  3. Rail works great for really long haul freight. Especially bulk cargo. But there are loads that are going long distance that are better moved by truck. Especially loads that may be time sensitive.

  7. And then the Internet via YouTube allow idiots to post videos of themselves doing really stupid stuff while there buddy carved their tombstone. Hence "hold my beer" and "watch this" became memes

  10.  @matthewcarroll2533  I'd love to see this come about. Will it? Hell, I don't know. One thing imo is recharge time. The other is how long they hold a charge

  11. The problems with the whole JWST are a national embarrassment. From the ever changing requirements of the SLS in terms capabilities required to NASA's seeming mismanagement. I've come to the conclusion that certain members of Congress who happen to represent Alabama and districts in it who could care less if SLS ever flies as long as NASA facilities at Huntsville keep running and administrators at NASA who might find themselves out of a job if their program ever really finishes development. Add in the fact that NASA gets treated like a political football. Different administrations pushing different adgendas. Supporters and opponents getting elected or leaving office. Maybe its time to cut the agency up into seperate ones. That or give the agncyclear marching orders and let them get on with the job.

  12. If the manhole covers (both of them) got blown into space they may well of exceeded Solar escape velocity and are now on their way to the stars. Now we just need to figure out the vector

  13. Of all know supervolcanoes there are more of them in Western North America than any where else*. I suspect this has a lot to do with the remnant of the Jaun de Fuca plate and perhaps other subducted Pacific Seafloor Plates that are still in the process of being absorbed back into the Mantle. But Yellowstone is a whole different ballgame. The hotspot that feeds Yellowstone has been active for a very long time. As North America has moved slowly to the Southwest due to its Plate motion the hot spot has repeatedly burned through the overlaying North American Plate leaving a trail of old caldera. Plus the hot spot likely fed the great Flood Basalts that buried parts of Washington. The only reason that the trail of old caldera fo not trace a fairly straight line to the Southwest is that the Pacific Northwest is rotating slowly in a clock wise motion. Approximently 50 million years ago the west coast of North America was in Eastern Eastern Washington. Various chunks of continental crust and island arcs have slowly been acreated to the western edge of the continent as the North Ametican Plate over ran the subducting Juan de Fuca Plate. One of the largest of these was a large volcanic province known as Siletzia. Portions of which comprise the Olympic Olympic Peninsula of Washington. For a good channel one PNW geology visit Nick Zentner's channel. He's a geology professor at UW Ellensburg *Yellowstone, Long Valley in California and Valles Calderas are just three. Some of the known North American supervolcanoes are likely extinct. Although there has been some activity in historic times. The various cinder cones in areas of the American West are evidence of this.

  14. Hopefully once fusion comes on line a better solution is either flywheels supported by magnetic bearings in a vacuum bottle (in pairs with opposite rotation) for vehicles or a low pollution liquid fuel cycle that operates at a net zero CO2 output. For electric vehicles one possible solution to the range issue might be an induction pickup on the underside that picks up power from a grid or wires in the roadway. You have a system that reports your energy usage at the end of the month and you get a bill.

  18. I want to put a few things into perspective. In 2018 Italy had a mortality rate of about 1100 per day. This was from all causes. On Sunday Italy suffered 700+ deaths related to Covid-19. It may actually have been higher if people died in the homes and were not known at the time (they soon will be). I wonder how many total deaths occurred in Italy that day. I'm assuming that the total number of deaths on Sunday was higher than normal but how much higher. And how many of those deaths were amongst individuals who were at risk due to other medical conditions. I would assume other causes of death are lower. Fatal accidents should be down as an example. Don't misunderstand I am not down playing the Covid-19 crisis. This is serious. In my mind the real crisis here has several factors. One is the fact that the health care systems got caught flatfooted to a degree. Part of this budgets. Another part is just what level of crisis do you prepare for. The second is the varying response of governments. From China's cover-up to disbelief on the part of some governments. Some of this comes from the attitude or belief that "things like this don't happen anymore". Well they can and do. The third factor is the attitude that I am invulnerable. That I'm not going to get sick. In the future I think there are several things I think we will see. Governments building stockpiles of protective gear above what they have now. If we see food shortages governments will also be building up food stockpiles. This is something I also think more people will do. One thing the Italians have shown that will happen in the future is the items needed for ventilators are being 3D printed. As 3D printing gets faster it will allow the production of these types of devices to have that production supplemented (until you get to the Star Trek level of technology 3D printing is not going to compete in mass production imo). Another thing that may come out of this is in the West we already see more people wearing masks out in public. This is something you previously only saw in hospitals and occasionally on planes. In Asian countries this has been common for years. Does it help? It probably doesnt hurt. Ultimately viral threats will be able to be dealt with faster as we learn to take the virus apart to find out weaknesses in its structure and how to attack it by tailoring vaccines. This unfortunately also opens the door to really nasty weaponized viruses. Another thing to think about. I seriously doubt that this is going to get to Black Death levels of mortality. Or the Justinian Plauge. Or when Measles first hit the Roman Empire in the 3rd Century. But let's say 1% of the population dies. In the US alone that's 3.5 million people. China and India it could be 10 million each. And if it gets bad certain areas will get hurt worse. One place I can think of is the Inner Cities of the US. Another is Third World countries whose health care systems are not as robust. Oh, one more thing. If you are infected with this and still go out in public infecting others. SOME OF THOSE PEOPLE MAY DIE. AND IF THEY DO YOU ARE IMO GUILTY OF RECKLESS HOMICIDE AT LEAST.

  19. Any future orbital facility should be designed to have a rotating component. The main reason is we have a data base on 1g and Zero G. We have no idea on the effects of 1/6th or 1/3rd G on the human body. I have to think there are some but if it is graphed out is a straight line? A curve that starts shallow and rises rapidly as the G increases*. Or is it a curve that rises rapidly and then flattens out? In reality we could have done this anytime in the last 40 years if we really wanted to. There have to major benefits from using spin "gravity" even if a fairly low acceleration is acceptable simply from the housekeeping and sanitary side of things.

  20. It's pretty common for machinists to squirrel away the odd pieces metal. The reason is they will use it for what are termed "government jobs". As in "by the people and for the people". The jobs that one might squeeze in for ones self

  21.  @TheOleHermit  So I had it reversed. The point is technology has made it possible for idiots to show their idiocy to the world. The most dangerous thing in the world today is somebody who live streams something with no context as to what is actually going on.

  22. I remember during the CF hype there were academics claimng that cheap Cold Fusion would be one of the worst things in the world as it would actually make it possible to raise living standards world wide

  23. Someday, someone will go to Mars and other places in the Solar System. But I don't think anyone should go until several things happen. The first is travel times have to come down to 60 days maximum. Second is some form of magnetic shielding needs to be developed to help protect crew and passengers. Third is more advanced pressure suits. The best option here IMO is the Mechanical Counterpressure Suit. Or the Space Activity Suit as some call it. These should allow a far greater degree of mobility and dexterity for the user. Fourth is some sort of reliable and safe nuclear power unit. This is pretty much a given for the faster trip times mentioned in #1. Fifth is a source of propellant that can be obtained at Mars. The best source for this may actually be the Martian moons. Sixth is a Mars SSTO (Single Stage To Orbit) re-usable lander. And #7. Ships designed to provide spin gravity. This would allow mission personnel to adapt to 1/3rd gee on the trip out. On the return trip the spin rate could gradually be increased to 1 gee to adapt the crew to returning to Earths gravity. This would also negate the effects of prolonged weightlessness. Why there hasn't been research into spin gravity in the past is beyond me. It almost seems as if NASA is fixated on zero gee. One way to make ships with spin gravity is through the use of tethers

  24. Once we have a decent industrial capacity off of the Earth we could be able to construct really big telescopes with mirrors that will dwarf the proposed ones. These could possily be a side benefit of the production of Solar Power Satellites that use a large thin mirror to concentrate sunlight either onto advanced solar cells or the heat exchanger of a thermal type of generator. Of course some in the science community and the general public will complain about destroying pristine examples of the early Solar System or "polluting" space. Yah right. Pristine examples of the early Solar System that have been blasted by impacts. A major impact on an asteroid distributes more "pollution" into the Solar System than most people could imagine.

  28. Its not just about mpg. It's also about operating cost. Lets say a 777 is burning 5 gallons/20 liters per mile. Let's say you have a 777 carrying 240 people. It would take 40 of these to have the same capacity. Just what is the fuel usage per passenger mile. Ask your self this. If a 6 passenger minivan is getting 25mpg on the highway with a full load of passengers and a Honda Fit with 2 or 1 person on board is getting 50 mpg which vehicle is getting more passenger miles per gallon. This may have a future in the business aircraft market. But I have heard that before. Anyone remember the Beech Starship. Much less the LearFan? https://www.google.com/url?sa=t&source=web&rct=j&url=https://en.m.wikipedia.org/wiki/LearAvia_Lear_Fan&ved=2ahUKEwir58_Hv8LtAhUiAp0JHTmDD-oQmhMwDXoECAoQAg&usg=AOvVaw0dAMjsNg802qU_-FQYVRyA
