  1. Hmmm on Comet Probes Given New Duties · · Score: 0

    The summary doesn't make this clear, but the 'revisit' to Tempel 1 (nor the other additional tasks) does not involve establishing orbit; according to TFA it will be a flyby. Thus the Dawn mission - if it achieves it's objectives - will still be the "first spacecraft to enter into orbit around two different planetary bodies other than the Earth and Moon" (from the Wikipedia article).

    Incidentally, Dawn was scheduled for launch at 1609 EDT (2009 GMT) on 7th July 2007, but has now been delayed by approximately 24 hours, to 1604-1633 EDT (2004-2033 GMT) on 8th July 2007.

  2. Re:Somewhat offtopic but on New Fuel Cell Twice As Efficient As Generators · · Score: 0

    True, I'm sure it's a tiny proportion, but my posting wasn't to make a point against nuclear per se or to imply that it was pollutive because of needing concrete, but was an observation that it - or, as I was corrected on, anything requiring significant structural construction - isn't as "carbon free" as you might think. Was just a bit of information for those who may not have known. It got modded down anyway, so apparently you all knew ;)

    And again apologies for the offtopic.

  3. Somewhat offtopic but on New Fuel Cell Twice As Efficient As Generators · · Score: 0
    Nuclear power IS carbon intensive.

    Consider how much concrete needs to be made during the commissioning of a nuclear power station.
    From this page:

    Concrete is responsible for 7-10% of CO2 emissions worldwide, making it the biggest climate change culprit outside of transportation and electricity-generation.
  4. Ah good on A New Global Memory Card Standard · · Score: 1

    Finally, a standard to make transferring my pictures and multi-media (that's pronounced mul-tie-media, btw) so much easier! ATM I find it so difficult reaching across the desk, plugging my usb-stick in to the front of the PC, and putting files on it. Plus I have to carry all that extra weight around with me. How will this one work then? Mind-reading device that actually stores the stuff in your head?

  5. Re:Ammonia (products) on Driving on Starch · · Score: 1

    IANAC, but from a high-school chemistry video about the Haber Process, which is the most efficient method of ammonia production to date (or most economically viable) I seem to recall that production of ammonia requires a substantial amount of natural gas for use in the reaction. Infact I can remember a pipeline running into the plant that was about the width of my bedroom. That's a lot of natural gas. So, unless ammonia were surprisingly more energy-dense than other substances mentioned/proposed (and more energy can be taken out from it than was put in during production and the use of all that natural gas), I think unless we were to find a large comet which we could capture and mine, we would have to find a substantially more efficient method of producing ammonia first. I could be wrong of course, it's been a while since I was in a chemistry lecture, but I seem to remember the process requiring substantial energy input to obtain the ~500C temperature and 250atm pressure required to run the reactors most efficiently, plus the natural gas input for use in the reaction.

  6. hmm on Scientists Claim Major Leap in Engine Design · · Score: 1

    As I was reading the post, one thought immediately came into my head once I first came across the notion that these efficiency gains focussed on 'fuel delivery', which was "I wonder if it would be possible to use some kind of inkjet-like system to get fuel into the cylinders"... you know what I mean? Peizzo electric turbo ultra macro squirters? Then it occurred to me that stuff still needs to get out of the cylinder ... I guess the aforementioned rotating valve approach would be best still : )

  7. Re:I hope it gets better on The 660 Gallon Brewery Fuel Cell · · Score: 1

    ...Not to mention the strange looks you'd get from the neighbors when a tanker from the brewery shows up every day to top up your barrels. "I'm just doing my bit for global warming!" -x- No/few mentions yet of the 'clean' water this process apparently produces -- clean enough to be fed into the house also, I wonder?

  8. No one makes you watch it, you know on Busting the MythBusters' Yawn Experiment · · Score: 1

    This week on Mythbusters, Horse vs. Donkey: There is a widely known rumor that a donkey can accelerate faster than a horse from the line, so this week Adam and Jamie investigate! Starting out with a series of tests using actual horses and actual donkeys that the kids like to watch and understand, they proceed to test the effect of adding dynamite: will the horse be able to beat the donkey with a stick of dynamite to assist it? Does donkey poo or horse poo travel fastest when propelled by dynamite?
    Finally the duo will conclude with a set of precise, statistically accurate analyses (to only the most suitable numbers of significant figures!!!!11111) intended to appease the exacting standards of Slashdot nerds who cannot otherwise sleep. Additional donkeys and horses will be tested in a similar manner to the first. Hypothesis tests will be run to determine whether it is likely that all donkeys are faster, or if it is just a small portion of donkeys, based on the results of the tests. Tests will be conducted using N-zero-body, Karez-McDamnit and Hausad De Ywannabe methods, and we conclude with our answer neatly written and underlined in red.

    The scary thing is, people would probably watch it. At least until the poo bit was finished.

  9. Re:Least of our worries on Bird Flu Pandemic Could Choke the Net · · Score: 1

    Further, as my BBI provider is capable of limiting me to 10mbps, they could just drop it down to 1mb or 512k for everyone who is running a faster connection and that would help.

  10. Least of our worries on Bird Flu Pandemic Could Choke the Net · · Score: 1

    You know, I just can't see it being that much of an issue...? "The headlines tonight: Millions of internet users are having to make do without tonight after increased internet usage from home users is overloading many of the systems involved in routing traffic around the internet... ... and in other news, Bird Flu pandemic claims another 6,500,000,000 lives across most of ... the world actually."

  11. Algae... reusable too! on $25M Bounty Offered for Global Warming Fix · · Score: 1

    Off course if these genetically engineered plankton warriors could be adapted to survive extended periods "in stasis", they could get stuck in the icecaps should they reform, locking them securely away until needed! A simple feedback loop is thus set up, the icecaps release or absorb plankton proportional to how they are heating/cooling. Fantastic.

  12. Sweet on Purdue Makes Trash To Electricity Generator · · Score: 3, Funny

    90% more energy than it consumes, eh. So all we have to do now is hook this thing up to, say, a pastry factory, a good supply of flour, fat, water and such, and there will be free, unlimited pastry and energy for everyone, assuming we feed the pastry scraps and uneaten pies, pasties and tarts back in the other end! :D

  13. Re:No comments on technical expertise? on CCP and White Wolf Games To Merge · · Score: 1

    CCP aren't like your average EA-buyout-target games company though; they won't go through with something without thinking it through in detail first - and judging by the way they implement change in EVE, they'll judge by people's reaction to their ideas whether they would be appreciated or not.

    They're not going to build a game without the technical know-how, it's just not them.

  14. you mean gas, aye? on Much Ado About Gas Prices · · Score: 1

    There I was thinking this was about the stuff I run my central heating and hob with, until I got to the part about 'trucking prices'.
    Also explains my wondering why I'd not seen any of these news articles about it :)
