Earlier today something prompted me to compare Honeywells HW2000i portable generator with Hondas EU2000iA portable generator. Then tonight this "PowerWagon Gasless Generator" caught my attention. Before buying the Pup we were looking at different types of campers including the "Little Guy" Teardrop trailer, and every once in a while I get an email from Ebay with a listing from Little Guy. Tonight I got this email which shows their prototype, "Little Guy PowerWagon Generator Teardrop Camper Trailer", which is where I found the link for The PowerWagon Gasless Generator. "The PowerWagon Gasless Generator" is a small trailer that as you tow it around the motion of the wheels going around (8 MPH minimum speed required) charges a bank of deep cycle batteries. I'm still looking through the site but it looks like it comes in either a 3500 watt or 5000 watt model, and could last a few day camping on a single charge which requires 50 to 70 miles of travel. What do you think? Imagine if as your driving to your camping destination and the wheels on your popup were storing enough power for your entire trip. I think it's a great idea.
