When they pull over the way you suggest, do you expect them to do it carefully or do you suppose they will cut off 3 people in their zeal to send their text. I'm betting on the latter. Or maybe they'll tailgate and swerve in and out of traffic to get where they're going faster. My point is that bad drivers are the danger. If they are not texting, they'll be doing something else that distracts them from the job at hand.

pgerassi: Good post. Glad to see someone with common math sense.

Good analysis on the CNG. One of my budies said that they were doing this back in the 70's to cars. Natural Gas is a great way to go.

The cost would be in the trillion dollar range, but would cut the CO2 emissions by a third and even more if a significant amount of cars and trucks would have batteries just big enough to cover the commuting needs of 80-90% of the commuters around 21 miles of range or about 3KWH usable in plug in hybrids compared to the 16-36KWH ones in EVs. They charge at home during off peak and at work during less than peak demand. This cuts CO2 by a quarter, well below the target.

Pumped storage pumps water from a low elevation pool to a high elevation pool storing power. Te water is then released through turbines from the high pool into the low pool generating electricity to meet demand. The quantity of water in cubic meters times the elevation difference between the pools in meters times 9,801 is the amount of power stored in joules. You then divide it by 3,600,000 to get KWH. The biggest project would be to pump water from Lake Ontario to Lake Erie during the night and release it back through turbines during the day. For a 1 meter elevation change in Erie, you store over 10,000 GWH enough to power the US and Canada for 14 hours all by itself. Using it to move off peak power generation to on peak demand only needs about half of that capacity for the daily cycle and the other half to move weekend generation to week day demand. Essentially allows base load plants like nuclear to be the only generation needed with the help of wind and solar instead of the

"pumped storage to time shift generation to meet demand" I'm clueless. What is that?

An excellent response to my article. Thank you.
