Trek and Bontrager have developed a new cycling helmet technology that looks to dramatically improve performance and safety. Dubbed WaveCel, the new tech uses three processes – flex, crumple, and glide – to disperse the energy absorbed on contact in an accident, providing up to 48 times more protection against head injury.

From light-scattering aerosols in Earth’s upper atmosphere to artificial chemical sponges created to suck carbon-dioxide out of the air we breathe, geoengineering aims to purposely change the world's climate using technology. Here's why its proponents think it must happen.

When he was 13 years old, Christophe Debard had his leg amputated. Jump forward to the present day, and his experiences have led him to create the startup Print My Leg. It offers open-source designs for 3D printed leg prostheses to whoever needs them. Welcome to a growing revolution.

Using machines that resemble jet engines, Climeworks wants to fight climate change by extracting CO2 from thin air. The gas can then be sold to carbonated drink and agriculture companies, or sequestered underground.

In 2013, Boyan Slat crowdfunded $2.2 million to fund the Ocean Cleanup, a non-profit organization that builds big, floating trash collectors and sets them out to sea, where they’re designed to autonomously gobble up garbage. The organization has since raised over $35 million and a lot of questions from incredulous experts.

In order to transition to a more renewable-focused energy system, we need to scale up our grid storage capacity -- and our existing methods aren't going to cut it. Could compressed air be the key?
