Comments Off on New rooftop cooling tech beams excess heat into outer space

Heat rises, and, with a little help from scientists, can soar as high as outer space. A team at Stanford University has created a roof-mounted system which cools buildings, without the need for electricity, by incorporating solar panel-like machines that beam heat into the cold expanse of space. This system, known as radiative sky cooling, is seen as an early step to developing a full strength system to cool buildings without the need for an external energy source. This could prove enormously beneficial in dealing with the impacts of climate change (a warmer planet) while reducing its causes (lowering emissions). Shanhui Fan, professor of electrical engineering at Stanford, and his team have been working on radiative sky cooling since 2013. Their recent research has demonstrated that the radiative sky cooling system is capable of lowering the temperature of flowing water to below that of the air around it. While Fan and his team have specifically harnessed radiative sky cooling for air conditioning purposes, this process is something that occurs naturally. “If you have something that is very cold – like space – and you can dissipate heat into it, then you can do cooling without any electricity or work. The heat just flows,” explained Fan. “For this reason, the amount of heat flow off the Earth that goes to the universe is enormous.” Related: Massive new data center to be built in chilly Norway to offset energy use The primary obstacle to achieving a net-temperature decrease through radiative sky cooling is the heat received from the sunlight. To solve this problem, the radiative sky cooling system at Stanford incorporates panels that are coated with a multilayer optical film, which has the ability to reflect up to 97 percent of the incoming sunlight . Using data gathered from small-scale testing, the Stanford team projected that a full-scale radiative sky cooling system would result in an 18 to 50 percent reduction in the amount of energy needed to cool a building. To further develop the concept, the team has started a company called SkyCool Systems and plans to incorporate their system into refrigeration and air conditioning models, with a particular focus on cooling massive data centers .

China plans to build nearly 300 new eco-cities

Comments Off on China plans to build nearly 300 new eco-cities

China broke ground on a 40,000-tree-filled Forest City earlier this summer – but apparently one isn’t enough. The country, infamous for their environmental pollution , plans to construct 285 eco-cities , according to Forbes. But what exactly an eco-city constitutes – and the standards to which it will be held – is still in question. Individual buildings can be held up against LEED standards, or even China’s Three Star system. But Forbes pointed out there’s no such criteria for entire cities . The publication quoted Austin Williams, Jiaotong-Liverpool University professor and author of a book on eco-cities, who said, “There is no definition of an eco-city, which makes them incredibly easy to invent.” Related: China plans its first “Forest City” to fight air pollution The country has urbanized more rapidly than any other country in history. In the last 30 years, more people than America’s entire population have moved to urban areas of China. The country has prioritized development over the environment in many cases, with dangerous air quality found in 90 percent of cities. According to Forbes, as the public has become educated about the pollution, environmental conditions in the country could pose the largest destabilizing force to the Communist Party. Will China’s eco-cities recycle , be powered by renewable energy , produce less carbon emissions , and be built with energy-efficient structures – a few hallmarks we might expect in an eco-city? Williams said, “In the West, eco-cities are supposed to save the world; in China they are simply meant to provide a decent quality of urban environment…China’s eco-cities are simply intended to be much-needed urban improvements and infrastructural development with an eco-prefix.” 80 percent of prefectural-level cities are estimated to have at least one eco-city in the works. One estimate suggests in the near future, more than 50 percent of new urban developments in China will be labeled green, smart, low-carbon, or eco. It remains to be seen whether these eco-cities will genuinely benefit China’s environment – and the people who live in them. Via Forbes Images via Stefano Boeri Architetti

Comments Off on This futuristic table lets you cook, warm, and chill food while you dine

If you thought only the future held a sleek tabletop able to cook, warm, and chill your food, well, welcome to the future. Kram/Weisshaar ‘s Smartslab table features ceramic panels with integrated heating and cooling elements that can be easily be operated using sensor technology. The world’s most innovative dinner party feature may make multi-appliance kitchens a thing of the past. https://www.youtube.com/watch?v=DOnoyrFdFS0 Smartslab material was developed for Iris Ceramic Group using a cutting edge, 6 millimeter-thick ceramic tile called SapienStone . Underneath the slab are induction heating rings for cooking food right on the tabletop, as well as circular warming elements to keep food at a toasty 42.5 degrees Celsius temperature. The table is also equipped with thermoelectric cooling components, meant to keep your glass of water or bottle of bubbly nice and chilled. The designers at Kram/Weisshaar assure users that the table is safe to use and keeps your food and drink at the perfect temperatures. Clemens Weisshaar states, “You need 42.5 degrees Celsius, not more not less. You can put your hand on it and it won’t burn you. With the cooling you need minus five degrees Celsius to keep a glass of water or a bottle of sparkling wine cool.” Related: Brilliant SUNplace table lets you cook with magnified sunlight on a cast iron surface The new technology hints at the possibility of someday incorporating Smartslab design into future kitchens, eliminating the need for expensive and bulky appliances . If all heating and cooling tools could be rolled into one sleek and easy-to-clean unit the modern kitchen could quickly become retro. Further investigation into the innovation’s environmental cost will have to take place before then, but we can still dream. +Kram/Weisshaar Via Treehugger Images via Jürgen Schwope

Solar Impulse 2 begins 4-day nonstop flight across the Atlantic on longest day of the year

Comments Off on Solar Impulse 2 begins 4-day nonstop flight across the Atlantic on longest day of the year

Solar Impulse 2 celebrated the dawn of summer this morning by lifting off from New York’s Kennedy Airport and heading east. Today marks the beginning of the trans-Atlantic leg of the solar-powered aircraft’s round-the-world journey. Bertrand Piccard will pilot the plane for four days and four nights without using a drop of fuel before landing in Spain, the first European stop along the record-setting route. It’s no coincidence that the team chose the longest day of the year for a flight powered entirely by the sun, as the Solar Impulse mission is focused on showing off the awesome potential of clean energy . So, for today, bring on the sun. https://www.youtube.com/watch?v=p0DoOJwvlBk With initiator Piccard at the controls, Solar Impulse 2 took off at 6:30am local time from New York City’s John F. Kennedy International Airport. The pilot will endure a whopping 90 hours of continuous flight time, as the aircraft flies east to its first European destination on the round-the-world trip. Piccard and André Borschberg have taken turns piloting each leg of the journey in the experimental aircraft they developed together, which seats only one person and has a wingspan of just 236 feet. During the day, solar panels on the aircraft soak up the sun’s rays, storing the clean energy in batteries that power the airplane through the night. “André and the team have created more than a revolutionary airplane; they materialized my vision for the future of energy,” said Piccard prior to takeoff this morning. “Lindbergh’s transatlantic flight marked a new area in aviation and contributed to the progress of air transport on a large scale. With Solar Impulse, our aim is to encourage the deployment of clean technologies everywhere. If an airplane can fly day and night without fuel, everybody could use these same efficient solutions in their daily lives.” Solar Impulse 2 departed Abu Dhabi in the United Arab Emirates to begin the global adventure in March 2015. The two pilots have taken turns flying each leg of the journey, all motivated by the desire to illustrate the potential of transportation without fossil fuels. Although the Solar Impulse 2 aircraft is highly experimental and the team has encountered a number of hiccups along the way, such as overheated battery cells in Hawaii which grounded the plane for months, there have been no disastrous failures. So far, the solar-powered aircraft has successfully traveled 18,540 miles of its 25,000 itinerary, which the crew says proves the power of renewable energy . “With this flight over the Atlantic, we are further demonstrating Bertrand’s vision that clean technologies work and can be applied everywhere,” said Borschberg. “We can now make our world more energy efficient. It’s not a question of technology anymore, it’s only a question of mindset: Solar Impulse is like a flying smart grid, and if we can make it work in an airplane, where we can’t cheat, we can make it work on the ground, in our cities, for our homes and for all applications.” As with other legs of the journey, Piccard’s flight is being live broadcasted over Solar Impulse’s website so you can follow along with the adventure. www.solarimpulse.com + Solar Impulse Images via Solar Impulse

Comments Off on Hydro House Concept Utilizes Evaporative Cooling

In hot and dry climates, evaporative cooling is an effective and energy-efficient way to keep things from getting too hot. The Hydro House is a concept home by Rael San Fratello Architects that relies on the cooling effects of evapotranspiration by using ponds, both in and on the home , and through fins that adorn the house. Skylights, portholes and operable windows also provide ample natural daylight and aid in the cooling of the desert home.
