Solar Power for Small Sensors

Wireless sensors are becoming more pervasive as we move toward the “Internet of Things” that futurists have been telling us is on the horizon. But for these sensors to work, they have to have power. In some cases, the sensors can piggyback on items that are already hooked up to the grid (like refrigerators). In others, though, the sensors either need battery power or some other form of energy, and that has traditionally mean that the sensors themselves have to be large enough to accommodate a power source. Those size considerations, in turn, limit design possibilities. Continue reading

Adaptive, Moving Sculptures Respond to Environment

Malta architect William Bondin has come up with a prototype sculpture that could turn public art into malleable, moving “organisms” that respond to their environment as they change shape and position. The scaffolding-like structures would use solar energy to power light and moisture sensors that would help guide the structures as they changed position — a concept that is both delightful and unnerving.

Driverless Cars Could Save Thousands of Lives

We’re still a few years away from seeing fully autonomous cars roaming freely on U.S. highways (although Nevada, Florida and California may be seeing them a little ahead of the rest of us), but once the technology is more common, we could see a significant reduction in highway fatalities and lost productivity.

Smart Rifle Accurate Up to 1,000 Yards

I have a confession to make: I’m a lousy shot. Hand me any type of gun to fire at almost any type of target, and I’m 90% certain I’ll miss.

A company in Texas has come up with a high-tech weapon that takes the human-error element out of marksmanship almost completely. Tracking Point, based in Austin, has developed a $25,000 gun (in the company’s nomenclature, a precision-guided firearm) that allows even novice shooters to hit targets up to 1,000 yds. away with nearly 100% accuracy. According to this article on CNET, one of the company’s engineers was even able to nail a moving stinkbug at 98 yards. Continue reading
