Boron or borane deposits shouldn't be a problem on the chamber wall unless they significantly inhibit cooling. But additional electrode resistance and or impedance will hurt, and either has the potential to make operation sporadic until the accumulations cripple it. An automotive example is a spark ...

If I'm understanding it correctly, the apparent borane challenges are due to the single-shot test environment. Cooling system permitting, the ideal freq is quoted at ~1kHz to keep the fuel in gaseous form. The helium "ash" is automatically ejected as the ion beam headed for inductive conversion to a...

http://focusfusion.org/index.php/site/category/C30/ provides links to Lerner's Technical Papers I and II, which lay out the theory and math in a far more readable form than the patent text. Technical Paper I describes the HMFE in detail. Something about relative motion, but I lack the physics traini...

Far less than obvious is glassing in my south-facing front porch and using a water wall. I might be able to get by on only a few kW and ~10kWh bank capacity.

builditsolar's turning out to be a treasure trove.

Thanx for the compliment. Unlike the majority, I'm willing to invest the time in a series of searches to learn productive search phrases like aneutronic fusion which exposes options to to the D-T's A battery bank is a given, and I calculate 5kWh should run my 30A/240V A/C under San Antonio, Tx summe...

Quite right, MSimon, I'm finding the range. Wind has too many moving parts making some noise in hard to reach places to remain a serious candidate for my purposes. My lot is just barely large enough for a 100' mast, for instance, and I doubt that I could get FAA approval due my location in the local...

Actually I was thinking commercial wind farms, since they always seem to be lots of miles from existing lines and population centers. builditsolar dotcom is a directory of an incredible array of low energy/ solar, wind, even EV info, plans, parts lists, and it looks like 99.9% of those sites are abs...

Have you factored in the cost of transmission lines and on-site maintenance?

Remember, international experts think D-T and have no job security in return for producing fusion before 2030, let alone putting DEMO online.

NK, however, seems to have a lot to gain by making an aneutronic DPF work, since that's the cheapest and possibly the fastest set of experiments.

The 300 hz trigger frequency is under software control. It can range from DC to the expected cooling limits (for now) of 1khz, which would roughly equate to 5MW to 17MW output levels. Over what surface area? I'm skeptical that pulse rate can be maintained over a useful time period. My main concern ...

The entire aneutronic fusion field is about hope with some theoretical and experimental underpinnings to base it on.

The subsidies are still less than the cost of the equivalent capacity in coal-fired new construction, which would have a useful service life extending as far out as 2070. (10 years to permit & finance, plus 50 year op life). Is that less per KWH? Or just less total. BTW is the cost of 100% backup f...

One last note is that a machine cycle is only around 1,020 nS every 300th of a second. In theory. 1uS is an ideal number according to current theory. The 10 to 20nS is a guesstimate based on current understanding of current theory. I agree that's a lot of ifs. That's why there's no PEs in this fiel...

The subsidies are still less than the cost of the equivalent capacity in coal-fired new construction, which would have a useful service life extending as far out as 2070. (10 years to permit & finance, plus 50 year op life). I suspect that the job loss figures are slanted toward short-term alarmist ...

Actually, a lawnmower ICE is a good layman's model for the axial phase, since a high voltage spark (albeit high current as well) ionizes the fill gas, and the output power is pulsed rather than continuous, as the PW aspires to be. http://focusfusion.org/index.php/site/article/anode_erosion_and_elect...
