    If an Alien gave you a black box

    I would take the alien hostage. If they're just giving away boxes that end all suffering, etc., then they must have some really good stuff in the ship. I'd send them a tentacle and say if they don't give me something that lets me enslave the universe, their friend's gonna be green spaghetti.

    gm killed the ev1 and trollies?

    Everyone knows that the people at GM are such perfectionists that they couldn't stand to let the ev1 loose until it was absolutely perfect. Just like everything else they make.

    What kind of battery box

    I don't have pings, but I was looking at the dimensions, and some would fit very nicely in surplus ammo cans. I use small ammo cans for my dewalt battery boxes. All you need to mount them is a drill and some plumbing pipe mounts. Look on ebay or a surplus website for the dimensions of various...

    Norway Rocks

    Either that is a big bike or the naked girl is only 4 feet high. http://www.kondisjonalis.no/dynamisk/imagegallery/Vannbilde.jpg I thought they were tall people in Norway.

    gas price thread

    Enron was electricity, at least that's what got them in trouble in California. Market manipulation amounting to fraud should always be prosecuted. But oil price increases are largely driven by shrinking supply and increasing demand (China, India and everywhere else). So no, we should...

    No argument there. But I'd rather buy their stock than have the government tax their windfall profits.

    gas price thread

    McStar, ease up a little on brother TD, he's a thinker, and we're keeping this all on the level of great thoughts-- TD, I see it as an advantage that an investor can take his profit when he wants or needs to. He can sell off enough shares to recoup his profit and retain shares representing his...

    gas price thread

    Shell's stock price is up almost 40% from 2 years ago ($66 to $83), Chevron's almost 80% ($61 to $99). S&P 500 is up about 20% over the same period. While I'm not saying upper management isn't wildly overcompensated, shareholders are clearly participating in the profits these companies are making.

    gas price thread

    Last I heard, all the big oil companies are publicly traded, so all anyone has to do to participate in their profits is buy some stock. That's what most pension plans have done, so taxing oil companies for windfall profits is taxing old people's income. Not that I'm agin' government promotion...

    Welding, machining, custom parts?

    You wouldn't believe it, TD, but the donor piece was rust-free, from Washington State. Must have been buried in a peat bog.

    The 14V Regulator of the moded 4110 mosfet controller.

    Hey Doc, I have sometimes been concerned that the regulator is going to see more voltage than its maximum rated input. Usually there is a power resistor of about 1000 to 1200 ohms feeding the regulator. When you increase the voltage the power resistor sometimes lets through near or more than...

    Welding, machining, custom parts?

    How's this? My buddy's '78 VW had rust under the windshield. We cut it out and welded new in. Old pieces are sitting on top for comparison. What, you meant bikes? Ok, here's the throttle I just made. I needed a 10k pot to control a non-standard controller. I had to make it out of a...

    how much is over clocking is safe?

    I've been running my WE brushed motor at 66v for four months or so without issue. It feels like a happy little motor, if that makes any sense.

    solar powered SLA charging?

    What you need is a charge controller and a solar panel (obviously). Charge controllers can be very cheap and low power or sophisticated and high power. Look at Xantrex model c12, which will take about 200 watts and do more than you need. You can charge an ebike easily with a 50 watt panel and...

    NiFE batteries from BeUtilityFree

    You can buy KOH (otherwise known as potash) on ebay reasonably cheap.. Commonly used for the production of biodiesel. No need to ship from China. Any chemical supplier can also sell it too you. Maybe even a pool chemicals store.

    55mph Club

    This is my beef with hybrid cars. That Toyota does as well as my parents' Honda Civic Hybrid which is heavier and way more complicated for all the fancy stuff on it. Honda lies about the hybrid mileage, too, whereas the Toyota does better than it is rated. I was just reading about the new BMW...

    If you can weld and cut steel, get junk bikes and use the headtube/fork assemblies.

    NiFE batteries from BeUtilityFree

    I didn't know these were still available. If they're the same thing I'm thinking of, I have read that they basically last forever. Very heavy and expensive, but perfect for PV power system storage. I suspect the battery companies don't like them because they last too long.
