With all the new ways of making
ethanol and your hydrogen ideas, if we would start drilling our own oil to fill
the gap until we have all these other renewable fuels we could be energy
independent in less than 10 years. But we do need to use all of our available
options to get there. Oil, coal natural gas, solar, wind hydrogen and nukes
should all be used to give us energy independence as quick as is possible. I
have done a little research on the subject and it appears to me that we have
more oil reserves than any other country in the world and I think they should be
used. There is not a lot we (US) can do about climate change until
China and India decide to

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10.

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
