That's what I love about SuperTopo - when polemics fail name-calling is the option of first resort.
Are you suggesting guyman presented something resembling an argument?
Keep up the good work philo. Some cools stuff here... followed by some ignorant meaningless drivel from close minded fools.
Funny Canadians, from Reilly eh

what's will all the negative waves baby---donald sutherland "kelly's heroes"
TGT BOOKWORM RON RICK get behind progress PLEASE...like my dad used to say don't give me more reasons why you can't do something instead give me one reason why you CAN DO SOMETHING (go SOLAR, GEOTHERMAL, TIDAL, WIND, ALGEA---ANYTHING BUT FOSSIL FUEL----FOR OUR FUTURE!!!!)
Great thread PHILO!!!

A smog-eating street in the Netherlands: Dirty air, beware! (Photo: Science Direct/Los Angeles Times)
The eco-makeover of urban surfaces continues. First came white roofs. Then so-called cool pavement. And now smog-eating concrete.
Yup, sidewalks with a taste for filthy air.
Eindhoven University of Technology scientists have installed air-purifying cement onto a city block in Hengelo, Netherlands, and published the results, which found that it reduced nitrogen oxide air pollution up to 45 percent in ideal weather conditions. This is an average reduction of 19 percent each day.
The concrete, dubbed “photocatalytic,” is made with run-of-the-mill cement sprayed with a chemical—titanium oxide—that neutralizes air pollutants, the researchers’ abstract states.
“[The concrete] could be a very feasible solution for inner city areas where they have a problem with air pollution,” said researcher Jos Brouwers in 2010 to CNN, when the pavement was in its early stages.
So, what’s the world waiting for? Why aren’t urban jungles with smog problems—we’re especially looking at you, Beijing—not jackhammering every piece of old-school pavement and pouring the new stuff?
Well, like most public work projects, it all comes down to cost. Titanium dioxide pavement is simply more expensive than your grandfather’s cement.
But, with further product tinkering and price–reduction, air-scrubbing pavement could be the stomping ground of the future.

I think I've probably posted this video before. However, I really like it so I'm going to post it here as well. It provides a bit of perspective on energy use, as well as a one potential solution. Basically, using PVs to split water (for storage as molecular hydrogen and oxygen) so that it can be recombined later with a fuel cell.
His group has nearly solved one part of this overall "equation" to make this a viable option. More research needs to be done into safe, long term hydrogen storage, as well as more efficient fuel cells.
Discalimer: Don't be turned off by Professor Nocera's slightly condescending demeanor; its a little annoying. However, his message is pretty powerful.

Consider this the 21st Century equivalant of the Wright Brothers first flight.
World's first electric airplane takes maiden flight, could bring down air travel cost by more than a third
May 12, 2014 at 02:29pm IST
London: The world's first airplane completely powered by electricity has successfully taken to the skies for its maiden flight, and could bring down air travel cost by more than a third, its developer Airbus said.
The small experimental aircraft called 'E-Fan' carried its first flight at an airport near Bordeaux in southwestern France, and could prove to be a key step towards greener, quieter and cheaper air travel.
Manufactured by Toulouse-based Airbus, E-Fan measures little more than 19 feet from nose to tail and makes slightly more noise than a hairdryer.
Manufactured by Toulouse-based Airbus, this electric airplane, E-Fan, measures little more than 19 feet from nose to tail and makes slightly more noise than a hairdryer.
Powered by 120 lithium-ion polymer batteries, the plane's first official flight last month lasted less than 10 minutes, though the plane has the capability to fly for around an hour before recharging.
An hour long commercial flight with the E-Fan, according to Airbus, could cost only USD 16, compared to USD 55 for a flight in a petrol-powered plane of the same size, 'Inhabitat.com' reported.
The electric E-Fan training aircraft is a highly innovative technology experimental demonstrator based on an all-composite construction, Airbus said on its website.
"The E-Fan project and Airbus Group's commitment to the field of electric and hybrid research show our vision of future technological developments," said said Airbus Group Chief Technical Officer Jean Botti.
"It will not only lead to a further reduction in aircraft emissions and noise to support our environmental goals but will also lead to more economic and efficient aircraft technology in the long run," said Botti.
Airbus plans to manufacture two versions of the E-Fan. The two-seater E-Fan 2.0 will be a fully electric training aircraft, while E-Fan 4.0 will be used for both training and general flight purposes and will be powered by a hybrid system, the report said.
Airbus Group and its partners are aiming to perform research and development to construct a series version of the E-Fan and propose an industrial plan for a production facility close to Bordeaux Airport, Airbus said.
