    What change do you propose? Being born ultra rich?

    If you work hard and become a professional you can make 100-120k in your 30s. Maybe as much as 150 if you get lucky. Those jobs exist in places where rent is 50% take home and ownership is completely off the table.

    Do you suggest working a Denny’s in a rural area? Fuck that and fuck you.







  • There is 1.4E21 kg of water on Earth. 0.03% of hydrogen is deuterium, a suitable fusion fuel. H2O has an atomic mass of 18 and O has an atomic mass of 16, so Earth has 4.7E16 kg of deuterium readily centrifuged out of ocean water.

    D-D fusion converts about 0.1% of mass to energy (4 MeV / c^2 / 4 Daltons). E=mc^2. So we have 4.2E30 (420E28) Joules of fusion fuel ready for us on Earth. We used 2400 TWh of energy last year. If we used this amount indefinitely then we would have 485 billion years of fuel.

    Bonus: deuterium depletion would have virtually no environmental effect.








  • It does have a decent loop area in between the signal and return path and any flux passing through it will induce noise. This area is too small for 60 Hz, but there’s a lot of microwave crap that would get picked up. If there isn’t a low-pass analog filter before the next silicon junction then this RF EMI will get rectified down. If it’s a sufficiently bad situation then you’ll hear it. That’s why you can hear garbage when you put your phone right next to crappy computer speakers.
