ELECTRIC FLIGHT SIMULATOR 7-13-14
Flight simulators for commercial and military pilots have been using platforms
mounted on what's called a hexapod table which consist of six hydraulic
cylinders that create the motion. However, with the advance in electric
motor technology, they are replacing the hydraulic cylinders with electric
drive shafts on ball screws. Magnets made of a rare earth material called
neodymium is what makes this all possible.

It's not raining and a nice blue sky. Let's go for a ride before the severe
storms come in. I heard last night that 30,000 up northern NH were out
of electric power until this morning. Trees uprooted in Ohio and Pennsylvania
and Maryland. Fortunately, we haven't had any major damage around the seacoast
area. The winds today were out of the west gusting to 18. Here's a few
pics of the day.
