To slim down the end shield, Siemens developed a special optimization algorithm and integrated it into the Siemens CAE-Program NX Nastran.
Attempting the First Round-The-World Solar Flight to inspire innovation and encourage the use of clean technologies, the solar powered airplane of Bertrand Piccard and André Borschberg successfully landed at the Chongqing Jiangbei International Airport this week.
A Swiss team planning to complete the first round-the-world solar flight next year unveiled a new version of their unique ‘Solar Impulse’ aircraft, which they say could remain in the air indefinitely ...
Should the green building certification system give its highest rating to uses that are laughably inappropriate ...
I saw the first generation of this plane when it flew across the United States last year. Needless to say, it was incredible. It had the wing span of a 747 with a very tiny cockpit for the pilot. This cockpit was not appropriate for the length of flight required to circumnavigate the globe, the team’s.. ...
BATTERIES - Electrovaya delivers next-gen prototype battery packs to Dongfeng Motors; 20% greater capacity
Electrovaya Inc. has delivered its next generation of prototype battery packs to Dongfeng Motors (DFM) in China. DFM, a leading Chinese automaker, is embarked on an electric vehicle program which includes two electric vehicle platforms. The Electrovaya battery design enables the same Electrovaya battery to fit both the 2-door and 4-door electric vehicle platforms from DFM.Due to ongoing improvements in the cell manufacturing process, this battery ...
BATTERIES - Freescale introduces intelligent battery sensor combining MCU and CAN with flexible three-channel analog front end
Freescale Semiconductor announced the availability of the industry’s first general market AEC-Q100 qualified intelligent battery sensor to combine three measurement channels, a 16/32-bit MCU, and a CAN protocol module in a single package. Designed to support both conventional and emerging battery chemistries for automotive and industrial applications, the MM9Z1J638 battery sensor measures key battery parameters for monitoring state of health (SOH ...
BATTERIES - New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also
Schematic of mesoporous silicon Image: Donghai Wang/Penn State. Click to enlarge.Researchers at Penn State have devised a new process for the bottom-up synthesis of mesoporous crystalline silicon materials with high surface area and tunable primary particle/pore size via a self-templating pore formation process.The nanosized crystalline primary particles and high surface areas enable an increased rate of photocatalytic hydrogen production from wa ...
After bike lanes were installed in Minneapolis, there were more cars per unit of road space, but still not enough to meet the threshold for congestion.Gretchen Johnson and Aaron Johnson have posted a nice debunking of typical “war on cars” rhetoric over at fivethirtyeight.Johnson and Johnson gathered before-and-after traffic data from 45 miles of streets where Minneapolis installed bike lanes. They also looked at how Brooklyn’s Prospect Park West ...
Bykes - Do bike lanes slow car traffic? Not if you put them in the right place, according to FiveThirtyEight
The stats site crunches the numbers and the results should make cyclists and planners happy. Rob Ford is another story ...
