A reflective surface reduces smog by reflecting heat back into the atmosphere. Not only is the smog reduced, but more importantly, energy costs are lowered in big cities.
A revolutionary >5kWe cogen pellet boiler prototype system, designed and manufactured by ÖkoFEN, with Qnergy's Stirling engine inside, was introduced to the market. The biomass boiler is still under development and the first beta installations are expected before the end of the year to serve large residential and small to medium application requirements.
Amyris' innovative bioscience technology directly converts plant sugars into hydrocarbon molecules to create the renewable fuel, and the technology enables the operations of the Amyris-Total partnership to deliver the fuel from "field to wing."
From Science 2.0: Harvesting sunlight is old technology for plants but it's a level of efficiency in solar energy we would love to be within a billion years of - artificial photosynthesis is needed if we want to go beyond the energy density of things like combustion engines. Solar energy, using electricity from photovoltaic cells to yield hydrogen that can be later used in fuel cells, would be terrific but has technological obstacles. Now scientists have created a system that uses bacteria to convert solar energy into a liquid fuel. Their work integrates an "artificial leaf," which uses a catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert carbon dioxide plus hydrogen into the liquid fuel isopropanol. Pamela Silver, the Elliott T. and Onie H. Adams Professor of Biochemistry and Systems Biology at HMS and an author of the paper, calls the system a bionic leaf, a nod to the artificial leaf invented by the paper's senior author, Daniel Nocera, the Patterson Rockwood Professor of Energy at Harvard University.
Will China Be The First To Mine Lunar Energy?
In the United States, more than half of the energy we burn each year gets lost as heat instead of being put to use with most of the energy going out the exhaust pipe of a car or out the smokestack of a power plant.
The roads constructed using this technology are more durable and economical than the conventional bitumen roads.
Waste Heat to Power (WHP) creates electricity by heating a fluid at high pressure, then expanding the fluid through a turbine to power an electric generator.
This white paper takes a novel, nationwide approach to estimating an overall impact on emissions and cost. It sheds light on the role that energy efficiency can play as a compliance mechanism.
Essentially, we're giving the solar panel a brain; the patented HEMOS chipset can be fitted in a typical junction of any solar panel. With it you can communicate directly with the panel and execute commands at the module level.
The largest military contractor in the United States is developing a nuclear fusion reactor that is small enough to fit on the back of a truck but has the ability to produce the energy required to power a warship. Lockheed Martin said in a statement released on Wednesday this week that its secretive Skunk Works division — the unit responsible for the U-2 spy plane and F-117 stealth jet — has already applied for several patents related to the high-tech reactor it has in the works, and expects it to be deployed during the next decade if interested industry and government partners sign on to help starting soon. “Our compact fusion concept combines several alternative magnetic confinement approaches, taking the best parts of each, and offers a 90 percent size reduction over previous concepts,” Tom McGuire, the compact fusion lead for the Skunk Works’ Revolutionary Technology Programs, said in a statement. “The smaller size will allow us to design, build and test the CFR in less than a year.”
For people who use coal or oil for heating, switching to biomass will certainly reduce carbon emissions as long as there is a program in place for sustainable management of the resource.
As more species and cultivars are proposed to help meet the substantial renewable energy needs of our nation, more risk assessments will be necessary to identify the truly green renewable alternatives to petroleum-based energy sources.
Since biogas can be used as fuel to generate electricity, the city wanted a means to reliably collect biogas from the BVF® reactor to recover the energy while also controlling odors and reducing greenhouse gas emissions.
It's important to decrease the environmental impact by reducing the size of the packaging, switching to renewable raw materials, reusing materials, and finally, recycling materials for later use.
