I do like the microwave energy transmission idea. I seem to recall that https://www.quaise.energy got their first test device from the Air Force in Albuquerque that was experimenting with the devices for crowd control. Think of it! 5G that has a high-power beam forming mode that could disable pedestrians at any location!

Conventional drilling methods are very mature, but still have difficulty drilling through very deep,very hard and hot rocks for geothermal, nuclear waste entombment and oil and gas applications.This project demonstrated the capabilities of utilizing only high energy beams to drill such rocks,commonly called ‘Direct Energy Drilling’, which has been the dream of industry since the ... www.osti.gov [https://d19xrwp2bu8dt3.cloudfront.net/general/Quaise-link-img1.png]<https://www.quaise.energy/> Quaise Energy<https://www.quaise.energy/> Quaise is an energy company unlocking geothermal energy for the world population through millimeter wave drilling technology. www.quaise.energy ________________________________ From: Friam <[email protected]> on behalf of Steve Smith <[email protected]> Sent: Friday, December 16, 2022 11:38 AM To: [email protected] <[email protected]> Subject: Re: [FRIAM] technical notes on fusion announcement On 12/16/22 10:56 AM, cody dooderson wrote: I had never heard of a transatlantic power grid.

Of course, you raise #3, so it would be a target for sabotage like with Nordstream. It would be nice to think there are things just to valuable to destroy, but probably there are no such things. ________________________________ From: Friam <[email protected]<mailto:[email protected]>> on behalf of Sarbajit Roy <[email protected]<mailto:[email protected]>> Sent: Friday, December 16, 2022 12:01 AM To: The Friday Morning Applied Complexity Coffee Group <[email protected]<mailto:[email protected]>> Subject: Re: [FRIAM] technical notes on fusion announcement What you are missing includes 1) Disposal of long term hazardous nuclear waste. 2) Problems in maintaining / decommissioning ol older nuclear fission plants 3) Examples like we are seeing Ukraine's nuclear plants caught up in a war.

We want less carbons because the planet is on f'n fire<https://www.youtube.com/watch?v=IFgBFYkBZ6E> . As far as I know humans (in the very least) accelerated climate change. Ie we made this mess clean it up. ok fair so far I'm following. So uh why not just start with fission (breeders) ? Why not also put as much money into matter/anti matter as well as fusion? We can make minute amounts of antimatter in massive collider. I'd think something who's by product are xrays gamma and some other stuff with a lot of energy created would be a massive honney pot the department of energy would pursue as well. I know the answer to fission (sadly) is NIMBY. (yes but it's a lot cleaner and safer than oil and coal I say) I don't know why we haven't looked at other things as well What I'm saying is fusion has been humans icarus wings with it being just arround the corner for decades. while matter/anti matter is (sort of) here. Fission is here. Want zero carbons? cool! so why not build out a ton of reactors we already can do. Or am I missing something?

My understanding is that D-T fusion occurs at a lower temperature than D-D but that once fusion commences (starting with D-T), both D-T and D-D reactions occurring in similar amounts. In laser-driven ICF (as with NIF) I believe the ratio of D/T is nominally 50/50 though it would seem to make sense to have a higher T to D ratio but most references I see imply equal portions. An equal number of D-D and D-T reactions would seem to consume D more quickly, though as that commences, the D/T ratio would go down, making D-T reactions (yet) more likely... tricky business, no wonder it has taken decades to get to this point?
