Winning Science August 28, 2013

This is my favorite kind of science. I love it when stuff is smashed, broken, blown up or otherwise destroyed. This NASA drop test was performed locally at the NASA Langley Research Center in Hampton, VA.  Dropped from a height of 30 ft. the chopper crash was intended to determine the impact on an airframe during a 30 mph crash.

They even used an Xbox Kinect to help record the crash. Way cool.

I hate to vacuum and dust. I’ve thought about getting a Roomba, but I’ve never thought they were very practical. This however, might be something interesting. This Roomba like device sends out little drones covered in a gel that makes dust stick to it. The drones then return to the base station and get the dirt removed.

If dirt sticks to the gel, I wonder what else does. Am I going to find one of these things rolling away with my cat attached to it?

The events that lead up to the March 11 nuclear disaster at the Fukushima Daiichi plant are pretty well known at this point.  Unlike several previous nuclear accidents, there was no hiding this one. While the events unfolded on international TV, we are only just now beginning to evaluate the long term effects of this unparalleled event. Popular Mechanics has an article out this week that talks about some of the potential effects of radioactive water and some of the possible technologies that can be used to combat the threat.

I also enjoyed the fact that the article was written by someone who was at one point associated with the US Navy nuclear program. It gives me confidence that he knows the subject matter (plus I understood what he was talking about).
