    Cool.. I thought the numbers would work out to something like that. I'm just a mining engineer, so the exact power conversion is beyond my calculation ability.

    But if you want some coal to add to your engine... I can dig you some. Last I heard, Alberta had 100 yrs of reserves for Canada's use just using today's technology.

  4. Coal powered car? on Nucular Hydrogen Economy · · Score: 4, Insightful

    Coal makes up most of the USA's electric generating capacity. If you want a hydrogen powered car that uses "electricity cracked water", then what you have is (largely) a coal powered car.

    However, if you use hydrogen from "steam cracking" of natural gas (CH3), then you have a natural gas powered car.

    Nobody said the hydrogen was free!

  5. Where do you think H2 comes from? on Nucular Hydrogen Economy · · Score: 5, Interesting

    I'm aware of two economic methods of generating H2. The least economic is from cracking water using electricity (the topic of this article). The most economic is by cracking natural gas - this is the method used by everybody I know of in the chemical industry.

    Natural gas, mostly methane (CH3) is reacted with steam (H2O) such that CH3 + 2H2O = CO2 + 3.5H2

    So, when somebody says he wants a hydrogen powered vehicle, what he really means is he wants a natural gas powered vehicle.

    Not all diamonds are expensive. Only the 'gem' quality ones will set you back the price of a water-cooled Athlon system. Gems constitute roughly 10% of a diamond orebody; the rest are classified as 'industrial' diamonds and sold much cheaper to people like Boart-Longear for use in mining drills.

  13. Why go to space? Survival. on Benford on Space Exploration · · Score: 1

    Yes, it is a sad event when people die. All forms of transport
    involve risk but space flight is very spectacular when it goes
    wrong. Seven people died in the shuttle and the entire world
    knows about it. Seven people died the same day in an avalanche
    in western Canada that swept over a group of teenage skiers from
    south of Calgary. A crowded passenger train collided with a
    freight train in northwestern Zimbabwe... 42 people were killed
    and another 60 injured. Transportation of any form involves
    risk and people will continue to die in train, car, airplane,
    and spacecraft mishaps. Society will not stop moving people
    about in spite of the risk, therefore it makes sense to take all
    reasonable precautions and then "just do it". The question the
    American taxpayers need to ask is are shuttles the best way of
    moving people and cargo to orbit?

    The shuttles are 1970's technology. My palm pilot has more
    memory than the shuttle's main computers (they were designed
    about 5 years before the Apple //+, remember it?). Computers
    are easy to upgrade, but what about the structure of the
    vehicle? The airframes of the shuttles undergo much harsher
    treatment than your typical military jet... airframe fatigue
    caused Canada has retired 25% of the CF-18s they bought in the
    early 1980's. Columbia was planned for retirement sometime
    after 2010 making it a rather geriatric craft.

    Aside: Canada can be proud that our Sea King helicopters may
    still be operating in 2010 and thus continue to hold the 'old
    age award' for military aircraft. There is still no sign that
    the federal government is going to award the replacement
    contract for these choppers.

    The US shuttles are old and still serviceable but they are risky
    to run. The old Soviet method of launching 'Soyuz' module is
    arguably more expensive, but you don't worry about fatigue (each
    module is used once and discarded). The Soyuz sit on top of an
    industrial launch vehicle (the Proton rocket) that has one of
    the best launch records in the world. The Protons are 1960s
    design, but each is, again, built brand new for each launch.
    The vehicles wear out but the design doesn't. Nasa abandoned
    the disposable launcher concept when they moved into shuttles
    and now the US space program is completely dependent upon the
    shuttles for moving humans back and forth from space. Nasa will
    likely ground the shuttle fleet until the investigations are
    done, so the Russians and the Soyuz vehicles are the only
    passage back and forth to the ISS. Now ask the question: who
    has the better design? The Chinese are in the process of
    building a manned space program -- their manned module looks
    more like a Soyuz capsule than anything in the US inventory.

    So why is the loss of a US space shuttle important? Because
    space flight is vital to the survival of our species. Humans
    are vulnerable to extinction so long as we are bottled up on
    this one planet. Any of a number of events can kill us off: a
    large asteroid impact, instability in our Sun, or local cosmic
    radiation bursts. Items one and two would not spell the end of
    our species if humans had a sustainable society operating, for
    example, in the asteroid belt. The shuttle has focused people's
    attention on the dangers of space flight and may result in even
    more conservative designs in US space vehicles to mitigate the
    danger. The cost of this diminished return for safety will be
    delay and fewer missions flown. Fewer missions means it will
    take longer to achieve the interplanetary 'sustainable society'
    that will protect humanity from disaster.

    And that would be the biggest disaster of all. Humans need to
    break free of the Earth and our species is at risk until we do.
    Individual people will be at risk during the journey. People
    will continue to die in space the same as they die on motorways
    and in railroad mishaps. Don't think for a moment that the
    journey into space is not worth the risk. It is the only way to
    ensure our survival.

  16. Materials and the gravity well on NASA Consider "Demanning" Space Station · · Score: 1

    Anything you wanna send to space has to be lifted into orbit; the 'gravity well'. That means anything that has mass, like $100/tonne structural steel, needs to be lifted at an outrageous cost ($1000's per kg).

    How to mitigate? Well, one way might be to build space structures without structures by planting them on top of something. What kind of something? How about an asteroid; send a robot solar sail to the Asteroid belt to fetch a small one (250m is good enough) then jockey it into orbit from above. Then you can just lift stuff like solar panels and radio transmitters from Earth and spread them out over the rock. Less structural bits == more electronic bits with flashing lights.

  21. Real life arsenic treatment on Mining Metals Using Plants and Trees? · · Score: 1

    I'm a mining consultant and have worked around Arsenic containing effuents in the past. Typical way to 'treat' arsenic is to fix it into a stable, non water soluble form. We typically use ferric sulphate to treat effuents containing arsenic, resulting in a 'reasonably' stable arsenic ferrosulpate sludge. This you can dump soil on and plant trees as the arsenic is not likely to spontaneously jump out of the solid into solution.

    Another more brute force way of doing the same thing is using a high-pressure autoclave to achieve the same result. Not naming names, but there is a mine located inside the city limits of a Canadian provincial/territorial capital that uses an autoclave the fix arsenic from both a solid trioxide form and a mineral arsenopyrite form. The device works so well that the federal gov't has considered asking this mine to assist cleanup of a neighbouring arsenic contaminated site.

    The use of bioreator tanks for sulphide leaching is practised in Africa. I don't think they accept arsenic in the plant feeds, but it is only a matter of time before they find the right thermophile bugs to fix arsenic, then there will be another industrial route for getting the stuff into the tailings pond where it belongs!
