Grid Stability with Solar

Grid stability has become an issue here in Texas after last Winter’s Big Freeze. It turns out that independent generators of electricity, such as home rooftop solar, can cause problems on the grid. Since they aren’t under direct control of the grid, non-grid power resources can cause unwanted fluctuations in voltage and frequency. A new generation of controllers fixes this, actually providing better grid stability than the existing grid. A bit technical, but a good read, but there is little reason not to embrace small solar and other renewable installations.

Ever heard of synchroinverters? Grid-stabilizing devices connecting renewables to distributed energy resources

New 1000W Inverter

What with everyone in Texas buying generators and stuff for the next big winter blackout, I finally gave in and bought a little 1000W Inverter. We also bought a little 150W inverter that plugs into the Tesla cigarette lighter / auxillary plug that should run a few lights, well, for weeks if necessary. I decided I wanted a bigger battery operated unit that could possibly run our propane heater. All it needs to do it turn the fan and run the electronics. Probably should try it out on the furnace but I’m just going to wait and see if it turns out to be necessary. My real plan is to leave Texas for a more civilized place that can keep the lights on.

The instructions were a bit difficult to decipher. I’m not exactly sure what “DO NOT DICK HOLD OUT OF SHELL!” means. I won’t do anything remotely like that with any electrical device, so I should be safe.

Mouse Movers

In the modern tech workplace there are all sorts of employee surveillance systems. One tracks PC usage, watching for idle time. One way to defeat this (as all tech workers surely know) is to just move your mouse occasionally. But suppose you have to step away? Turns out there is a selection of Mouse Movers out there on Amazon. From Tom’s Guide.

Mouse Movers make it look like you’re working — and they’re red hot with remote workers

Some Bull

A little Sitting Bull on this quiet Saturday morning. From his speech at an Indian council at the Powder River in 1877

Yet hear me, friends! We have now to deal with another people, small and feeble when our forefathers first met with them, but now great and overbearing. Strangely enough, they have a mind to till the soil, and the love of possessions is a disease in them. These people have made many rules that the rich may break, but the poor may not! They have a religion in which the poor worship, but the rich will not! They even take tithes of the poor and weak to support the rich and those who rule. – Sitting Bull
