"… the [538-page plan ]calls for selling only zero-emissions vehicles by 2035,…
I would humbly request a working test of an aggressively competitive 300 mpg (electric equivalent) transit system with excellent coronavirus protection by 2023.
“… net-zero greenhouse gas emissions from the power sector by 2040, …”
I have three different on-demand electric generating systems for different purposes. I’d be happy to see all three prototyped within three years.
Hydropumping is when you force water to a higher pond with PV or wind and then let it back down for on-demand power. I want to do the same thing with many satchels of rocks or other clean fill, except at lower cost, without the environmental issues and with less energy lost, maybe at a storage cost of 3 cents per kilowatt-hour. That and PV would undercut natural gas and deliver power at night.
I have patent #8823197 for improvements to a mountainslope solar chimney. Costs per kwh of nighttime electricity are rock bottom but I prefer to see a fairly tall mountain, 2000 meters in elevation would be good enough.
Solar power towers are getting in the range of 3 cents per kwh out west. I can do better, and I can completely eliminate their serious bird killing problems. Storing the solar heat is the key to nighttime generation.
