New Lab Delves into Plants for Fuels
A new integrated facility designed to give scientists unprecedented insights into the chemical and biological reactions which can transform renewable plant and waste materials into useful sources of energy was dedicated yesterday at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL).
Called the Biomass Surface Characterization Laboratory (BSCL), the $2.85 million facility features an array of electron and optical microscopes, and other advanced res
Almost Only Counts in Horseshoes – and Computer Chips
Flawed Hardware Can Function Well in Many Applications, USC Researchers Find
Computer chip manufacturers traditionally have had a single, simple standard for their product: perfection. But a USC engineer who has spent his career devising ways to have chips test themselves has found that less than perfect is sometimes good enough — possibly good enough to save billions of dollars. “Chips with any flaws at all have always been discarded,” said Melvin A. Breuer, a professor in the
Bringing unique remote sensing and actuation technology to market
British company Instrumentel has developed a revolutionary communications technology that enables two-way command and control for battery-less remote sensing and actuation.
The company originated from the University of Leeds, where ground-breaking research by Dr Greg Horler of the Department of Electronic and Electrical Engineering has produced an inductively coupled wireless telemetry system based on miniaturised electronics that can both sense and actuate.
It is bel
Avenir Energie’s Geopack pumps up the energy
Loops of small diameter polyethylene-coated copper tube are buried between 50cm and 60cm below the surface of the garden of the house to form a captor through which refrigerant fluid is pumped, typically R407c blend. A scroll compressor and a stainless steel plate heat exchanger within the generator unit complete the circuit to transfer the energy captured from the soil into the house.
The energy taken from the soil is quickly and continually replaced by sunlight, wind and rainfall
Working for a safer and more reliable electrical supply
Computer simulations will improve understanding of faults and power surges
Scientists at Cardiff University, UK have been called in to help improve the already high levels of safety and reliability on the UK’s electrical transmission system. A team of experts in Cardiff School of Engineering will run sophisticated computer simulations, laboratory experiments and field tests on the National Grid electricity network to develop a better understanding of what happens when faults a
Teams build robots that walk like humans
’Toddler’ to be demonstrated at AAAS meeting Feb. 17
Three independent research teams, including one from MIT, have built walking robots that mimic humans in terms of their gait, energy-efficiency, and control. The MIT robot also demonstrates a new learning system that allows the robot to continually adapt to the terrain as it walks. The work, to be described in the Feb. 18 issue of the journal Science, could change the way humanoid robots are designed and controlled and
