Hexatron

A couple of weeks ago, I went with EAA Chapter 23 to see the manufacturing of a small experimental aircraft engine, the Hexadyne P-60. 

The successful development of an aircraft engine is a difficult and complex task.  Hexatron appears to have done that.

Successfully (meaning profitably) marketing an aircraft engine is a miracle.  I don't think they are close to that yet, but I did enjoy seeing the factory.

And in case anyone from Hexatron Engineering reads this blog, I have some very helpful ideas on accomplishing the miracle part.  Please contact me through the comments section.

Helo

This helicopter was flying around my neighborhood for a couple of hours on Friday.  I don't know what it was doing, but you can find the N number registration here.



But a quick trip to the www tells me that the device on the front of the helo is Lidar.

And I found out that Merrick uses the helicopter and Lidar to map transmission lines, which it must have been doing for the new Populus to Ben Lomond line, that I have written about before.

Boiling Water to Make Ice? The Answer.

Yes, Virginia, it is possible to make ice by boiling.  I will demonstrate.  Start with some water.  I used some bottled water and measured the temperature at 60°F.

 
Then, put a small cap-full of the water in a vacuum chamber and pump it down.  Sixty degree (F) water boils under vacuum. 
Continue pulling vacuum until the boiling stops. 



Now, release vacuum and measure the temperature of the water.

The temperature has dropped 14 degrees by boiling away some of the heat under vacuum.  Pull vacuum again and release and see what happens.

 
 There you have it, ice by boiling water.
