Power Generating Spacesuits

Maggie McKee writes "Piezoelectric sensors could help power future space missions. Astronauts' spacesuits may one day be covered in motion-sensitive proteins that could generate power from the astronauts' movement, according to futuristic research being conducted by a new lab in Cambridge, Massachusetts, US. Such 'power skins' could also be used to coat future human bases on Mars, where they could produce energy from the Martian wind. Eventually, the biologically derived suits might even be able to heal themselves."

      Of course it would add resistance. Since we don't want their muscles atrophy, I would imagine the resistance is seen as a feature rather than a bug.

      Except that you don't really want them getting extra exercise while they're in their suits -- one of the big problems with space construction is that working in space suits is very tiring. The rest of the time it's not enough to exercise to prevent muscle atrophy... you also have to load your bones to prevent bone loss.

    What? The suits are powered by the astronauts' movement, and that energy is provided by food? It's more conserving energy than anything. If we could somehow train our astronauts not to play golf on missions, we could save billions on R&D.

  8. Why piezo-electric? by 140Mandak262Jamuna · · Score: 5, Interesting
    Given that no machine has 100% efficiency, these generators cant produce more energy than what the astronauts muscles could deliver. So dont confuse these with generating power like in solar cells or nuclear reactors. But there is always need for electrical energy so they might come in handy. But why these piezo-electrics?

      The problem is, they can't. You can't get something for nothing. If the suit generates electricity when the astronaut moves, then it will offer resistance to the astronaut's movement; that's basic conservation of energy. The question is, how *much* will it hamper the astronaut? If it's too small to be noticeable, than that's a good deal, but that seems a little too good to be true.

  12. The energy doesn't come from nowhere by EmbeddedJanitor · · Score: 3, Interesting
    This means that the astronaut will have to work harder (consuming more fuel/oxygen, generating more waste heat that needs to be processed). A human working flat out is only good for a few hundred watts. In space that would be hard to achieve. Anyone who has tried doing hard physical work in weightlessness will tell you how difficult that is. I have not worked in space, but I have worked underwater which was pretty difficult.

    Sure this would give them a much needed work-out, but that is far better to do inside where there is better oxygen supply, waste heat/water processing etc.. Rather use an exercise bike driving a generator which is likely to be far more efficient.

    Basically this sounds far more like a solution looking for a problem that anything really useful.

    The apocryphal story of NASA spending millions of dollars to invent a pressurized ball point pen that would work in zero gravity and USSR deciding to use a pencil comes to my mind.

    The one that's a blatantly not true? I'm against space exploration for many reasons, but even I know this story is utter bullshit.

    1)Fisher developed the space pen without a dime from NASA, and sold them to NASA at a reasonable price.

    2)Both the US and USSR used pencils.

    3)Both stopped using them because the dust/filings/broken tips floating around were bad for people and equipment.

    Incidentally, I have a Fisher pen; it's the smallest one they make (I think), a two-piece unit where the cap flips around to make it a full-length pen. It's a great pocket pen; the ink seems to be quick-drying (left-handed people will appreciate this and know what I mean), not too pricey ($10 I think? Maybe $15?) small, always works, and with the cap off, it's a full-size writing implement and very sturdy when "assembled." Not like one of those cheesy telescoping jobbies that bend and are too thin to hold. An o-ring-like seal keeps the cap on firmly when stored and keeps the laundry detergent out (yes, proven more than once.)

    It's quick to whip out (cough) and always works, unlike half the pens at cashiers which a)can't be found and b)barely work. It also garners the occasional impressed comment. My only beef is that the clip came off after a month or so in my pocket- would have been nice if they had spot-welded it on instead of just press-fitting it.

  14. Energy efficiency, not generation. by aibrahim · · Score: 5, Interesting

    There is a lot of complaining that this will make the suits harder to bend and a number of other non-sense.

    The point is that a lot of energy is already wasted by normal movement. It goes into things like crushing your shirt sleeves, friction, sound etc.

    You have to make the space suits out of something... it may as well be something that can recapture energy normally wasted in motion.

    Some have brought up the notion that these types of devices use more energy to make than they can capture. If it costs more energy to make the suits than they can generate... well that is irrelevant. The energy would be expended on Earth, so the mission gains some energy efficiency for "free." This becomes a consideration only if the suit has to be manufactured during the mission... perhaps as a replacement.

    Don't get me wrong... this is far from the primary way to get energy. Take the example from the article of using this to generate energy from the Martian wind. Instead we might use this "wind mill" technology. However, if you have wind buffeting a static structure, it makes some sense to capture some of that energy if (and that's a huge IF) you can do so just by changing the materials used on the exterior. It may make more sense to coat the windmills with this stuff, and build the shelters underground.

    Another clue that the article should not be taken seriously is the following quote: "Peter Dallos of Northwestern University in Illinois, US, which patented the prestin molecule in 2003, says prestin may be 10,000 times more efficient at generating power than the best manmade material." That makes no sense. Efficiencies for converting mechanical power to electricity can be quite high (e.g., greater than 80%). Even if one were talking about efficiencies on the order of only 20% (such as we see with photovoltaic cells), 10,000 times that would be 2000%. Even proponents of perpetual motion machines would probably regard as ludicrous the claim that you could get 20 times as much electrical energy out as mechanical energy put in. My guess is that the folks at IntAct Labs are trying to create a buzz with this nonsense because a stock offering for the outfit is in the offing. I would not touch it.
