  • Good idea but sadly not feasible

    Relevant part (credit to [deleted] and u/chiagod):

    Assuming D-T fusion, a single fusion event releases a 14.1MeV neutron and a 3.5MeV helium nucleus. Assuming you can absorb all this energy and you’ve got an efficient heat engine setup at around 50%, you’ll get about 1.5x10^-12 J per fusion, so for a 1GW output you’ll need 6.67x10^20 fusions per second. Say you have 1TWe (electric output) worth of fusion reactors worldwide (about half of current electricity generation), then you’re producing 1000 times as much helium, or 6.67x10^23 atoms per second. About a mole each second, or 4 grams. This works out to 126 tons of helium a year, or about 1000m^3 per year of liquid helium. The US strategic helium reserve had a peak volume of about a billion m^3 . World consumption of helium is measured in tens of millions of m^3 per year so you’d be short by several orders of magnitude in the best case.






    • MSF provide health services and are around 80% efficient (20% of your donation goes to overhead). I’m not sure if they make it easy to earmark a donation to Gaza.
    • UNICEF does more infrastructure projects, but have around 30% overhead.

    If you really want to maximize your impact, check if your employer or professional association have donation matching for various large charities.

    There are obviously many more charities - these are two that I believe have the highest chances of actually reaching civilians in Gaza and not being diverted.



  • Also that in order to exploit this it requires an active man in the middle. Which requires any of the following:

    • Reverse proxy hijack/NAT hijack - from a compromised machine near the server
    • BGP hijack - stealing traffic to the real IP
    • DNS hijack - stealing traffic to send to a different IP
    • Malicious/compromised network transit
    • Local network gateway control
    • WAP poisoning - wifi roaming is designed really well so this is actually easier than it sounds.

    Almost all of those have decent mitigations like 801.x and BGP monitoring. The best mitigation is that you can just change your client config to disable those ciphersuites though.
