The scientists at Columbia university are working on a project that, in a few years' time, could very well change the way we look at everything.
Depositing spores on plastic tape, they figured out a way to use water as a form of energy. As the air around the tape gets more humid the spores expand, and as the air gets more dry, the spores contract. When you put enough of these pieces of tape together something absolutely mind-blowing happens: movement.
By attaching string to the tape, this "engine" of contracting and expanding tape manages to cause the small wheel in the front to move forward. While this tiny amount of movement isn't much to look at just yet, the implications are incredible and the possibilities are endless.
Whether it be the eventuality of cars that move from this power or the incredible power usage for anyone "off the grid," looking at these tiny vehicles move should fill everyone's hearts with hope for a better tomorrow. As these tiny devices get faster, stronger, and bigger, the whole problem of fossil fuels and the pollution they cause could one day be a thing of the past.
Make sure to look at these incredible little devices if you hope the future will be a better, greener place.
