This week on Txchnologist, we watched the world’s first 3-D printed car hit the road after being made in a mere 44 hours. The vehicle, called Strati, was sent on a test drive last Saturday after being quickly printed and assembled by a Local Motors team days before. The company plans to offer 3-D printed vehicles for sale in the coming months, paving the way for innovation in automotive design and opening new doors for modern manufacturing.
The creators of an MIT project called Local Warming are pioneering a heating system that uses motion sensing to direct infrared energy beams at occupants of a space, heating them directly while the remaining space stays cold. With current space heating accounting for 37 percent of the total power consumed by U.S. buildings in 2010, funding programs that rethink how to keep people comfortable could spark a radical shift in greater building energy efficiency nationwide.
Smog-producing low-level ozone concentrations are rising globally and bringing with them heightened public health and ecological threats. Scientists studying the environmental dangers of ozone offer a simple solution—plant more trees. Their models have shown that the reforestation of regions directly abutting urban areas provides an effective tool for abating ground-level ozone pollution, and could complement technology-based controls.
Now we’re bringing you the news and trends we’ve been following this week in the world of science, technology and innovation.
