In his recent blog post, “Energy Star CFLs superior to incandescent bulbs”, John Dodge highlighted energy savings achieved by replacing conventional bulbs with compact fluorescent lamps (CFLs) in his home. I, too, am a CFL believer. A few months after moving into my apartment in Quincy, MA, I replaced every bulb with a CFL and realized a savings on my electricity bill of roughly 20%. Last year, I even gave CFLs to my family and friends for Christmas!
In a new twist on a 125-year-old technology, General Electric is working on new incandescent materials that will lead to high-efficiency incandescent (HEI) lamps. These new bulbs have potential to be as efficient as CFLs, provide the same light intensity and color quality as conventional bulbs, and feature “instant-on” capability (eliminating the time delay associated with turning on CLFs). In addition, a recent GE press release on HEI technology promises these news bulbs will cost less than CFLs.
There is no word yet on when HEIs might hit the market. So, CFLs remain today’s choice for energy efficient residential illumination. However, we may soon be thanking Mr. Edison once again for commercializing the incandescent light bulb.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
