With the Solar Light Cap (ThinkGeek, $34.99), you can store and conserve energy without having to lift a finger. How great is that? This generic looking baseball cap has an integrated solar panel and two LED spotlights in the brim. So picture this: you’re walking around outside on a beautiful summer day (with your hat on because it’s super sunny out) and then later that night, you’re trying to find your keys that fell out of your pocket. Hmm, if only you had a portable flashlight at your disposable, right? Well, you do. Since you were out all day in the sun, the solar panel sucked up all the sun’s nutrients and with about two hours of charging, your hat has enough power to light up the night for 2 to 18 hours (depending on brightness setting). The two LED lights are controlled by a button on the hat’s brim, which allows you to change brightness as well as change the lights to a flashing SOS mode in case of emergency. The hat is fully sealed and waterproof, so you can wear it in the sunny afternoon to charge it and still be able to utilize the LED lights on a rainy evening.

Didn’t I tell you that you could be as non-proactive as possible, and you could still help the environment with this product? I mean, this hat’s maximum run time on a full charge is 36 hours. 36 hours! Do you know how many batteries and how much outlet power you’re saving just by being your sloth-like self? I bet you didn’t know you were such an environmental activist. Pretty soon you’ll be holding pep rallies and protesting in the streets.

5 out of 5 eco-friendly stars.
