Fusion energy producing devices

The above link is to the sustainable energy page of the finbliz web site, which now contains summary information and links to ITER, Focus Fusion, and Z-pinch sites. IF one of these concepts can be made to work on a large and economical scale, then truly the world will never run out of energy.

My assessment? ITER's large Tokamak plasma containment device will work, but because of its huge size, complexity and costs, will it ever do so economically? Focus Fusion's "Dense Plasma Focus" device almost seems "to good to be true", but its compact low-investment machine is certainly good from an economic perspective. Z-pinch at present can not fire repeated pulses, so this issue needs to be solved. Would I keep working on these concepts? Most definitely yes, as the stake is monumental. Bill
