Energy grids running on renewable energy sources need storage. TheTaum Sauk Hydroelectric Power Stationin Missouri works exclusively on pumped-storage. Pumped hydro is effective, but needs lot of water and a suitable site for storage. Can the same principles be applied without using water as the prime mover? Open panels show the electronics of the ARES shuttle. ARES Founder and Director of Technology Development Bill Peitzke is at left and CEO Jim Kelly is at right....

Although its just 13 km from the nearest road, no cars can reach it. Supai is the only place in the United States where mail is still carried out by mules. Photo credit Havasupai means “people of the blue-green waters.” The Havasupai tribe is the smallest Indian Nation in America totaling about 600 people.

As he grew older, the seizures became more and more frequent and more violent. At first, his vision would become blurry but eventually clear up. Curiously, it wasnt until John Bramblitt went completely blind that he started to paint. Bramblitt learned to distinguish between different coloured paints by feeling their textures with his fingers. Bramblitt has never seen his wife or his son but has painted remarkable portraits of them....

A crowd of almost a thousand figures stand silently on a field near the road. In the morning with light behind them, this motionless army appears morose, even menacing. They were first displayed in 1988 in a field in Lassila, a neighbourhood of Helsinki. Passing motorists always wonder what precisely is the artist’s idea behind the Silent People. But Reijo Kela refuses to provide any explanation, forcing people to form their own interpretation....

If you chose the later, than any place on the surface can logically be the center. At least, this is whatmany towns, especially around North America, believe in. The section weighs 3,000 kg and was bought at an auction in 1989. There is also a Wall for Ages where visitors can have their names engraved for $300. The Museum of History in Granite is alone worth visiting. The day the post office was officially opened over 2,300 letters were mailed....

That was before Norway started building an extensive data pipe of tunnels. If a mountain stands on the way, they will drill through it. A fjord is too long to build a bridge? Tunnels make driving through the country much more easier than taking circuitous routes along mountains or ferry hopping. According to onesource, the count is even higher above one thousand. For a country the size of Norway, thats an awfully lot of tunnels....

The area had prehistoric quarry which later became a mining site. He even dug an artificial lake for the spa named Lake Tuendae. Springer claimed to be a physician and a Methodist minister, though he was none. Springers downfall came when he tried to push his luck a bit too far. The federal government got wind of his operation and evicted him from the site. Most of the concrete buildings still stand, repurposed as a research facility....

“High dwellings are the peace and harmony of our descendants. Remember the calamity of the great tsunamis. The waves stopped just 300 feet below the stone. Many carry simple warnings to drop everything and seek higher ground after a strong earthquake. Others, such as the ones in Aneyoshi, specifically instruct where to build homes and where not to. Unfortunately, in the bustle of modern life, many of these ancient warnings were forgotten or simply ignored....

The Boy with the Leaking Boot is a recurring theme of statues that appear throughout the United States. There are at least 25 documented examples, and probably hundreds more. Yet, nobody knows who the boy is, and why does he hold aloft his leaking boot. Some believed that the boy was a real Italian newspaper seller who drowned. Others said he was a Civil War drummer boy who brought water to wounded men in his leaky boot....

One of these initiatives is the construction of a massive hillside escalator. “This should be a symbol of city transformation and peace for Comuna 13.” Innovations like the escalator are turning the Colombian city into a showcase for leading urban planning ideas.

Historical accounts claim that eight horses could ride side by side over it. Some claim it to be the second-longest continuous wall after the Great Wall of China. Many fondly call it The Great Wall of India. From the palace top, it is possible to see kilometers into the Aravalli Range. The sand dunes of the Thar desert can also be seen from here. Legend has it that when the fort was being built, Maharana Kumbha encountered numerous construction difficulties....

By the time the drops hit the water below, they’d started to solidify. The water caught the shots and cooled them further. Watts applied for a patent and was granted. Soon, shot towers started appearing all over England and Europe. In subsequent years, shot towers advanced technologically and spread across the United States and Europe. Steam elevators replaced staircases, cast-iron frames buttressed brick walls, and mule-drawn carts made way for rail lines....
