Any radical transformation of the energy system in the 21st century will require a range of new technologies on a large scale using limited natural resources. For example, thin-film solar photovoltaics (PV) and battery-electric vehicles require rare metals — cobalt, gallium, germanium, indium, lead, lithium, nickel, ruthenium, etc.
As this materials run short, by 2017, “the radio ... the [cell phone, computer game and Blackberry], and the movies that we know, may just be passing fancies, and in time may go.” (With apologies to George Gershwin).
That is just plain silly. First off Lead, Cobalt and Lithium at the very least are fairly common.
Secondly if you can't buy a new cell phone/blackberry/i-phone every six months it does not mean your old one is useless, change for the sake of change is just as stupid as doing the same ineffective thing over and over because it is 'tradition'. I carry a five year old cell phone because I use it to make calls. All the youngsters I work with think I am crazy, but it has been paid off for three years, it works fine, and I do not need it for anything but making calls so why upgrade for a bunch of bells and whistles that would rarely if ever get used?
