LOL, yeah, happens to the best of us.

Think you're confusing 1-3MHz with 1MHz-3GHz. In the 1990's, chipsets were running in the 100's of MHz. The first 1Mhz chip was in the 1970's, the first commercial PC, the Altair 8800 used a 2MHz Intel 8080. The original IBM PC in 1981 released with a 4.77 MHz CPU. In 1995, the Intel P5 was running at 100MHz, and in 2000 AMD released the first 1 GHz CPU.

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.

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.

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.

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?

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.

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

>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.

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