  • You Flushed the Toilet. They Made Some Bricks.

    A civil engineer at the Royal Melbourne Institute of Technology University in Australia is converting biosolids, or disinfected leftovers from the water treatment process, into bricks for building. He claims they look, smell, and work the same as conventional fired clay bricks, but with an added benefit of saving land and energy and reducing carbon emissions.

  • 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.

  • 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."

  • In Nigeria, a green stove addresses health, the environment and employment

    Green Energy Biofuels was created when Femi Oye wanted to find a cookstove that minimizes harm. The cookstove uses biofuel, which reuses waste, and the stove is also safer and more energy efficient. He estimates it has reduced carbon emissions by over 600,000 tons since the company began. Still, one challenge is convincing Nigerians to pay more, albeit for a safer appliance.

  • 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.
