NZ to Virginia: damn, that's a long flight!

>Are you thinking micro-inverter panels or a full grid tie with backup batteries?

Well, I just don't know! It seems there is a lot to learn about the pros & cons of each system.

I don't like batteries, I know that much. So I'm leaning towards using the ...

Hi Everyone,

Apologies for the long silence. I've been in my new place for 10 months now, and it is finally starting feel like home (although I only unpacked the fusor a few weeks ago). The house was built before World War II as a barracks for the housing of Royal Air Force personnel, around 1935 ...

Yes, that's right. There are two ways of going about it: either drill the piece entirely under water, or stop frequently and add water. The second approach is more effective as it creates an abrasive slurry that does the actual cutting. You really need to keep the drill bit cool though, otherwise ...

Doug,

The silver activation numbers are proof enough for me. And I think I understand what you are saying about Paschen's law allowing you to bring the grounded copper pipe so close to the grid, but I'm trying to visualise the electric field in this area. Surely the field intensity must be higher ...

Quantum wave theory aside -just a quick note about cellular replacement:

Biology operates at a higher (molecular) level – ‘who we are’ is contained within the human brain by specific connections between the brain cells. The contact surfaces of the neuronal projections (axons and dendrites) are ...

This looks very promising Doug! Nice work. EMI immunity is definitely worthwhile in this environment!

It would be nice to know that each head has an approximately similar interlayer thickness/sensitivity if we are going to use them as a standard.

I guess you could supply the button head with a ...

Yes, absolutely - it is not enough that it 'just works' or 'sometimes works', it has to work reliably every time and preferably have some spare capacity. I feel that in order to make progress we need fusion 'at the flick of switch' (close to what Doug has achieved), systems that we can rely on to ...

Yes, actually I am rebuilding the stack and the driver. The stack is the priority though, and is nearing completion.

Some of the capacitors have small cracks and chips in them, which is a bit of a concern, but I will power up slowly and see how it goes.

I have tripled up the diodes, and will only ...

A quick update on CW stack redesign progress:

Only one major change to this design - I recently received an off-forum suggestion from an ex-FusorForum member suggesting that some of the large capacitors could be redeployed:

"The first capacitors on each side arm, but only the first, hold back half ...

I am currently modifying my Cockroft Walton multiplier. It has too many stages (9) and lots of apparent voltage, but not much under load. So I'm reconfiguring it using the parts that I have, for more current and a lower voltage.

The small caps are 3300 picoFarad at 10KV, the larger caps at the ...
