Plans to beam solar generated electricity wirelessly from space to homes – BBC News
Space bosses are to investigate whether electricity could be beamed wirelessly from space into millions of homes.
The European Space Agency will this week likely approve a three-year study to see if having huge solar farms in space could work and be cost effective.
The eventual aim is to have giant satellites in orbit, each able to generate the same amount of electricity as a power station.
ESA’s governing council is to consider the idea at its Paris HQ on Tuesday.

Much of western Europe is under the most extreme red heat alerts – meaning there’s a potential risk to life.
France, Spain and Italy have been hardest hit by the heatwave so far.
But why is it so hot? What can you do to stay safe? And is El Nino to blame?
We answer some of your most asked questions about the heatwave sweeping Europe with our climate and health correspondents.
We’re also joined by our teams in Paris, Madrid and the south of France.

Tens of thousands of organisations have been caught out by a computer virus called WannaCry. The malicious software locks data away and demands a payment of up to $300 (£230) a time before it will restore scrambled files. In the UK, many hospitals fell victim and some health organisations diverted ambulances and cancelled non-essential services as they sought to contain and clean up the infection. Infections in more than 99 nations are being reported by security firms. It appears that the hardest hit are Russia and Spain.

A year ago, artificial intelligence was being sold as something close to science fiction — a technology that could transform society, cure disease, even reshape the global economy.
Today, the tone is changing. The companies leading the revolution are racing to the stock market — chasing billions in investment — while quietly confronting a much harder reality: AI is expensive, unpredictable, and far from profitable.
At the same time, some of the very people building this technology are warning we may be going too fast — even calling for a global pause.
And beyond Silicon Valley, a different story is emerging: growing public anxiety, political backlash, and the rise of what some are calling anti-AI populism.
So is AI entering its most pivotal moment yet — caught between financial pressure, technological risk, and political resistance?
AI Decoded Presenter Christian Fraser is joined by Financial Times AI Editor Madhumita Murgia, Thematic Strategist at Deutsche Bank Research Adrian Cox and Richard Coffin, Host of popular investing podcast ‘ The Plain Bagel’.

If the suceed eith this we are one step closer to becoming a fully orbital species meaning we could then make all C02 producing manufacturing into orbit which would drastically reduce our pollution and it might happen just in time for us to halt climate chsnge 🤞

I asked ChatGPT:
"If a high-energy beam of microwaves were to suddenly hit Earth's atmosphere, several effects could occur, depending on the intensity and frequency of the microwaves. Microwaves are a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of radio waves. Here are some potential effects:
Heating of the Atmosphere: Microwaves are known for their ability to heat substances that absorb them. If the intensity of the microwaves is high enough, it could lead to the heating of the Earth's atmosphere. This could have various consequences, including changes in atmospheric pressure and density.
Ionization: Extremely high-energy microwaves have the potential to ionize molecules in the atmosphere, meaning they could strip electrons from atoms and create charged particles. This could lead to the formation of a plasma, which could affect radio wave propagation and communication systems.
Interference with Electronic Devices: Microwaves can interfere with electronic devices and communication systems. If the intensity of the microwave beam is strong enough, it could disrupt or damage electronic equipment on the Earth's surface.
Effects on Weather Patterns: Intense microwaves could potentially influence weather patterns by affecting the distribution of energy in the atmosphere. This could lead to changes in temperature, pressure, and wind patterns.
Impact on Living Organisms: High-energy microwaves can have biological effects on living organisms. The absorption of microwaves by living tissues can lead to heating, which may cause damage to cells and tissues. The extent of the impact would depend on factors such as the duration and intensity of exposure.
It's important to note that the specifics of the effects would depend on the characteristics of the microwave beam, such as its frequency, power, and duration. In reality, deliberately directing a high-energy microwave beam at Earth would raise ethical, legal, and safety concerns. The consequences would likely be highly undesirable and could have wide-ranging impacts on the environment, technology, and living organisms."

Oh…
So NOT a conspiracy theory then?
An actual concept thats been in existence for decades and is now being trialed by China and Brazil.
I don't suppose this could be weaponized?
Could it?

Just like my invention but I used different and cheaper technology but mine can also transfer data and decentralize power.
