Boston Dynamics Wildcat Can Gallop — No Strings Attached
Boston Dynamics has been making eye-catching (and sort of creepy) military-oriented robots for several years, and we've noted several times the Big Dog utility robot. The newest creation is the untethered, gas-powered Wildcat; this is definitely not something I want chasing after me. (Not as fast as the previous, tethered version — yet.)
Kinda reminds me of my ex, actually. Fast, noisy, high maintenance.
Faster! Faster! Faster would be better!
...really smart people creating things - "war machines" to be blunt - that will wind up killing someone on some battlefield somewhere (probably the Middle East and North Africa). If BD were creating robotic devices for peaceful purposes - a "dog" for the blind, a robot that can do some old lady's shopping for her - then I would be applauding the effort/brilliance on display here. But building clever war machines? Sorry, but this isn't something intelligent, conscientious people would even dream of working on. So its "boo combat robots" for Boston Dynamics from me, rather than "yay cool robots"... My 2 Cents. Feel free to disagree...
Why did the chicken cross the road? Because Elon Musk put an AI chip in its head.
I really wish people could understand that. the small nuclear reactors could power a laptop or two for 30 years but could never produce enough electricity fast enough to run a clothes dryer for one run.
You know, people would be more likely to understand that if we could stop this business of calling RTGs "reactors". The concept of a "reactor" (whether chemical, biological, or nuclear) is usually that it provides some form of support for a reaction to take place which otherwise would not take place, or would only take place in a different, less useful/safe/something way.
Radioactive decay is not in any meaningful sense a "reaction", and would be happening to the Pu (or other "fuel", if you're using something different) whether or not it's in the RTG, at essentially the same rate, generating the same amount of heat. The only thing the RTG does is feed the decay heat through a heat engine (typically a Seebeck device, but there's some work using a Stirling engine), to extract some work from the heat flow -- no reaction, so it's no reactor.
Ordinarily, I'd call such a distinction as this useless pedantry, and not engage in it, but you're correct that there's a problem with people being ignorant about RTGs and thinking they have capabilities they don't -- and since I'm convinced the general habit of calling RTGs "nuclear reactors" contributes to this, I think it's a distinction worth making.
