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.
Pongamia has attracted the world's attention as a sustainable substitute for petroleum products and its ability to grow and reclaim marginal lands.
Natural gas production leaks methane along its entire supply chain - from drilling to storing, processing to distributing.
Even a small farmer could join a co-op and get in on this trend. These co-ops are growing and are being promoted by organizations interested in furthering the cause of renewable energy.
Ethanol production must move away from the exclusive use of corn, or any food crops, as a feedstock. Our technology will allow for biomass diversification, and the use of the most abundant biomolecule on Earth: cellulose.
Biofuels made from the leftovers of harvested corn plants are worse than gasoline for global warming in the short term, a study shows, challenging the Obama administration's conclusions that they are a much cleaner oil alternative and will help combat climate change. A $500,000 study paid for by the federal government and published Sunday in the peer-reviewed journal Nature Climate Change concludes that biofuels made with corn residue release 7% more greenhouse gases in the early years compared with conventional gasoline. Biofuels are better in the long run, but the study says they won't meet a standard set in a 2007 energy law to qualify as renewable fuel. The conclusions deal a blow to what are known as cellulosic biofuels, which have received more than a billion dollars in federal support but have struggled to meet volume targets mandated by law. About half of the initial market in cellulosics is expected to be derived from corn residue. The biofuel industry and administration officials called the research flawed. They said that it was too simplistic in its analysis of carbon loss from soil, which can vary over a single field, and that it vastly overestimated how much residue farmers would remove once the market gets underway.
At Algenol, algae is combined with carbon dioxide, salt water and sunlight in Algenol's proprietary photobioreactor system to produce thousands of gallons of fuel per acre.
Waste heat to electricity uses less fuel to produce a given energy output, and avoids transmission and distribution losses that occur when electricity travels over power lines. It also decreases the impact of outages when the power grid goes down.
The process relies on heat and pressure to break down the long hydrogen, carbon and oxygen polymers that make up plastics. From there, these elements are recombined into the shorter hydrocarbon chains that can be effectively burned as diesel or gasoline.
This report serves as an overview of gasification technologies processing municipal solid waste (MSW) that includes non-recycled plastic.
As CHP systems can tap into a wide array of fuels to operate including coal, biomass and natural gas, there are few restrictions on where they can be installed.
