  1. Re:It's passively cooled on US Tests Nuclear Power System To Sustain Astronauts On Mars (reuters.com) · · Score: 1

    I've heard about it long time ago. The lifetime of the reactor is at least 10 years and it's mostly limited by moving parts. There's also a possibility to use thermocouples to extend it even further, but this will drastically reduce the power. The amount of nuclear fuel is just several kilograms of highly-enriched uranium, but it's not going to burn completely before the reactor stops for good because of accumulating neutron poisons.

    This reactor is amazing - it's completely passive. It's self-regulated by thermal expansion of its fuel. There are no moving parts (apart from a heat engine), the reactor is started by removing one control rod and then it just runs on until fuel is exhausted.https://hardware.slashdot.org/story/18/01/18/2148243/us-tests-nuclear-power-system-to-sustain-astronauts-on-mars#

    There's not going to be a generic 3D "molecular printer" for a long, long time. For one thing, lots of interesting reactions require special conditions that won't sit well with generic "3D printing" stuff: heat, catalysts, pressure, nasty precursors.

    Actually it doesn't. It merely oscillates a bit between hard coal and lignite. The percentage of coal in power generation stays pretty much constant, with natural gas replacing nuclear. See here: http://energypost.eu/wp-conten...

    And given your reading comprehension you are fit to flip burgers in McDonalds. Notice the word "throughput"? Let me provide you with a dictionary definition: "the amount of material or items passing through a system or process". A typical road has the maximum throughput at 45 mph, if speeds are higher then the distances between cars are bigger and as a result _fewer_ cars in total can pass within a given time.

    A little bit. The best throughput per lane is a 3 lane road moving at 45 mph. More lanes and throughput per lane falls.

    VIOLA:
    Why, Salisbury must find his flesh and thought

    That Caesar and my goodly father's world;
    When I was heaven of presence and our fleets,
    We spare with hours, but cut thy council I am great,
    Murdered and by thy master's ready there
    My power to give thee but so much as hell:

  18. Ok. I keep offering this bet to conservatives. Right now my house is served only by Comcast. I bet you $10000 that in 2 years I won't get any new competition offering unmetered Internet at least at 50MBps speed. I can even make it easier - I bet that I won't get better performance than I have right now from Comcast. Deal?

    Before NN repeal the only way Comcast was able to get more profit was to build out the network, providing better speed and coverage. Now they also can raise the price for Internet content providers without investing in their network. Guess what is going to happen?

  19. Why is it rational? Repeal of the NN means that they actually don’t need to invest more, as they can extract bigger profit from existing infrastructure.
