Long Walk

"This Is the Longest Walkable Distance on Earth":
The total trip is over 14,000 miles. A real person walking this route at a sustainable pace would need about three years to complete the trip. They’d need to pack a variety of things or, like in the award-winning game 80 Days, sell their stuff and buy new stuff along the way: desert gear, rain gear, and even body armor for the sections through anarchic or war-torn regions like South Sudan.

It's Mom!

As we approach Christmas day, I wanted to share one of my favorite C-SPAN political clips of all time. 

Two brothers and pundits with diametrically opposed political views were appearing on C-SPAN just before Christmas time, when a familiar voice called in to give them a piece of her mind:

One Step Closer To Self-Replication

"This 3D-printed Stanford bunny also holds the data for its own reproduction"
The fabricated Stanford bunny holds about 100 kilobytes of data, thanks to the addition of the DNA-containing nanobeads to the plastic used to 3D print it. "Just like real rabbits, our rabbit also carries its own blueprint," said Grass.

Grass and his colleagues were also able to cut off a piece of the rabbit's ear to retrieve the embedded DNA. Then they used that information to fabricate a second bunny, repeating this process four times, for a total of five fabricated bunnies. The data did degrade a bit with each subsequent generation, but the decoding program can fill in any blanks so that useable data can still be retrieved.

More Exoskeletons For Augmented Strength

"Sarcos Demonstrates Powered Exosuit That Gives Workers Super Strength":
The Guardian XO can augment the strength of the user all the way up to making a 200-pound load feel like it weighs zero pounds. Typically, this is not how the exoskeleton works, though, since it can be disconcerting to be lifting something heavy and not feel like you’re lifting anything at all.

It’s better to think of the exo as a tool that makes you stronger rather than a tool that makes objects weightless, especially since you still have to deal with inertia. Remember, even if something has no apparent weight (either because you’re in space or because you’re holding it with a powered exoskeleton), it still has mass, which you have to be aware of when trying to move it or stop it from moving. The amount of help that the exo gives you is easy to adjust; it’s got a graphical control panel on the left wrist.

Gravitational Energy Storage

"How UK's disused mine shafts could be used to store renewable energy":
The surprising new source of “gravity energy” is being developed by Gravitricity, an Edinburgh-based startup, which hopes to use Britain’s old mines to make better use of clean electricity at half the cost of lithium-ion batteries.

Gravitricity said its system effectively stores energy by using electric winches to hoist the weights to the top of the shaft when there is plenty of renewable energy available, then dropping the weights hundreds of metres down vertical shafts to generate electricity when needed...

Charlie Blair, Gravitricity’s managing director, said: “The beauty of this is that this can be done multiple times a day for many years, without any loss of performance. This makes it very competitive against other forms of energy storage – including lithium-ion batteries.”
