Perhaps you thought An Inconvenient Truth was an ecological wake-up call. Well, this is, too–literally. The Ecological Earth Alarm is a concept design by Petr Kubik shaped like the planet Earth, powered exclusively by solar energy.
According to Green Cleaning Ideas, the concept is pretty simple: leave the spherical alarm clock in the sun, and it wakes you up in the morning. The concept makes use of solar panels in funky shapes and an OLED display, encased in silicone–which, according to the designer, makes it like the Earth, as “this spherical clock has got (sic) its own protective atmosphere.”
As an added bonus, the Ecological Earth Alarm will right itself if you happen to knock it over while stumbling blearily home house at night. So even though it’s spherical, you won’t run the risk of waking up at 9:00 AM instead of 6:00.
