Proof-of-Concept Piezoelectric Generators Used to Recover Energy from Wind
City College of New York researchers, led by professor Yiannis Andreopoulos, are studying how to incorporate piezoelectric electricity generators into cars and planes, so they can convert the kinetic energy of motion into electricity.
Solar Heat Powered Machine Turns CO2 Back Into Fuel
This is the simple description, of course - the machine, made of a metal cylinder, is called the CR5 (Counter Rotating Ring Receiver Reactor Recuperator) is working on the principle that heat triggers a thermo-chemical reaction in an iron-rich composite material.
Researchers Use Wind Turbine Technique to Build Efficient Wave Powered Generators
Mankind has been adopting the working principles of natural phenomenons and animals since ages. Now, when it's time to learn from fish to develop wave-powered generators, it's also time to learn what others have learned from birds - and use them in the seas, to gather energy which they would later turn into electricity.
Solid-State Rechargeable Lithium-Air Battery Reduces Risk of Explosion
Binod Kumar, a research engineer and leader of UDRI's electrochemical power group said that the university is looking for partners that could license the â€Ã…“breakthrough†technology for manufacturing the batteries.
Interesting and Easy to Build Solar "Sandwich" Makes Efficient Use of Space
I have just received a comment on one of my articles this afternoon from a certain mr. Ryszard Dzikowski, who presents his innovation I call "solar sandwich", consisting of two Gratzel organic cells, faced one another, and covered by reflective layers on the sides, except for one, which is used to feed the aggregate with light.
Imperfecting Carbon Nanotubes Makes Them Very Good Fast-Charging Batteries
Prabhakar Bandaru, a professor in the UCSD Department of Mechanical and Aerospace Engineering, along with graduate student Mark Hoefer, have discovered that artificially introducing defects in carbon nanotubes would increase their energy storage capacity.
Widetronix and Ithaca Making Progress in Betavoltaic Battery Research
Nuclear power has been discarded for decades since the tragic accidents from the 80's that led to numerous environmental damages in Ukraine and other parts of the world. Still, nowadays there is a trend of reviving nuclear power, to make it 100% safe and to convince people it's worth investing in it, as an alternative to coal or petrol.
New Polymer Synthesis Cuts Plastic Solar Cell Production Time by 50%
Their discovery drastically reduces the reaction time (99% faster). In the past, the reaction that took place in 48 hours, now only lasts 30 minutes and increases the average molecular weight of the polymer by a factor of more than three.
New MIT Thermoelectric Device Pushes Efficiency to Its Theoretical Limit
The Carnot Limit, calculated in the 19th century, demonstrates and sets the maximum efficiency that any device can achieve in converting heat into work. Theoretically and practically, you can't go over that limit. So, the devices constructed up to now only get a tenth of Carnot's limit.
Injecting CO2 Instead of Water in Geothermal Wells Could Triple-Serve the Environment
When we hear about carbon dioxide, it's like hearing of a serial killer. LBNL (Lawrence Berkeley National Laboratory), and a CA-based company Symyx Technologies, instead, aided by several U.S. universities, have changed the image of this greenhouse gas a bit by putting it into a green job: geothermal energy harvesting.
