You edited the Battery article and added 'In addition, in the two-book series "Sneaky Uses for Everyday Things", there are instructions to make a battery from a nickel, a penny, and a piece of paper towel dipped in salt water.' Do you know if the instructions are in each book, or if not which book they are in? I would like to add this as a reference via a footnote, and put the description toward the beginning of the paragraph. I don't want to reference the first book and have someone disappointed not to find it there. Thanks ! Edison 03:40, 29 September 2006 (UTC)[reply]

In doing science projects/demonstration for kids, I like to make sure that they work, having seen teachers attempt to demonstrate some effect and failing miserably, leaving the kids thinking science is a big disappointment. Science boks are full of experiments that generally don't work in the sense of providing an effect that can be seen, felt, heard, etc. It is no problem if it does not at first succeed, since a little effort and experimenting, and trying different approaches, is good preparation fo all lab work, or for science or engineering careers. That said, I once use strips of copper (from roofing material scrap) and zinc (from old ignition cell batteries, the 6" tall ones no longer made), with a pickle as the middle. I had tried all sorts of electrolyte, until I found dill pickles, sliced thinly lengthwise, to be good because they gave the large surface area needed to lower internal resistance and increase output current. Many science projects try to use a potato battery to drive a load which requires more current than it can deliver. A fix is to connect an electrolytic capacitor across the battery. The size must be large enough to drive the load long enough to make an impression: light a light, ring a bell, make a spark via a transformer, or spin a motor briefly. A digital voltmeteer connected across the capacitor provides a buildup to hold the interest of spectators, then a switch closure or pushbutton connects the load to the battery/cap parallel combination. A pile of coins with the saline paper could make any desired voltage and provide even a dangerous amount of current, if they had a cap of proper voltage rating and capacity connected in parallel. Too large a cap would be boring, with slow charging. Edison 18:39, 29 September 2006 (UTC)[reply]

Ok, i put a pic up on AAAA Battery for you. Hollowman512 16:15, 30 September 2006 (UTC)[reply]

I'm sorry. I thought it was some sort of prank and the article also sounds like a neologism which, in most cases, does not have a place in Wikipedia. Can you explain how it is notable in any way? (Who coined the term? Is this term in the dictionary? How many people use it?) If you have problem with my decision you are welcome to place {{hangon}} onto the article and expand further. mirageinred 18:35, 1 October 2006 (UTC)[reply]

Hi mate thanks for the thanks! You see I have compiled a List of villages and municipalities in Slovakia and am going thorugh each region bit by bit. I am also starting articles on all olympic medal winners e.g Leon Moreaux which was on the main did you know? yesterday! and going through films and actors e.g William Garwood. I also started Inner Mongolia Museum and did Tashilhunpo Monastery and Shalu Monastery ages ago. Its just people don't seem to notice!! Have a read of them tell me what you think.

I have noted that you often edit without an edit summary. Please do your best to always fill in the summary field. This is considered an important guideline in Wikipedia. Even a short summary is better than no summary. As you can see from the edit summary tool, you aren't using them very often. Thanks for understanding, and happy editing.

SuggestBot predicts that you will enjoy editing some of these articles. Have fun!

SuggestBot picks articles in a number of ways based on other articles you've edited, including straight text similarity, following wikilinks, and matching your editing patterns against those of other Wikipedians. It tries to recommend only articles that other Wikipedians have marked as needing work. Your contributions make Wikipedia better -- thanks for helping.

If you have feedback on how to make SuggestBot better, please tell me on SuggestBot's talk page. Thanks from ForteTuba, SuggestBot's caretaker.

P.S. You received these suggestions because your name was listed on the SuggestBot request page. If this was in error, sorry about the confusion. -- SuggestBot 13:29, 7 October 2006 (UTC)[reply]

Capacitance VS. Voltage What's better for a capacitor if I want to create a coilgun? High Capacitance or High Voltage? Thanks. Ilikefood 22:00, 18 October 2006 (UTC)

First, CAUTION! Don't work with electricity or stored energy devices, or projectile devices unless you are qualified to do so, and understand and observe all applicable safety rules and precautions and laws. Large amounts of stored energy in any form is inherently dangerous. Electricity from capacitors can cause burns, or even electrocution. Caps can explode if reverse polarized, overcharged subject to excess high voltage, or discharged at too high a rate. High speed projectiles are as dangerous as a bullet. Even the energy in a photoflash can be lethal, since it is at a high voltage (way higher than the battery powering the device) and of sufficinet quantity to stop your heart, just as the "paddles" on ER shows are used to stop or defibrillate hearts.

I would expect a goal would be to achieve the rapid transfer of a large amount of energy from the caps to the coils. Energy of projectile=1/2* m* (v squared) in Joules = integral of current timesvoltage from stored energy, allowing for losses and efficiency. Not all caps are built for high current discharge and they all certainly have voltage limits which must be observed with a large safety factor. From Capacitor Energy stored = 1/2* capacitance*(voltage squared). Twice the capacitance at the same voltage stores twice the energy. It would cost about twice as much, since two caps in parallel doubles the capacitance. Twice the voltage in the same capacitance stores 4 times the energy. But it is more expensive to buy a higher voltage capacitor of the same Farad rating. If a device needs a certain amount of energy delivered in a given (short) time, you can price out the higher cost of better insulation for high voltage and the price of the high voltage capacitors, versus the high cost of more low voltage capacitors. Caps in series to get a higher voltage rating doesn't work well because the voltage divides unevenly according to the internal dc resistance of the caps. It's an engineering exercise. I'm not sure how you would easily measure the internal resistance of a cap to see its max discharge rate, or where the allowable safe discharge rate is specified. I doubt that caps made for general purposes like electronics or motor starting or power factor correction would work well. Again be cautious.Edison 22:24, 18 October 2006 (UTC)

I've left a comment on your Articles for Creation submission, which can be viewed at Draft:Phil Kafarakis. Thanks!  I dream of horses  If you reply here, please ping me by adding {{U|I dream of horses}} to your message  (talk to me) (My edits) @ 03:20, 29 April 2019 (UTC)[reply]

Your recent article submission to Articles for Creation has been reviewed! Unfortunately, it has not been accepted at this time. The reason left by SamHolt6 was:

This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia.

 The comment the reviewer left was:

Cites many sources, but possibly fails WP:NBIO. If (as suggested by the previous reviewer) the three sources listed on the talk page are any indication, the subject does not meet WP:BIO as they do not inherit notability from more notable organizations and companies they have been involved with.

Please check the submission for any additional comments left by the reviewer. You are encouraged to edit the submission to address the issues raised and resubmit when they have been resolved.
