This New Breed of Generator Can Run on Almost Any Fuel

This New Breed of Generator Can Run on Almost Any Fuel:

It doesn’t matter that it’s been raining for two weeks because your utility is tapping into ammonia produced with last summer’s sunshine. It’s consuming that ammonia in a linear generator.

The linear generator can quickly switch between different types of green (and not-so-green, if need be) fuel, including biogas, ammonia, and hydrogen. It has the potential to make the decarbonized power system available, reliable, and resilient against the vagaries of weather and of fuel supplies. And it’s not a fantasy; it’s been developed, tested, and deployed commercially.

The cofounders of Mainspring Energy, of which I am one, spent 14 years developing this technology, and in 2020 we began rolling it out commercially. It is currently installed at tens of sites, producing 230 to 460 kilowatts at each. We expect linear generators at many more locations to come on line within the next year.


Microsoft’s New OpenAI-Powered Bing — Pixel Envy

Microsoft’s New OpenAI-Powered Bing — Pixel Envy:

Microsoft announced today’s event unveiling these developments midday yesterday, hours after Google announced its efforts in the space, as it has done before. I am not sure whether to read this as panic or excitement, though Meta’s caution is notable.

Late last night, I assembled a series of links with commentary about this nascent field. I think it holds up. While Microsoft may be the first to play its cards, I cannot imagine Google will not quickly respond.

After a lot of research, consultation of folks with exterior sign experience, and personal testing, I went with the artist acrylic paints above, although other very good brands would work as well. These pigments are all from the larger list recommended by Martin Wenham in his book. I’m trying to learn more and more about color theory and practice and Martin is a master. I mixed the brownish color from the first three, and the green from all four. Professional artist colors like these list the specific pigment used, along with the opacity (vs transparency) of each color. Notice the opacity square for each of these pigments is a completely black square, meaning very opaque/solid. Also, all of these pigments have the highest lightfastness rating, so they will be naturally resistant to fading. I thinned my mix just a touch with an acrylic medium to the consistency I wanted to work with.

[Well done!]
