However, while this was scientifically a success, [13] the experiment in practice produced less than 1% of the energy the facility used to create it: [14] while 3.15 MJ of energy was yielded from 2.05 MJ input, [15] the lasers delivering the 2.05 MJ of energy took about 300 MJ to produce in the facility.
Energy per reaction is the energy released in each fusion reaction; This equation is typically averaged over a population of ions which has a normal distribution. The result is the amount of energy being created by the plasma at any instant in time. Lawson then estimated [5] the radiation losses using the following equation:
Total photosynthetic efficiency would include more than just the biodiesel oil, so this number is a lower bound. Contrast this with a typical photovoltaic installation, [ 11 ] which would produce an average of roughly 22 W/m 2 (roughly 10% of the average insolation), throughout the year.
Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines- Internal combustion (gasoline, diesel and gas turbine-Brayton cycle engines) and
Finally, there's good news for homebuyers and for homeowners who want to refinance their mortgages: The 30-year fixed mortgage rate now averages 6.73%, dropping significantly from its 20-year peak ...
The reaction of hydrogen fuel at the facility produced about 3.15 MJ of energy while consuming 2.05 MJ of input. However, while the fusion reactions may have produced more than 3 megajoules of energy—more than was delivered to the target—NIF's 192 lasers consumed 322 MJ of grid energy in the conversion process.

The explosion of the Ivy Mike hydrogen bomb. The hydrogen bomb was the first device able to achieve fusion energy gain factor significantly larger than 1.. A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state.
The US National Ignition Facility, which uses laser-driven inertial confinement fusion, was designed with a goal of achieving a fusion energy gain factor (Q) of larger than one; the first large-scale laser target experiments were performed in June 2009 and ignition experiments began in early 2011.
