No need for such things Bas, the way the earth is heating u, the oceans boiling, and the Co2 increasing, conditions that cause frost will just not occur.Imagine being able to stop things from frosting up ? This a potential new use for graphene.
Farewell frost! New surface prevents frost without heat
Optimized surface prevents 100% of frost formation on flat areas for a week
Date: October 30, 2024 Source: Northwestern University
Summary: In a new study, researchers discovered that tweaking the texture of any surface and adding a thin layer of graphene oxide prevents 100% of frost from forming on surfaces for one week or potentially even longer. This is 1,000 times longer than current, state-of-the-art anti-frosting surfaces. Share:
Someday, people might finally say goodbye to defrosting the freezer or scraping frost off slippery surfaces. Northwestern University engineers have developed a new strategy that prevents frost formation before it begins.
In a new study, the researchers discovered that tweaking the texture of any surface and adding a thin layer of graphene oxide prevents 100% of frost from forming on surfaces for one week or potentially even longer. This is 1,000 times longer than current, state-of-the-art anti-frosting surfaces.
As an added bonus, the new scalable surface design also is resistant to cracks, scratches and contamination.
By incorporating the textured surface into infrastructure, the researchers imagine companies and government agencies could save billions of dollars per year in averted maintenance costs and energy inefficiencies.
The research will be published on Wednesday (Oct. 30) in the journal Science Advances.
"Unwanted frost accumulation is a major concern across industrial, residential and government sectors," said Northwestern's Kyoo-Chul Kenneth Park, who led the study. "For example, the 2021 power crisis in Texas cost $195 billion in damages, resulting directly from frost, ice and extreme cold conditions for more than 160 hours. Thus, it is critical to develop anti-frosting techniques, which are robust for long periods of time in extreme environmental conditions. It is also necessary to develop anti-frosting methods which are easy to fabricate and implement. We designed our hybrid anti-frosting technique with all of these needs in mind. It can prevent frosting for potentially weeks at a time and is scalable, durable and easily fabricated through 3D printing."

Good stuff Sir Rumpole. ExcitingThe search for life on Jupiter's moon Europa.
That is a seriously, seriously good story. Making hydrogen storage and transport cheap and simple. Very promising indeed.So your h2 can now be carried and use like oil based product...Canadian Startup Aims to Make Hydrogen an Everyday Fuel

Less control and money for the RE lobby, less new car truck and actually doable vs current battery vision
Yeah it keeps popping up like orbital solar farms and the like.This is a project I have read about since I was a boy.
It seems to be revived every decade or so, gets a run for while, then quietly disappears.

Money is no problem if we can fund windmills or Ukraine war by the dozen of billions, let alone Ndis in a 30 million citizens countryYeah it keeps popping up like orbital solar farms and the like.
Nice if they can happen, but where's the money coming from?
Yea, its a science fiction trope.Yeah it keeps popping up like orbital solar farms and the like.

The cable would just be an elevatorYea, its a science fiction trope.
Lot of engineering challenges. New materials are starting to make it more feasible but honestly, how do you make a rope that doesn't weigh too much, doesn't stretch too much. can handle incredible shear forces, cold temperatures, radiation, that doesn't pull down the satellite?
Then you have to get the lift up the cable, how do you grip the cable, how does the cable get pulled and how do you handle the torsion?
What happens if the cable snaps?
Maybe the place for it would be the north pole.
I think we haven't got the technology yet or even have something on the horizon though the new nanotechnologies are giving hope.
"The US government has already shifted some communications to Starlink’s encrypted government service, Starshield. Although satellites are not immune to hacking either, Starlink’s equipment is manufactured in the United States, a rarity in the globalised telecommunications industry, providing less opportunity for a foreign hacker to intercept and tamper with gear.Based on stats from

the mass of Starlink satellites in orbit is over 2600 tons - almost 6 times the mass of the ISS - and it is growing quickly.

"Aside from its consumer internet service, Starlink is building out a next-generation network of surveillance satellites for government use, jostling with more established players such as Maxar Technologies and Planet Labs. Industry experts say the company is on track to build the world’s first system able to monitor all spots on Earth continuously in near real-time, revolutionising reconnaissance.
