Nanotechnology holds out the possibility that the surface of a device will become a natural source of energy via a covering of “Nanograss” structures that harvest solar power. At the same time new high energy density storage materials allow batteries to become smaller and thinner, while also quicker to recharge and able to endure more charging cycles.

Another alternative is called energy harvesting. This article lists the following type of energy harvesting:
- winding
- solar cells
- ambient RF
- motion based generators
- thermoelectricity
The following diagram from the article shows the order of magnitude in energy which can be harvested:
