A new device transforms almost any bicycle into an electric-hybrid vehicle using an app on a smartphone. The device, called the Copenhagen Wheel, is is equipped with wireless connectivity to track travel and installed as part of a rear hub of a bike wheel. Packed with a proprietary computer, batteries, and sensors that monitor how hard a rider is pedaling, it activates an onboard motor whenever support is needed.
API Delevan now offers three SMD power inductors with the highest reliability rating currently available. The MILP1812, MIL4922 and MIL8532 meet all military QPL requirements, and the ruggedized molded and leaded construction is proven against MIL-STD-202 mechanical vibration, moisture resistance, and DWV testing.
A new maritime propulsion technology called the RudderPod, which steers independently of the main propulsion unit, could save up to half a million euros in fuel costs, according to the TRIPOD research project collaborators in Europe who plan to retrofit the new system to a ship for testing. The project aims to improve propeller efficiency as well by integrating RudderPod with new types of propellers.
Semiconductor Research Corporation (SRC) has launched a new research program on hybrid bio-semiconductor systems that they hope will provide insights and opportunities for future information and communication technologies. The Semiconductor Synthetic Biology (SSB) program will initially fund research at six universities.
Amy Prieto, a chemist at Colorado State Univ. leads a start-up company with the goal of developing a lithium-ion battery that should be safer, cheaper, faster-charging, and more environmentally friendly than conventional batteries now on the market. The key to the technology is copper foam which is easy to manufacture and has high power density.
Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of scientists has quantified this effect for the first time using high-resolution 3D movies recorded using x-ray tomography at the Swiss Light Source.
The SpectraLight QC is a visual color assessment lightbooth that can meet practically any specification. This holistic solution starts with state of the art light sources, and includes a data-driven back-end that carefully monitors the performance and condition of lamps, as well as a system to educate and certify operators.
B&K Precision has introduced three new base models to its XLN Series of programmable DC power supplies. Expanding on the success of the XLN Series, the new models, XLN15010, XLN30052 and XLN60026 offer an even greater range in output voltage, up to 150V, 300 V and 600 V, respectively.
Speaking at the American Chemical Society’s meeting in Indianapolis this week, electric vehicle pioneer John E. Waters said that relatively recent advances in engineering and use of lithium-ion batteries are producing electric vehicles (EVs) capable of leaving traditional internal combustion engine race cars in the dust. Part of the shift is the elevated storage-to-torque efficiency of electric motor.
B&K Precision has expanded its DC system power supply offerings with the introduction of the model 9115 multi-range programmable DC power source. The 9115 can deliver up to 1200 W in multiple combinations of voltage up to 80 V and current up to 60 A in a 1U form factor.
On Thursday, electric car maker Tesla Motors Inc. said that by the end of next month it will triple the number of charging stations it runs from the current eight. The number will go to around 100 in the coming year, putting stations within reach of almost the entire populations of both U.S. and Canada. The expanded "supercharger" network will allow owners of Tesla's $70,000 Model S sedans to travel from Los Angeles to New York.
After China reported quarterly economic growth of 7.7% this week, global markets reacted by falling, wiping out billions of dollars in stock. The reason? Growth came in under the 8% expected by forecasters. The plunge highlighted complaints about the possible inaccuracy of Beijing's official data and the intense, possibly excessive importance traders attach to a handful of Chinese economic indicators.
Recent research shows that a newly discovered class of materials, called layered oxide heterostructures, could have optimal electrical characteristics. A research team at the Vienna University of Technology, together with colleagues from the United States and Germany, has now shown that these heterostructures can be used to create a new kind of extremely efficient ultra-thin solar cells.
For years, scientists have studied the potential benefits of a new branch of solar energy technology that relies on incredibly small nanosized antenna arrays that are theoretically capable of harvesting more than 70% of the sun’s electromagnetic radiation and simultaneously converting it into usable electric power. A new fabrication technique developed by University of Connecticut engineering professor Brian Willis could provide the breakthrough for this technology.
It may be possible soon to charge cell phones, change the tint on windows, or power small toys with peel-and-stick versions of solar cells. A partnership between Stanford University and the National Renewable Energy Laboratory aims to produce water-assisted transfer printing technologies that support thin-film solar cell production.
Engineers in Israel have created a radically new design for a concentrator solar cell that, when irradiated from the side, generates solar conversion efficiencies which rival, and may eventually surpass, the most efficient photovoltaics. The design, the developers say, can exceed 40% conversion efficiency at intensities of 10,000 suns.
The nearly released integrated devices iC-HD2, iC-HD7 and iC-HE from manufacturer iC-Haus are line drivers for 5 V and 24 V industrial encoder/sensor applications. The output drivers are designed for cable impedances in the range of 30 to 140 ohms. The devices feature a unique integrated wave impedance adaption.
Researchers in Germany and Israel have developed a method to measure photocurrents of a single functionalized photosynthetic protein system. The proteins represent light-driven, highly efficient single-molecule electron pumps that can act as current generators in nanoscale electrical circuits. According to the findings these proteins can be integrated and selectively addressed in artificial photovoltaic device architectures while retaining their biomolecular functional properties.
As data centers continue to come under scrutiny for the amount of energy they use, researchers at University of Toronto Scarborough have a suggestion: turn the air conditioning down. Their latest research suggests that turning up the temperature could save energy with little or no increased risk of equipment failure.
The competition in the photovoltaics (PV) market is fierce. When it comes to price, Asian manufacturers are frequently ahead of the competition. Now, researchers in Germany are designing new coating processes and thin layer systems that may help reduce the price of solar cells significantly, and change the balance of power in PV.
According to data from a 2008 Business R&D and Innovation Survey by the National Science Foundation, businesses perform the lion's share of their R&D activity in just a small number of geographic areas, particularly the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area.
Massachusetts Institute of Technology researchers have developed a new technique for magnetically separating oil and water that could be used to clean up oil spills. They believe that, with their technique, the oil could be recovered for use, offsetting much of the cleanup cost.
Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell uses mechanical energy more efficiently than systems using separate generators and batteries.
After making a sheet of “paper” from the world’s thinnest material, graphene, Rensselaer Polytechnic Institute scientists zapped it with a laser.
