We’re clearly solar advocates, and 99 percent of the time we take the topic seriously. For the other 1 percent, here is your weekly whacky use of solar power:

…the Ultrasonic Solar Animal Repeller!

Just what you always wanted, right? This unexpected device emits ultrasonic sound waves that are unpleasant to animals but imperceptible to humans. It uses a tiny solar panel to generate the electricity it uses, and the device claims to keep deer away from flowers and neighbors’ pets off your lawn. Just think, you can even use renewable energy to keep raccoons out of your garbage.

For those who are interested, this device is available at animaloff.com. Happy Friday everyone!
