Thanks for the feed back here.
The goal here is to, as one person posted, use stuff that was being scrapped and keep it from getting to the land fill. The other idea is to make trailers with a higher payload capacity and more versatility. These designs are geared towards people who put their trailers to work. The basic front fork model has a 200 lb capacity, future models will haul up to 500 lbs. If you think that's too much go watch a pedicab operator. The carts are also built with the idea of being used as a wheel barrow in a garden, or farm to market application, or a shopping cart at the market. They can be fitted with bins to carry and even display produce and other items so they become the "fruit stand, knife sharpening station, bike repair shop, etc, when detached from the bike.
