Fusion Power
Over on the Aircraft thread the topic of He3 fusion was brought up. I hadn't really considered that so I looked on Wikipedia and this is some of what I found
The second possibility, fusing 32He with itself (32He + 32He), requires even higher temperatures (since now both reactants have a +2 charge), and thus is even more difficult than the D-3He reaction. However, it does offer a possible reaction that produces no neutrons; the protons it produces possess charges and can be contained using electric and magnetic fields, which in turn results in direct electricity generation. 32He + 32He fusion has been demonstrated in the laboratory and is thus theoretically feasible and would have immense advantages, but commercial viability is many years in the future.[13] The amounts of helium-3 needed as a replacement for conventional fuels are substantial by comparison to amounts currently available. The total amount of energy produced in the 21H + 32He reaction is 18.4 MeV, which corresponds to some 493 megawatt-hours (4.93×108 W·h) per three grams (one mole) of ³He. If the total amount of energy could be converted to electrical power with 100% efficiency (a physical impossibility), it would correspond to about 30 minutes of output of a gigawatt electrical plant per mole of 3He. Thus, a year's production would require 52.5 kilograms of helium-3.[citation needed] The amount of fuel needed for large-scale applications can also be put in terms of total consumption: electricity consumption by 107 million U.S. households in 2001[14] totaled 1,140 billion kW·h (1.14×1015 W·h). Again assuming 100% conversion efficiency, 6.7 tonnes per year of helium-3 would be required for that segment of the energy demand of the United States, 15 to 20 tonnes per year given a more realistic end-to-end conversion efficiency.[citation needed] So here is my idea. The Project generators operate using Bubble Fusion https://en.wikipedia.org/wiki/Bubble_fusion Now bubble fusion, like cold fusion is a darned touchy subject but I can see it working in a fictional universe. This will give a reactor that doesn't need an unstable radio-isotope for fuel, won't produce vast numbers of deadly fast neutrons or a lot of heat which will require massive shielding. Since this design came from the future I expect a bit of hand wavium here. Inside the fusion pack is a He3 tank, the reaction chamber, a lot of graphene sheeting and other nanomaterials that capture, convert and transport the energy so that all that comes out is clean electricity at a nice standard voltage. Just a few thoughts |
