Inertial Confinement Fusion (ICF)
® the final products of a fusion reaction weigh 0.7% less than the initial ingredients, thus 0.7% mc2 is converted into energy: One gram of fuel yields 175,000 kW-hours of energy
Deuterium-Tritium fusion reactions have the biggest cross section
Energy is released primarily in the form of fast neutrons; there are various schemes for harnessing this energy
A working test-reactor is decades off still, but fusion power is an attractive long-term solution to our energy needs
