Can Nuclear Fission and Fusion Power a Bicycle?

Click For Summary
SUMMARY

The discussion centers on the feasibility of creating a bicycle powered by nuclear fission or fusion, specifically utilizing radioisotope thermoelectric generators (RTGs) as a power source. The best candidate for an RTG is 238Pu, which produces 0.54 watts per gram, necessitating approximately 400 grams of plutonium for pedal assist and nearly 75 kg for full electric motorcycle capabilities. The estimated cost of plutonium is $4,000 per gram, leading to a total expense of around $300 million for the plutonium alone, making this concept impractical for consumer use.

PREREQUISITES
  • Understanding of nuclear fission and fusion processes
  • Knowledge of radioisotope thermoelectric generators (RTGs)
  • Familiarity with electric bicycle power requirements
  • Basic principles of weight and cost analysis in engineering
NEXT STEPS
  • Research the design and functionality of radioisotope thermoelectric generators (RTGs)
  • Explore the implications of using 238Pu in practical applications
  • Investigate electric motorcycle power requirements and alternatives
  • Examine the economic feasibility of nuclear materials in consumer products
USEFUL FOR

Engineers, physicists, and hobbyists interested in advanced bicycle technology, nuclear energy applications, and electric vehicle design.

is it possible to create a bike involving nuclear fission and fusion . by using any nuclear reactant.
 
Physics news on Phys.org
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 http://www.zeromotorcycles.com/zero-s/specs.php 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.
