   Of all the things Google has killed, I really miss Notebook. It was nimble and lightweight, while Docs is bloated and drags my old machine down (not to mention my crappy internet connection). Around 2001, Google had a nifty toll free phone

   Maybe. At high altitudes, the ions can be accelerated to much higher velocities before losing energy due to molecular collisions. Higher acceleration of the working fluid, more thrust and higher efficiencies. Much like a rocket. There i

   At this point, there are no long distance electric trains in the US. Odd, it seems like it would be mutually beneficial to have the electric grid run on rail right of way and be used to power trains.

   Hydrogen is a great lifting gas, but because the molecule is so small, it leaks out easily.

   I guess it depends on what you mean by "ham radio". Here's a tiny surface mount transmitter that is barely more than a gram and operates on amateur frequencies. https://www.youtube.com/watch?v=wMkaN21K5S0 Ger

   AmSat has some good articles for getting started with satellites: https://www.amsat.org/introduction-to-working-amateur-satell... Moonbounce is challenging even for experienced hams.

    That would be a logical assumption, wouldn't it.

    I had no idea retrocomputer kits were a thing. Can you provide any links? I'd love to learn more.

    > Outside some hill-climb racing it seems most innovation is explicitly forbidden... Don't forget about land speed racing, which is quickly gaining popularity on repurposed air strips. About the only rules are related to safety, t

    That is indeed a big factor, but another important factor is that the bones of children are less brittle than adults. I retired from being an EMT last year and it's amazing what kids literally bounce back from while adults break a hip

    Public perception has been poisoned with regard to nuclear fission. Changing public perception is expensive.

    Very good point. Doubtless though, if it ever achieves technical viability, fusion will have a niche, because not all applications require economic viability. Can't beat the energy density it provides, either. Would be great for out

    Progress! First, it was always 30 years away, then 15 years, now it's down to 10 years. Not sure how to determine the asymptote, but it'll doubtless happen with the Singularity. Links: Why Nuclear Fusion Is Always 30 Years Away
