Hiroshima University – When natural disasters hit, they often destroy bridges first. So engineers from Hiroshima University in Japan set out to build a quickly built, strong replacement. Inspired by origami, the new mobile bridge spans 56 feet and takes three people less than an hour to deploy. Often no foundation work is needed, making it ideal for areas affected by earthquakes or floods. Made of aluminum alloy and steel, it’s lightweight and easy to transport, yet sturdy enough for cars to cross.
Onyx Solar – Solar panels are practical, but they’re limited up there on the roof. Onyx Solar developed an outdoor photovoltaic flooring that picks up the slack: Solar cells inside the anti-slip glass enable decks, balconies, and walkways to draw energy from the sun. The power can be stored in a battery or, when connected to a building’s electrical system, sent straight to outlets. The floor can produce 5.6 watts per square foot (enough to charge a cellphone), supports up to 881 pounds, and comes in more than 1,500 colors
