Nuclear fission and fusion

  1. Jun 21, 2015 #1
    is it possible to create a bike involving nuclear fission and fusion . by using any nuclear reactant.

    Maybe a very big highly radioactive bike,

    You could in principle make use of something like the RTG power sources used by some spacecraft.
    This would provide electrical energy sufficient to power a small electric motor.

    I'm not sure what you're asking. Could you elaborate a little?

    Assuming you're not trolling, it happens all the time. It takes electrical power to build bikes. Fission powerplants supply some of that power. QED

    According to the RTG wiki page 238Pu is the best candidate for an RTG putting out 0.54 watts per gram and needing 2.5mm lead to absorb all radiation. According to the electric bicycle wiki page power requirements are 200-750 watts. So you'd need at least 400 grams of plutonium to power it and that's only for pedal assist, if you want a full on electric motorcycle according to this company the power requirement is ~40kw, in other words you'll need nearly 75kg of plutonium...

    The bike is definitely going to be a heavy bit of a beast if that's the case.
    Might be a bit less heavy than a top of the range Harley-Davidson though.

    Not to mention expensive! It's reported at $4,000 per gram. That's $300 million dollars total. If the bike itself was a copy of the most expensive bike sold (that I can find with a quick google) it would add nothing more than a blip to the total bill.
