We mounted our solar-powered wind turbine toy onto the dashboard of our VW Beetle, and get a lot of questions wherever we go. "What is that thing for?" Show everyone your support for renewable energy, and put one in your car too!

What would the Earth say to humans if she could talk?

This is a video overview of the 2007 Solar Decathlon, held in Washington DC, narrated by 8-year-old Carrick. The flute music is courtesy of the Burnt Earth Ensemble, at www.burntearth.com

Carrick interviews Darth Vader, who is now heading up the Chevy Volt program at GM. I hope GM has a good sense of humor...

My son and I made this video for the 'Convenient Truths' contest at http://truths.treehugger.com/ It features our yellow Beetle that runs on vegetable oil, and the larger possibilities.

This is the first time that scientists have reached a consensus that global warming is real and that we are causing it. In 14 years, Carrick will be a grownup, and in this video he talks about what he expects the grownups to get done in the meantime.

Over 10,000 moving parts in a piano work together to create beautiful music - if we all worked together for a more sustainable world, how beautiful would that be? This is a video made for the Current TV Ecospot contest submitted by my friend Chuck.

I helped my friends Anna and Victoria make this video for the Current TV Ecospot contest. The music is by a talented friend Barry Hall playing the flowerpotophone - see & hear his unique clay instruments at www.ninestones.com

Making his video debut, my little brother Gareth! Gareth shows his wind-up flashlight - if you wind it for a minute it lasts for a whole hour, no batteries required.

8-year-old Carrick stars in this trailer for an upcoming video, tip of the hat to Mr. Gore of course. As the youth become more aware of climate change and understand how much it impacts their future, their voices will be impossible to ignore.
