These are mineral crystal-powered generators that generate electricity. This energy can also be derived from people power. Did you know that we generate electric power when we breathe or when we walk? Scientists are trying to find ways of capturing this energy to put it to use powering cell phones or even larger devices. Here is a video from the people at Fast Draw to tell you more. However, I am not recommending anyone watch CBS News or any programming on CBS, which is advertised at the end of the video. The actual title of the video is "Gossamer Albatross" but there is just a little information on the Gossamer Albatross, and is more about piezoelectric generators and their current applications (watches) and possible future applications.
Here's an article from Wired.com telling more about piezoelectric generators.

Kidsnet.au has some great information for kids on piezoelectricity.

Blog Hop - A favorite recipe... in song!
This is a YouTube video featuring a recipe for one of my all-time favorite foods! Actually, when I make guacamole I just smash up some avocado and add lime juice, minced garlic, some cumin and a little chile powder to taste! I'm the only one in my family who will eat it, so I don't make it very often.
