Energy from nuclear fusion
Fuse light nuclei and calculate the energy released from the mass defect.
What to notice
A tiny loss of mass — under 0.4 % — releases millions of electronvolts per reaction.
Key relation
Q = (Σm_reactants − Σm_products) c²
Try this
Compare D–T with D–D fusion per kilogram of fuel.
What you can change
- Reaction: choose D + T → ⁴He + n, D + D → ³He + n, D + ³He → ⁴He + p
- Fuel mass: 0.1 to 100 g
