Is it? The fact it needs to be above absolute zero makes me think it’s instead just a clever way of harvesting the thermal energy of the environment without large apparatus.
It’s definitely not extracting energy from the vacuum. It’s converting latent heat energy into electrical energy due to clever engineering and the quirky properties of graphene.
Sadly it’s not extracting energy from the quantum flux :) But happily, it is extracting energy from the heat of the world – of which there is plenty (enough for us to treat it as unlimited).
They must have made some huge advances since the last time I checked in on them because they haven’t exactly been considered sophisticated in the art of rocketry for a couple centuries now. They first had a person in space in 2003 and they’re still using the same Shenzou line of rockets since that time. They’ve had some controversies about where their boosters are landing and covering people with Hydrazine which is also an outdated fuel type, imo.
Yeah, a space station is actually pretty impressive given that no other country besides the US and Russia have one, and that will be gone by 2030 with no plans for a replacement. If you don’t think a Space station is impressive then you’re very ignorant. So in a few years China will have the only space station in space. They launch multiple rockets per week while the US just has SpaceX launching at a similar cadence. Go stick your head in the sand if you want, but outside of SpaceX the Chinese have a better space program and just saying “we did it x many years ago” is completely irrelevant to today. All of the tech isn’t here anymore. There is no space shuttle. The SLS is a boondoggle that will never fly after a few expensive Artemis missions. ULA is basically bankrupt and trying to get sold. Boeing Space is a disaster. Today is what matters and I believe Chinas space program is in a much better place than ours. Today. It’s a result of attitudes like yours that handwave away anything that China does and leads to stagnation and complacency and corruption
The ISS was designed and built in various countries across 4 continents in the 80s and 90s, I would hardly call it only Russia’s and the USA’s. I honestly respect India’s Aerospace more than China’s current level of technology. Even the UK, who historically have had no interest in the field, are in the midst of planning 2 massive Space Ports in England and Scotland.
I’m not dismissing the failures of USA Space Program, it’s so inefficient to its core that Elon Musk and Jeff Bezos each started their own rocketry firms that blew conventional compartmentalized industry pricing out of the running. I’m just striving for accuracy of Chinese Failures. They’re not currently neck and neck with us, at all. When they figure out how to make coal powered rockets, then maybe I’ll sweat a little, lol.
This new plane is a hypersonic weapon delivery drone, barely related to the SR-71 aside from the speed it can travel.
As to the sixty years thing, satellites made spyplanes nearly entirely obsolete and traditional aircraft with stealth technology covered the remaining cases well enough that there wasn’t a need for more speed. Research went into making missiles better instead, and this is designed to be a launch platform for those missiles.
Then why do we still operate the U2? SR-71 was operated all the way until 1999. Hubble was launched in 1990 so the large mirrors for spy telescopes had to have been in use well before that.
This is a fantastic idea, here in the UK we’ve just been dumping raw sewage in the rivers and poisoning the coast because it’d cut into water companies record profits to treat it (also Brexit chemical shortages or something)- if we can turn the poop into something useful that can sell then the won’t let a drop off that precious filth go to waste.
This cable length is 765km, but in the Canadian province of Manitoba we have a 900 km transmission line built 50 years ago and still running strong for the most part.
The cafes would not want that because guests are expected to leave and make room for new ones after some time. That’s also why they crank up the music in these places.
