This corresponds to a total scientific energy gain of 0.7 and a capsule energy gain of 6. [14] While the experiment fell short of ignition as defined by the National Academy of Sciences – a total energy gain greater than one – most people working in the field viewed the experiment as the demonstration of ignition as defined by the Lawson ...
As originally formulated, the Lawson criterion gives a minimum required value for the product of the plasma (electron) density n e and the "energy confinement time" that leads to net energy output. Later analysis suggested that a more useful figure of merit is the triple product of density, confinement time, and plasma temperature T .
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 condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven , or ...
NIF achieved net energy gain [261] in 2013, as defined in the very limited sense as the hot spot at the core of the collapsed target, rather than the whole target. [262] In 2014, Phoenix Nuclear Labs sold a high-yield neutron generator that could sustain 5×10 11 deuterium fusion reactions per second over a 24-hour period. [263]

Formulas have been devised to estimate energy expenditure in humans, but they may not be accurate for people with certain illnesses [13] [14] [15] or the elderly. [16] Not all formula are accurate in overweight or obese individuals. [17] Wearable devices can help estimate energy expenditure from physical activity but their accuracy varies. [18]
I tried Factor’s pre-made meal delivery service for a week to help make meal planning at home easier and stress-free. Here’s what I thought about the service’s ready-to-eat meals.
The Joint European Torus (JET) was a magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy in Oxfordshire, UK. Based on a tokamak design, the fusion research facility was a joint European project with the main purpose of opening the way to future nuclear fusion grid energy. At the time of its design JET was ...
