Usually it's microwaves. See the Department of Energy Infographic - https://www.energy.gov/articles/space-based-solar-power

Microwaves are DEADLY!! Not sure that’s a good idea ☠️

I didn't think you were being serious but looking at your post history, you're being very serious. 😬

You deny that microwaves are dangerous!? A microwave from space won’t be 100% effective. Energy will be lost to the atmosphere! Talk about Global Warming!!

The wavelength they're proposing usage of is significantly large enough to make the amount of energy negligible to any life in the path of the beam. The receiver dish is between 3-10km in diameter, and if you were to walk out on the dish during the night you would be exposed to about half the amount of radiation as you would walking around in the midday sun. So no, not very dangerous. You do realize that the Sun bombards us with massive amounts of microwave radiation already? This is simply enhancing and focusing that energy to a point where we can more efficiently collect it 24/7 instead of simply during the daylight. And the loss to the atmosphere is estimated to about about 1.5-2%. We're talking miniscule amounts compared to the energy the sun pours into our atmosphere. Not to mention, you would also be reducing consumption of fossil fuels by a significant amount, thus actually overall reducing the amount of energy added to the atmosphere. Assuming 2% of a 30GW space solar energy plant, you're looking at 600MW of energy being lost into the atmostphere. To produce 30GW of energy on fossil fuels, you're dumping about 70,000 metric tonnes of carbon dioxide into the atmosphere each year. CO2 is dangerous in the atmosphere because it happens to vibrate and absorb energy in the Infared spectrum, not Microwave spectrum. Microwaves at the energy level proposed here would not excite water molecules or CO2 molecules in the atmosphere, thus it would not increase the thermal energy in the atmosphere by any significant amount.

I’m sure they make it SAFE!! I’m talking about the atmosphere and how microwaves travel through it causing it to cause Climate Change ☠️

Did you not read what I wrote? Infared causes heating of the atmosphere, not microwaves. Wrong frequency.

Microwaves transfer their energy to all particles they strike! Otherwise all energy would already be transmitted by it now!

No, they don’t. Electromagnetic waves don’t work like that. Light behaves as a particle wave. It doesn’t interact with all matter, and the energy transfer greatly depends on the wavelength of light and the energy level of the matter. CO2 happens to be easily excited by Infared light, but microwaves have a longer wavelength and are really poor at transferring energy into CO2 gas. https://www.livescience.com/50259-microwaves.html
Wanna know how to prove it? Go turn on your microwave for 2 mins with a small glass of water inside. Did the air temperature inside rise at all? Only the water inside is heated because the wavelength of a microwave is too large to transfer the energy to most gasses. There are a few noble gasses like Neon that would be excited if they were in there, but CO2 isn’t one of them, while it is the primary gas responsible for global temperature increase.

You’re right, and the sun’s electromagnetic energy doesn’t cause changes in the earths atmosphere! The Northern Lights is just fireworks 🤣
seiggy t1_ixhmke0 wrote
You do realize you're proving me right with that statement. The Northern Lights aren't caused by EM Radiation, they're caused by charged electrons in Solar Wind, not by Microwaves. EM Radiation are photons and uncharged fundamental particles, not high energy electrons. https://www.nature.com/articles/s41467-021-23377-5.epdf?sharing_token=Q0rjm5h2j_KavQboPe5r0NRgN0jAjWel9jnR3ZoTv0Nipe223V5hYGHe-RFuAQXUauChqVoyT7zITbpx_l9I4d9y3fMVLy0n3sVw5SJRoc_II7uBqXU-SzFM3JaTK6_kNmWDs_aEyfCQVLoWqqw15NsYjbFSXvak0yfuKrH76x8%3D
Are we going to just be going thru a full particle physics lecture by the end of this?

Did you realize I’m proving that every type of energy has an effect on our atmosphere! Microwave transmissions will cause climate change! They’ll hear the water droplets in the atmosphere causing the temperature to rise!
seiggy t1_ixi0ggz wrote
You do realize that the whole point of these projects are to replace the existing fossil fuel plants. Not replace things like Hydroelectric, wind, solar, or nuclear power which doesn't add greenhouse gasses to the atmosphere. So by reducing the greenhouse gasses, Microwave or Laser based satellite solar plants would reduce the global climate change impact of humanity, not increase it. The amount of energy added to the atmosphere from a Microwave or Laser based solar plant is significantly less than the energy added because of the CO2 that a fossil fuel based plant adds to the atmosphere. Did you not read my post 3 topics ago? That's the entire point I've been making is that it's a net loss of energy compared to today, thus not increasing global temperatures.

Microwave energy heats water in the atmosphere! That percent doesn’t change much every year. Those issues have other solutions.
seiggy t1_ixi2pgd wrote
Right, so why haven't we seen a massive increase in global warming from the absolutely massive amount of microwave radiation we already produce from cell phone towers, wifi, bluetooth devices, and other modern wireless tech? Oh yeah, because the wavelength is too large to cause such energy transfer. It's the wavelength we use specifically because it's safe, low energy, and passes thru most matter easily without energy loss.
barzbub t1_ixi4qdu wrote
Haven’t we!? Or they’re blaming one cause and not another to misinform the public!?
seiggy t1_ixi6xgt wrote
Ah, so you're one of those. CO2 is the primary greenhouse gas that has caused accelerated global climate change. All of the science agrees and points to it. Only nutcase conspiracy theorist with no actual evidence claims anything else. If we're going to talk conspiracy theories and wild baseless claims without facts and science to back it up, I'm done explaining things to you.
