  1. I've read that CO2 emissions from volcanoes are in the 300 million tons a year range tops. Is this is true and if it is does it count subsurface ocean volcanoes? If not how much are they estimated to emit per year?
  2. As much as I'd like to see a transporter I do not see it happening in our lifetime and it may well be impossible. I can't say for sure it is because things once thought impossible are reality today and as our understanding of the way the universe works improves new things become possible. But not everything imagined in science fiction is possible. I think AI is inevitable and that machines will eventually be able to do all physical tasks a human can do and do them better and someday be cheap enough so that the average middle class home can afford one or more. Household chores will be someth
  3. I'm not saying it is 90% off. I'm just saying if these things were only able to take care of 1/3 of our energy it would still be a great accomplishment. That would be more than nuclear power plants' contribution to our power. Also the 3 times number given is from 18.5% efficiency as opposed to the 44%+ they've reached in labs but "aren't cost feasible yet". I would like to see some competition arise with this technology, multiple labs trying to come up with their own version of solar roadways, that often spurs innovation.
  4. Would such an island be stable? Many plastics degrade over time in contact with UV. Is there a solution to this?
  5. According to one of the links I followed, it could potentially produce 3 times the amount of electricity we currently use (or used in 2009). Even if these numbers are off by 90% that's 1/3 of the power we use, still pretty impressive. I suppose cost is a concern which may potentially be a problem when we know more.
  6. Most areas of science have some interest, geology, chemistry (is there a chemistry forum?), life science, physics and astronomy. My main interest is life science (evolution, taxonomy and anatomy: plant and animal), followed by astronomy and cosmology at a close second.
  7. An interesting idea to say the least. I don't know nearly as much about solar energy as I want to, but we have certainly have enough roads to put a dent in our energy needs if it works. I don't have criticisms as much as questions. How much energy would they produce per mile of road? How much would it cost per mile? The panels may have a long life but do they lose effectiveness over time? Might a panel still work in 10 years but only produce 20% of the energy of new panels. How many miles of them would be needed to cover 25% of our energy needs? Don't get me wrong, I'm not trying to rai
  8. So your guess is the bulge contains about 33% of the stars. So would the halo have about 1-2% of the stars? That being the case (and realizing it was an educated guess) is this a reasonable distribution?: Bulge- 33% Disk- 65-66% Halo- 1-2%
  9. I've heard wildly different numbers for how many stars there are in our galaxy. On the low end I head about 100 billion, this was several years ago. Today I read numbers like 200 billion to 400 billion. Whatever the numbers are this doesn't tell the whole story. I know stars in the bulge are packed a lot tighter, than in the spiral arms and the halo. But are the percentages known? What percent of the galaxy's stars are in the bulge? the spiral arms? the halo? Are the majority of the galaxy's stars in the bulge? Does anyone know how many stars are in the arms?
  10. Kelzan here. I'm from California and I've always been interested in science, specifically space and life science. I am always asking questions, some I can't easily find the answers to and I thought this would be a good place for learning as well as passing on what I know when I can.
