UB-110 was a Type III U-boat. It was sank on July 19th 1918, was probably the last u-boat sank during world war one. Twenty three of her thirty one crew died during her destruction. On October 4th 1918 she was raised from her watery grave and sold for scrap metal. 

These pictures were taken just prior to her being broken up for scrap. They show the cramped conditions on board that the crew had endured.

Device Captures Energy From Chaotic Motion

Though we go scrambling for an electrical socket or a new battery when our smartphones or other electronics need a boost, the energy to do the job is all around us. A ship bobbing up and down in the water or a jogger running in the park unleashes enough energy in their movements to potentially provide usable power. If only we could figure out how to harness the energy unlocked by chaotic movement and store it for use when it’s needed.

The machine above is called the WITT (Whatever Input to Torsion Transfer) device. It consists of two pendulums, which pivot around shafts that transfer chaotic movement in any direction to an attached flywheel. The torque from the spinning shafts is funneled into spinning the flywheel in a single direction, which stores energy in its rotation. That stored energy can then be tapped to generate smooth power output. Two patents have been issued for the chaotic motion energy harvester. Learn more below.

Watch: This revolutionary technology is changing the world for kids born without limbs 

That’s awesome and I’m sure its way cheaper than a prosthetic, but seriously it cannot be cheap to 3d print something that big…

this one 17 year old guy 3d printed an entire arm and shoulder for himself and it cost him $250

this seven year old girl got half an arm (just like lusie in the gifs) 3d printed and it only cost $50

can we just compare that with the average price of buying a prosthetic

3d printing is gonna help so many people holy crap

“Education changed the lives of my entire family. Before education, we knew only how to work. It was always very quiet in our home. My grandfather was a laborer, but he paid to send my father to a tutor so that he could learn to read. He told my father that, if nothing else, he should begin by learning how to read and write his name. When I was born, my father taught me how to read. I started with local newspapers. I learned that our village was part of a country. Then I moved on to books. And I learned that there was an entire world around this mountain. I learned about human rights. Now I’m studying political science at the local university. I want to be a teacher.”
