Thunderf00t has released another video on the Hyperloop.
In it he takes the fans of Elon Musk to task and references the Hyperloop Alpha Document. I took a look at it and from a professional’s standpoint, it’s a very interesting diagram, but not in a good way.
Pratt has finally completed it’s geared bypass engine for commercial aircraft. The development for this engine has been going on for a long time. There are reasons for that. Some of it’s FAA red tape. The biggest part though, is the expected long life of the engines themselves.
It’s not like the old days where you did all your development in a backshop. Of course the aircraft aren’t enlarged kites anymore either.
At least for the Commuter rail System. All too frequently it doesn’t do what you need it to do and doesn’t go where you want to go. This is especially true for making connections at airports. It’s time for a rethink.
In 1947 the New Haven RR installed a mechanized IBM car forwarding and processing system that used teletype technology. The railroad was apparently very proud of their new system and published a small booklet about it. I found a copy and scanned because it’s an interesting look of how technologies changed business operations and the evolution toward data processing and technologies. It’s also a good look at how the railroads conducted their business in the transition era. It seems that the motive power transition was not the only one happening on the rails, just one of the most visible.
