Building a Safer Lithium-Ion Battery
Lithium-ion batteries continue to be the technology of choice for small electronics but, as illustrated here, their continued evolution and the introduction of new large format applications require a closer look at the technology inside the battery.
Direct Methanol Fuel Cells
The direct methanol fuel cell or DMFC is emerging as a future winner in many of the applications that fuel cells can satisfy. DMFC is an important subset of the proton exchange membrane (PEM) fuel cell technology.
Ultracapacitors Double Life of Wave Measurement Buoys
By working together with a primary battery, the ultracapacitors have helped to at least double the lifetime, which means that battery life no longer determines the service interval for the buoy.
Benefits of 24/7 Battery Equalization
The equalizer captures energy from batteries with "above average voltage" and dumps that energy into the ones with "below average voltage". When the overachievers try to excel in voltage, their excess energy is used to bring the underachievers up to par.
Can Electricity Save Energy
With the increasing conversion efficiency of electricity in generation, the increasing share of renewable electricity, the high efficiency at the point of use and the potential for system level efficiencies, there is a lot of supporting evidence for a claim that electricity can save energy.
China's Attempt to Balance the Environment and a Rapidly Growing Economy
China may be positioning to change its global image from environmental disasters to an environmental leader, as it was recently recognized as the world leading investor in renewable energy.
Is America ready for Wind Hydrogen?
While flow batteries and other devices can be used to compensate for wind's intermittent output, it's difficult to match the investor and political enthusiasm for hydrogen.
Micro Thermoelectric Generator Targets ZigBee
The main purpose for developing the Thermo Life is to provide energy harvesting for low-power applications where other technologies would prove inadequate or not possible.
More than 125 MW of "Huerta Solar" PV plants
A "Huerta Solar" is the Spanish term for solar farm and is a grid-connected solar power plant based on several subsystems, each with their own investor.
Can Nuclear Power Deliver?
Too often the energy debate is fragmented, and focuses on advantages of a particular technology and disadvantages of its alternatives. If we exclude the nuclear option portfolio, a plan is needed how to do without it.
Different Types of Fuel Cells
There are several other fuel cells in the research labs and in development today. With this wide array of technologies and the myriad of applications, fuel cells are poised to revolutionize the way we think about and use energy today and in the future.
Making Green, Inexpensive Hydrogen Fuel -Renewably.
Make hydrogen from sea water renewably. This avoids depletion of limited supplies of fossil fuels. It produces no harmful side products. No carbon is released. The investment is recovered and a large return on investment is realized by selling the hydrogen. Everyone wins.
Grid Friendly™ Appliances
What can home appliances do to help ensure the reliability of the electricity grid? A lot—if they employ smart control technology.
Solar Energy Potential At Different Latitudes
I was surprised to see that, in Germany, where they receive a fewer amount of energy with respect to other countries, by the end of 2003 had clearly invested more in solar panels than many other countries which get more solar energy than them.
Hydrogen Solar's Tandem Cell, Chosen For Britain's Science Museum Nanotechnology Exhibition
The Tandem Cell converts the energy of sunlight directly into hydrogen gas by splitting water into it's constituent elements, Hydrogen and Oxygen.

Featured Product
HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
