Solar powered mobile units.

The major problem is power levels but, major improvements in solar voltaic cells may be designed to meet the power needs of portable devices.

A conversion phase from old Ni-MH to solar would be needed.

Crystal cut plays w/refraction better than plane flat surface.

True Black is available now.

Conversion phase (mainly for financial reasons of the battery industry) can recharge old NiMH on the road. These units users can carry in their pockets, place under natural or article light to power and attache it to the old battery unit to recharge it which can be done while in use.

Mobile manufactures create a power supply unit (ideally externally for cooling reasons and very thin) on the device that allow the user to slide in and out solar power units of varying voltages (3.5 - 4 volts) which should have at least a 6 month life can be designed for the final phase of solar powered units for mobile devices. They should be interchangeable on different devices.

There should be a conversion phase recycling infrastructure with aspects that later become the recycling infrastructure of the final solar powered mobile units phase. The crystal top, the cell itself, the casing all recyclable materials.
