  • Electric airplanes developed by a Colorado startup take aim at global pilot shortage

    The aviation world is changing and companies like Bye Aerospace are leading the way toward a new industry with the development of an all-electric airplane. At the same time, the number of pilots in the United States is dwindling due to the expensive cost of pilot training, which comes from the high fuel costs associated with the needed 1,500 hours of trained flying. This is where companies like Bye Aerospace can help invigorate the field, making training cheaper and the field more forward-looking.

  • Western Water Managers Bet On Cloud Seeding, Despite Gaps In Science

    In the American Southwest, state water managers have been investing for decades in weather modification programs, otherwise known as "cloud seeding." Colorado River Basin states recently agreed to expand that effort, hoping to build crucial snowpack. But some scientists are skeptical that cloud seeding can produce reliable supplies, citing huge data gaps.

  • Beet juice, molasses and mag: Colorado's search for the right highway de-icing mixture

    As Colorado searches for the most effective and efficient de-icer for its winter weather, the state weighs the pros and cons of using agricultural by-products like beet juice and molasses as base ingredients. The quest for finding the perfect de-icer comes up against environmental concerns – especially considering the robust outdoors of Colorado – as well as budget limitations and effectiveness.

  • How Poop-Eating Worms Could Help Save Thousands Of Lives Each Year

    The Bill Gates Foundation is currently funding a number of organizations that seek to solve the rate of open defecation by creating low-cost toilets that utilize the feces within them. One organization, called Sanergy, operates in 11 neighborhoods across Nairobi and uses a systems-based approach that takes into account financing and maintenance of the toilet as well as selling the waste as fertilizer. Another, called Tiger Toilets in India, uses a septic tank toilet that places worms within the drainage layer who then consume the feces and produce fertilizer to be used or sold.

  • Bringing back historic wildlife migration corridors to the mountains

    In North Carolina, a group of planners and conservationists are working to install wildlife corridors along a stretch of I-40, allowing animals like elk and bears to cross safely. The plan has myriad benefits: stopping fatalities, reducing traffic accidents, and improving wildlife habitat. Climate change only makes such corridors more crucial, because wildlife will be increasingly on the move.

  • How a Louisville company aims to make electric cars cost less and drive farther using technology from CU

    Solid state battery technology is gaining momentum towards positively impacting electric cars in both cost and distance efficiency. In Louisville, Colorado, one company is looking at expanding this momentum by raising funds to build the largest solid state battery factory that is focusing on making "light, fast-charging and, hopefully, cheaper batteries for electric transportation, from next-generation electric vehicles to drones or even electric airplanes."

  • Smart ships using wind and bubbles to save fuel

    The shipping industry has made moves to halve fuel consumption by 2050. With a few clever technological innovations--bubbles and rotating sails--ships are closer to that goal. But whatever the promise of these new technologies, they're not yet cost effective.

  • Climate-Positive Architecture Has Arrived In Norway

    Powerhouse, a collective of architects, engineers, environmentalists, and designers based in Oslo, reimagines building design to address climate change. Not only are many of their structures energy-neutral, but they actually produce surplus energy. For example, Powerhouse Brattørkaia in Trondheim is an eight-story office that will generate 485,000 kWh annually. Such "energy-positive" building has made great strides in Norway.

  • Betting on a new way to make concrete that doesn't pollute

    Solidia, a cement and concrete technology company, is changing the chemistry of how cement is created that could make the building material cheaper and reduce carbon dioxide emissions. Cement plants create more carbon dioxide than any other manufacturing process, so the American-based company is testing how to use the greenhouse gas to incorporate it into the mixture instead of releasing it into the atmosphere. So far, it can reduce as much as 70 percent of CO2 that is normally emitted from the process and it's faster to make than normal concrete.

  • Meet the Young Alaska Natives Pursuing a Successful Career in the STEM Fields

    The Alaska Native Science and Engineering Program is working to provide full scholarships, a strong STEM background, and most importantly, a sense of community, to the majority Alaska-Native group of students in the program. The program's results are impressive - ANSEP students "outperform students of all backgrounds in math and science" and groups around the country are trying to emulate those results for other disadvantaged and negatively stereotyped groups.
