100 hours is the general rule of thumb for making grid scale backup of renewables work properly. 100 hours for lithium ion is very expensive. Iron air is 10x cheaper. Itâ(TM)s also 1/2 as efficient, but itsâ(TM)s always cheaper to double your PV output with iron-air rather than try to make it work with lithium ion.

I used to live in a community that had a publicly owned Cable TV network in the metro Boston area. It started off great. Cheaper than the neighboring cities. Better service. Then it went downhill. They didn't have the heft to negotiate carriage contracts with the new channels, so they languished at about 15-20 channels, while everyone else was in the 50-100 channel range (yes, this was a long time ago). When it came time to invest in new infrastructure, things like the senior center, a new high-school football stadium, or nicer bathrooms at the park took priority. Then the service started to suck as "John" got hired to run the infrastructure, whose main qualification was that he was a cousin of the town administrator. Eventually the town got pissed and passed a referendum to sell to the major company in that area (who eventually sold to Comcast).

I pretty much guarantee you that using heated seats generates more service/warranty work on the heated seat system than not using heated seats.

Umm. Actually cows and chickens are not exactly "natural". There's no such thing as a "wild cow" or "wild chicken". They were both genetically engineered through thousands of years of selective breeding. Modern genetic engineering is really no different except that it modifies the genes directly rather than indirectly through breeding.
