Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
According to Facebook's own advertising department, on the average, about 15% of the folks you imagine are getting your stuff are getting it. The other 80 or 85%..... not. That's one in five if you're lucky, one in seven if you're not. Ever wondered what that “promote” button at the bottom of your posts is? That's the doorway to talking to ALL your followers or friends or fans. It's the ONLY doorway, and it's a toll booth. This is not a bug, it's a feature.

There is a 250 volt battery with a huge amount of potential energy. You have basically a medium size bedroom full of batteries that are 6 feet tall.
The battery can keep the lights running for about 1.5 hours while also supplying power to move it through the water and power the reactor plant to do a restart.
We calculated one time that if all the energy in the battery was released at once (not possible, we knew that), it would blow the sub 1.5 miles into the air.
