Rethinking Transportation 2020, page-18

Once in a generation shift, smart or lucky to be on anything going in the right direction, copper is a key transfer agent. In less than 15 years it will not be worth drumming any oil, bulk may still survive a few years longer. Fossil fuels gone, kaput!!, Think solar, wind, hydro, tidal and than when folks stop needlessly wetting themselves nuclear fusion will allow for some nazzi travel speeds. Batteries will develope so fast (next 5 years) in performances that solar collection will rule for a generation. Maybe in 10 years in a place like Australia you will not be able to build a house without solar tiles and a local electric storage system.

But here sit in your hands boys n girls you are going to love this ride. Just try to have a longer attention span that some we see here.

Cheers
Phil.
