  1. Re:It's impossible. on MIT Electric Car May Outperform Rival Gas Models · · Score: 1

    We're not quite there, but we're getting quite close. The important thing to remember is that vehicle-sized gasoline engines are stupid inefficient. you get maybe 25% of the gas in mechanical power, and the rest goes out the radiator. Good electric motors are about 90% efficient.

    The car they're using (2010 mercury milan) has a 17 gallon gas tank, so that's 612KW-hr of energy (36KW-hr per gallon). Now divide that by 3.6 for our efficiency gain, and that knocks it down to 170KW-hr of battery needed (a little less than 3x what they're using). Add in the fact that an electric doesn't idle and regenerative braking can be almost trivially implemented and that knocks down our battery requirement even further.

    Mcm is an abbreviation for 1000 circular mils (How the fuck they came up with that abbreviation, I have no idea), and a circular mil is the area of a circle 1/1000th of an inch (a mil) in diameter.

    Converting that to metric, that gives us wire 18mm in diameter, which would be a bit smaller than 8/0 AWG.

    His suggestion by no means precludes your desire. Take APT+synaptic (or whatever GUI frontent you like, or just the command line if you want.), for instance. nice centralized way to get and update programs. But if you want to host .deb files on your own site and not deal with repositories, that works fine too.

    Gasoline will auto-ignite just fine, it's just much trickier to control when it ignites than with spark ignition or diesel ignition.

    Mercades has a engine in development called the diesotto that does this.

  6. Re:bs science as usual- and a waste of time/effort on Laser Ignition May Replace the Spark Plug · · Score: 3, Insightful

    the spark plug ignites the gas already, and it BURNS- how much more combustion could you get?

    It's not so much getting more combustion, but making the combustion behave how we want it to. And there's a long way that can be gone.

    But whether this has any real point compared to other fuels, such as diesel that have a big leg up on gasoline to start with, is up for debate.

    Has anyone considered the meteorological effects of removing all that energy from the atmosphere?

    Yes, and it's insignificant.

    According to the NOAA, an average hurricane releases roughly 14 Terawatt-hours of energy per day. According to the EIA, annual global electrical production comes to about 20 Terawatt-hours.

    To summarize, one single hurricane can power the entire world (with room to grow) for an entire year if captured for two days.

    Now consider how many hurricanes and typhoons there are in a year, how long they each last, and do the math. And don't forget about lesser weather phenomenon like thunderstorms (An average thunderstorm releases about 10 gigawatt-hours) and wind in general, which also release a non-trivial amount of energy.

    Couldn't they just package it up and send it to the moon or Mars?

    I doubt it.

    To move it out of low earth orbit, you would need a large amount of force. The station weights about 370 metric tonnes, and would need to accurate by about 3.5 kilometres per second to reach escape velocity.

    The shuttle's orbital engines will give you 53.4 kN of force for 21 minutes. Using that to push the ISS out of orbit would take about 7 hours.

  22. Re:Car makers shouldnt be making these cars anyway on Toyota Builds a Patent Thicket For Hybrid Cars · · Score: 1

    I'm fairly sure the idea is to have the engine spin at the optimally efficient RPM and drive a generator designed to also provide maximum power at that RPM and that will be more efficient than running the engine at any of the range of RPMs required at various speeds.

    I don't buy it as :

    1. The HSD system already uses a CVT system that keeps the engine damn close to that optimal RPM across the speed range, so I don't see much possible gain there.

    2. The obvious conversion losses you mention.
