  • There is one variant called Magnetized Target Fusion that kinda-sorta works like this, where the “cylinders” are made of liquid Lithium. On each “stroke” of the engine:

    • A rotating chamber of liquid Lithium is spun to make a cylinder of liquid metal
    • 500 pistons situated at the site of each spinning Li pool are precisely synchronized to push the liquid metal inward, turning it into a sphere
    • Fusion fuel (H plasma) is injected into the middle
    • The intense pressure forces the fuel to undergo fusion, pushing the pistons back out and distorting the Lithium back into a cylinder

  • Right. Traditional projection TVs have reflective screens - your eyes are getting photons that have bounced off of something already, making them less bright and lower contrast. Thing is still an emissive screen tho. The white photons from the projector are filtered by the LCD but then head right out to your eyes without bouncing off of anything else. This keeps the color gamut very high, and the projector only lighting up the pixels that need to be lit keeps the contrast very high (like an oLED)

    My desk is littered with post-it notes and papers, as the act of writing something down is usually what helps to “lock” it into my memory for a time. Unfortunately due to the ridiculous number of to-dos I usually have at any given time it makes me look like some kind of crazy note-hoarder.
