We’re sure that each country has something to impress their tourists with: each place has some great ideas that could actually be used everywhere. We think that a tank style dolly for stairs, trash cans with Wi-Fi, and “thank you” buttons for bus drivers should be used by all people all over the world.

Enlighten has collected some interesting ideas from different countries that can make our lives easier, brighter, and comfier.
