Energy harvesting of the RF fields has been proposed to power small milliwatt RF amplifiers. In this work we demonstrate that the time-varying gradient fields can deliver much higher power levels up to a kW which we used to energize a conventional drip coffee machine. A large pick-up coil was designed in which voltages of 100-200V were induced by rapidly oscillating gradients. The coil was connected to a commercial coffee machine in the magnet, and coffee was prepared in and with the MRI in just 5min.
