The intense heat energy beneath the Earth's crust is virtually limitless, but for most of history geothermal had always been an underrated and ignored power source mainly due to location problems (you have to build them next to volcanoes). And drilling of course becomes more expensive the more you dig deeper due to the bits wearing out while the rock becomes more dense. But "deep geothermal" technologies like Quaise millimeter-wave or Plasmabit plan to use direct-energy drilling to melt/vitrify this highly dense rock and dig deeper than ever before, potentially reaching such depths in the Earth where the heat is so intense it can turn water/steam into a supercritical state. This in theory can make geothermal available all over the world.
But I'm rather sceptical. You can dig that deep, but with the kilometer-long pipes needed, won't the supercritical water lose a lot of its energy as it comes back to the surface? https://www.youtube.com/watch?v=Q2kRzKEJW4o https://www.youtube.com/watch?v=cacaUwrIrkY
Might have been exposed to a bit of Selenium Dilfuside (shampoo), in my eyes, been hurting ever since that but oddly no shampoo got in my eyes I think.
Didn't rinse eyes for like one hour, am I going to go blind?
Problems from a math competition for Russian 5th graders
- Can the digits 1 through 9 be arranged to form a number such that between all pairs of digits differing by 1 there are an odd number of other digits?
- Is there a square integer that starts with 123456789?
- A country has four types of bills, worth $1, $2, $5 and $10. Prove that if you have exactly $400 then you can pay someone else exactly $300.
- Prove that if two positive integers sum to 770, then 770 does not divide their product.
I love life. I have a good job and good health. My only worry is aging.
I try to extend my healthy life. I eat a good diet and I work with a personal trainer. I go to doctor whenever I need to. I have a good lifestyle because that is all that official medicine can recommend.
But I'm 28 now. And official medicine is too slow.
That brings me to stem cell therapy. Maybe I'm delusional, but from what I've researched, it's the closest I could have to the elixir of life.
The good thing: the laws are more lax, and it's much cheaper outside the US. I think with about $10k, I could pay for a whole round trip to South America to get embryonic stem cell therapy. If I space my trips every 3 years, that means I just have to set aside ~$300 a month, which I can definitely do.
How long might this extend my life (or health), if I keep getting these treatments?
