Re: tokamak versus fusor efficiencies.

<t>I would say 95% or more, having a few grams of plasma cool down inside the system has little impact of the magnetic field. The magnetic field is basically just electricity so recovering that energy has more to do with storing electricity and how efficiently you want to do that vs any complex issu...

Re: tokamak versus fusor efficiencies.

<t>The problem with your assessment is you can easily recover the energy stored in the magnetic field. They are not doing that because the value of the energy is less than the cost to build a system to recover it. Just like they are avoiding building a steam engine to recover the energy produced wit...

Re: I need a linear solution - or is the universe static

The fly changes shape in the collision, so each part of the fly is moving at different speeds on impact. At the same time in a collision each part of the car is moving at different speeds.

PS: Long time no see.

Re: Idea for Reducing Collisions with Gird using Coaxial Grid

<t>Think of it like the gravitational field around a star: <br/> <br/> As a star's diamiter changes the net field outside the star remains unchanged. <br/> <br/> The math works out the same way with a large vs small diamiter wire the net field is indistinguashable from a smaller wire with the same n...

Re: ITER on NPR

<t>We have discussed this before and I am willing to agree to disagree with you on this but DEMO is designed to be a useful power plant. Granted DEMO is not going to be a cost effective power plant building a coal power plant would be far cheaper but it is designed to be hooked up to the grid and pr...

Interesting idea but…

<t>This assumes “one can drop and trap any ionized particle” but at room temperature each ion is going to be traveling at several hindered miles an hour in a random direction before you accelerate it. Think of it like dropping a machine gun down a mile deep well, assuming it’s not going off everythi...

Re: Ultracapacitors from the minds at MIT

<t>Rockets used liquid H2 in large part because the weight of the H2 fuel container + H2 fuel was lighter than a gas container + gas.<br/> <br/> It's an issue of scale doubling the volume of a container does not double the weight of the container so as you increase the quantity of fuel transported t...
