Although it's not as stylish as the UFO Cap Umbrella, the Umbrella Shoulder Holder lets you keep both hands available. Just plug your umbrella into one end and wrap it around your shoulder.

The T2K Tsukuba System is a 640-computer cluster with a processing speed of 95 trillion floating-point operations per second. The T2K calculated a total of 2,576,980,377,524 decimal places in 73 hours 36 minutes, which is a small fraction of the 600 hours taken by the previous record holders—Hitachi and the University of Tokyo—who calculated only 1.2 trillion places.
Existing lithium-ion batteries have a cathode that contains graphite and polycrystal lithium cobalt oxide with the graphite improving the performance of the cathode but also requiring space that could be theoretically used to store more lithium ions.
The researchers say it will take up to ten years to develop a cathode with no graphite and single crystals of lithium cobalt oxide but that the end result is a powerful battery for electric cars, which can store 10 times more electrical charge. As a result, electric cars could travel ten times farther than they can today.
