  1. "We're not talking about that kind of intelligence" There is no scientific evidence, or philosophical argument that consciousness is a kind of intelligence. The ideas are separable. Alexa is rather intelligent, but nobody is talking about her civil rights. And on the other end C.S. Lewis said "I am angry when you kick my dog, not because I think he is intelligent, but because I think he is conscious."

  2.  @CarFreeSegnitz  "The whole point of going into space is to experience microgravity." That may be a major driver of space tourism, but space tourism is just a stepping stone on the way to space colonization.

  3. "low gravity, it turns out, is deadly to humans." There have been no experiments on the long term exposure of humans to LOW gravity, unless by LOW you mean essentially NONE as in the ISS. The cheapest way to test exposure to gravity BETWEEN ZERO AND ONE would be with a station providing spin gravity.

  4. Tell that to the Venezuelans. They had a profitable oil industry till it got nationalized, now they are starving and the oil industry is in the red. A private power plant has to undersell the competition. A government power plant can outlaw the competition (say on "environmental" grounds) and be as inefficient as they like.

  5. +JackDespero "Those private companies are not going to do anything with that, they are only gathering money and spending it in things that have been done already. The latest publications of the MIT endevour are things that have been done in other machines of the same since in the 1990s. Just give more money to fusion and you will see a huge speed up." This is the exact opposite of the way the world works. The private companies are, as always, investing because they hope to make money from the finished product at the other end. They are in other words TRYING TO SUCCEED (though there is no guarantee they will). Those running the government programs have no such incentive, and get their best job security by CONTINUING THE PROGRAM (these are guaranteed NOT to succeed). If you have money that wants fusion, as opposed to fusion research, invest in the private programs (or pick one) if you can.

  6.  @user-rt8sh7xt1d  It's been state run for some time and we're not getting anywhere. The way forward is profit. One thing holding the process back is a government thing, the legal notion that space resources are the "common heritage of mankind". Unless the prospector can OWN it he has no incentive to GET it. This needs to change for the sake of human progress and survival.

  7. It would depend on HOW FAR the run was. Higher gravity would give you better traction and leverage for acceleration from a start. But under 1G, fatigue tends to be an ever increasing factor as the length of the run increases, thus the faster runs would occur in lower acceleration environments. Also, you would encounter diminishing beyond a certain point with both high G sprints and low G marathons. You can't run if you can't stand up, and you can't run if your feet don't stay close enough to the ground.

  10. We got the first model Enigma from Polish infiltrators, a subsequent model was captured, but that was not enough. To decipher an Enigma message you needed a machine, AND THE KEY sequence, which was periodically changed. (This is similar to modern DES encryption which requires the algorithm and the key to read.) Turing and his team developed a method to use the computer to do a partial-known-text brute force attack to find the key fast enough to get useful intelligence each time the Germans changed the key. Because British Intelligence got the machines, we did not have to DEDUCE THE ALGORITHM AND CRACK THE KEY AT THE SAME TIME, which would probably have been impossible with the tools at hand.

  11. "Common heritage" is tantamount to throwing the resources of the universe away. Nobody will extract resources if they don't get to keep them when they do. The current state of the law is in NOBODY'S interest. We need some sort of "homestead law" whereby those who propose to extract resources can obtain clear title to use/sell them. "Common ownership" of resources has traditionally led to starvation.

  12. Folks, this so easy to search, why are you all blowing smoke? Deuterium, (Hydrogen isotope 2) the easiest atom to fuse, constitutes just over one out of every ten thousand Hydrogen atoms in ordinary water. It has an ENORMOUSLY LONG half life and heavy water (D2O) is SAFE TO DRINK. The fusion of two Deuterons produces either a Helium -3 nucleus, (which is also considered so stable they won't list a half-life) and an fast neutron; or a Tritium nucleus (Hydrogen isotope 3) which has just over a 12 year half life and beta decays to Helium 3 and a fast proton. The most dangerous radiation from this process is not the nucleus products, but the NEUTRONS released by the process directly. A more energetic reaction is to fuse 1 Deuterium and 1 Helium-3, producing 1 Protium (Hydrogen isotope 1), and 1 Helium-4 (the common stable isotope pumped into airships and toy balloons) This releases more energy per unit of fuel, and is aneutronic (doesn't generate neutrons to make the reactor radioactive), but it requires much higher energy of fusion, so it is harder to ignite. Also, we do not currently have a supply of Helium-3 in industrial quantities. We could get it from Dee (Deuterium) reactors, but we would have to put up with the neutrons from that reactor. Rather than messing with that, SECOND GENERATION D/Helium-3 reactors may opt to import the Helium-3 from the Moon, it's lighter than garden variety helium (cheaper to transport and stable) and fused with Terrestrial Dee can release a LOT of clean energy. This high energy for low fuel input characteristic (along with the aneutronic property) might also make it the power plant of choice for large spacecraft.

  20. I'm not a hydrogen advocate, but since they convert power more efficiently overall, fuel cells would probably add less water vapor for a given power output than internal combustion engines (ICEs produce many emissions in small quantities, but the two main products are water vapor and carbon dioxide)

  21. "Getting people to buy more stuff to make things better is old and never worked." That is precisely what has driven technological progress so far. Depending more and more totally on government for all our needs is locking ourselves into a box WE WILL NOT BE ALLOWED OUT OF.

  22. Current home charge units need a garage (except for the 120v trickle chargers). Most car owners don't have a garage. Many apartment renters don't have access to an outlet near their parking place, and unless they're separately billed for their electric, the landlords won't let them plug into the lobby to charge.

  23.  @user-rt8sh7xt1d  "We would have gotten somewhere if the nations of the world would cooperate." And if pigs had wings, they could fly. "being a wage slave in space doesent sound too nice." You have a choice, so it's not slavery. It's not like anybody is forcing you to go. It's not like anybody even invited you. Stay home, or not. Or hold your breath until governments start acting in humanity's best interest. " It is because the leaders of our society has nothing to gain by doing something like this" And, for them, they're right. They have theirs. They look at every person or dollar spent outside their jurisdiction as one less that they can control. If governments were to drive the development and settlement of space, they would only mess it up.

  24.  @TonecrafteLuthiery  "I obviously can't speak to that in sweeping generalities" Then proceeds to speak in sweeping generalities, misleading and false in several particulars. FDR is broadly understood by economists to have parlayed what ought to have been a fairly ordinary recession into the nearly decade long Great Depression by very bad economic policies. Reagan turned simultaneous double digit inflation and double digit unemployment around in his first term. The housing market debacle was a result of government policies forcing lending institutions to make bad loans, and the regulatory institution guaranteeing the loans. Bush criticized this policy, but Democrats in congress rushed to the defense of the director of the agency, characterizing Bush's criticism of the head and the policy as racist. You forgot to say what was so wonderful about an open borders immigration policy. "Though I won't pretend that the left is never targetted by fake news, in the modern age, fake news is a phenomenon that predominantly effects the American right."[sic] That statement says almost the opposite of what you intended to say. The "target" of fake news is the person or fact misrepresented by it. And the person or position effected by it is that target. You seemed to have told the truth by accident: 0. During the Vietnam war, Dan Rather passes off his collegue in soldier drag, a young Eric Sevaried, torching a hut in Vietnam as a candid news shot of a military operation. 1.

(ABC News) In 2009, ABC News Blatantly Lied About The 1 Million Protesters in Attendance, Reports 60,000 This is a bad one because it was so brazenly false. Glenn Beck’s 9-12 March on Washington DC brought in over a million Tea Party protesters to call for lower taxes and less federal spending. Clear pictures of the crowds from the tops of Washington DC buildings can be cross-referenced with the USA Today/National Park Service schematic for estimating the turnout at President Obama’s inauguration in January earlier that year. The turnout was undeniably one million plus. 5. (CBS News) 1 Million Disenfranchised Black Voters in The 2000 Election Back then, activists claimed that dogs and hoses were used to keep black voters from the polls. Claims that thousands of blacks were disenfranchised, harassed, and intimidated from voting ran rampant. The U.S. Commission on Civil Rights conducted a six-month investigation of the charges and found absolutely no evidence of systematic disenfranchisement of black voters. The civil-rights division of the Department of Justice also found no credible evidence that any Floridians were intentionally denied the right to vote. 6. (CNN, CBS News, NBC, et al.) TV Networks Call Critical Toss-Up Race in Florida for Al Gore Too Early In a historically very tight toss-up race in a state with critical electoral votes, the mainstream media’s television networks called Florida too soon for Al Gore in an “embarrassment of major proportions.” Dan Rather was so bold as to make it a guarantee, “If we say somebody’s carried the state, you can take that to the bank. Book it!” The networks made the call just before 8pm Eastern and were forced to retract their call. By 1:30am the Sunshine State was still too close to call. The earlier pronouncement may have had the effect of chilling votes on either or both sides. The state was eventually carried by George W. Bush. 7.

(The Guardian) UK Newspaper Publishes Chain Email Hoax Claiming President Bush Has The Lowest IQ of Any President In 2001 after the election of President George W. Bush, a hoax email began circulating claiming that a study of presidential IQs by the Lovenstein Institute of Scranton, Pennsylvania found that George W. Bush had an IQ of 91, the lowest of any US president, while outgoing President Bill Clinton had the highest at 182. The study was a fabrication and the Lovenstein Institute doesn’t even exist. Neither do the sociologists quoted in the email. But in a stunning display of the journalistic standards at The Guardian, the fairly obvious chain email hoax was published as news! The paper retracted the story when the Associated Press pointed out their error. 15.

(NBC) Nightly News Anchor Brian Williams Lied About an Iraq War Helicopter Incident In 2003 Dateline NBC headlined a story, “Target Iraq: Helicopter NBC’s Brian Williams Was Riding In Comes Under Fire.” In a 2007 retelling of the story, Williams said, “I looked down the tube of an RPG that had been fired at us, and it hit the chopper in front of us.” By 2013, Williams said, the helicopter he was in had been “hit … and landed very quickly.” In February of 2015, Williams had to recant the story after criticism from the Chinook crew who said the helicopter Williams was riding in was not hit by an RPG and that he could not have seen the one that was hit ahead of the one he was riding in because it was a half hour ahead of his flight. Further scrutiny prompted by this revelation found that Williams had told inconsistent stories about a man committing suicide in the New Orleans Super Dome during Katrina, falsely claimed he was at the Brandenburg Gate the night the Berlin Wall came down, and lied about flying into Baghdad with SEAL Team Six. 17. (The Associated Press, Boston Globe, CNN, Fox News) FBI Criticizes Media for False Reports Regarding The Boston Marathon Bombers In the aftermath of the Boston Marathon Bombings in 2013, with the perpetrators still at large, several news sources falsely reported that an arrest had been made. 18. (The Washington Post, MSNBC, ABC, NBC, CBS, et al.) Media Spreads Inflammatory Fake News Story About a Police Shooting in Ferguson, MO In 2014, when a Ferguson, Missouri Police Officer confronted a suspect who matched the description of an assault and robbery that had just taken place at a convenient store, the young man, 18 year old Michael Brown, fought with the Police Officer, Darren Wilson, struggling to wrest his gun away. When Wilson pursued him on foot, Brown turned and charged at him, and Wilson fired several shots into the front of Brown’s body, killing him. This was a very delicate tragedy with strong racial overtones, and in a rush to support a racially-charged, inflammatory media narrative, journalists enthusiastically spread a fake news story: that Michael Brown had his hands up and yelled “Don’t shoot!” at the time Wilson fatally discharged his firearm. It turned out to be false. Upon investigation by the Federal Justice Department, eyewitnesses changed their stories or admitted they didn’t see the shooting take place. The eager embrace of this narrative by the media had real world consequences, stoking tensions and anger in Ferguson and leading to looting of local businesses and protests that turned violent. The shooting happened in August 2014. By March 2015, MSNBC anchor and Washington Post columnist Jonathan Capehart finally offered a mea culpa with a column entitled, “‘Hands Up, Don’t Shoot’ Was Based on a Lie.” 19. (The Daily Mirror) Piers Morgan Fired From UK Newspaper for Hoaxing Photos of Iraqi Prisoner Abuse 20. It was a story that literally blew up in NBC’s face. On Nov. 17, Dateline NBC aired a report titled ”Waiting to Explode?” questioning the safety of some General Motors trucks. To try to ensure dramatic footage, the show’s producers allowed incendiary devices to be strapped to trucks for a crash-test demonstration. When GM discovered the setup, the carmaker sued NBC for defamation and temporarily removed its ads from the network’s news programs.

  25. +Ratatoskr Folks, we want abundant cheap energy from fusion, we will never get this from a government utility, especially an international government utility. The administrative overhead and red tape will proliferate to eat any savings from the new tech. Also the additional centralization of power will be detrimental to freedom. All a company can own is a design, and it will only be a monopoly till other companies come up with a competing design. And none of them (even the first one) have a market unless they undersell current utilities (unless the government distorts the market, say for environmental reasons to favor fusion).

  26. 2) Of course, the devil is in the details, and I don't know the details of the hardware, and I'm not an H hybrid fan, but I can think of 2 reasons why they would be better in the cold: a. The cold slightly reduces the temp/pressure problem with the fuel tank. b. The fuel cell produces heat for the heater at no additional electricity cost (just like an ICE) (and steam for your coffee/tea maker, to boot.)

  32.  @southrnlyfe  According to the figures cited in the video, ICEs are 1/3 as efficient at converting the chemical energy in fuel to useful work as fuel cells. Hydrocarbons have more molecules of hydrogen in them than molecules of carbon and both the carbon and the hydrogen combine with the oxygen from the air intake to produce CO2 and H2O, respectively. Hydrogen has a higher energy density per exhaust molecule than gasoline. Reasoning from these inequalities, yes, I am sure that ICEs produce more water vapor for a given power output than hydrogen fuel cells. Don't get me wrong, I am a gasoline man myself (might as well be for the next 5 years anyway, I don't borrow to buy new cars, I pay cash for used ones.)

  36. As with several good algorithms, knowing the wiring (algorithm) without knowing the key, does not enable you automatically to read the messages. Turing used the computer hardware for a partly-known plaintext attack that could brute force the key fast enough to recover the ability to read the messages quickly when the Germans changed the key. The Polish contribution was necessary, but insufficient, to generate practical intelligence from the coded intercepts.

  38. It should be adding less water vapor to the atmosphere than internal combustion engines do per mile because of the greater efficiency of the fuel cells (ICEs emit some other stuff in small quantities, but the 2 biggest emissions are CO2 and H2O).
    1
  39. "Is it really just that much less efficient to burn it rather than convert it to electricity?" He showed a 40 some odd percent efficiency for the fuel cell/ electric motor, and a 15% efficiency for an internal combustion engine. I don't suppose those figures will change much just because you're using hydrogen rather than gasoline/petrol. In some regions you aren't even saving money per mile on EVs, because of the price of electricity. It will be a long time before you break even on miles per dollar even with fuel cells, given its lesser efficiency compared to EVs. With a third of the efficiency for ICEs as FCs don't hold your breath.

What do you think men of goodwill have been trying to do for all of recorded history? We didn't stop expansion and economic development, and if we had we would be in a lot worse shape than we are; which is, on the whole the best we've ever been materially with more people lifted out of poverty than ever before. If we don't use the window of opportunity to access extraterrestrial resources, eventually it will all come crashing down, never to return. Starvation, ignorance, grinding poverty, your Luddite boot on the hopes of man till kingdom come.

  44. More like a slight extension of range in practical terms, but I always thought this was a good idea. It would be trickle charging while you shop without having to find or use a plug. The area of solar cells you could put on a car wouldn't produce enough juice to keep you going even at stop-and-go city speeds, much less highway speeds. But the juice it does add over the range of all but the shortest trips is well worth the added weight of having them. And the small amount of juice you get from the panels during the trip are more efficient than the same amount of juice from panels at home charging your EV, because they are going straight to the motor instead of losing from the charge/discharge cycle. The reasons why this has not been adopted are: 1. Cost. The EV is expensive already. The photovoltaic panels are expensive. Together they are REAL expensive. 2. You would have to toughen the PVs. The current ones are not rated for the sort of beating they would get on the outside of a car. I saw a YT vid about a do-it-yourselfer who had converted a VW van to a solar/electric RV (with deep cycle lead acid batteries). It didn't have the range of a Tesla (because of the cheap batteries), but he could park it at a camping place and charge the batteries from the PVs, or faster from an outlet. This link is not the one I saw before, I think, this is another but the solar part is layed out almost the same way. Near the end of the vids both guys talk about a future upgrade with lithium batteries: https://www.youtube.com/watch?v=fGZ1zbqAGA0

  45. Why settle for 1/3 the efficiency? And a gazillion more moving parts.

  46. 2 person cars are a solution for town driving, but for driving on the highway, small subcompacts tend to be LESS efficient on the highway than a smallish 4-door sedan, because it is harder to make them conform to the aerodynamically ideal teardrop shape. Aerodynamics are also the main reason why "motorcycles are not any where near the efficiency that a Honda Civic or Honda City gives in terms of its weight to fuel efficiency ratio", not motor efficiency. Weight is the dominant factor in city driving (accelerating and decelerating mass), but on the highway it's all about aerodynamics. When you are considering just the efficiency of motorcycle engines, there is the fact that they are usually air cooled, and spend much less of their use cycle operating at the ideal temperature than a water cooled engine, which, due to the thermostat, turns off the cooling system when not needed.
