First time I have seen this said out loud. Storage replaces transmission lines. The post has good data but gets a bit technical. Add in that batteries arbitrage the current somewhat wild price fluctuations in energy costs (at least in Texas) and you have a wining formula. The post claims battery farms are profitable after the second year. Not bad. It needs to be pointed out that the lunch they are eating is mostly coming from gas peaker plants.

Grid Storage: Batteries Will Win

Been listening to the modern blues classic SUV by Men Shannon. Seems France is finally having a big debate about car size. I hope Mem Shannon is getting some calls from Paris these days.

A map of ERCOT power prices. Interesting to see where power is being produced and where it is being consumed.

Update: ERCOT actually has a nice Grid and Market Conditions dashboard.

What to do with that billion or so empty square feet of office space? Farming! From Smithsonian.

Empty Office Buildings Are Being Turned Into Vertical Farms

i was curious about the cost of mining and refining nuclear fuel. It seems like a very energy intensive process. Turns out fuel is a tiny part of the cost of nukes. The overwhelming cost is the multi-billion dollar price tag of the physical plant itself, which will only last about 30 years. All the same total cost of adding nuclear power is now about 5x the cost of renewables. This says nothing of risks and costs of storing spent fuel. I will let you do your own research. When you do Google you will get all sorts of “sponsored content” explaining the “facts” and “truth” about nuclear power. One caught me eye. I hope this is a prank. I can’t get Alexa to play the song I want to hear. I’m sure as heck ain’t gonna let AI drive my car. Let’s hope nobody lets this stuff anywhere near nuclear power.

Visualising One Billion Square Feet of Vacant Office Space

Needed some blocks of limestone edging for a lawn project. A 4 x 4 x 14 inch block goes for about $3.50 at Lowes. They weigh about 17 pounds. Driving home I saw a landscaping company with a big yard full of hardscaping materials. I called and they said they sold to the public and limestone goes for $350 a ton. I started to calculate cubic feet and before I got too far I realized it was easier than that. Lowes was $3.50 / 17 lbs = $0.20 per pound. The landscaping yard was $350 / 2000 lbs = $0.175 per pound. Probably just going to Lowes.

Two eclipses in Texas in the next few months. Both visible from Austin but north San Antonio is probably the best place to see both, if you had to pick a single location. We should get an 88% annular in October and a tota eclipsel in April. Funny how few people around here have heard about this. I suppose we will be hearing more about it as the time approaches. I’m have heard it may be the largest mass movement of people in history.

New NASA Map Details 2023 and 2024 Solar Eclipses in the US

Yesterday my son topped of his girlfriends car to 100% (from 10%) for $6 at a Tesla supercharger. This is in the Phoenix area. The trick is that it was done late in the evening when tiered electrical rates were low. I figure a similar gas vehicle would cost nearly 10x this price.

This brings up a point that seems to be seldom discussed. The rapid build out of renewable electricity sources such as solar and wind present some unusual opportunities. Solar in particular is being built out to supply power for air conditioning in places like Texas and Arizona. What happens to all of that electric power generating capacity in, say, winter, spring and fall? This isn’t like coal or gas fired generators that can be turned off to save costs. There is no additional cost to solar and wind once it’s installed. They just keep making electricity. What would you do with vast amounts of free electricity? Sounds far fetched? It is already starting. Europe had negative electricity prices at times last week. I don’t worry about the technology side of things, but I do worry that our existing economic structures may have trouble handlimg this sort of surplus, especially in the short term.
