Look how smooth and clean that concrete is! Progressing nicely. We’re now waiting on curing for two batteries to hit. A bit more concrete and conduit work so a second pad for other gear (inverters, DC combiners, battery controller, transformers) can be installed. Big show!

All right, back to work, no more Internet news. Gonna finish forming structure today since site has dried up, as you can so nicely see in second image. We’ve schedule concrete pour for tomorrow. Scheduled multiple battery drops in about a month once concrete How it was. How it is.

Battery site prep, land cleared of railroad ties, rocks, roots, etc then filled will conduit - as you can see poking up to the left. Solar to charge said batteries is coming from carport in background. Modules going up soon.

So, we can use solar made electricity to breakdown CO2 into usable carbon and also usable oxygen. Maybe we don't actually 'capture' the CO2? We just make giant solar powered lightening in the middle of deserts and let them somehow just sprinkle carbon to the ground? I am sure someone will buy it...

"This is a major win in a larger effort to synthesize critical materials and battery materials using molten salts," says @berkeleylab.lbl.gov's Mike Whitaker.

Working on a multi-housing facility. The whole site is being refabbed - windows, insulation, applianmces, floors, bathrooms, windows, and everything. I am hopeful that the solar PLUS upgrades will knock the electricity use down to zero. 667 kW, spread across 15 rooftops, and five interconnections.

I remember a few years ago when the massive Chinese solar polysilicon ramps started happening. I assumed I didn’t comprehend the announcements properly, or that there were technical details I was missing…or there was a massive ramp in capacity coming. Well, we’re gonna see at least some tightening.
