For those who love model trains,
here's a peek at the future - a solar-augmented monorail. Joe Kopacz and his
brother Justin created the monorail from scratch. Joe, a mechanical engineer at
Colorado State University, created the gadget for a school contest. The
monorail includes break regeneration and has solar panels to augment the battery.
The monorail is run off of an arduino uno, which controls the recharging and
other special features - including lights that come on when the monorail enters
I guess the future is now. This is certainly a long way from the trains I had as a kid. Even later on when a buddy of mine got into model trains for a while they were not like this. I have heard a lot about the arduino technology but have not tried my hand at it yet. The solar aspect of this is interesting as well since I am seriously considering some home improvements that would include some solar PV installations. Here in Florida any power sold back to the utility is at the same rate we get charged for it so it is a pretty attractive proposition once all the state and Federal incentives are added in.
I am just not so sure how a real solar train would work out.... :-)
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. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
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.
