New York Times (and others!) fumble economics of technology

In a recent article on the zinc-air battery, the New York times says that the breakthrough in cost for this battery is getting it below $100 per kilowatt-hour.

This confusion may come from the NantEnergy website, where there is a typo: they use kWh where they mean kW and journalists apparently including the New York Times, L.A. Times and Associated press all expanded this to kilowatt-hour, which is clearly ridiculous.

The actual average kWh price across the US is 13.5 cents ... and where I live in Washington state, it's more like 9.5 cents.

That point out of the way: if they can really deliver battery storage for $100 per kW, that's terrific; send me 10!
