both onion and ion exit beam could yield raw voltages from 50 kV to 2 MV depending on actual circuit design

Outstanding! Several standard US transmission voltages are in that range!

Okay, that would mean that cooling and transformers can be off-the-shelf parts. (The quantum dots being an upgrade possibility.)

Cooling should probably budget one shipping container and an onsite water supply for now. Could get better quickly. (or could already be better and I’m just unaware of the fact… 🙂 )

And depending on exactly what the box outputs in terms of power and the desired specifications at the work site the transformers could range in size from 1/4 to 1 container. (lot of leeway in there but there’s a lot of options…)

A dedicated engineering solution might even get
the whole shebang into two containers including the DPF but that’s not off-the-shelf…

And the work site may already have cogeneration and/or HV transformer capabilities on hand… in which case there might need to be only one container with a DPF and some spare ducting and cabling stuffed in with the DPF gear.

But we want to find out what is required for a DPF to operate on its own so let’s assume that we’re planning for either an initial power situation with little to no infrastructure in place or an emergency situation with damaged or unknown infrastructure… so let’s examine what I hope is a representative sample of the competition…

Hmmmmmmm… off the bat a DPF appears to be at least competitive… while the gas turbine easily sheds most of its heat by expelling its exhaust gases it must burn fuel and pollute to do so. Also it uses up volume for noise control.

I wonder how a DPF’s vacuum pumps would do in a comparison of noise and moving parts maintenance as well…

The T-60 produces the power to industrial specifications so no extra transformers needed?

Would attempting to meet or exceed the T-60 specs be an appropriate target for a first cut at a DPF installation?
