  1. Not even close to economically feasible on Pacific Trash Vortex To Become Habitable Island? · · Score: 2, Insightful

    This is a terrible idea even though it gets suggested all the time. The cost of gathering plastic from the trash vortex in the ocean - a very expensive environment to operate in - is literally orders of magnitude higher than gathering plastic by buying and digging up a landfill. I haven't heard about anyone flipping landfills for a 10,000% return, which is what it would take to indicate that it's worth getting plastic out of the Vortex. You are going to spend at least $100, maybe as much as $1000, to get every $1 of plastic out. There are much funner ways to waste money - drugs and hookers, for example.

  2. Re:Don't worry... on Trigonometry Redefined without Sines And Cosines · · Score: 1

    For a physicist or computer scientist, the principles of trigonometry are invaluable.

    Dude, wtf are you talking about?

    I have a masters in CS, and I work at a well-known brain-heavy company, and I never use trig or calculus. Algorithm and data structures matter constantly, databases, compilers, computer architecture, graphics, number theory, graph theory and combinatorics all matter occasionally. But I haven't had to take a sin or do an integral yet.

  3. Re:Many pros have a history in computers on Geeks Playing Poker? · · Score: 1

    Paul Phillips, who was the CTO of Go2net.com, is another very successful WPT player. And Robert Varkonyi, who won the WSOP a few years back, is a computer guy. There are a lot of us in the poker world.

  4. The problem with electro-accretion on A Solution for Coral Reefs in Peril · · Score: 3, Informative
    Various people above mentioned other uses for electro-accretion, like building floating cities ala Marshall Savage. Unfortunately his energy numbers are off by a factor of 42 - he didn't integrate power over time, just used power as his energy number. It turns out to be just too inefficient to be useful for much except coral restoration. The main problem is that the accreting seament doesn't conduct, so it dissipates more and more energy as it builds up. So its way more expensive that just shipping cement from land (unless you are doing something tricky like restoring reefs).

    Details and references here. (I replied with some comments about this, but I didn't have an account so they have 0-ratings, so I got an account to post this. Hope its not too bad form to comment in multiple places.)
