In 1901 P. Jassmann (what a cool last name) invented what is know today as the roller blade. Only his invention leverages the bouncing motion of the rider to propel the wheels. He says, "The object of the invention is to provide a new and improved roller-skate which is simple and durable in construction, easily constructed, easily attached to the foot, and arranged to transmit the downward motion of the foot-rest to one of the wheels to propel the roller-skate and the skater at a high rate of speed.
Today 111 years later we have the "Land Roller" with a foot rest and two wheels with spokes.What if Jassmann's regenerative motion could be applied to a modern day polycarbonate graphite roller blade, how cool would that be? There is always room for improvement.

"It isn’t necessary to be an inventor to be an entrepreneur nor is it the hardest part. There are many, many inventions lying around that can be picked up and applied to a market problem. These include inventions that can be licensed from companies or universities, inventions from other industries or geographies that can be applied in a new market, old ideas that can be applied in new ways, and many other sources."
