  1. Which one is it? Is it Legend? The prerecorded R2R is just down right unbelieveable.
  2. The sonic boom of these modern wing designs (Boom and.Lockheed) are 30X quieter than the Concorde, they will get FAA approval to fly supersonic coast to coast along special corridors that avoid big cities. The wing design that will allow this to happen . . . courtesy of NASA. Nearly 400 million has been budgeted and approved for NASA to go from model to build demo plane and test over cities.
  3. I will be there right with you. That's a guy who influenced all of Rock and Roll.
  4. Freight rail builds and maintains all of their tracks and they own the land the track is on. (The land was a subsidy, but that ended in aboiut 1900). The only indirect subsidies they receive are whatever government contracts they get to move stuff. Rail is much cheaper per mile on long haul than trucking. Trucking on the other hand only pays about 60% of cost of roadways. The other 40% is paid by non-users. Passenger air travel only covers about.50% of cost of FAA. The B2 may be ancient but it is our most advanced long range bomber until the B21 comes on line. The latest B21 drawings in Aviation Week have seats and controls for a pilot and co-pilot.
  5. I'm referring to the Boom jet out.of Denver...Virgin Atlantic has ordered the first 10 and JAL has ordered 20.
  6. Rail freight gets no direct subsidies. Trucking companies are massively subsidized by the difference in motor fuel tax collected and the greater amount spent on road construction and repairs.
  7. It's to be able to walk away from the landing. All of those autopilot settings are entered and adjusted during flight by a human. They crashed a B-2 right after takeoff because of misreadings in the sensors. The problem is you have to automate for contingencies such as the instruments and gauges are supplying incorrect information. You also have to automate for loss of power on one side, and also total loss of power. With a total loss of power it has to pick and find a safe place to land, it has to dump fuel, and about 100 other things. It can be done, but planes are not flown in an autonomous fashion. Just the opposite, a Captain is there in case something goes wrong and a First Officer in the event something goes wrong with the Captain. Military drones are not even automated. When that happens you might begin to see it move towards civilian aviation.
  8. https://www.theverge.com/2018/1/31/16956902/california-dmv-self-driving-car-disengagement-2017 GM and Google are leading the pack. Tesla's testing model is downright scary.
  9. I agree, especially if they get supersonic flight approved over US. We are too large, too spread out for HST. The ROW would be cost prohibitive alone. That's for passenger travel. I think rail freight will be around for quite awhile until something can compete with the pricing.
  10. Look at Whitaker Brothers, that is where we get ours. I'm not familiar with the Royal Brand.of shredders.
  11. Paul Jacobs, president and CEO of.Klipsch sits down with the comedian Dean Delray for an interview. An in-depth talk about Klipsch, specifically Heritage, the Museum, audio of 70s and what the vinyl resurgence has done. A lot of laughs along the way, that Dean Delray is pretty dang funny. He talks about listening to his Cornwall III's for the first time, I wonder if he ever got a chance to listen to Forte IIIs? For sure worth a listen. The interview starts about the ten-minute mark after some commercial endorsements. https://m.soundcloud.com/deandelray/380-paul-jacobs-ceo-of-klipsch
  12. It has nothing to do with unions. I posted on the Railway Safety Act of 2008 in this thread about 20 or 30 pages ago. It required full compliance by 2015. That was extended until the end of this year, and it will have to be extended again. It is an unfunded mandate that carries with it the problems with all unfunded mandates. There are major technological problems and compatibility problems, and Congress isn't giving enough money to the FRA to develop a uniform system where trains from different systems can talk to each other and how. Some of the proposed systems EXCEED the cost savings from the avoidance of accidents.
  13. There is no money for it. The collision avoidance system for passenger trains was mandated by Congress but it keeps getting extended because there is no money for it. Safety has always come from two primary sources, tort litigation and legislation. It rarely, if ever, comes from a company saying "I'm going to make a safer mousetrap even though it will cost more and we will sell less." Profit motive and safety are diametrically opposed, that's just a fact of economics. That alphabet soup, FAA, EPA, OSHA, NIHTSA, etc. were all created to regulate various private sectors because a free market is incapable of regulating itself. The only reason any A/V manufacturer will produce a safe car is because they have to comply with regulations and because of product liability exposure.
  14. No no no no no no no. Flight is much, much more difficult. The only thing that has been automated is engine and fuel management which takes a crew from 3 to 2. There is no fail safe option like you have in a car (press red button and it safely pulls over to side of road). The autoland function isn't even automated, it has to be carefully set up by pilot and, as you point out, requires a sophisticated ILS system be installed at that particular airport. A vehicle only has 3 main decision inputs power/acceleration, braking and steering. An airplane has roll, pitch, yaw, lift (angle of attack and flaps), drag and power (X2 engines). The most sophisticated flight automation engineers in the world are at JPL, and they don't do any flights fully automated. Lots and Lots of people doing lots and lots of things.
  15. With the age of that home they probably used horsehair rather than asbestos, but regardless, you want a good respirator with ANY dust, even sheetrock. I am hoping Dave doesn't plan to touch any of those walls.
  16. Lath and plaster, most in South is lime because it is so abundant. Howeve, I just learned plaster can be concrete based. It all disappeared after the advent of sheetrock. Now if you have a POPCORN ceiling it is most likely asbestos. That is a beautiful home.!
  17. It is for sure concrete and not plaster?
  18. Love it. What's the story on the concrete walls? Never seen or heard that before, other then dorm rooms and military housing.
  19. Great project. Do you have your spreadsheet started that you can post? That will get us started and we can start to figure out what's missing. Travis
  20. You got spoiled driving my Jag @DrWho Your standards for luxury cars are way too high now.😀
  21. Not in this. This is software intense, and processor dependent. Lots of IP and patent potential.
