Am I missing something here?
Real Information, rather than just "claims" made to a (and I use the term loosely) "Journalist". And he spent over half-a-million, with another $250k from the State. He claims that he's "got it down to $175k". By that math, he hasn't yet paid his OWN setup off yet (since 2006).

Strizki now generates 21 kilowatts, or about twice as much power as he needs, and sells the extra to the power company, netting him about $25,000 a year.
Is that 21kw "available sustained wattage 21,000 @ 120v", or "21kw-hours per week/month/year", what?

I posted this, as when I saw it, it interested me - being "off the grid" interests me a LOT. But the more I think about it, the more things don't exactly add up here. What is he cracking to obtain the Hydrogen? Water? Is the propane-tank in the background one of the "Hydrogen storage tanks"? What pressure is he storing it at? How much of the generated-power does it take to crack the H2? To compress it? What are his estimated storage-losses? How does he deal with Hydrogen-embrittlement ? (I hardly think a "typical" propane tank was designed for pure H2)

And dozens of other questions (haven't even TOUCHED on the Fuel Cells), none of which are addressed in the article.

Also, if he's making so damn much money off it, you'd think he'd be able to afford to pick those cheap-ass Harbor Freight solar panels up off the ground and rack-mount them at least, perhaps even design a tracking-system to increase efficiency, yes?

Exactly. BUT, will it do-so before it requires major upgrades/overhaul? Solar Cells diminish in output over their lifetime (which actually depends on the amount of sun they get - more sun = shorter life). I don't even have a clue what the membrane-lifespan is on a commercially-available (is there even such a thing?) fuel-cell.

You're right...its all speculation. Its interesting though, and one day somebody is going to come up with something like this that will be worth the trouble.

My cousin lived in a house in Hawaii that was off the grid because there was no grid. They used solar cells and small wind generators to charge a bank of deep cycle batteries. With inverters they could run lights, teevees, computers, etc. The fridge and stove were on gas.

I have a few friends in similar situations. The local continuation school is getting solar shaded parking as they are putting the panels over the parking lot. Passing Safeway's distribution hub in Tracy they just put in two large windmills on the property, Safeway branded even. I'm noticing more of the vertical blade generators on more warehouse roofs. So many are adopting and it will only get cheaper.

The Army is in it in a big way. Google Ft. Irwin and solar.

I was stationed out there for six years. It's a perfect place for a solar farm if the enviro's don't get their panties in a wad like they did years ago about the desert tortois.

You can buy solar/battery system that will run an entire house for around 12K, last time I looked.

Even A/C? That would be a 5 year ROI at my house. Not bad.

Default Energy Independent

If we can become energy independent how will the controlling elite manipulate us. Answer: They can't. This is the last thing they want available to us. What will become of the Military Industial Complex needed to guard the worlds oil reserves?

Solar is about $3.00-$3.50 a Watt nowadays. Figure up your Peak Wattage (everything you'd be running at one time), add about 25-35% to that, and there's what you need for panels. Base the Battery Bank on every single appliance you'll ever plug-into the house, plus 40-50% or so.

VRLSA batteries are Ex$pendy, but worth it vs. Mal~Wart Deep-Cycles. A bank of them sufficient to power your house might take up the space of one or two Armoir's in your garage.....
