The World's Nine Largest Science Projects 89

Posted by samzenpus from the my-science-is-bigger-than-yours dept.
JBG667 writes "Nice overview of the 9 largest science projects currently ongoing. Some of the usual suspects are on the list including CERN, Space Elevator, Space Station, etc. As well as some lesser known including a 3,000-foot-tall 'Solar tower,' the ANTARES underwater neutrino detecting array, and more. Nice read for science buffs."

          Fusion has this strange dichotomy in it, low start temperature = more pressure needed, high start temperature = less pressure. So they aim to kickstart a reaction from multi-million degree plasma because it doesn't require an entire sun worth of gravity-induced pressure to shove the atoms together. Only about a third of a sun, which might be obtainable with earth-sized tools.

              That's precisely what I meant. An explosion could give the massive piston a lot of PE when it moves it up. If you surround the explosion with water, it could create a lot of steam pressure.

        • We don't have any materials that we can use to contain a fusion bomb, and also an internal combustion engine would be a very very inefficient way to use that energy, most of which would be heat or radiation as opposed to expanding gasses.

      • Obviously it can't be an experiment if the version number = 2.0.
    • Even if you consider the initial development of the internet as a science project, the project itself was fairly small. Do you consider research into vehicles and transportation to be a big science project just because there are millions of them on the road now?

    • The internet was more of an applied engineering project than a "science experiment."

      It was essentially an application of already existing technologies, just in the same way that I wouldn't necessarily call the development of Linux or hardware (eg. the iPod) "science".

    • It stopped being a "science" experiment when it became commercial, back in 1990 or so. Or else you could say, it became a hobbyist project instead of something driven by scientists...

      NASA has already run competitions to build elevator climbers. There are millions (perhaps billions) being invested in the development of carbon nanotubes as a viable building material. If such time, energy and money were being spent on building a warp drive, then you might have a point.

        • What makes you think they are not? Most researchers into nanotubes (and there are some in my department) when asked what the applications of their work are will mention space elevators first. There are few other applications that require such ridiculously strong materials - steel suffices for pretty much everything people want to build right now.

          • If we can devise a method to manufacture them cheaply, they'll become very widely used.
