RTG palm

Use an RTG or Atomic Battery to keep the Dram active and/or charge the battery
  [vote for,

Simple idea, add a *small* lightweight RTG made from phosphorous, americium-241 and substances which dissolve the phosphorous and americium-241, then use solar cells to produce a * small * amount of power.

You could use the power to keep to DRAM working or trickle charge the lithium ion battery, If large enough it could even power the PDA!

       Just to clarify, this idea is for a nuclear battery for a PDA? But why would you need solar cells as well?

       {kropotkin} it would use solar cells because the “nuclear battery” uses phosphorous and americium-241, which when mixed well, radiate * light * which then is converted into electricity by solar cells

       {humanbean} First off, alpha particles (produced by cheap americium-241) cannot penetrate a piece of paper, i would think that it would not Penetrate the solar cells, or anything else.   

       The cells are expensive- see Mylar, but if only I could get a patent on mine? - (Using phosphorous, it can also be used as a cheap backlight and can be build * dirt cheap *, no idea weather a beta particle source can be gotten at for under that of americium-241. If it ionizes the phosphorous and everything else, Is it possible to use it as a battery, *direct *?   

       *Grams americium and trowel and starts spreading on solar cell (with particle mask of course!) *
