Researchers Build Innovative, Solar-Powered Toilet

A revolutionary University of Colorado Boulder toilet, fueled by the sun, will assist some of the 2.5 billion people around the world lacking safe and sustainable sanitation.  The technology will be unveiled in India this month. The self-contained, waterless toilet, designed and built using a $777,000 grant from the Bill & Melinda Gates Foundation, has the capability of heating human waste to a high enough temperature to sterilize it and create biochar, a highly porous charcoal, said project principal investigator Karl Linden, professor of environmental engineering. The biochar can be used to both increase crop yields and sequester carbon dioxide, a greenhouse gas. According to the Gates Foundation, the awards recognize researchers who are developing ways to manage human waste that will help improve the health and lives of people around the world. Unsafe methods to capture and treat human waste result in serious health problems and death – food and water tainted with pathogens from fecal matter results in the deaths of roughly 700,000 children each year. Linden’s team is one of 16 around the world funded by the Gates “Reinvent the Toilet Challenge” since 2011.SourceAlso: Have a new design idea? Enter our Create the Future Design Contest.

Flying Robot Would Monitor Environmental Health

With a contract from the U.S. Army, the University of Nevada, Reno is partnering with NevadaNano to develop a robotic flying vehicle that can be used for environmental health and safety monitoring of large areas. The goal is development of a flying robot with integrated chemical sensing, inter-unit communication, and the potential for self-powering. It will be able to "swarm" with other similar units to monitor, collect, and analyze samples while in flight and relay data immediately.

Shape-Changing Wing Flap Reduces Drag and Noise

A milestone for the Adaptive Compliant Trailing Edge (ACTE) project at NASA's Armstrong Flight Research Center occurred with the delivery of two revolutionary experimental flaps designed and built by FlexSys of Ann Arbor, MI, for installation on the Gulfstream G-III Aerodynamics Research Test Bed aircraft. Researchers are replacing the airplane’s 19-foot-long aluminum flaps with advanced, shape-changing assemblies that form continuous bendable surfaces.

Powering Wearable Technology and the Internet of Everything

How are the billions of new wearable technology devices and Internet of Everything sensors going to be powered? We do not want to have billions of toxic Primary batteries in our landfills. These new intelligent devices will need to harvest surrounding ambient energy for life-of-product powering. This White Paper describes how new system architectures, energy harvesting technologies and safe rechargeable solid state batteries can be used to create high-efficiency energy harvesting-based systems.

Advanced Symbolic and Numeric Techniques for Machine Vibration Analysis

The operational reliability of a rotary equipment train is dependent on the vibration of its components. Often, the only evidence of this vibration is gear noise or coupling wear. However, these early indicators might eventually develop into high-amplitude vibration, resulting in gear wear, gear tooth failures, or broken shafts. The torsional response characteristics of rotating and reciprocating equipment should therefore be analyzed and evaluated to ensure system reliability.
