If the price and maintenance is right, otherwise cheap and maintenance free solar pv + heat pump will outperform this. Solar thermal panels are a maintenance headache, but perhaps these will work better by not getting too hot, they still have to make it robust to freezing temperature problems.

e+th, but pretty nice if they can keep the price low

"works in space" I guess

Sofa embedded refrigerator. Sofakingcool.

There's no controversy, it's really a bad idea and everyone knows that. It's almost like the flat earth idea that keep getting pushed onto mainstream

Didn't you read the terms of service? Any complaint may result in immediate cancellation without recourse.

if this is something that works by injecting again (not saying it is), then it's exactly what pharma companies want, life extension by subscription. Don't get behind your payments.

Vacuum is the ultimate insulator. Wonder for how long it will retain a high vacuum state. This could be applied to hot water cylinders too.

yeah, lol, and here's just the thing to launch humans from a giant rail gun (slightly tweaked Julius Verne original idea btw):

"A protein found in human cells has been repurposed to make a material that reforms when it is struck by a projectile, capturing the object intact"

"When something hits the gel, the energy unfolds the modified talin switches rather than being converted to heat, as is the case with existing materials, says Goult. Silica gels filled with air, or aerogels, have previously been used to capture small objects in space, but these heat up on impact, potentially damaging both themselves and the captured material."

Perfect airbag to cushion the 20 G's hitting your meatbag, lol

> I also think eventually we won't rely on combustion to reach the atmosphere. My thoughts were centrifugal force or some kind of magnetic accelerator.

I like the space elevator (easy on the Moon and even Mars) for Earth there's also laser launcher/accelerator, also doubles as wicked laser gun.

Yeah, lol. When you're already in space electricity driven engines do work, like Ion thruster, but for breaking away from Earth's gravity we still need to figure out some new physics, not totally impossible.

Hmm cobalt, this is not coming cheap, SpaceX's starship made of steel certainly much cheaper.

Neptune looks beautiful even with so little pixels

Biggest one hit Canada IIRC

Additional bonus over HVAC: underground HVDC is better shielded from EMP/sun flair.

Yes, just replacing dirty hydrogen will take a very long time and effort. Burning green H2 that could replace gray H2 in chemical processes is criminal at this stage.

I agree, only green H2 from renewables should be considered together with fuel cells that produce waste heat but also electricity to drive heat pumps or supplement the local grid when renewables are short.

Using H2 in a boiler is such a waste and produces NOx, total non-starter.

OTOH having distributed electricity generation with Fuel Cells fed by green H2 could be valuable for grid resilience and to lower total costs of the system and district/residential heating is just an add-on benefit at that point.

The natural gas crisis, be it price/geopolitical or pollution wise, is prompting this. We need cheap fertilizers from green H2 and water desalination.

McDonald's enters the chat serving pink slimme

if renewables are constrained/curtailed because of transmission limit, then increasing that limit will be powering homes with cheaper energy.

5 kW turbine for a 3 sqm area? Apart from sporadic and localized gale winds I don't see much potential wind power to harvest in just 3sqm, much less in the kW range. I'm very skeptical of these claims.

That's great news, but historical data in https://app.electricitymaps.com/zone/GR

shows a different picture
