    what vehicle would you want if/when society collapses?

    Why not bury freeze dried food instead?

    what vehicle would you want if/when society collapses?

    My first choice is an ECAT steam engine powered Hummer, with armor, maybe a few CO2 lasers, but Rossi is behind on his schedule, so I'll settle for this wood burning machine as I cruise the dirt roads of a post collapse dystopia looking for cigarettes:

    A123 20Ah Quebec Group buy(Canada) cells ARRIVED 24.57$/cell

    Doc, I have always been curious about real life longevity testing on A123's LiFePO. We agree, this chemistry is superb when compared to the competition. Have you seen any data out past 1000 cycles? And thanks for that video, awesome power. --Mike

    Safety Warning on Compact Florescent Curly Cue bulbs by CAT

    The table is from this: http://www.lamprecycle.org/public/images/docs/LD+A%20August%202009.pdf The old 40 watt tubes had 40 mg Hg in them. Regarding phosphors, while there is plenty of third hand info claiming it can worsen a wound, there is zero authoritative information I can find. If a...

    Is this the same KnightMB that sold us out?

    https://bitcointalk.org/index.php?action=printpage;topic=658.0 (I don't have any where near a full understanding of what is going on here, but knightmb does look like he is in way over his head)

    This man may change the world Andrea Rossi & eCat

    bigmoose, another clue to all this is how laid back the authorities are. If there was any chance that Mr. Rossi can make H2 and Ni fuse, than there is some chance he could make a lot fuse just by varying the ratio of "catalyst". I would imagine his stuff was checked out a while ago by...

    This man may change the world Andrea Rossi & eCat

    Well, I am impressed. The power to weight ratio has to be better than a Naval reactor already, I'm guessing, and if you just got rid of the empty space and the metal container, 9000 lbs of hardware puts out 1400 hp continuous (80 kg each, 52 ECATS). The GE Locomotive division is going to be...

    Its a long read, but worth it http://newenergytimes.com/v2/news/2011/37/NET370.shtml Rossi has done a very good job at selling very little. I don't know if he made a mistake with the steam and fooled himself, or whether he is doing this on purpose, but he even fooled Nasa chief scientist at...

    The thing is, there is no demonstration of 15 kw. 15 kw will move a Jetta at 70 mph :D . 15 kw of steam would be unmanageable in a small room. 15 kw is real power. BTW, there is plenty of evidence of something going on with LENR.

    This man may change the world Andrea Rossi & eCat

    The lipos in the mounting board might work pretty well. The heating element could be in parallel with the lipo stack . To charge the lipos, increase the voltage from the lamp dimmer modules (the blue power supplies, here http://www.gsei.it/attachs/P020_01.pdf ) to the heating element. No need...

    There is one explanation which leaves Rossi with some dignity intact. He bungled the early experiments, but believes he has LENR, although now he has technical problems, and is being "forced" to offer what evidence he has. That is if he is being sincere. (edit, Rossi appeared to be confounded...

    Or he could set up a demonstration in London or Paris, run it for a day, and start an auction. If it worked at all, he would walk away with more money than he could ever spend. :D After following this for a few months, I am leaning towards the idea that Rossi bungled his experimental design...

    charging LiFePo4 with solar cells

    Amanda, sorry for any confusion, but I thought you had brought up the end of charge issue: Once you get any shunt low, you need to limit the charge current to whatever your shunts can handle. I KW of solar will make 70 - 80 amps at 12 volts. Not trivial to handle. Your comments point out the...

    charging LiFePo4 with solar cells

    Texas, Well, I was wondering how to find out if there was an active balancer that looks at V to V. Can it scale up? And with reference to Amanda's comment on flat V vs SOC in the middle, does this affect how they are working? Mike (edit) Bigger capacitors for scale up?

    charging LiFePo4 with solar cells

    Amanda, In PA we see about 3 kwh each day from each 1 kw of panel during Nov-Mar. Not that simple of course, with day to day variations. One idea on what to do with a nearly full battery and SUN would be to move some AC loads off grid with relays (listed for this purpose, like IOTA's). For...

    charging LiFePo4 with solar cells

    Amanda. tks for the quick response. Read the thread over at Field Lines. I am much the wiser. As for schematics, you have already clearly explained what you have built, and left enough schematics elsewhere, thanks for the thoroughness. My main interest is in how well the LiFePOs are doing...

    charging LiFePo4 with solar cells

    "an alternative might be to use a cell balancer" OK. Pardon my cluelessnes, but will the balancer work when the battery is only 70% full, as might obtain at the end of each solar charging day, many days in a row? Also, the PV charge controllers are built to last many years in service, so...

    charging LiFePo4 with solar cells

    Commanda, I am looking at ways to direct connect PV to a smallish (two kwh or so usable (3 kwh then if LiFePO)) 12 V system to power some loads. I have been wondering if the G/F shunt regulator would work on a 4 serial LiFePO arrangement, and so seeing you have one running is fortuitous. Could...

    Even Newer 4 to 24-cell Battery Management System (BMS)

    What do you recommend for a good trade off between quality, efficiency and economy in a 48 volt charger? I know I could find it here on ES, but i just did a search for that and it retuned +1000 instances (nuff said) :( Also, I have been following the threads on these boards for a while...
