We had a working reactor in 1969 at the Rutherford. I don't know why it was never developed. Dr Chris.

I'm lowkey crushing on Jasmine. I love her voice and the way she reads the news sounds so professional.

Kind of reminds me of Troi on Star Trek TNG.

1. Zap's Z-pinch method will never work because of the problem of plasma scattering problem. for fusion to happen the ions need to hit dead on. The plasma density and non polar\chaotic direction of ions will prevent it from producing over unity energy. The Univ. of Wisc. experimented with this method over 20 years ago, with dismal results. 2. Common Wealth's compact reactor using High temperature Superconductors is doomed from the start because high neutron flux produced by fusion cause squelching of the superconductor material (ie suddenly losing superconducting). This is way ITER abandoned the use of HT Superconductors during the design phase 20 years ago.

Certainly superconducting magnets will be sensitive to neutrons, but they will be, and must be, protected by the metre thick layer of lithium that is needed to breed tritium. Whether that can be done efficiently is another question.

@@johnh6245 The point was to make a compact reactor. The SC magnets would have to be on the inside considering lithium is a metal & conducts electricity. its not going work any way it would operate at too high of plasma density. ITER is big because its goal is low pressure plasma to avoid plasma scattering problems. Ions need to hit each other dead on. a glancing impact is a dud (no fusion. When you have too many plasma ions colliding into each other the scatter decreasing the ability to collide dead-on and fuse. Fusion power is doomed as the costs for a power plant with breeding blanket, & power extraction would cost more than 10 times of a fission system.ITER will cost more than $32B for a 500MWth with no breeding & no power extraction. I don't know anyone that is going to want to pay about $5kwh of electricity considering in most the world is less than $0.50 kwh.

@@guytech7310The lithium is conducting, but so is the first wall and that seems not to be a problem. Most of the neutrons have to be captured in lithium or a lithium compound. In any case, you are right about the cost of fusion. The complexity of the structure makes that so obvious, but seems to be ignored by all the startup companies.

@@johnh6245 The vacuum enclosture is thin, not a meter thick. Magnetic confinement is dead anyway because its impossible to stablize, because the plasma carries a current which interacts with the containment field causing it to destablize. The longest run to date is about 5 minutes, & was a fluke (not repeatable). Realistically researchers should have built lots of small (desktop size) systems to work on the solviing the stability rather than building huge machines. Fusion researchs appears to be a jobs program & little to do with actual science.

3:26 She mentions Kyoto and net zero in an interview elsewhere. It is interesting that Kyoto is a name quite prominent in the climate narrative. As a mechanical engineer she is probably familiar with the mechanical concept of heat energy. If you hit a rock with a hammer it heats up. Is it just a coincidence that the hurricane and Arctic sea ice extent graphs are identical to the earthquake energy graph going back a hundred years as are the original temperature graphs before they were altered right before the election between a Texas oil candidate and a climate activist to change the long term cooling trend into a warming trend? It is a shame to see innocent people drawn into the climate deception while certain snakes with PhD's laugh and cheer. But their laughing and cheering w.ill turn to wailing and gnashing of teeth.
