Harvesting static electricity as an energy source

James Gibert has developed an apparatus to generate and measure gas breakdown during contact electrification — the process responsible for static electricity. Their findings, published in Nature Communications, offer insight into the potential and limitations of this type of electricity when harvested as an energy source for a variety of devices, including e-textiles, wearables, and smart packaging.

Cryogenics in zero gravity

As we plan for future interplanetary spaceflight, one major aspect remains untested: refueling in space. That’s because most rocket propellants are cryogenic liquids whose long-term behavior in space is still unknown. Purdue University researchers are collaborating with NASA to study cryogenic liquids in zero gravity, leading to the possibility of propellant depots and refueling spacecraft in orbit.

This trailer powers itself: Purdue and Wabash collaborate on a trailer that recaptures its own energy

The future of electrified transportation isn’t just consumer vehicles. Tractor-trailers carry nearly 72% of the country’s freight, so innovations on that scale have the potential to make huge strides for sustainability worldwide. That’s why Purdue University researchers have teamed up with Wabash, the largest trailer manufacturer in the country, to investigate an experimental trailer that recaptures its own electricity from vibrations, heat, and airflow.

Reducing greenhouse gases at the source by capturing CO2 in a liquid filter

The biggest contributor to climate change is the emission of greenhouse gases like carbon dioxide (CO2) into the atmosphere, especially by heavy industry such as power production and manufacturing. Purdue University researchers have patented a process using liquid filters to remove CO2 at the source, resulting in by-products that can also be recycled and reused.
