The Personal PowerCart (PPC) is mobile and can provide electrical back-power in case the electric power grid goes down or as a stand-alone power system in remote locations. The PPC is now in production in Northern California. We are also launching the Personal PowerBike (PPB). This is an electric powered bicycle that can be driven as a vehicle. It can also be mounted on a stand indoors and can generate about 100 watts comfortably by a rider. The energy from the bike can recharge the bike battery or can recharge the Personal PowerCart.
