I'm not exactly sure if you're being ironic or not so I'll proceed by assuming you're serious.

A battery or ultra-capacitor is simply a device that stores energy. A heat tank is also a device that stores energy. They're basically both batteries. The real question is which method is the most efficient. Likely, as they are using the sun to generate heat, it's more efficient to store that energy as heat before they need it.

If this company thinks they can operate this plant, I see no reason to stop them.

I see no reason why you keep mentioning birds like it's some sort of game changer. In Canada between 16-42 million birds are killed each year through collisions with buildings. Should we stop building houses? North America wide that number may rise as high at 1 billion. Not to mention that you conveniently left out the death toll on all animals from pollution/habitat loss from the fossil fuel generators which far exceeds the numbers of 'streamers' that these plants will generate.

Improvements on all fronts, should not be abandoned because those improvements are not perfect.

Comment Re:How is electric clean? (Score 1) 230

In some places electricity generation is dirty. But it doesn't have to be. As renewable generations continues to accelerate, electric cars become cleaner and cleaner. They also provide interesting possibilities for symbiosis. Cars that can mop up the excess energy produced by variable generating systems like solar or wind when generation is high but cut back when low.

Instead of discounting electric cars because some places use coal as part of their generation mix, why don't you advocate for the phase-out of coal generation?

Submission + - Wind power now cheapest energy in UK and Germany, no subsidies needed. (

Socguy writes: Bloomburg reports wind has now crossed the threshold to become the cheapest source of energy in both the UK and Germany. Notable because this is the first time it has occurred in a G7 country. In the US, wind and Solar have started biting into the capacity factor of fossil fuel driven plants as generators opt to idle plants more often in favor of nearly free renewable energy. This is leading to changes in the lifetime profitability of those plants.

True, true.

I still enjoy the original for the reasons outlined in this article, it's like a time capsule for thought. Side note: I'm glad that Abrams switched to Star Wars. He was so right when he said that he didn't get Star Trek, specifically that Trek wasn't about guns.

Sigh. Yes, few individual events can be attributed directly to climate change but that doesn't mean that climate change is not playing a role in those events. We can easily compare frequencies and energy levels of events like storms to past measurements in order to see trends over time (more storms of larger size in this context) and that's one way you see the impact of climate change. Kind of like how nobody drops dead immediately after lighting up a cigarette but we have gathered enough statistical evidence to know that smoking makes just about everything about your health worse including chopping years off your life.

The universe is not 'skeery', it's following the laws of physics. The scientific debate about whether climate change was real ended in the 1980's because by that point the evidence for it was clear and compelling. Since then there have been billions spent by those with a vested interest in delaying action on climate change to disprove it but thus far they have been unsuccessful. They will likely continue to be unsuccessful because the evidence for climate change is so overwhelming that it's difficult to even make up a semi-plausible theory that can explain everything that we're now observing. Instead they wage their proxy war through the editorial pages and on internet forums.
