Are automobiles a major cause of global warming?

    True, but I would not call 39.2 degrees F very close to freezing.

    I am no scientist but fire and water have always been very mysterious and fascinating to me. Almost like magic in their properties. I don't think that even the top scientists fully understand them.

    It is a good thing that ice becomes less dense and ice cubes and ice bergs. I hate to think what would happen if all the floating sea ice suddenly sank to the bottom.

    It probably can be done, but I have no idea how you could destroy water. You can change it from a liquid to a gas or to a solid, but it is still there.

    If you ever find yourself in danger from a forest fire, do not try to run uphill to escape. Fire is one of the few things that travels faster uphill than downhill.

    Well, if one were to believe David Suzuki and his followers, just using it to frack, effectively destroys the water. For life so they claim.

    That's another guy that (seems to) have an agenda. I wish he would stick to wildlife nature features...but then even when he does those now, he weaves the man-is-all-things-responsible angle into it..

    Just found this posted on Facebook. It seems to be an Elon Musk venture. Or at least he is involved. May be the answer to the horrible High Speed Rail that have eluded US so far.


    ET3 is literally "Space Travel on Earth". ET3 is silent, low cost, safe, faster than jets, and is electric.

    Car sized passenger capsules travel in 1.5m (5') diameter tubes on frictionless maglev. Air is permanently removed from the two-way tubes that are built along a travel route. Airlocks at stations allow transfer of capsules without admitting air. Linear electric motors accelerate the capsules, which then coast through the vacuum for the remainder of the trip using no additional power. Most of the energy is regenerated as the capsules slow down. ET3 can provide 50 times more transportation per kWh than electric cars or trains.

    I have been aware of this for some time. I thought it worked like the vacuum tubes you use at the bank but apparently that is not the case. An electric power source powers you up to speed in a vacuum tube (just like space flight) and you coast to your destination.

    Easier and cheaper to build, like 1/20th the cost of high speed rail, and much more efficient. I think it will work.

    My brother's microwave died not long ago. He took it apart - there's some fun donut magnets in those things. Had a good time showing off and levitating plate and stuff for his grandkids. The California light rail project is maglev but this project of Musk's would handle the air friction part.

    I don't think the CA High speed rail was going to be MagLev. Just high speed rail like they have in several places including China. The CA/NV is supposed to be Maglev. Not sure it has gotten off the ground with the recession. I think Harry spent the money on the airport.

    MAGLev is history for CA.

    SOUTHERN CALIFORNIA: Maglev gone, but high-speed rail remains
    Regional transportation planners focus funding, planning on local connections, not bullet train to Nevada

    But the idea of a magnetic levitation train didn’t stick around for long in regional transportation plans developed by the Southern California Association of Governments. Local planners instead are concentrating on connections within Southern California, so that when — and if — bullet trains ever come, conventional trains have a steady and direct route to get to them.

    So 11 years after maglev made its debut in the regional transportation plan for Southern California, the agency overseeing the road and transit plan has deleted most of the Anaheim-to-Vegas route once proposed, saying maglev is not moving forward and is falling behind a competing project. As a result, the 2012 transportation plan under consideration by the Southern California Association of Governments does not include the $12.1 billion California-Nevada Super-Speed Train. - ia-maglev-gone-but-high-speed-rail-remains.ece

    Hopefully they are both gone FOREVER.

    Thanks, just flashed on an old link I guess. Sounds like the Shanghai one is just a "demonstration" one.

    Folks somehow think high speed rail actually would solve something. Without the built in population density and local transportation of Europe, it's a guaranteed black hole for all our non-existent $$.

    They just celebrated the 30th anniversary of the local transportation network (DART, Dallas Area Rapid Transit). Guess how much of the DART budget is paid by actual fares (i.e., the users).....12%! Ridership has been HALF of projections, and isn't getting any better. I bet the same would happen with a high speed rail network.
  • gagricegagrice San DiegoPosts: 28,680
    San Diego has a nice Trolley system. The ridership does not even come close to paying the bills. Looking at their annual budget, the riders paid about $94 million. State subsidy was $137 million and they are still showing $112 million shortfall. Time for the riders to kick in a little more I would say. Srs can ride all the want for $18 per month.

    Going Green should be a shared proposition. Not just a burden on the tax payers. A student can ride the buses and trolley cheaper than the school bus fees.

    That's kind of apples to oranges though. Transit isn't self-sufficient anywhere. Where do you think money is used from high gas and other taxes in Europe? It subsidizes transit. Instead of aiding ungrateful pseudo-nations and propping up the military-industrial and praetorian classes, they put money into infrastructure which is a common good. Different priorities.

    Farmers Almanac is saying that we are in for a bitterly cold Winter. All the hot air must be trapped in the D.C. area while the GW alarmists are wringing their hands.

    I have to agree, twenty or thirty years ago David Suzuki used to have some interesting information, it seems that now he is all about the evil deeds of humankind.
  • gagricegagrice San DiegoPosts: 28,680
    Both Northern and Southern Hemisphere hit with record cold temps.

    Most notably, Bettles recorded a low of 15ºF Saturday morning. This is by far the lowest temperature of record at Bettles in August. The previous record at the Bettles in August was 22ºF on August 30, 1969. At old Bettles, about four miles downriver from the current townsite, a low of 20ºF was measured on August 24, 1948.

    Hundreds of families have been affected and more than 250,000 alpacas have died due to freezing temperatures and snow storms.

    The global warming cult, rather than admit they were wrong, changed their mantra from global warming to climate change. They can't miss with that name as the climate has been changing for billions of years.

    Even I would agree that the climate is changing, so I guess with the name change they can no longer call me a denier.

    It is kind of satisfying however, that all of us ignorant global warming deniers forced them to give up on global warming, change the name to climate change, and tacitly admit they were wrong.

    Some of the GW cult are still spewing CO2 from their mouths and Gulfstream Jets. Real examples of do what I say not as I do.

    NASA says it's getting hotter. So why is the Arctic ice cap growing so fast this year? (Washington Post and Daily Mail)
  • gagricegagrice San DiegoPosts: 28,680
    Because the Scientists don't know anything. And are afraid to say anything that goes against the political agenda. I got news for the Politicians pushing their GW Scam it has backfired in Australia. And the Labor party and Green party just got their butts kicked at the polls. High electric costs a result of carbon tax was the one big incentive. We are getting totally screwed in CA as a result of the GW Scam. Unfortunately the Welfare vote will keep the dregs in office. elf-to-the-service-of-this-country-20130907-2td1g.html
  • gagricegagrice San DiegoPosts: 28,680
    The important question is this? Are the American electorate as smart as the Australians? Will they equate higher energy cost with government mandates, and vote out the perpetrators of those GW taxes & executive orders? In a nation of Sheep it is unlikely. I am still waiting for a LOGICAL explanation of how CO2 can cause global warming and cooling at the same time.

    The way I see our scientific community is a bunch of followers. If a prominent scientist says it is GW all the underlings agree with him. Look at any University and you will see how that works. They are just as political as our government. Maybe even worse. Integrity is for sale to the highest bidder.

    Yes the Arctic Ice is refreezing at a record pace, and the Antarctic ice is at record levels. But that won't deter our brilliant GW adherents from their war on fossil fuels and by extension their war on our lousy economy. They will continue to look down upon the ignorant unwashed peasants like myself who cannot understand why Global Warming causes the Earth to cool.

    Only exceptionally intelligent people like Al Gore and Nancy Pelosi have the ability to understand that concept.
