  1. Do they plan to retrofit ITER with turbines if it is successful or build a new reactor?
  2. So about ITER, the awesome fusion reactor being built in france. Their website says that during peak operation, more than 1 GW of heat must be dissipated using cooling water. If all that heat is being produced, why do they have no plans to recover any of it with turbines?
  3. China has always been very effective when they want to do something, and they are fast learners. However they seldom entirely design their own technology. They copy others and put their own name on it. There should be a certain amount of shame in this to temper their industriousness.
  4. You are onto something here, but it not ASAS that needs to be in the center. It's the controlling part. Any probe core or docking port will do, just click "control from here" on it's context menu before launch. However, Since C7 has completely fixed ASAS for the next version, this knowledge will not be applicable for long.
  5. Use kxp.olex.biz to determine when you should launch.
  6. Man I just spent like 30 minutes reading about ITER What a cool project!
  7. Would it be possible to achieve positive net energy fusion with a sufficiently large budget today, or is the technology blocked by limitations in scientific understanding?
  8. I was reading this paper by Yoshua Bengio, and a certain passage stood out to me. I've always though that verbal communication was a painfully narrow and lossy medium, and that one day, we would have the technology to bypass it by allowing people to share more direct representations of their thoughts via neural-computer interfaces. However, this quote casts doubt on not only that possibility, but the possibility of even plain verbal communication. Somehow, since birth, every person has inferred the meanings of tens of thousands of symbols and can use them fluently to communicate. If we were given a new interface, with an an excessively high bandwidth, for example, the power to instantly communicate a mental image, some form of language would be necessary to represent it between brains because we would all have a different distribution of synaptic strengths and activation levels that could represent it. The burden would be on either the people communicating, to learn the shared language, or the computer system to learn each individual's unique neural structure and translate between them. I suspect that there will be a tradeoff between the speed of communication and the time needed to learn the language used.
  9. All ICBM's are launched on sub-orbital trajectories. Both the USA and the USSR tested ICBM's with nuclear warheads, and tested detonations over the poles.
  10. I hope that when they add consumables for the manned missions, that the food resource is just called "snacks"
  11. You left out So they've replicated part of what corn can already do for us, but with the freedom to supply electricity from any source. Neato! Hydrocarbons are a dense way to store energy and quite valuable given today's infrastructure. However, I think it's still crucial that we migrate away from cars and their hydrocarbon burning engines, even if we can make the fuel entirely from renewable sources. They just pose too many other problems for modern cities and they are a needlessly wasteful way to get around.
  12. NASA found that in the event that we would need to deflect an asteroid form Earth, that a standoff nuclear detonation was practically the only affordable and effective solution and that an agreement between space faring nations would be necessary to proceed with it. I assume that if any of these nations also had a good strong desire to use nuclear energy in space for the purpose of high efficiency engines, that a similar agreement would be made. I don't think there will ever be any space warfare.
  13. We have enough uranium to last about 100 years, and enough fossil fuels to last about 100 years too. I think that should be sufficient time to master fusion.
  14. Antimatter is a way of potentially storing energy, not a source. It's not like we can mine antimatter from the planet. It has to be created in a particle accelerator consuming massive amounts of energy. It's a very troublesome way of storing it anyways.
  15. "The future" is a little ambiguous so I've broken it down into powers of 10. 1 year from now: Fossil fuels 80%, Organic renewables 12%, Non-organic renewables 5%, Nuclear 3% 10 years from now: Fossil fuels 79%, Organic renewables 12%, Non-organic renewables 6%, Nuclear 3% 100 years from now: Fossil fuels 66%, Organic renewables 16%, Non-organic renewables 10%, Nuclear 8% 1000 years from now: Fossil fuels 15%, Organic renewables 35%, Non-organic renewables 25%, Nuclear 25% 10000 years from now: Fossil fuels 1%, Organic renewables 45%, Non-organic renewables 49%, Nuclear 5% 100000 years from now: Fossil fuels 0%, Organic renewables 10%, Non-organic renewables 90%, Nuclear 1% Fossil fuels includes: Oil, coal, and natural gas. Organic renewables includes: Corn ethanol, burning biomass such as wood, and any genetically engineered organisms that produce fuel or electricity from light. Non-organic renewables includes: Solar, geothermal, hydroelectric, tidal, wind, and any exotic astronomical forces our descendants may discover. Nuclear includes: fission of Uranium-238, Plutonium 239, Thorium 232, and the Fusion of Hydrogen-2 or 3 into Helium.
  16. Wow, seems like a headache. Sorry I can't help you. Thanks for leaving some links for future searchers.
  17. There is usually no need to transfer electricity, because panels will charge all batteries on a vessel that have room. by they time you even manage to click both batteries, they'll probably already be full.
  18. So I'd like to know more about weightless parts. Apparently some parts have zero mass in flight, despite having a reported mass value in the VAB. (mechjeb will agree, in the VAB, but not in flight) Is there a list of all the parts which have have no mass in flight?. Right now I know the strut and the landing gear. Are these bugs or intentional?
