  1. Re:It's just too expensive on Westinghouse Files For Bankruptcy, In Blow To Nuclear Power (reuters.com) · · Score: 1

    Fusion power is also fission power. All current fusion technologies involve He3 or tritium, but of which are fission byproducts created by bombarding lithium with neutrons. The current thinking is to place lithium in the fusion reactors to soak up the neutrons and produce heat and fuel, effectively making them hybrid fission / fusion reactors.

    You may be better off without the option.

    What if the options look like this:

    You can have unlimited use a self-digging shovel today for $20,000. A year from now, you have also have unlimited use of a self-digging shovel for $20,000.

    Or:

    You cannot have a self-digging shovel today. A year from now, you can have a self-digging shovel for $5,000.

    Which is the better option? The answer really depends on your needs.

    Uhh. No. They do not work that way.

    Have you actually used a DVD or Blu-Ray disc? You stick the disc in, watch several minutes of ads and warnings, and eventually get to a menu that allows the movie to play. It is annoying and it is one of the reasons I quit buying them.

    You have to "decarbonize" limestone (CaCO3) to Calcium Oxide (CaO) to make cement. You _cannot_ make cement without producing a lot of carbon dioxide, even if your energy source is carbon-free.

    A Boeing 737-900 with 180 passengers on board gets about 99 passenger-miles to the gallon for a 1000-mile flight. That is better than most cars with 3 passenger.

  9. Re:How efficient is hydrogen really? on Germany Unveils a Hydrogen-Powered Passenger Train (fortune.com) · · Score: 1

    Another thing, H2O is a lousy combustion product if you are building an ICE. The problem is that H2O has a very high heat of vaporization, 44kJ/mol, and it is nearly impossible to recover this heat. When you burn hydrogen in an ICE, you are spending a lot of energy essentially boiling water. You get 286kJ from burning a mole of H2 gas, but you lose 15% of that heat because you cannot condense the water vapor.

Batteries will be needed for EVs and the batteries in the EVs will massive controllable storage facility. When the batteries are no longer suitable for EVs, they can be re-purposed for grid storage for a few more years, and finally they can be recycled.

Obviously, you pull to the right to pass on-coming car, but what is there is little to no on coming traffic? The 'unexpected' tends to come for the sides of the roads and driving near the center of the road increases visibility and gives you more time to react.

    You are comparing the estimated cost of the hyperloop to the actual cost of an airline terminal.

    Less land?? Are you forgetting the amount of land that the tube take up?

  22. Cool but silly idea on How Amazon's Drone Deliveries Will Work (yahoo.com) · · Score: 3, Interesting

    The idea sounds cool enough, but how does it benefit the customer? I am struggling to figure out what issue is solved by drone delivery. Drones are not faster than cars so it is not a speed issue. The drones require pilots so it is not a labor issue. Drones are expensive compared to a scooter or a used car so it is not a cost issue. Drones can't fly in bad weather so it is not a reliability issue...

    If you are only 10 miles from your customer, you might as well open a retail store. Order on-line and pick up at the counter.

      Pizza delivery has been 30 minutes or less for decades and they do not need drones.

    . 12 years is about the longest half life of the 'dangerous stuff', which means you stop caring in a hundred years or so AT MOST

    Bullcrap. cesium-137, strontium-90 and iodine-131 have half lives much longer than 12 years and are and are some of the more dangerous nuclear byproducts out there. You are a damned fool if you think you can stop caring about these after "100 years of so."

    You are right in that materials with very long half lives are not that dangerous due to the fact that they are not that radioactive. Stuff with very short half lives does not stick around for a long time so it is not a long-term hazard. But you are WAY off in your assertion that a spent fuel rod is perfectly safe after a 100 years of so.

    Unfortunately, it really is not. Pumped hydro energy storage facilities do work; they are reasonably efficient and they can store a lot of energy. But you have to have a pretty unique combination of geology and hydrology to build such a facility.
