So we should all just give up? Economy is pretty dependent on gasoline/oil too; but I'm glad people are looking into finding better sources of energy. We know gasoline burning & the process of obtaining oil is not good for humanity for a big list of reasons. _If_ it's found cellphones can be harmful, hopefully we begin researching how to make safer versions. Personally, I think there's been enough studies on it to make it at least plausible and I choose to error on the side of caution.
Say, have you heard about the microwave background radiation? You are being exposed to radiation in all microwave frequencies from all directions right now from the fusion of nuclear isotopes at the start of time, also, would you like to buy this giant Faraday cage.
