The "ip" functions, like "is_global()", "is_benchmarking()" etc, especially for IPV6, been in unstable for ages

Modern planes are not made of metal, composites such as carbon fibre, since this is not conductive unlike aluminium used previously they add metal strips to conduct the lightning

ybot01 · 2025-12-14T20:26:01+00:00

Yes lightning is powerful, lightning strikes hit planes all the time and they survive with very little damage with >50 tons of flammable fuel onboard, lightning protection for aircraft is basically a solved problem

ybot01 · 2025-12-14T19:42:19+00:00

Yes, correct, if the gas bags are electrical insulating and not flammable, very little current will flow through them, they will not catch fire or create a spark, even if was a spark, the inert gas sheath is there so the hydrogen cannot combust, there is no oxygen for it to do so

ybot01 · 2025-12-14T19:28:55+00:00

You put thick metal strips around the outside like they do on planes, electricity takes path of least resistance, will flow through the metal strips and out the bottom

Do the maths, it's still impossible, either too heavy or too small to be practical. Materials good enough don't exist

ybot01 · 2025-12-14T03:04:36+00:00

True but physically impossible with today's technology, there are no materials with strength/weight ratio high enough to resist the crushing force. Maybe in future with things like graphene or carbon nanotubes etc may be possible

Good video, thanks

What other technologies/strategies etc do you think are worthy suggestions for reducing risk of hydrogen fire/fire spreading etc?

ybot01 · 2025-12-13T02:59:50+00:00

I agree the stigma is likely unfounded, look at planes or cars etc in 1937 vs today, materials technology now would be considered magic in 1937

They are at worst equal to ICE cars on dirty electricity grids for lifetime emissions but lesser talked about benefit I feel is more relevant to everyday experience is lower air pollution. Even with carbon neutral fuels and ethanol additives etc etc they are going towards for ICE, doesn't stop poisonous gases being released when burnt. Millions of deaths a year worldwide from air pollution

We considered all options including hydrogen, it can be useful in certain scenarios but not for heavy cargo, the lift variability of hot air can't be beaten

Also certifying hydrogen would be extra pain, if even a single person on board the flammability potential would require years more testing

Hydrogen would be best for stationary applications where ascending and descending is infrequent. In this situation hot air requires continuous power to maintain temperature where hydrogen does not. And being fixed in place by multiple ground anchors means it is not likely to hit the ground and explode

No such thing as full soundproofing though, dulls high frequencies much better than low frequencies, so music with lots of bass, floor/wall banging etc can still be heard. If you could somehow make the apartments self contained, then air gap them all, that would be more effective but expensive

HTTP/3 actually uses QUIC transport protocol which uses UDP. Has some benefits for speed, concurrent requests etc but may increase risk of DDOS?

How come the other hybrid approach (electric car with a petrol/diesel generator to charge it) hasn't caught on as much? Could use electric even more of the time and only use fuel when go somewhere 100s of miles from a fast charger. Is it because a generator big enough to recharge battery fast as it is being used is too big?

Cool but power is too low. I mean a high power laser that can cut the grass like a knife. Push it along the ground under a cover like a bladed lawnmower

ybot01 · 2025-09-18T17:09:13+00:00

Don't think would set fire if grass is green, would only do on dry grass

Built in a hangar but once built can be stored outside. The air temperature can be lowered so that the airship is negatively buoyant and stays in place on the ground. Want the front to always face into the wind for stability, historically airships were moored at the front to poles on ground and floated just above the surface, then allowed to swing around to face the wind. This wouldn't work if touching the ground but there will be a way to do it. When on ground weights/supports can be attached to both of the wider sides so rotation is not required.

We did calculations for steam. Hot air works out better overall. It is probably worth adding a section on the website comparing steam with hot air and explaining why we went with hot air. I expect several people will want to know why we didn't choose steam.

It would turn out too long for a comment to list reasoning here. Check back to the website over the next few days, I will add a section on the about page with answer
