Peroxode or Boil this Mummy?

Hi, I found a mummified small animal (possum, little dog, raccoon) under a friend's house, when doing plumbing repairs. It is all there except maybe the feet. I cant really tell, because he is kinda twisted around, and I have not touched him yet. There is some skin, no fur - he is so dry that the live animals arent even iterested in smelling him. I would like to clean and maybe try to articulate him; if too many bones are missing I will just keep his skull. My question is - what is the best way to remove the dry skin? Instructions I have read are all about fresh skin. Should I boil him or just soak him in peroxide to remove his skin? Thank you!

Boiling DranO = Bad Idea?

I need a source of lye for my next project, but I've learned recently that "Red Devil Lye" is getting phased out because of the "War on Drugs."It is my understanding that sodium hydroxide is a main ingredient in Drano (5-10%), and so I'm trying to find out more information about what exactly is in Drano. (Would anything bad happen if I was to boil it?)Oh, and I am referring to liquid Drano, by the way.

is it safe to turn a kettle into a hot plate for boiling solutions?

Hello, i recently realised that my kettle, which consists of just a a kettle shaped container with a hotplate down the bottom, quickly reaches tempuratures in excess of 100 degrees celcius, and so i have considerd getting a second hand one or a scrap one at the local dump shop, to use in my chlorate cell, to periodically boil the solution once per hour to destroy the hypochlorite and re-absorb the chlorine gas which would normally be lost. i intend to remove the little hot plate! i also want to use it, along with some kind of speed controller, or lamp ambience controller or whatever they are called (lamp dimmer), to make a variable tampurature hot plate, using a heat dependant autoresetting circuit breaker to ensure the temp doesnt go above what i want it at. what i need to know, is  it safe, not for me, but for the kettle, to operate for short periods of time without turning off? or would the resistance coil burn out? by that i mean 5 -7 minutes, considering its normal run time is at about 1-2 minutes. or can it safely run on indefinately, with the only damages occuring being melting of wires and the base?

Boiling a fluid to make a inverse water wheel?

Ok, how about this; Submerge a waterwheel type structure with cups facing downwards on one side. Under the cups you have some kind of heating element. The fluid is methanol or some other low boiling fluid. A very small amount of heat from the element will produce bubbles, which rise and are caught in the cups, the wheel turns and can generate electricity or whatever. I'm using this principle in another application, but thought it could be quite an efficient means of generating electricity from heat. If the meths is sitting at forty something degrees and boils around 50, it shouldn't take hardly any energy to tip it over. And since you're effectively generating force from gravity (the weight of the fluid on the other side of the wheel) you're kind of getting ten times your force back. ie producing one litre of bubbles will give you 9.8 Newtons of force (for water, 8ish for meths). So (excuse my dodgy maths) 125 litres of bubbles in an hour would give you 1 kiloWatt hour? One cola bottle per minute, doesn't sound very much and that much energy could easily be produced through concentrated solar. Slight risk of explosion... How efficient do you think it would be, overall?

Which low boiling fluid to use (that won't corrode metals and plastics)?

I'm having a bit of a headache trying to chose and procure a working fluid to use in my solar device. It needs to be low boiling, but as my device so far is involving copper, aluminium and maybe some plastics and rubbers, it would also need to be as non corrosive as poss. Cheap and plentiful are also important, not so much for the prototype, but when these things are ultimately used, they need to be easy to assemble. The four options I'm aware of so far are: Methanol boils at 64.7 °C, I thought it would be easy to get but is turning out quite difficult and maybe expensive, also apparently eats through every material I plan to use. Ethanol Boiling Point: 78.4 °C, easier to get but still corrosive. Hexane Boiling Point: 69 °C, not corrosive (?) but not at all easy to get or cheap. Water Boiling Point: 100 °C, which may be a bit too high. The fluids will be boiling in a non-pressurised but sealed environment, so no atmospheric water will be able to get in or out. Help?

How much water will ten kilowatt hours boil? ie, if I have one kilowatt of solar energy coming in over ten hours and 100% of it goes into heating the water. Also, for extra credit, assume the water is in a black plastic container also in the sun, so the water is preheated to whatever temperature that would be likely to heat it to. cheers!

How to Make and Eat a Nine-Egg Breakfast

The secret is quail eggs. I found the quail eggs' membranes tougher than expected, and I had to pinch them to actually crack open the eggs. Quail eggs taste more "like eggs" than standard chicken eggs -- like the difference between a factory-farmed egg and an egg from my neighbor's chickens that eat grubs all day. You can hard boil them too. I started the eggs in cold water, heated it until boiling, let it boil for 1 minute, and then turned the heat off let the eggs sit in the hot water for 7 minutes. Finally, I quickly cooled them under cold water, and the shells were easy to peel.

Here, space must be allowed for additional air entraining to provide combustion air for complete burning of gases--proper shape of openings below burner top plate will allow for a soft shelled wind screen which will morph into a chimney-like structure surrounding pot or can which sits unmodified on top of Jet Boil, Bushbuddy, wood gas burner or hobo stove Note that a close fit to within as close as 1/4 will increase speed of gases/heat past pot scrubbing off heat to the pot being heated, possibly creating need to raise the height of the chimney I am using this site in hopes of some one who can find me Carbon Fiber "FELT", I am also open to any conversation on this concept / design.

I lnow i am VERY late with this post, and i hope someone still reads it.NEVER DRINK URINE! EVER! WhY? well, for one, fresh urine contains no bacteria, unless you suffer from bad kidney disease, in which case, you probably couldn't pee anymore.so why not drink it? because ALL TOXIC WAIST of your body leaks into your urine. those remain inside this primitive distillation device on the soil ,as mineral salts, the water being evaporated and recondesed on the foil, thus recuperated. so, this thing is basically a sun powered water distillation thingie. in emergency situations, you can distilate your urine by other means too, to drink water out of it. just DON'T DRINK URINE, NOT EVEN BOILED. ESPECIALLY NOT BOILED. the water getting evaporated by boiling, the urine increases the concentration of toxines. you can only boil it up to collect the steams, which condense into water. that's what you wanna drink.

Solution to turning on/off gas: new pump design.

I've been working a couple weeks now on solving the problem I posted here on how to improve my pump design by alternating the feed of ethanol vapour. I got good feedback but ultimately all the solutions involved mechanisms which were going to be somewhat tricky to build and source, which is against the brief of the project I'm working on; being an open source solar tracker concentrator makeable from scrap. In the end I solved the problem by largely redesigning the whole pump. Since it's driven by boiling ethanol, rather than add an extra mechanism for turning the feed of vapour off and on, I reduced the amount of ethanol being boiled, so that it boils itself out after an appropriate period. The vapour is then able to collapse fully, which sucks in more liquid ethanol and refills the system. 1. At the bottom right is the boiler, which holds about 2-3 ml ethanol. 2. This boils and the vapour enters the 'chamber' (the half blue, half white (liquid and gas)), forcing out the liquid, which pours into the wheel, ending up in the main reservoir. 3. This continues until the eths in the boiler has boiled away to the extent that it can no longer overcome the rate of re-condensation in the chamber, which starts to suck, so to speak. 4. This draws liquid from the reservoir, which passes through the boiler, shutting off the boil, the pressure drops quickly and the chamber and boiler refill with liquid. 5. Two valves (the only moving parts, besides the wheel) keep all this going in the right direction. 6. Repeat. The wheel provides the motion for the solar tracker. It's not in by any means powerful or efficient, but the whole thing can be made from a bit of metal tube, some thin pipe, a glass jar and two valves from bike inner tubes (plus a paint tin, bike wheel bearing and some drinks cans for the wheel). I haven't had a chance to try it in the field yet, but powered by a candle it seems to work fairly well. Blog entry here, will post photos and videos when available.
