    The solar energy concentration is not sufficient to convert the amount of energy we need with the technology we have without bulldozing half of the available landmass.

    According to SciAm's "A Solar Grand Plan" all of the electricity used in the US in 2006 would take less land than in the Southwest to produce. But you're smarter than they are right?

    If it were as easy as you think, it would already be solved, for Pete's sake.

    If the door, opening, is on the top then where is the compressor, you know the thing that heats up? Heat rises so if it's on the bottom then the compressor has to work harder thus creating more heat. There are some manufacturers that place the compressors on top, such as Sun Frost.

    Are you talking about pumped storage or simply using a traditional power plant to cover the difference.

    I didn't mention any particular method of storing energy but there are a number being worked on. Besides fuel cells, where excess energy is used to produce hydrogen, there's thermal energy storage, ultra capacitors which someone above mentioned may become feasible, and other methods of energy storage. I think one of the more promising sources for baseload power is geothermal. The Department of Energy [pdf] says "Because geothermal can provide a large amount of sustainable, indigenous, clean, base load and affordable energy for the nation"

  19. Re:Wind? on Why Sustainable Power Is Unsustainable · · Score: 2, Interesting

    Plants use solar, but very few natural things use wind or tidal power. Nature has had a very long time to try and fill these energy niches, so it is a safe guess that they can't produce enough energy to sustain a large population at a reasonable standard of living.

    It may not be true in some parts of the world but the US has plenty of potential wind energy. The Wind Energy Resource Atlas of the United States lists the potential of various places. For instance just as the Picken's Plan covers, the Rocky Mountains alone have enough potential to supple the 48 continuous states with electricity. There are plenty of other places as well.

    Okay.

    In a netbook situation, where I may not have gigabytes up on gigabytes of storage for dual booting, I will have to go with Windows.

    Yea, when I got my MBP the largest 7200 rmp hdd, which is needed for graphics and photography, for it was 160GB. As I only had about 25GB of free space on it a few weeks ago I replaced the hdd with a 320GB hdd. Now I'm thinking about setting up the laptop to dualboot by installing Ubuntu. If so what I'll do is make 3 partitions on the hdd, one for Leopard, one for Ubuntu, and one for user files. I'm not sure but I think I'll give each OS partition 30 to 50 GB.

    Then don't get one. I'm typing this on a 17" MacBook Pro. Before I bought it I looked at other laptops and I saw one in Best Buy with a 21" lcd. I started drooling, then I saw the OS, Windows. I wish Apple released as big a laptop as that one. Forget a 17" laptop, some people have said 15" was too big. But not for me. Does it take up too much space? It fits in my small backpack, and with it in the backpack that one fits in my larger one, with space for large books. Does it weigh too much? I used to hike and march with a backpack weighing 60+ pounds when I was in the Army. After I got out and started college I rode my bike to campus, about 8 miles, daily with the backpack weighing at least 20 pounds. If I can't carry 10 pounds, and the MBP weighs less than 7, I'm in real bad shape.

Actually I replaced the drive because there wasn't much space left and one of the geniuses in an Apple store warned me about that.

  25. speed on Ubuntu Wipes Windows 7 In Benchmarks · · Score: 1

    True, there was one interesting metric where Windows got its ass kicked (copying small files around). But for the most part, I saw no major ownage. In fact, it showed that Windows did a better job with large files and had a faster turn-around time to boot & shut-down.

    While Windows 7 did bootup and move large files from one place to another on the same drive faster it was slower when shut down. The Shutdown Time chart shows the slowest version of Ubuntu taking 10 seconds to shutdown whereas Windows 7 took 13.4 seconds. Then for copying large files from USB flash drive to hard disk Windows 7 took 19.6 seconds whereas the slowest Ubuntu took 19.4 seconds.

    In general it looks pretty much like it's a wash, though Windows 7 was faster than previous versions of Windows.

    Other than that, they stacked up pretty evenly (at least the x86 versions of Ubuntu 9.04 & Windows 7 - That's all I was really looking at).

    They didn't test the version of Ubuntu I was interested in, the 64 bit server edition. I'm hoping to install it in the next few days.

    How exactly did "Ubuntu Wipe Windows 7"?
