  1. Re:Energy on Dry-Ice Heat Engines For Martian Colonists · · Score: 1

    A miror is easier to produce than a solar pannel.

    Build a bunch of mirrors and concentrate the sunlight on a solar panel.

  2. Re:Energy on Dry-Ice Heat Engines For Martian Colonists · · Score: 1

    The question is if the costs of harvesting and transporting the dry ice are sufficiently low to enable this as a viable solution.

    The killer will be the huge investments to set up the transporting infrastructure. You need energy first.

  3. Re:Energy on Dry-Ice Heat Engines For Martian Colonists · · Score: 1

    Most of our technologies aren't that efficient - anything running on electricity is typically 70% waste heat.

    Good electric motors produce less than 10% waste heat, and that little bit of waste heat is probably beneficial in a cold environment to keep things running smoothly.

  4. Re:Energy on Dry-Ice Heat Engines For Martian Colonists · · Score: 1

    I think the idea is that you can take a small amount of heat energy and turn it into a larger amount of electrical or mechanical energy

    There's still a law of conservation of energy, even on cold Mars.

    I think it would be easier to set up a bunch of solar panels at the middle latitudes. Or go nuclear.

  6. Energy on Dry-Ice Heat Engines For Martian Colonists · · Score: 1, Interesting

    You still need energy to heat up the CO2. And if the energy is available in electric form, which is most likely, why not simply drive an electric motor instead ?

  7. Re:Connector life? on Does USB Type C Herald the End of Apple's Proprietary Connectors? · · Score: 3, Funny

    In the past year, two tablets in my household have died because the micro-USB ports which serve as their power connectors had ceased to work - presumably due to wear.

    Yeah, I had to fix my tablet's micro-USB port twice. One of the pins had to be resoldered to the board. These micro USB connectors are way too delicate for daily use.

    That's what people said just before the .com crash

    Most USB connectors have auto-reverse. It only works properly if you don't manually reverse at the same time.

  10. Re:We've redefined success! on Mental Health Experts Seek To Block the Paths To Suicide · · Score: 2

    So we should allow people to get professional assistance on how to take their own life in a peaceful way. That way there's a graceful way out for those who have really considered the issue well. At the same time, reduce access to easy suicide on a whim.

  11. Re:Maybe in a different country on Mental Health Experts Seek To Block the Paths To Suicide · · Score: 1

    If you lock every single door in your house, including your bedroom door, the risk of dying in a house fire because you can't get out quickly enough probably outweighs the benefit of the extra protection.

  12. Re:Global Warming on California's Hot, Dry Winters Tied To Climate Change · · Score: 1

    It's climate change caused by global warming. Both expressions highlight different aspects of the issue, but both are equally valid.

    Also, both terms were already in use long before it became a well known public issue.

    No significant average temperature change in 15 years

    Look at the trend, and don't stare too much at the 2-sigma outlier in 1998.

    The trend is still as robust as it was. And before you complain that I'm linking to a wordpress blog, you can download the data here, and draw your own graph: http://data.giss.nasa.gov/gist...

  15. The amount of skin pigmentation (among many other things) is determined by genetics.

    how many white races are there

    That depends on how closely you look. The differences are small.

    You're confusing race with genetics. The two are not related in any way. Race is a human construct.

    You know what'll stop backward hicks like ISIS? Technical and social advance

    Keep dreaming. People who are eager to destroy 6000 year old artefacts aren't interested in your technical and social advance.

    Would have been nice if TFS had included an explanation of what the TSYNC feature is.

  19. Re:Laws of thermodynamics don't apply at GoodYear on New Concept Tire Could Recharge Car Battery · · Score: 2

    The flexing of the tires is helping to make the ride more comfortable. If you harvest energy from that, they'll get stiffer, and you'll feel more bumps and vibrations. People don't want that. Otherwise, they could have stiffer and more energy efficient tires already.

    I'll be happy to distribute some of my resources, but only in return for something of equal value.

    I don't have to explain anything

    My point exactly. You haven't explained anything, and you've stopped trying.

    The atheist's position that "it must be, because we reject any alternative explanation" is not science

    I reject any explanation that requires unexplainable and untestable magic. I'm not aware of any reasonable alternative explanations that don't require magic.

    Evolutionists want to claim their theory is "settled science". It's not. It's not even a testable theory

    It's perfectly testable in lots of different ways. Maybe you're thinking of abiogenesis ?

    Same thing. You haven't explained the creator itself. You haven't explained the creation process. You can't predict anything.

    I agree it's simple, but it's also meaningless. You have no answers. The only thing you've accomplished is that you've stopped asking questions.
