Managing high-voltage lithium-ion batteries in HEVs

From EDN (Electronic Design News), comes this article: Skyrocketing energy prices and the growing concern over carbon emissions have focused attention on electric and hybrid-electric vehicles. New lithium-battery designs will be key technologies for efficient EVs and HEVs.By Michael Kultgen, Linear Technology Corp -- EDN, 4/9/2009Safely getting the most energy and lifetime from a lithium cell requires some sophisticated electronics. One requirement, for example, is the ability to measure the voltage across every 3.7V battery cell in a stack of 100 series-connected cells. How do you cope with the 370V of common-mode voltage and reject 100V of common-mode switching transients? The design of battery-management systems for EV (electric-vehicle), HEV (hybrid-electric-vehicle), and UPS (uninterruptible-power-supply) applications requires solving many such problems.How do batteries make cars "green," ...

How do you remove an image from an outdated silk screen?

Is there a way to remove the image from the fabric after you are done with it in order to use said fabric for another design? We have professional screens and equipment that we picked up at a garage sale some time ago and would love to reuse the screens with our own designs. Any help would be greatly appreciated. Even if it can only be done on newer emulsions (we have a few blanks) it would be helpful. Thanks in advance!

Terrestrial mass planet measured orbiting nearby red dwarf

From Science Magazine:A group of astronomers today announced the discovery of the least massive planet yet detected outside of our solar system. It is lightweight enough--between two and three times the mass of Earth--to almost certainly be rocky like Earth rather than a huge ball of gas. Although the planet orbits too close to its star to be habitable, a new analysis of one of its neighbors suggests a world with deep oceans.The observation of Gliese 581e, made with the usual radial-velocity residuals fit, is of a terrestrial-mass planet orbiting insanely close to a red dwarf star. Nevertheless, it marks a substantial improvement (a factor of three in mass) in the precision of the radial-velocity technique.Read the whole article (let me know if it's password protected) for details.Another news article (including a very nice diagram of the habitable zone as a function of the mass of Gliese 581) is available from Science News.

Talk like Shakepeare day!

Thursday has been declared Talk like Shakespeare day! We don't know exactly when he was born, but we're calling April 23 close enough! Readeth the proclaimationeth. Refuse to speak in any tongues save ye olde english Thursday, and force your friends to do the same! Here are 10 quick tips on how to talk like Billy from Instead of you, say thou. Instead of y'all, say thee. (This one will be hard for me! :D )2 Rhymed couplets are all the rage.3 Men are Sirrah, ladies are Mistress, and your friends are all called Cousin.4 Instead of cursing, try calling your tormenters jackanapes or canker-blossoms or poisonous bunch-back'd toads.5 Don't waste time saying "it," just use the letter "t" ('tis, t'will, I'll do't).6 Verse for lovers, prose for ruffians, songs for clowns.7 When in doubt, add the letters "eth" to the end of verbs (he runneth, he trippeth, he falleth).8 To add weight to your opinions, try starting them with methinks, mayhaps, in sooth or wherefore.9 When wooing ladies: try comparing her to a summer's day. If that fails, say "Get thee to a nunnery!"10 When wooing lads: try dressing up like a man. If that fails, throw him in the Tower, banish his friends and claim the throne.

has anyone built an above ground potato planter, with recycled materials? Answered

I saw one for sell a while back but it was expensive. (it didn't use recycled materials) after going through this site, i thought best to ask. I want to plant potatos, but i don't have too much space nor am i going to go to the community plot because when i'm gone for a week or so, i know my neighbors won't water my plants. so i was wondering if anyone has built an above ground potato planter that can be easily opened for havesting. my neighbors would water my plants in front of my apt. it couldn't be bigger than a 10 gallon pot, because if i have to tip it over to get the potatos out it might be too heavy for me. so i'm hoping that you much more intelligent people, because i get stupmped when i start thinking of things, can help a girl out. i'm hoping that you can do this out of recycled materials so that way i can slightly revise without buying much... ' starving students' is what i'm trying to not let my family be... so any help would be great.
