Just after I blogged Aug. 2 about the huge 2.5 mile Tobin Bridge over the Mystic River/Boston Harbor and connecting the city with to communuties to the north, bits of concrete and metals shards started falling on the Chelsea Yacht Club damaging some boats. No one was hurt and Massachusetts Port Authority officials said the bridge, which carries 76,000 vehicles a day, is safe although they have stepped up inspections. The bridge turns 60 in 2010 and when traffic is bumper to bumper during rush hour, it gets a bit bouncy especially when an 18-wheeler tanker passes you by.
In May, officials announced the aging structure would be painted. In some cases that can cost more than actual bridge construction. Indeed that was the case 50 miles to the north on virtually the same highway (Route 1/95) with the Piscataqua River Bridge which opened in 1972.
The topic of highway and railroad bridges is a hot one with the Aug. 1 collapse of the I35-W Bridge connecting Minneapolis and St. Paul. Today’s quiz: how many gallons of paint will it take to paint the Tobin Bridge (no Googling allowed)?
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
