Re: 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.

Re: 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.

Re: 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 ammo c...

Re: 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.

We need a windfall tax on the oil companies which is applied to wind farm or LiFePO4 subsidy :D 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 f...

Re: 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 the max...

Re: 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 a smal...

Re: 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.
