Fusion power

Advantages

• Exceptionally high-density energy 
• Process intrinsically safe: no uncontrolled fission reactions, no risk of fuel meltdown or large radioactive releases
• No production of high-level radioactive wastes; Neutrons involved in the D-D and D-T reactions will create low-level radioactive waste
• Virtually limitless energy supply:
  
  - Hydrogen, deuterium and boron are abundant on earth
  
  - Tritium can be produced (using lithium)
  
  - Helium-3 can be found on the moon(or produced)

Challenges

• Achieve the triple product for the reaction:
  
  T°C: very high temperature (~100k°K) to heat plasma
  p :  sufficient plasma particle density                t: sufficient confinement time (minutes for magnetic confinement, microseconds for inertial confinement)

• In parallel maintain low-temperature (<30°K) superconductors for magnetic confinement
  - New types of superconductors, including high-temperature (70-100°K) superconductors are being developped

• Find resistant material able to sustain high temperature + radiations + neutron embrittlement
• Reach energy gain* by managing the triple product: never been reached experimentally so far.

* Energy output should be higher than energy input
