Comment Re:Renewable Energy vs Waste of Energy (Score 1) 626

Well, I suppose it's reasonable to consider Oz as a benchmark for worst-case scenario. Still, I maintained running water and refrigeration for 3 days while all the mains-connected folk had to throw out their perishables, and flush their toilets with buckets of water from rainwater tanks - those who had tanks, that is.

It's not a gimmick when the cost of connecting to the grid is more than the cost of an off-grid system - it's simple economics. BTW, we recently had a cyclone go through the district (South-east Queensland, Australia) - mains power was out all over the place - including services like water - so people "on the grid" not only didn't have electricity for days (goodbye to the contents of your fridge/freezer), they didn't have flushing toilets. We "off the grid" types managed to avoid such unpleasantness.

That's an interesting point - I have some 55 watt panels on the roof that are over 20 years old, and probably not producing at the rated spec anymore. I want to replace them with newer technology panels - I wonder if the rare earths in the old panels make them a worthwhile "trade-in" option? Anybody know much of the various elements are present in panels?

Switch to LED lighting. Leave the manufacturing energy cost out of the equation for the moment and just concentrate on the day-to-day energy consumption of a traditional tungsten-filament bulb, compared to a halogen equivalent, compared to a CFL, compared to an LED - all with similar or identical output in lumens/sq. metre. The energy consumption drops off dramatically. Of course you now have to consider total energy costs over the lifetime of the device including manufacture, transport, distribution, etc, and how long it will take to deliver a nett "profit" in energy consumption compared to previous technology. My own experience is that reducing your daily energy consumption makes a surprising difference when totaled over a year.

Submission + - NASA awards contract to Bigelow Aerospace for inflatable ISS module (gizmag.com)

cylonlover writes: NASA has announced that it has awarded a US$17.8 million contract to Bigelow Aerospace to provide the International Space Station with an inflatable module. Details of the award will be discussed by NASA Deputy Administrator Lori Garver and Bigelow Aerospace President Robert Bigelow at a press conference on January 16 at the Bigelow Aerospace facilities in North Las Vegas. However, based on previous talks, it’s likely that the module in question could be the Bigelow Expandable Activity Module (BEAM).

Submission + - JFK in Oregon: The Story of Two Polaroids (time.com)

harrymcc writes: "Last month, I stumbled upon two black-and-white Polaroid photos of John F. Kennedy in an antique store in Portland, Oregon. As a Polaroid nut, I had to have them — and thanks to the Internet, I was able to determine that they were taken on April 23, 1960 in Medford, Oregon, during Kennedy's campaign for the presidency. Better yet, I tracked down the other guy in both photos: Wally Watkins, a Medford resident who's still very much with us, and who used his own Lincoln convertible to drive JFK in Medford's Pear Blossom Festival parade that day."

Good point - I think it's local, though. I won a consolation prize, once - 2 smoke alarms, a fire blanket, backpack, cap, AND a Garmin Nuvi!. When the next call came I told the caller I'd be happy to buy double tickets, because of the prize. He started talking about what a great little package of items it was, and he had been given the package for some reason - so that makes me think it wasn't outsourced to a city call centre.

2 reasons. The size of the area to be burnt, and funding.
 
When you have limited funds, you have to be very selective where you spend it doing this years' choice of burns. Rural Fire Brigades (at least here in Qld) have to do a lot of fundraising to stay afloat - they're volunteers, and one of the few charities I always support when the phone rings to sell me raffle tickets.

Comment Re:Nuclear Power, now, and put it in my backyard (Score 4, Interesting) 313

I like your open-minded approach - no, that's not sarcasm, I mean it. Yes, electricity from nuclear fission is cleaner overall than most other so-called baseload sources. It's still scary when something goes wrong - it doesn't matter about new designs, assurances, technological advances (which ARE impressive) - human fears are a factor, and must be dealt with, whether based on solid evidence, or FUD from greenpeace.
 
I live off-grid using subsidised solar PV, and a petrol generator for backup when it's rainy. If I was really strict about appliance usage when the weather is less than ideal (e.g. turn off the kids' computers), we wouldn't need the generator very much at all. Let's put aside the environmental impact of manufacturing solar PV for the moment, and focus on whether it's possible to live off-grid with solar PV. Is it possible to continue a high-energy-consumption lifestyle with old-style incandescent light bulbs, air-conditioning, electric clothes dryers, electric dishwashers, electric coffee-makers, electric ovens and stovetops? No, it's not. Is it possible to minimise your consumption of fossil fuels and still enjoy life? Hells yeah. No aircon, occasional use of the clothes dryer run directly off the generator, wood-fired stove (also supplies hot water and heating), hand-wash dishes while listening to internet radio, 2-3 major appliances at any one time, e.g. 2 computers and a washing machine, or vacuum cleaner and washing machine, etc. It can work, if you want it to. Right now, I'm typing this on a laptop, on a sunday evening, listening to internet radio (B.B. King, if you're interested) via another laptop amplified through an old boombox, my daughter is watching some silly movie on Nickleodeon on a 55" LCD TV, sourced via a HD decoder from a satellite dish, my wife is playing minecraft on her laptop with an external 24" LCD screen, and my son is doing the facebook thing on his iPad - it's about 5:45pm, so house lights will be coming on soon - they're a mix of 24VDC halogen, and 240VAC CFL. All it takes is willpower, and (gratefully acknowledged) Govt subsidised PV - yes, I DO pay my taxes, BTW. Mind you, even if it the gear wasn't subsidised, it still would have been cheaper than getting the mains extended to my place.
 
Not the right solution for everyone, obviously, but saying it can't be done is simply not true.

'bout time somebody mentioned Oz. We gots big flat expanses, and bucketloads of sunlight for the PVs needed to offset the energy needs, everyone likes us, and the native critters can provide security services.
 
Oh, and we've got Michelle Jenneke to keep the lonely scientists entertained.

Oh god yes - she's such a national treasure. Any politician, no matter what else I think of them, gets a bonus point for being prepared to look silly on national TV. Intentionally silly, that is. Not when spouting party policies. And Barnaby Joyce just makes my day whenever I see him giving a sound bite. I can't tell whether he's a master troll or just an idiot, and that's not sarcasm - I've actually heard some well-reasoned words escape his lips.
 
Offtopic - anyone surprised about the outcome of the Peter Slipper court case?
