RUclips, many of those generic, non-specific comments are paid-for, AI-generated by site owners to generate more revenue. I don't see any of those here ... a couple of nonsense "Hi from xxxx", or those immature "First" posts are always scattered around ... but they're real.
4:40 The quick close up scene of the the flood, the house in the center has a quarter of its roof break down. The smoke resulting from that looks faked/CGI. I'm not saying it is, I'm saying the smoke looks weird. After all, I've never seen a scene like that for my brain to compare it. And nowadays, I've seen so much of both reality and movies that I can't always tell the difference between real and VFX. This is a stretch, but can anyone tell my why that smoke is either real or fake? It would be very helpful if I can find other footage of the same thing for reference.
It should have a detachable batery and propellor unit... so that it can climb a lot faster and once it's depleted it drops off with a parachute landing... the Zephyr continues onwards above the weather...
Unless it's accelerating vertically, its lift to weight ratio is exactly 1:1. Such an enormously long and lightweight structure simply cannot withstand large vertical accelerations.
Stay operational in the stratosphere for extended periods or time? Yes. Indefinitely? No. There's friction involved in parts like the propeller, so even if you had an extremely efficient and long lasting battery, you would still need to service the aircraft even if the propeller parts were made out of tungsten carbide.
It's not unreasonable to assume an electric motor operating in a dry, dust free, environment could run for many tens of thousands of hours, i.e. several years, without maintenance. Hard drives have been doing it for decades, even HVAC systems often have fans that run 24/7 for years at a time. Chances are you'd be wanting to upgrade the payload on a annual basis anyway, something you can't do with satellites.
My question would be : where is it after a certain period and "If it's in the stratosphere, what's filming it?" there's no other airplanes up there. or is it CGI ?
As someone that has done GIS and earth observation before, this would be invaluable for researchers. I personally dont think its a good idea to clog up the stratosphere just for phones.
Could you add a rechargeable extra removable stage to it ? So a stronger engine could run for an hour or so to get it up to the desired height and then detach and return to the launch site ?
At about 4:00 he says that power is the most expensive part of running a cellphone tower. Well if that is the case then put solar panels and batteries on the ground near the tower. Yes you may need more towers if you are on the ground, but overall I am willing to bet the cost is still lower than the zephyr at this time as ground based solar/batteries will be considerably cheaper than the zephyrs solar/batteries for any given power output and there is no power consumption for flying. If the the zephyr had power to spare then it wouldn't have such tight design challenges.
Solar thermal balloons also stay up, for up to a year. Uv degradation is limiting Factor. Much cheaper. There is one more type of 'balloon' that can stay up for decades AND maneuver, ceiling is 300k unloaded. Also steerable. No one else has thought of it yet though.

I’m polish and I have my own company called Kurva space solutions Ltd, I make ballon using skin of 42,000 polish sausages. , it can fly to over 135.000 miles , it currently is in geostationary orbit , it make this zefer look like paper toy, I’m fully qualified electronics, physics, chemistry and nuclear engineer, I also have degree in maths , thermodynamics, biology,quantum mechanics,and palaeontology, but in UK where i live I work night shift in sausage packing factory, I’m best designer in world, like betman.
You’re killing me here! LOL
Satellites: consider the amount of energy expended to get those few kilos in space.
(i.e. they don't stay above "without power": mega joules of energy were applied to get them them aloft... as well as speeds to stay aloft)
It would be funny if some companies were able to do this permanently and put starlink out of business because these probably cost a fraction of what it costs to put a star link up
Like a microfilm glider.
I can see a possibility of a modified aircraft like this in space exploration, specifically in the upper atmosphere of Venus where the temperatures are not so extreme. Imagine a capsule deploying this and being able to survey the surface, take atmospheric measurements, possibly look for signs of life in the Goldilocks zone of Venus. It's in the realm of possibility!
Oh look its the early stages of creating an arsenal bird.
This was my first reaction.
It’s like an amateur model plane but solar powered. And capable of carrying a wide variety of instruments for scientific research
Starlink has already made this obsolete since it is able to connect with mobile phones.
Maybe these aircrafts will take Starlink out of business?
If this works then I would argue that having ultralight re-usable planes like these is cheaper and more environmental friendly than launching thousands of satellites into space that burn up every 5 years. Furthermore there have already been near accidents between space junk and satellites.
But it crowds up our orbit and greatly increases the probability of space junk ruining all the satellites. We're pretty fucked if that happens, this could be an alternative to some things
@@RicardoMusch | Satellites burn up completely when deorbiting. Cases when some parts reach the surface are very rare. Nothing is perfect, and if you populate stratosphere with tens of thousands of these planes they will sometimes fall due to malfunctions creating junk and endangering the regular air traffic and people on the surface. The specific payload capability of solar planes is extremely low, and they should be 100 times larger to carry a meaningful payload like cell-station. So you should add a whole plane with a wingspan of a regular airliner to each cell-station
6:41 they went over this.
The launch really isn't a problem, you can launch from air at a high altitude if this was to serve in disaster zones etc
Don't tell the Zephyr folks about Starlink... high speed internet + direct to cell text, voice, and data anywhere in the world already exists. 🤷♂️
Don't tell you that Starlink can't do high speed internet direct to cell, but ASTS can at broadband speeds in addition to all that you mentioned lmao
Be interesting to see estimates for total cost of ownership for both.
Don't say anything about the starlink sats failing all the time lol, or muskrat letting his politics screw his businesses.
Zephyr could go where Starlink isn't allowed to, either because governments or militant groups prevent it legally and through jammers, also anti-sat weapons if war broke out, or because muskrat just does a racism.
@@ThePalisky Fact check: *BOTH* Starlink and AST SpaceMobile have demonstrated direct-to-cell voice and high-speed internet. But they are not equal: Starlink is faster and lower latency than AST.
*Firstly, I dispise Elon Musk's politics, conduct, and power. The following is a compassion of technology.*
The Starlink constellation is in low-earth orbit (LEO), giving it lower latency (~50ms). AST satellites will be in medium-earth orbit (MEO), and will have 3x higher latency (~150ms). AST currently only has 1 demo satellite in orbit in MEO (BlueWalker 3) used to demo direct-to-cell voice and data transfer, with download speed peaking at 14Mbps.
Starlink has 38 and counting direct-to-cell capable satellites, and recently demonstrated a video call with a peak download speed of *17 Mbps.*
Don't get me wrong, I think AST will likely be successful, especially with recent partnerships with major mobile providers like Verizon. More competition will hopefully keep prices from getting too insane. Ultimately, Starlink has an advantage with lower latency in LEO, unless Amazon's Kuiper constellation ever gets off the ground.
@@radfoxuk8113 Generally, I agree with your points. Although nothing would stop jamming either Starlink or Zephyr based radio signals. It's good to have options. But it seems that Zephyr has a long way to go to demonstrate its potential.
Imagine a line of these, connected by wire so that the sun never sets on the chain, the planes in the shade getting charge from the ones in the sunlight. Obviously, the weather will be a real challenge to solve, but a giant structure like that could change the world.
With 5 of these,you can have full telecom company in a country.
And they'll still charge 5% of monthly median income for it 😆
problem is ASTS already solved this...5G broadband direct to unmodified cell phones from space
If your country only needs a signal for a day! These batteries won't last and the plane won't be able to stay up. Meanwhile you need 3 satellites to cover the whole world.
This plane is a tiny step towards making passenger plane's electric but that's about it.
i'm afraid starlink has already achieved direct to mobile connection, so that's that avenue closed, it was a good idea at the time but I suspect has limited use now
odd how he admits that to handle the bandwidth of modern cell systems a low earth orbit satellite would need to be enormously big and expensive but plans to put the same capability on a 75 kg aircraft...
The big difference is in altitude which allows a standard cell phone the ability to have two-way communication with this unmanned aircraft. The plane would act as a super tall cell tower. You can't do that with a satellite. You would need a special satellite phone for that.
@@spinav8r Newest generation of Starlink is already performing direct-to-cell capabilities, with no different handset needed. So that kinda disproves that. And cruising at 75000ft already loses the line of sight benefit of cell towers by placing the receiver on the other side of the entire weather layer from the handset.
@@spinav8r A cell tower is less than 1000 ft, this cruises around 15 miles, LEO satellite constellations are around 250-350 miles, GEO are around 22,000 miles. This plane is kinda just another intermediate step in that chain of options, so it will have tradeoffs of both its lower and higher altitude alternatives. It can't magically do the same job and be lighter than both satellite or cell tower equipment packages
It's rare to see a host so excited about their topic
This technology feels 40 years too late. Should aim for low cost solutions for companies who can't afford orbit.
You're 40 years too late
Everything about climate change is 40 years too late.
We will pay dearly for our ignorance, arrogance, and greed.
This is one of the case that when you see it and know nothing about the project you'll think it's an alien
Starlink says hi....😂
side effect, blocks a tiny amount of sunlight without creating a shadow (bc its in the stratosphere) and helps cool the earth the tiniest bit (by blocking a small amount of sun)
Are all the comments for real? :)
On RUclips, many of those generic, non-specific comments are paid-for, AI-generated by site owners to generate more revenue. I don't see any of those here ... a couple of nonsense "Hi from xxxx", or those immature "First" posts are always scattered around ... but they're real.
Kenya. I was super excited about that bit. My homeland
A business owner who actually knows their company and can answer questions, very refreshing.
Planned questions and practiced answers
host moves like Jim Carey lol love it
British people are eccentric in nature 😃we invent things because we have enquiring minds and the usage usually follows…👍🇬🇧
I hope this contraption doesn't have a malfunction, drop to 30,000 ft, and collide with a passenger aircraft.
Starlink could be getting some competition.
We were there before you guys. 60k plus feet. Planning to fly and stay around for atleast 3 months. A happy note from india.😊
One super volcanic erruption brings it down.
😂
So one is lost every 100 years
若かったらこういう会社で働きたいですね。世界を情報通信で平和にできる気がする。
Going Clean Energy and Sustainable is the way forward.. thank you Zephyr ❤
4:00 problem is that cell towers don't fully communicate using wireless tech, but also with cables, whether fiber optic or copper.
4:40 The quick close up scene of the the flood, the house in the center has a quarter of its roof break down. The smoke resulting from that looks faked/CGI.
I'm not saying it is, I'm saying the smoke looks weird. After all, I've never seen a scene like that for my brain to compare it. And nowadays, I've seen so much of both reality and movies that I can't always tell the difference between real and VFX.
This is a stretch, but can anyone tell my why that smoke is either real or fake? It would be very helpful if I can find other footage of the same thing for reference.
Am just proud to be a kenyan where the solar powered aircraft will be launched
It should have a detachable batery and propellor unit... so that it can climb a lot faster and once it's depleted it drops off with a parachute landing... the Zephyr continues onwards above the weather...
Finally my Jeddak, a ship that is powered by the sun
Its the future...
Salute you from Bangladesh
It has a very high lift to weight ratio so it doesnt need much power or lift to stay up.
Unless it's accelerating vertically, its lift to weight ratio is exactly 1:1. Such an enormously long and lightweight structure simply cannot withstand large vertical accelerations.
In an emergency, you don't have to wait that long, you can launch from another airplane.
Stay operational in the stratosphere for extended periods or time? Yes. Indefinitely? No. There's friction involved in parts like the propeller, so even if you had an extremely efficient and long lasting battery, you would still need to service the aircraft even if the propeller parts were made out of tungsten carbide.
It's not unreasonable to assume an electric motor operating in a dry, dust free, environment could run for many tens of thousands of hours, i.e. several years, without maintenance. Hard drives have been doing it for decades, even HVAC systems often have fans that run 24/7 for years at a time. Chances are you'd be wanting to upgrade the payload on a annual basis anyway, something you can't do with satellites.
My question would be : where is it after a certain period and "If it's in the stratosphere, what's filming it?" there's no other airplanes up there. or is it CGI ?
As someone that has done GIS and earth observation before, this would be invaluable for researchers. I personally dont think its a good idea to clog up the stratosphere just for phones.
6:23 dear Video editor, please next time, kindly show the actual Kenya on the footage
Checkout Kia aerospace from NZ...clearly a competitor
they should use a secondary temporary aircraft that can take it up to 60,000 feet
Could you add a rechargeable extra removable stage to it ? So a stronger engine could run for an hour or so to get it up to the desired height and then detach and return to the launch site ?
now the question is....can you attach missiles to it?
all fun and games until it gains sentience and starts playing boss music
I am impressed, especially that it can stay powered overnight, and battery Cycles being the only limiting factor 👍👍
Lucky guy that took the photo of the aircraft!
KENYA - The country of all possibilities.
Everybody hyped till the sky starts singing Latin.
At about 4:00 he says that power is the most expensive part of running a cellphone tower. Well if that is the case then put solar panels and batteries on the ground near the tower. Yes you may need more towers if you are on the ground, but overall I am willing to bet the cost is still lower than the zephyr at this time as ground based solar/batteries will be considerably cheaper than the zephyrs solar/batteries for any given power output and there is no power consumption for flying. If the the zephyr had power to spare then it wouldn't have such tight design challenges.
It’s a free power launch satellite. No rocket required 👍🇬🇧🌈♥️🙏
I wonder how much more additional weight and power requirments will be added if you ask this aircraft to do more than just aimlessly fly
Solar thermal balloons also stay up, for up to a year. Uv degradation is limiting Factor. Much cheaper.
There is one more type of 'balloon' that can stay up for decades AND maneuver, ceiling is 300k unloaded. Also steerable. No one else has thought of it yet though.
This will create something incredible in the near future, I can feel it.
This is a groundbreaking step to fixing the global warming problem.
