Comments Off on Efficient "ice battery" provides 24/7 cooling for your home
The eco-friendly and cost-effective “ice battery” method of residential indoor climate control has been around for more than a decade, but one company still believes it is the answer to inefficient air conditioning units. California-based Ice Energy is the company that makes Ice Bears for both residential and commercial installations. The cooling units promise to save home and building owners a ton of money, while providing reliable cool air with a smaller environmental impact than traditional air conditioning. The system is based on a simple concept—ice is cold and can make air cold, too—but the sophisticated system is both smart and flexible to respond to the demands of a modern world. The company has lofty claims for its ice-based cooling units, saying the Ice Bear system “reduces peak cooling electricity by 95 percent for up to 6 hours a day” resulting in energy savings up to 40 percent overall. The efficient unit essentially makes ice, a low energy task, and then uses it to cool your home’s air. Ice Bear can reportedly get four hours of cool air from its ice with the compressor shut off, which means it uses a lot less energy than a traditional air conditioner.

It’s a smart system, too, designed with remote monitoring and control capabilities, as well as a host of reporting features that allow homeowners to see graphical representations of their energy usage.

Comments Off on BeCool HVAC system generates clean energy while keeping your house cool
Most air conditioning units are energy hogs that can send an electric bill sky high, often leading people to limit their use. A new device called BeCool cools (or heats) the air while charging up a fuel cell at the same time , could transform the whole approach to indoor climate control by generating electricity rather than just sucking it up. The invention comes from Be Power Tech , a startup based in Florida, where air conditioning is not just a luxury, but also a lifesaver. https://vimeo.com/165074817 Instead of plugging into the grid for its power source, Be Power Tech’s BeCool commercial HVAC unit runs on natural gas . Where the individual unit is considered, the result is a more energy efficient air conditioning system. If more people relied on natural gas-based air conditioners, some of the strain on the power grid would be alleviated during peak times of usage, such as during a heat wave or simply at that point in mid-afternoon when the day’s heat reaches its apex. Related: Infographic shows surprising trends in summer energy usage across the United States The BeCool system is a roof-mounted unit that directly replaces standard 10-ton air conditioning systems, and the company will begin field trials on commercial units in 2017, expecting to hit the market the following year. The system relies on evaporative cooling technology developed at National Renewable Energy Laboratory (NREL) and licensed by the Florida company exclusively. The system promises to reduce energy costs by 67 percent or more, with a 70 percent reduction in peak time usage. BeCool, which is also capable of functioning as a heating unit, is also an environmentally friendly system. Its inventors claim installing one of their HVAC units is the equivalent of removing five cars from the road, due to the reduction in emissions gained both by fueling the unit with natural gas and by its clean energy generation.

Comments Off on New 3D solar cells capture sunlight from every angle
Georgia Tech scientists developed three-dimensional solar cells which just hitched a ride to space this week on a SpaceX rocket. At the International Space Station , the solar cells will be tested to see how well they function and how they respond to space conditions. The solar cells have been designed to capture the sun’s rays from every angle, which could enable spacecraft to gain more power from a limited surface area. The experimental module blasted into space includes four different types of solar cells. One type is a “traditional planar” solar cell, and a second is a planar cell based on a formulation of low-cost materials: copper-zinc-tin-sulfide (CZTS). These materials cost about ” a thousand times less than the rare-earth elements ” like selenium and indium used in some solar cells. There are also two types of 3-D solar cells: one “based on CZTS” and the other “based on conventional cadmium telluride.” There are 18 solar cells total, and they will be tested in space for six months. Related: 2,500 orbiting solar “flying carpets” could power the planet 3-D solar cells could forever alter the way spacecrafts receive power. The Georgia Tech solar cells are described as miniature “towers” coated with a “photo-absorber.” Instead of requiring the sun to be right above them to work, the innovative 3-D solar cells can capture sunlight over longer periods of time. Georgia Tech Research Institute principal research engineer Jud Ready said in a press release , “We want to see both the light-trapping performance of our 3-D solar cells and how they are going to respond to the harshness of space.” After six months, the solar cells will return to Earth so scientists can study how they held up in space. According to Ready, “If it can survive in space, which is the harshest of environments from the standpoint of wide temperature swings, radiation, and numerous other factors, then we can be confident it will work well down on Earth.” Via Phys.org Images via Gary Meek, Georgia Tech

Comments Off on Atkins’ H2 low carbon building is an “ecological sandwich” in China
The newly opened TEDA H2 Building in China is the world-first low-carbon building that has been accredited with four green building certificates: the US LEED (Gold), Chinese 3-Star, Japanese CASBEE (S Class) and the British BREEAM (Very Good). Designed by Atkins , the building incorporates a variety of green building initiatives, including simple techniques such as rainwater harvesting to relatively complex photovoltaic systems for solar energy.
