I love this article. It starts with: (quote) << Texas is a walled garden of bigotry and hatred. It prides itself on telling people what they can and cannot think, say, or do in the name of freedom. For instance, it is so intent on avoiding federal regulations, it has built an entire electrical grid

So now we can use up all the plastic waste? Just kidding… https://cleantechnica.com/2022/04/15/grid-scale-storage-solutions-plastic-freeze-thaw-battery-edition/
The PNNL claims this phase change energy storage can hibernate for long-term storage. They stated that the room temperature battery must be heated up to 150 deg C to bring it out of hibernation. There are a few problems that I see with this. The battery takes time and power to heat it up to

Arlin Sansome I understand the “echo chamber” and “silos” that social media users get caught in. But putting all of that aside, the climate change deniers are being paid for by Big Oil. This is exactly the same as big tobacco did to deny for decades that cigarettes cause cancer. There was *no* social media

Watson’s Buzz Beeper I built this Buzz Beeper to find out if an audible tone could be used for sending simple commands, like turn on. Recently I built a microphone preamp with a bandpass filter that can detect my whistle. But it can be triggered by loud noise. So how about I generate a tone

Chris Gillespie The “net energy” is the catch. One **must** consider the LCOE – levelized cost of energy. If the fusion reactor requires that the energy used to fuse *and* make the fuels is greater than or equal to the output of the reactor, then the fusion reactor is a liability and is wasting energy.

Those $5000 (in this case Ford) dealer markups are just fine – they force their prospective customers to vote with their feet and move to buying a Tesla. Just one more nail in the coffin of dealerships – they don’t have many years left before they will be gone. Also, if the dealer doesn’t advertise

For more than a year during this ‘chip shortage, I’ve constantly heard, Elon Musk should build a chip fab. Build a chip fab! Build a chip Fab! Over and over again. It turns out that the chip shortage is actually a wafer shortage – there are not enough 200 mm (8 inch) wafers to make
