  • I’d argue that it wasn’t really “net-positive”. Certainly it was a positive energy gain, but it took way more energy to create the fusion than just the input energy. There is a ton of efficiency losses to create the input energy, which is defined by the energy in the laser beam that triggers the fusion. A lot of energy is also used to maintain confinement during the reaction.

    I would like the term net positive to be more inclusive of all of the recurring energy used to support the fusion. It’s fair to not include the energy used to construct the machines, but anything that would need to be put in to a fusion plant each reaction to get out energy should be considered.














  • Right? They portray it as a problem rather than as a sign that cars have finally hit the point where they’re not dramatically improving in reliability, safety, and efficiency nearly as quickly anymore. That is not a bad thing really.

    For capitalists, a healthy used market is a bad thing. Captial requires continuous production to make returns on itself.

    One of the few things anymore that has a really strong used market besides cars is housing, so the capitalists switched their investment from developing new housing to vacuuming up the existing stock to instead collect rent and increase the value of their portfolio.




  • There are also tons of machines and tools made to work in inches. As more things are becoming computer controlled, it’s easier to convert between inch and mm on the fly, but every drill bit, end mill, and tool holder for the manual mill in my company’s shop is in inch.

    I’m also gonna disagree with you on the 12 better than 10 front. Just use a calculator if you can’t do it in your head and round to the nearest mm. I bet you’ll learn what 10/6 and 10/3 are faster than 12/5 too.
