Water Treatment Technologies Inspire Healthy Beverages

Purification techniques for astronaut drinking water find use in probiotic drinks.At NASA’s Johnson Space Center in the mid-1990s, Mike Johnson assisted the scientists who were developing technology to convert urine into drinking water. The research conducted by the Advanced Water Recovery Systems Development team has proven vital to space exploration. Thanks in part to their work, astronauts in low Earth orbit make the most of their resources, and those who will take part in future missions — like a trip to an asteroid or Mars — can count on having drinkable water for the journey.

Sustainable Technologies Category Winner (Winner of an HP Workstation)

Aquaback Water Purification SystemBill Zebuhr, Scott Newquist, David Dussault, E. Andrew Condon, Steven Sahagian, Nicholas Wong, Michael Easton, William Burie, Charles Blanchard, and Nicole Sandoval, Aquaback Technologies, Tewksbury, MAA highly efficient, low-cost, lowmaintenance, compact, modular vapor compression distiller is designed to be the water processing module in a wide variety of water processing systems to clean incoming water or reclaim waste water. The systems will enable recycling of most water for any use, including potable water, at a lower overall cost than any other technology or combinations of technologies, addressing water supply and disposal problems worldwide. Distillation provides the highest-purity water in a single operation, but until now, distillers have been too expensive to make or operate to be practical. Aquaback has optimized every aspect of distillation using the known vapor compression method to recycle over 99% of the heat of vaporization using a mass-manufactured, self-cleaning design.

Can Cobalt-Graphene Beat Out Platinum As Catalyst in Hydrogen Fuel Cells?

Platinum works well as a catalyst in hydrogen fuel cells, but it is expensive and degrades over time. Brown University chemist Shouheng Sun and his students have developed a new material — a graphene sheet covered by cobalt and cobalt-oxide nanoparticles — that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable.

Promoting Virtual Power Plants for Efficient Renewable Energy Production

Researchers from the School of Electronics and Computer Science (ECS) at the University of Southampton have devised a novel method for forming virtual power plants (VPPs) to provide renewable energy production in the UK. Small and distributed energy resources (DERs), such as wind farms and solar panels, have been appearing in greater numbers in the electricity supply network (Grid).

Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries

Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.
