Can a reflection from glass-steel skyscraper melt things?

The owner of a luxury car Jaguar XJ parked his sweetheart across the street from the curvy 37 story glass-and-steel skyscraper designed by Uruguayan architect Rafael Viñoly in London  before an afternoon business meeting. Only two hours later, this car was giving off smells of melting and displaying clear signs of damage. The developers of the building who nicknamed it as “Walkie Talkie” for its distinctive shape, agreed to pay for the damages.

So how could skyscraper melt the car? 

“Fundamentally it’s reflection,” Chris Shepherd of the Institute of Physics told the BBC “If a building creates enough of a curve with a series of flat windows, which act like mirrors, the reflections all converge at one point, focusing and concentrating the light.” The curves of “Walkie Talkie” skyscraper acted like a magnifying glass to concentrate the light on only one spot, the exact spot where Jaguar XJ was parked.

Parking has been suspended in the areas affected by the reflect sunlight.

The carpet in a nearby barber shop has a burn mark on the carpet from sunlight reflected off the 'Walkie Talkie' tower.

According to Kheir Al-Kodmany, an associate professor at the University of Illinois at Chicago, Walkie Talkie’s designers forgot about the fact that southern-facing building would generate a lot of heat. If it had been a northern-facing building, it would have been an issues. Luckily London isn’t a very sunny city.

“As we get more shiny, glassy metal buildings, reflected light will become a bigger deal,” John Frederick, a professor of atmospheric science at the University of Chicago says. “The high reflection is good if you’re inside trying to keep intense sunlight out, but if you’re outside, you’ll be the recipient of that reflected light.” Well, sometimes it is just better to walk, leave your car safely parked at home and protect the environment.

The business man's Jaguar apparently buckled in the heat from the 'Walkie Scorchie.'

Stand under my Air-brella

Umbrellas in history

Umbrellas, probably a converted branch of tree,  first appeared in ancient Egypt more than 3 000 years ago and were used mostly for protecting royalty from sunlight. The first waterproof umbrellas were discovered in 11th century BC in China and they were made of leather. Nowadays majority of modern umbrellas are made in China. One Chinese city, Shangyu, has more than 1 000 factories for producing umbrellas! People at that time would be very surprised to see that the invisible air umbrella concept was created. Will it be more useful than the “normal” umbrellas?

This concept uses forced air to repel falling water. It was created by UK industrial design student Quentin DeBaene and a research team in China claims it could create this umbrella by 2015.

How does it work?

The air umbrella uses high-powered jets to emit forced air to repel falling raindrops away from your body, before they can even hit your body. As this umbrella uses ultra high speed fan, the research team has found the way how to charge the batter only for 30 minutes, so this umbrella won’t be useful for a long walk. The retail price is expected to be around $200. I would maybe buy 20 umbrellas instead of this one, half an hour working umbrella. But who knows, it can be changed in the future. See the video here and judge the creation. (via inhabitat, core77)

Be cool, save energy and pay less

While building a house there is always a question what kind of roof to choose, what colour, should it be flat or pitched. When you live in a hot climate the answer is clear. A metal cool roof!

Diagram_1_-_SR_and_TE
A diagram

A cool roof can reflect sunlight and cools itself by emitting the radiation to its surroundings. Isn’t that cool? The roof literally reduces the amount of heat. Two basic characteristics of the roof are solar reflectance and thermal emittance. It is like wearing a white t-shirt on a hot day, it reflects more sunlight and absorb the heat.

 Benefits
  • reducing energy use – as a building stays cooler, it uses less energy for air conditioning
  • reducing greenhouse gas emissions and air pollution
  • improving human’s health and make them feel comfortable – cool roofs prevent heat-related illnesses and deaths
  • extending roof life and lowering roof maintenance costs

metal_roofMetal cool roofs might be one of the solutions for polluted cities. They have significant environmental benefits besides using cool roofs cool the cities. Increasing workplace productivity and decreasing pollution can be achieved by using metal cool roofs. Cool metal roofs actually last longer than standard ones because a cool roof doesn’t heat up that much.

What’s more cool roofs are typically light in colors so they can perfectly be a part of the architecture for those who might consider it as an important feature. As today’s range of cool roofs is pretty wide and there are a lot of manufacturers, it can be a real challenge to make a good choice.

Shanghai Metal Corporation besides other metal and steel products also offers a roof panel roll forming machine or a roof sheet making machine which are widely used for making various metal roof panels.

Meet Solar Farm: The Future in City Light & Power

Resembling something out of a movie, the Ivanpah Solar Thermal is the world’s largest solar power plant located in Ivanpah Dry Lake,
California’s Mojave Desert. Occupying approximately 3,500 acres (14.2km2) and grounded on BrightSource’s solar tower technology, the thermal complex produces gross total of 392 MW of solar power.

Over 300,000 garage-door-size mirrors are used to attract the power of the sun in two dimensions and reflect the sunlight to boilers that sit atop three 459 foot tall power towers. A center of earth location in relation to the sun is used so that each mirror in its solar generating system is precisely aligned.

What is so special about Ivanpah Solar Thermal? Economic, social and environmental benefits are many. With the thermal’s construction 2,636 new local jobs were created, generating about $350 mi in local and state taxes. Clean, sustainable and reliable solar electricity serves 140,000 homes on average in California, while 400,000 metric tons of carbon dioxide emission per year is reduced, which equals to removing 72,000 vehicles off the road.

Not only that, the construction of this iconic project was a breakthrough as it kept the majority of the natural landscape untouched unlike other mega constructions. When BrightSource’s 173,000 heliostat pylons were installed, grading and concrete foundations were limited to the maximum, allowing the vegetation to co-exist within the solar field below the mirrors. The project also accounted with an innovative and customized design; excavators operated in the 130-foot wide no-drive zones, traveling in the same tracks through the solar field and installing between 75 and 125 pylons per day, per machine.

The innovative technology uses the same principal of electricity production i.e. high-temperature steam which turns a solar7conventional turbine, where electricity is produced and transmitted to homes and businesses. The big difference is that at Ivanpah, the concentrated sunlight (and not fossil fuel) strikes the boiler’s pipes and heats the water to create superheated steam. Besides, the technology uses 95 percent less water than competing wet cooled solar thermal plants by employing a dry-cooling process, which uses air instead of water to condense steam. All water used by the steam production cycle is recycled back into the system, or consumed to clean the mirrors, highlights BrightSource.solar8

The Ivanpah Solar Thermal System is “critical to establishing America’s leadership in large-scale, clean-energy technology that will keep our economy globally competitive over the next several decades,” says Tom Doyle, president at NRG Solar. This is the future and the Ivanpah has, for sure, started changing the way we produce and consume energy.
