  • The US has laws that bans paying for blood, but they can pay for plasma. All healthcare in the US is a for profit venture.

    If you donate blood in the US, you are the only one in that process who is making a donation. Every other organization in the chain between your donation and the patient who receives it will add a markup for their own profit.

    Organ donations work the same way. If you get killed by a car, and your heart is used to save someone’s life, they will be charged nearly two million dollars for the operation. Not only does your next of kin not get a cut of that two million, your estate will still get a bill for whatever treatment failed to save your life.

    I can think of little that is more unethical than being the only one donating. Plasma is better because the donors are paid. If healthcare is for profit, at minimum the profits should go both ways. Plasma is the one time it does.





  • Get an old color laser printer, that is not aimed at the home market. Get whatever boring printer box your local library has. Toner stores very well, and it takes almost a decade for a normal person to print an office sized amount of toner.

    To do that you will need a separate scanner. Most desktop printer/scanners are aimed at home users where they do much more of the, “cannot scan low magenta.”





  • Going around the earth in 3 hours would require you to travel at 11 times the speed of sound, and that is without including the time it would take to accelerate or slow down.

    The concorde flew at a maximum speed of twice the speed of sound. It would take the concorde 18h30m to fly around the world if it had enough fuel to do it.

    Supersonic travel has some major issues. It takes a huge amount of energy to go that fast. Concorde could only cross the atlantic ocean, because it didn’t have enough fuel to cross the pacific. The other issue is sonic booms, which means you can’t fly supersonic over populated areas, like land.

    Maglevs have the same issue as all other high-speed overland transport, it requires expensive infrastructure to be built the entire route. The faster you want to go, the flatter, smoother and more expensive the track will be to build.

    Supersonic air is more plausible as it only requires a faster airplane. With wealth inequality, there are rich people who can afford their own supersonic plane, but an infrastructure project to build a global maglev network is far more expensive than that.
