Nuclear fusion and bernouilli's principle

Click For Summary
SUMMARY

This discussion centers on the application of Bernoulli's principle to nuclear fusion, specifically the use of funnel-shaped targets instead of traditional spherical ones. The proposal suggests that lasers could direct deuterium into these funnels to increase speed. However, Dr. Gregory Greenman refutes this idea, emphasizing that Bernoulli's principle indicates that faster-moving materials result in lower pressure, which is counterproductive for achieving the high-pressure conditions necessary for fusion. He asserts that stagnant deuterium under high pressure, as achieved through spherical implosion, is essential for successful nuclear fusion.

Could Bernouilli's principle be used to cause nuclear fusion.Instead of spherical targets for lasers to strike what if we had funnel shaped targets - lots of them - with their apices all meeting in roughly the same region of space.Lasers beams could strike the wide ends of the funnels and force deuterium into the narrower parts of the funnels where it would pick up speed. Or would there be too much back pressure?

Rothiemurchus,

You don't want to have the deuterium pick up speed. Recall Bernoulli's Principle states that
the faster the material moves - the LOWER the pressure. You don't want fast moving LOW
pressure deuterium.

You want to have HIGH pressure STAGNANT deuterium. That's what a spherical implosion
gives you. Forget Bernoulli.
