if the measurement time is short enough, (<1us capturing at 60 fps), the probability of interaction is low even with large number of cameras. Even then, some temporal filtering and intelligent time offsetting to separate signals, can usu

It only matters if you need physically accurate data - ie if your brain can't process the multi path error and correct for it. A bat sees in multi path error and has no problem with it. I assume a machine vision system can learn to per

- there is waste, it's just shorter lived than fission waste and lower in quantity. The expectation is that fusion reactors will have to be regulated in almost exactly the same way as fission reactors because they are nuclear sites, wi

Since the reactors would ostensibly be continuously operating, the danger is the same. 10+ year half life is about as dangerous as 10000 years because you are always generating the waste.

The materials listed on the Wikipedia page and used by the Russians are not practical for large scale use. It's simply too dangerous to have that much weapons grade material or bone seeking material out in the wild. Some isotopes are b

The most convenient decay source is Plutonium-238 because it does not produce any gammas during the decay which would require lots and lots of shielding to protect people. It has long half life of 87 years so a reduction in power of roughly

That's right. You have to have a society with enough moral fiber that it self-polices and restrains itself almost down to the individual level.

You mean crazy dangerous. At that power density, everything has to work for this thing to not meltdown.

The ham itself will protect it, wrapped in Aluminum foil or even a hemp bag for shipping. The packaging is simply an artifact of people not wanting to buy a whole ham and wanting it presliced, which is perhaps an artifact of the fact that m

The fetus would probably not have3 survived. You can't just make the brain bigger and expect everything else to work out. Example problems: skull too small, eyes and everything around the brain would have to be reconfigured, heart&#x2F

90% protection... Let's see what this really means - because I'm pretty sure we already have something on order of 80+% protection without a vaccine. I'd like to see % protection vs age.

also they used a strange control system. No control rods. Instead they moved the whole core up and down to change reactivity. wtf?

Seems like they used a sodium coolant - great thermal properties as it allows for atmospheric pressure loop. But sodium introduces the chemical hazard and all the associated maintenance and materials woes and accident scenarios. Also, the p

I don't think they're necessarily chasing grid power at first anyway. They seem positioned to tackle mass market electricity last, after addressing smaller higher price markets.

I highly recommend HBO's Chernobyl. Explains a lot this stuff. Basically, as a nuclear reactor operates, it is turning the Uranium into lots of other stuff. One component of this other stuff is Xenon-135, which absorbs neutrons and bas

Seems like their claim to "Ultra Safe" is actually merited based on a first principles look at the power density. They claim 1.24 W/cm^3 versus 20-40 W/cm^3 in normal reactors. The high power densities mean you have to b

Two interesting things to see here, of many. They are really planning the sites to be temporary compared to the solar/wind/ and other industrial power plants that have little or no plan for returning their sites to the original vi
