Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow due to low porosity and high "dead space" that come from starting with a solid material and trying to impart porosity. This work uses an alternative approach, where linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60-70%) and so have much higher ionic flow.
Standards-based solutions were instrumental in the exponential growth of the Internet. For the Smart City, public electrical infrastructure ecosystem to expand, development, application and worker training of interoperability standards is an important strategic foundation from which to grow. This convergence of intelligent transportation systems with the Smart Grid, is allowing the Smart City concept to gain hold in many areas of the US and around the world.
As the technology of renewables advances, and as their track records continue to show stable returns, pension funds will continue to increase their investment in renewables, either through direct investment, infrastructure funds or private equity funds.
The S.P.M. Mill operators initially tried using Oscillator and Vortex technology flow meters. They found that these flow technologies contain moving parts or orifices and were unable to measure flows accurately at the low flow rate demanded by this digester application.
On average, a California solar system will pay for itself within five to 10 years, depending on the size of the system. However, if the system is leased and homeowners put little down upfront, the solar system will begin paying for itself on day one, creating instant savings.
The iSolar Exchange online marketplace is designed to create a secure site that connects the entire supply, manufacture, and delivery channels for solar and renewable energy products and services - worldwide. That's all we do - that's all we focus on.
In current technology about 30% of the light is reflected back into space. We have created a 3-dimentional structure in the silicon that virtually eliminates reflection by causing the light to bounce around within the structure until it is fully absorbed.
Fuel cells can help resolve many issues facing ports. By deploying this clean and modern technology, ports can reduce pollution and increase operational efficiency. Fuel cells generate electricity using electro-chemical reactions, not combustion, so there are no polluting emissions, only water and heat as by-products.
Algae converts at a very high efficiency into biocrude, as it has lots of caloric value and happens to have the same molecular structure as petroleum. So out of all the whole biomass sources, algae is probably the most efficiently converted to biocrude.
While the addition of each Plug-in Hybrid Electric Vehicle (PHEV) to the street is a victory for the environment, their widespread adoption will present another potential challenge to the power distribution system, particularly in urban networks.
Federal and state R&D credits provide a dollar-for-dollar offset against tax liability up to an average of approximately 15 percent of qualified spending, i.e., taxable wages, supply expenses, and a percentage of contract research expenses related to research that goes into developing new and improved products and processes.
Recent developments in communications, computational capability, and data availability all lend themselves to a high level of intelligence both on the battlefield and within the utility. The proposed benefits of the "smart grid" align well with recent developments in data integration, mining, and fusion.
We are asking for the support of the PV industry in our ongoing efforts to aggressively fight the theft and infringement of IP, and to help ensure it does not continue to proliferate. Companies should consult their own legal counsel if they have any questions about the materials they have in use and the potential implications of the production and sale of downstream products which incorporate "infringing" materials.
Profitable and safe operation of a biogas plant involves the interaction of many factors. Providing 360°screening, technical due diligence ensures clarity regarding safety and cost-effectiveness throughout all phases of the project.
Here are 16 of the potential failures or damages that can occur on a solar farm and how they could impact operations if not addressed in a timely manner.

EDF Renewables offers the same innovative solutions that maximize the performance of our own 5.2 GW of installed projects. Because we're not an equipment manufacturer, our recommendations are transparent and data-driven. We cover the entire project lifecycle: from pre-commissioning support, through warranty and post warranty operation, to late stage and decommissioning.
