A group of researchers at the Oak Ridge National Laboratory's Department of Energy have created a futuristic new platform which allows a 3D-printed house to fuel a 3D-printed car and vice versa. This new energy system is dubbed Additive Manufacturing Integrated Energy or AMIE, and comprises special technology that allows for a bi-directional flow of energy between house and vehicle.
The system uses a special resonant technology that is highly efficient and allows for the car battery to power the AMIE platform or vice versa.
The development of the AMIE energy platform is still in its early stages, so don't expect this to become available any time soon. However, the real hope here is that the technology inspires intelligent questions, and perhaps drives other people to come up with new and innovative applications for it.
