There's a new roller coaster at an amusement park in Surrey, England that charges your phone with FEAR.
They had scientists develop tech that takes the vibrations from your screams and converts them to energy to power up your phone. Obviously it'll only be a small battery boost, but on a long day at an amusement park, I guess every bit of juice is helpful.
There's no word on whether the technology could make its way to the rollercoasters over here in the U.S.
