  • Designers looking to save power and size are turning to advanced technologies, and motors are no exception. With piezoelectric technology at the heart, a new type of motor is improving small-scale motion systems in a big way. Electronic access control enhances security, convenience, safety, and flexibility in a wide range of applications from building automation to automobiles. Today, system designers are adding "smallest size" to the requirements list for the electronic actuators at the core of access control systems.

harebrained renewables scavenging harvesting

  • In the 21st century we have seen numerous ways to create alternative energies. Some are much more popular than others (Eco Football), but throughout the thought process there seems to be a unique pattern in the sources of renewable energy, most of which are inspired by mother nature. Piezoelectric is a science that produces energy as an object is bent, deformed, or stressed. According to Groovy Green “Scientists at the CEA/Leti-Minatec in Grenoble are looking at this technology as a way to harness the vibrations caused by falling raindrops. According to the article, the system works with raindrops ranging in diameter from 1 to 5 mm, and simulations show that it’s possible to recover up to 12 milliwatts from one of the larger ‘downpour’ drops

    Another apparent harebrained idea. Wouldn't it be more economic to capture rain and run it through a hydro turbine?

    by placing piezoelectric crystals under the asphalt that convert vibration into electricity, Israeli engineers hope to harvest energy from passing vehicles.

  • It is important to note is that there is a lot more out there than what we see in the everyday. In fact, you will see here that there are dozens of proven methods of harnessing the power of nature in sustainable ways. Some of the more interesting examples that may be applicable as a medium for public art installations are the translucent thin films which can be flexible and offer interesting hues and textures, piezoelectric generators that capture vibration energy, and concentrated photovoltaics, which allow for interesting play with light. But the possibilities are endless and new designs are coming into the market all the time that can be artistically integrated into beautiful sustainable infrastructure.
