Probably Not The Place For This

Eli has been watching the reports on today's Senate hearing which features the Ted Cruz - Sally Yates death match.  The general feeling is that Yates did to Cruz what Macron did to Le Pen.  However, rather than getting too deeply into the legal parts of their interchange, the Rabett would like to point out that Yates READ most of her initial answer to Cruz (starting at 1:49 in the video below).

She was clearly prepared for the question.

You might ask what little birdy whispered in her ear, well, let's go to the video from three months ago

Somebunny was paying attention.

The New York Times approach to climate change

Behold the CrapWaffler, the writer that the New York Times thinks is a contribution to the climate change debate. It's what happens when you hire a climate denialist with the implied condition of employment that they can't completely lie about climate change, but merely smear uncertainty and misdirection about undertaking reasonable action (and Stephens still managed to get important things wrong).

The New York Times thinks it has added to the breadth of discussion on climate by getting as close to wrong as possible while not saying much of anything.

Stephens is shocked, shocked, that people would accuse him of "closet climate denialism". The term denier fit Stephens perfectly in 2015 when he wrote that temperatures would be about the same in 100 years, unless he was lying at the time about what he believed. It would be helpful if he now said his beliefs had changed, but all we get instead is crapwaffles.

I often read Razib Khan, an old-school Burkean conservative who also writes a lot about science. Several years back the NY Times hired him and then quickly dismissed him - he had unwisely associated with some simply vile racists, and guilt by association was enough to deem him unacceptable. I disagree, but to think Stephens, whose range is from wrong to crapwaffle, is better just tells you something about the Times. I recently subscribed to the Washington Post instead.

So skip Stephens, and read Razib to see what a thoughtful conservative would say.

P.S. And fellow bloggers, a reminder to add "no follow" whenever you link to Stephens. I'm pretty good about that when linking to denialists

Renewable Energy and Creative Construction

One of the weirdest flips in an exceedingly weird year has been the usual suspects going into complete meltdown about there now being extended periods where there is so much renewable energy from wind and solar and hydro that they are not just giving it away, they are paying you to take some of it.

Electricity has become like zucchini at the end of the summer, when gardeners leave a few hundred pounds on your doorstep, ring the bell and run.  Remember when the fusion and fission folk were talking about too cheap to meter, it's now a "problem" for renewables.

In any case, when there is money blowing in the wind somebunny will make money while the sun shines, and indeed this is a classic capitalist system opportunity, that somehow all the Randians and Trumplets let alone your average garden variety Bret Stephens don't appear happy with.  If there is a price differential arbitraging the electricity price is a great way to get rich and the technologies already exist.

There has always been a price differential between wee hours of the morning and the peak demand daylight hours, a differential that many industries have taken advantage of.  The guys with the green plastic eyeshades are no bunny's fools
Kentucky Electric Steel spends a lot of time and money trying to control our electric bill, over $2 million spread over the past eight years. This has reduced energy intensity from 743 kWh per billet ton in 2002 to 480 kWh per billet ton today. That represents an annual savings of over $600k with just our night-time operations; the savings would be even more if we ran during on peak hours, except that the higher power cost would eat them up! 
Aluminum smelters in Germany are already lapping up some of the freibier by using the molten metal as an energy storage medium from whose cooling they can draw power
By varying the rate at which the metal is produced, the plant will be able to adjust the power consumption of the 290-megawatt smelter up and down by about 25 percent. Trimet can soak power from the grid when energy is cheap. It can then resell the power when demand is at its peak. The company can temporarily reduce its power consumption by slowing the electrolysis, cutting the energy drain.
Using stored thermal energy is really old technology.  Ice houses that lasted through the desert summer have existed like forever in Iran and storage of heat from the summer to use in the winter is also a Canadian reality (tip o the ears to Andy Skuce )
The first of its kind in North America, DLSC is heated by a district system designed to store abundant solar energy underground during the summer months and distribute the energy to each home for space heating needs during winter months.
For decades large building have built tons of ice at night when electricity is inexpensive and used the ice to cool the building during the day.  Going by the name of ice storage air conditioning, the technique is now moving into residential units.  Eli first became aware of it in the context of labs using large ice systems for to supply coolants for lasers.  Storage heaters are also coming back driven by the low cost of renewable thermal.

So the next time your electric provider tries to leave some zucchini on your doorstep, smile and use it to charge your batteries, heat or cool your house or some other creative construction.
