Re: Snubbers

Richard,

It's the IRFP460, rated 500V.

Snubbers

<t>I know there's a few HV gurus out there, perhaps someone has some <br/> suggestions for replacing standard RC snubbers with something more <br/> elegant. <br/> <br/> I have a HV supply (my own design) that uses a pair of MOSFETs.<br/> 96V DC is applied to the center tap of a transformer, the MOSF...

Re: Is fusion inherently unstable? and should we be glad?!?!?

<t>I am not sure if unstable is the word to use, I would use "inefficient", no "slow" <br/> would be better. Fusion seems to be a process that just doesn't want to <br/> happen. It takes a lot of pressure, literally, for those nuclei to fuse. And, as <br/> you've said, that's a good thing, otherwise...

Re: Soddy's Economics

<t>It would be nice to find a way to efficently make use of chlorophyll for more of <br/> our energy needs. Unfortunately, things like ethanol are roughly an order of <br/> magnitude more expensive than gasoline. Indeed, even the meager ethanol <br/> production today is heavily subsidized, thanks to...

Re: Infrastructure - the joy and end of us all.

<t>I'm not quite as pessimistic as others about the future. I do think way too <br/> many people are spending way beyond their means. All encouraged by the <br/> government, since it leads to increased economic growth. I don't see a <br/> bubble bursting, I just see a flattening of the growth curve....

Re: Beta Decay!!??

<t>The anti electron neutrino produced during beta decay is an accounting <br/> device, to balance the books. It reminds me of Einstein's cosmological <br/> constant. All experimental evidence to date seems to imply something is <br/> required to make the energy balance out on both sides of the equa...

Re: Victoreen glass encapsulated resistors

That's what I thought, Richard, thanks. I've got a 40G ohm resistor, rated for
several KV, on order from Mouser, for turning an electrometer into a voltmeter
that won't load down my circuit ;-)

Victoreen glass encapsulated resistors

<t>Does anyone know what the maximum rated voltage for these resistors is? I <br/> have seen conflicting values. I've done some googling, but have been unable <br/> to find a datasheet online. Are they even made anymore? I have several, but <br/> don't have an official part number, which may be hamp...

Re: Electricity - how much do you use? Pay?

<t>Sorry for the late entry. Here in Maryland (BGE utility) we're on a time of day/<br/> season service, so the rates vary. 3 to 8 cents per kWhr, plus a 2 cent per <br/> "distribution" charge. Lower rates in the winter than summer. Then there's the <br/> $12 a month flat fee as well, which you need...
