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

TGT BOOKWORM RON RICK get behind progress 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!!!!)

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.

"Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources," said Jacobson, a professor of civil and environmental engineering. "It is a question of whether we have the societal and political will."

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, '' 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.

Math anyone?

ENDLESS ELECTRICITY: Here's A Way Of Turning America's Roads Into Gigantic Solar Panels


MAY 14, 2014, 4:32 AM 60,114 80

Solar Roadways
Julie and Scott Brusaw.

There are about 31,251 square miles of roads, parking lots, driveways, playgrounds, bike paths, and sidewalks in the lower 48 states. If Julie and Scott Brusaw have their way, they will all someday be replaced with solar panels.

For the better part of a decade, the Idaho couple has been working on prototyping an industrial-strength panel that could withstand the weight of even the largest trucks. They now appear to have cracked the formula, developing a specially textured glass coating for the panels that can not only bear tremendous loads but also support standard tire traction.

By their reckoning, at peak installation their panelized roads could produce more than three times the electricity consumed in the U.S.

The material could power electric vehicles through a receiver plate mounted beneath the vehicle and a transmitter plate is installed in the road.

Solar Roadways
The project has already received two phases of funding from the U.S. Federal Highway Administration, and last year featured in Google's Moonshot series. They're now incorporated as Solar Roadways.

Right now, they're looking to raise $1 million on IndieGogo to move beyond the prototype and into production. Since announcing the campaign three weeks ago, they've received $112,000.

If you're wondering why they're choosing crowdfunding given the potentially large interest from investors, so have many others. Their reason for doing so is rather noble. As they explain on their website (via John Aziz):

The idea to launch a crowdfunding campaign came to us from so many supporters that we looked into it. We have always been concerned about protecting our vision to implement this in the way that we think will have the most benefit: creating American jobs rather than outsourcing and then adding manufacturing facilities in other countries. That way we could help the economies everywhere providing many thousands of jobs. We have a vision for the way our facilities will be - campus like - with a positive atmosphere. We want to use as many recycled materials as we can and keep our manufacturing process as green as possible. We could go on, but you get the picture. If we can raise enough funds here, we won't have to take on an investor and we won't have to worry about losing our focus. If you like our vision and want to help, we'd be honored to have you in our corner.

Here is an artist's rendering of what it someday could look like:

It could also be used in parking lots:

Definitely something you wish you'd thought of first.

My local REI do that to the parking lot. Pretty cool.

I see more and more solar going up on relatively normal working class homes in my area every year. I can't drive more than a mile in a 10-20 mile radius without seeing residential solar.

Sh#t Home Depot has someone peddling the technology just inside their front door just about 365 days a year.
