I think the costs of fission were well understood in 1999. The critics he was responding to were all taking the position that fusion would not be competitive with fission. Fusion is better in terms of proliferation issues, long-term radioa

Based on YBCO prices from a few years ago, the estitmate was $200M in material cost for the magnets of a 200MW reactor, not an outrageous amount considering all of the other costs. The real issue was getting the construction cost of the ma

Yes. The only number I could find for a Uranium PWR core was 69MW/m^3. Lidsky said in 1983 that "the power density is only one-tenth as large" (fusion vs. fission) so I assume this is what he was talking about. I only want

There are no "magnets" at this point, so not sure what he is talking about. Basically they are building up HTS Twisted Stacked-Tape Cables (TSTC) and they plan on building their first full-size prototype coil in 2020. Current tes

How about one of the authors talking about a credit-card sized device supplying 100 watts to quad-coptors using liquid fuel and staying airborn for 16+ hours. ( https://youtu.be/lDxJsa8miNQ?t=3202 )

The solar panel market is dominated by cheap silicon wafer based production from China. This research involves uses of higher efficiency PV in other markets. Thermophotovoltaics have applications in hybrid cars, drones, and cogeneration o

The device is mentioned in this talk ( https://youtu.be/lDxJsa8miNQ?t=3105 ) and provides 1kW of electricity and about 1kW worth of "waste" heat used for hot water. The key idea is that the amount of light would be

Eli Yablonovitch's company, Alta Devices, manufactures a thin film high efficiency PV cell but they can't compete right now against cheap Chinese silicon wafer cells in the solar panel market, so they are focusing on niche markets

Kardashev looked at the physics in 1964 and said that civilizations that don't grow fast enough (energy use requiring expansion to other planets) risk planetary catastrophes and would not be expected to survive many thousands of years.

A better analogy is that one of your star players (ice sheet stability) maybe isn't as good as you thought he was (turns out snow accumulation > surface melting is not the whole picture) and has some major potential weaknesses (mari

Regarding your radiating tower idea, wouldn't the radiation need to be in the visible light spectrum in order to avoid the greenhouse effect? Probably better to just do carbon capture to reset the greenhouse gas thermostat. But that

Don't pay the $10 monthly fee to rent a Comcast cable modem and instead buy your own cable modem and router for $110. Side benefit: no extraneous Xfinity AP clogging up your precious wifi bandwidth.

He said "apartment 5 is often more crowded than suburb 2.4" 2.4 is unusable in an apartment building because the range is so great. I live in a 3 unit so I am happy with my 5 Ghz but in a very dense building I could see problems.

There are effectively three 2.4 GHz channels and about six 5 GHz channels, but because the range of 5 GHz is so much smaller you should be able to find on open 5 GHz channel even in the densest, tech heavy, apartment building. As the author

Realtors know they are responsible for representations so they are very careful about limiting their knowledge of the property to exactly what the owners have stated on the listing. Playing dumb is really important to being a listing broke
