Is this the greenest road ever? A highway in Korea features a stunning solar-powered bike lane running right down the middle. The lane is offset, protected by barriers, and sheltered by solar panels. The lane runs from Daejeon to Sejong, a distance of around 20 miles (32 km), which is a few hours’ drive from the capital city Seoul. It’s a fantastic idea that could pave the way for similar commuting-style bike lanes in the future.
