Contribution of energy to an intelligent electrical network through an exercise apparatus

This invention describes an exercise machine that turns human or animal effort into electricity. When someone exercises on it, the machine captures that energy and sends it directly into a smart electrical grid. The design specifically includes a heavy spinning wheel (flywheel) to store some of the energy and make the power output smoother and more efficient.

Why it matters: Since 2010, smart grid technologies and the infrastructure for connecting distributed energy resources have significantly matured, making the integration of small-scale power generation, like from an exercise machine, into the electrical network much more practical and efficient. The cost and availability of grid-tie inverters have also improved.
