A human-powered vessel is the best way to travel without any carbon footprint. This might be the idea of Italian innovators in Carlo Ratti Associati after it proposed a 65-feet-long boat that could hold up to 45 people and exercise gear attached to a generator that collects kinetic energy to power it to its destination.

According to Bored Panda, the vehicle is named "The Paris Navigating Gym" and harvests human workout energy to propel the boat. Ratti said the boat is "fascinating" as one can see the energy generated by a gym workout could really propel a boat. According to Ratti's designers, the first prototype could be built within 18 months.

Aside from its gym equipment installed near open windows that showcase the views of Paris through a river, the Paris Navigating Gym can still run its engines through the photovoltaic cells on its roof collecting solar energy to fill its generators. The boat's idea also helps inspire people to exercise more; seeing better views while on an exercise bike is an amazing way to take one's mind off biking and lose lots of weight.

According to Business Insider, the the gym would travel along the Seine River passing through several amazing Paris city views. The wide river can accommodate many more floating gyms in the near future. Depending on the public's support, the boats can be produced quickly and effectively boat as a global warming deterrent, a health improvement vessel and a tourism craze for the city.

The gym's workout bikes would come with augmented reality screens that would show information about the weight the biker loses. As one enjoys the view of Paris from the river, one also sees how much energy he or she is saving by using the bicycle and how much more he or she needs to gain a free pass to the tour using the bicycle.

Human-generated kinetic energies is an untapped market for improving the world's environment and climate. According to a research by Columbia University, a modified fitness tech could fuel a wireless network link in the near future and believe it to be a key component in the future's wearable computing and "Internet of Things" technologies.
