Solar Charging Trailor

I'm already getting Burning Man brain (even though I won't be there until the end of August).  Power is always one of the biggest challenges of our camp, Freestyle Palace.   My hope is to eventually power our lighting at night with a battery that has been solar charged during the day.  This would really save the wear and tear on our smaller generators and also save us a lot of gas.  I came across this video showing how to make a home made solar trailer. This would be perfect!!  

Charging a phone with a candle, harness that heat!

This video shows how you could harness the heat of a candle to charge your cell phone, you know if you should ever need to do so.  It is a really cool explanation of heat and electrical charges, also the use of peltier devices. Check it out! This video was featured on Tinkernut and LifeHacker two really cool DIY sites.
