Comment Re:I'd be open to it, but good luck with everyone (Score 1) 430

A "minor" release (and don't state it like it's a fact just yet) from an earthquake more powerful than design criteria does not make me think "Nuclear Power is Safe" nor even "Nuclear Power is Unsafe." It makes me question the design assumptions. Never mind what was known at the time. With benefit of hindsight, the design assumptions were clearly wrong.

So. Given what we know now, is it a correct assumption to pay the extra required, such that at-risk plants be designed to tolerate common-cause failures devolving from a magnitude 9.0 quake and related tsunami? That's really one for risk analysis economists to decide, but the consequences of failure are so unbelievably expensive, that my knee-jerk assumption suggests that it is not. The big problem is that the consequences are so expensive that they cannot be other than mostly externalized.

You're being unnecessarily adversarial, and I wonder what your agenda is. It seems important to you to dismiss the idea of low-consumption off-grid living. In any case, I'm not advocating living like this in the 2000s. Just commenting on my amusement at the article conclusions, given that it is and was possible to run a minimalist household with a single wind generator with inefficient 1970-era technology.

Yes, the propane fridge sucks, but food refrigeration is pretty important. I'd be curious if you can back up your implied claim that a small, well-insulated propane fridge generates a lot more carbon than the huge, inefficient electrical monster most city-dwellers own.

As far as the rest of your questions go... The propane/electricity carbon balance was not significant in the 1970s, as a high proportion of power generation in Ontario was from coal and gas. The batteries were telco discards, rescued from the landfill. Those lights provided entirely enough illumination -- a 12v 100w incandescent bulb provides 100w of illumination, same as a 120v one -- and this was a home, not an art gallery. The building was a 1200 sqft 2 story detached house with (ineffective!) passive and active solar heating features. Cooling was provided with open windows.

Heating was provided with a high-efficiency woodstove. And before you start on your chemical-of-the-week schtick again (still carbon, yes?), the growing bushlot made the property a net carbon *sink*.

Sure, if you'll make an effort to restrain your incredulity and be a little more polite.

Propane stove and fridge. 1500 kg lead-acid battery bank. About 15 12v incandescent bulbs ranging from 40w to 100w. Computer on an antique and inefficient square-wave inverter, small b&w TV, two stereos, and occasional power-tool usage. The only hard part is the fridge. Propane fridges really suck, or they did in the 70s.

Apart from that, it's pretty easy if you're willing to live small. Not everyone wants to live like a USian with a strong urge to max out their credit cards on electronics and appliances.
