These satellite photos show the mine that launched Canada's controversial tar sands industry.
The mine at Fort McMurray, on the banks of the Athabasca River, in cold, remote Alberta, had already been operating for 17 years at the time a U.S. satellite pictured it.
Today the Canadian tar sands are recognised as one of the world's largest oil reservoirs.
The International Energy Agency (IEA) estimates the recoverable oil sands reserves at more than 170million barrels - more than any other nation except Saudi Arabia and Venezuela.
But extracting the resource is both economically and environmentally costly.
This sequence of satellite photos shows how the mine has grown, as the surging oil prices of the past decade made extracting oil from here increasingly attractive.
Even in the first photo, a huge waste storage pond of toxic mine tailings was already visible, but by 2001 operations at the mine had grown massively.
The team's search for the new material, described in the journal ACS Nano,
centered on nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide. The particles were then suspended in a water-alcohol mixture to create a paste. When the paste was brushed onto a transparent conducting material and exposed to light, it created electricity. "The best light-to-energy conversion efficiency we've reached so far is 1 percent, which is well behind the usual 10 to 15 percent efficiency of commercial silicon solar cells," explains Kamat.
"But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future." "That's why we've christened the new paint, Sun-Believable," he adds.

Maybe,one day in the future,we could make it happen.
The technology is there,it just needs a little more research.

I wanted to share this with all of you so that you can actually see how big this operation is, because sometimes hearing something doesn't trigger the same thing as seeing it.
Tom Weis is driving a rocket trike from Canada to Houston, Texas.
His goal: rally opposition to the Keystone XL pipeline route.
“I’m riding to lend my support to all the landowners that live along that proposed route,” Weis said. “We’re fighting to keep that pipeline off their land.”
Weis is a renewable energy advocate for Climate Crisis Solutions out of Boulder, Colo. He started his journey about 40 days ago and has traveled approximately 1,000 miles. He hopes to be in Texas before Christmas.
His vehicle is an enclosed pedal bike with an electric assist motor, which helps with some of the steeper hills.
Weis said this is the second time he’s taken such a journey. Last year, he rode from Colorado to the White House, calling for a green energy moon shot for America, meaning a 100 percent renewable energy grid by 2020.
“I think it’s time for Obama to have his Kennedy moment,” Weis said. “I mean get up and be a great leader.”
Weis said he found tremendous support from everybody he talked to during his first ride last year.
“When I finished that ride, that’s when I learned about this Keystone XL Tar Sands pipeline,” Weis said. “And I couldn’t believe they wanted to go through the Great Plains and over the Ogallala Aquifer with toxic tar sands? That’s insane. We can’t let that happen.”
