Generating power at night, the flip side to solar

Nuclear energy has been in the news lately, and its proponents have once again cited the intermittent nature of renewables as a compelling reason to embrace nuclear. They say that only nuclear can wean us off fossil fuels fast enough given the imminent climate crisis.

My argument has always been that renewable technology is still in its infancy and that the sector will explode with new tech in the near future. This post is about one such possible ‘new tech’ – thermoelectric generation.

I can’t explain the science, but I can say that this new direction in power generation would work at night, while solar is unavailable. You can read the complete article here:

The amount of power generated was miniscule, but this experiment sought only to prove that the principle was sound. Scaling up the process and making it robust enough for commercial applications will take a while, but then so does setting up a nuclear power plant.

My money’s on the new tech rather than the old.

Powerline fiasco in Nth Warrandyte

Residents in Nth Warrandyte were without power for 18 hours today. We were without power for 18 hours today, and you’d better believe that we were not amused. But the problem goes deeper than simple inconvenience. The powerlines that keep failing are these  super-dooper new ones:

As you can see from the photo, the new powerlines are much thicker than the old ones. They are also supposed to be much safer than the old ones, and therefore less likely to start bushfires in this highly bushfire-prone area.

Of course, the safest option would be to put all powerlines underground. But that would be expensive, wouldn’t it? So instead we get this half-baked alternative that keeps breaking down.

How do I know the problem is in the new powerlines? I know, because Nth Warrandyte is pretty much the only area in which these new lines have been completed. Nth Warrandyte also happens to be the only area where these long, unexpected, unplanned power outages seem to occur.

Don’t get me wrong – we’ve always had power outages in Nth Warrandyte, for as long as we’ve been here, but never like this. And never accompanied by bangs in the middle of the night. The Offspring saw and heard three explosions last night, just before midnight. Each one briefly lit up the night sky… from the exact area where the problems have been occurring.

The utility company in charge of our powerlines and electricity infrastructure is SPAusnet. This is the same company whose infrastructure may have caused the destruction of homes in Warrandyte in 2014.

The Offspring spoke to the utility today and described the explosions. The response was that ‘it was possums’.

Puleeeeeze. Possums don’t go ‘bang’. And even if it were possums, that would mean that the new, super thick, super ‘safe’ powerlines are even less capable of withstanding the ravages of nature around here. Not exactly reassuring when we’re facing a potentially catastrophic fire season in January/February.

The one bright spot is that the bridge renovations are mostly complete. That gives Nth Warrandyte residents one extra lane across the Yarra River in an emergency. The new Traffic lights are great as well, and both of these measures make living here just that little bit safer. Thanks Daniel Andrews!

Pity SPAusnet can’t get the powerlines right. I wonder how much it’ll cost the company if the new powerlines cause a fire, and they’re hit with a class action suit by all the residents of Nth Warrandyte? I’ll bet that going underground would be seen as ‘cheaper’. Then again, SPAusnet only paid out $648 million dollars in out of court compensation payments after Black Saturday, so perhaps not…

Not happy

Coal vs solar? No contest in China

The world is quickly abandoning coal, the dirtiest of fossil fuels. But that’s not the end of the road for coal mines—in many countries they’re coming back to life as solar farms. Over the weekend, the world’s biggest floating solar project began operating in the eastern Chinese city of Huainan, which accounted for nearly 20%…

Elon Musk wins his bet in South Australia!

As a long time fan of renewable energy, the latest news about Elon Musk fills me with glee. He bet that he could install a megabattery in South Australia in 100 days, and he’s come in ahead of schedule!

The story began last year when South Australia suffered a massive storm that destroyed infrastructure meant to allow Australian states to ‘share’ energy on a huge network. Due to some market manipulation on pricing, and a toothless watchdog asleep at its post [yes, AEMO I’m looking at you] South Australia suffered crippling blackouts, off and on, for weeks.

As the South Australia government is Labor and had invested heavily in wind farms, the Liberals in the national government went on a renewable energy bashing spree without offering up one, single practical solution. And then Elon Musk spoke up and shamed them all. He said that he could create a mammoth battery capable of storing the energy from the wind farms until needed. Then he bet the cost of the battery – $50 million dollars – that he could make good on his promise in 100 days. If he lost, he would carry the cost of the project.

Well guess what? -big grin- South Australia has a $50 million dollar bill to pay!

More importantly, all the dinosaurs in our government advocating for dirty coal power stations have been silenced, at least for a while.

Today really has been a good day. Thank you, Elon Musk. 🙂
