green

Need help form you green people. I would like to take my garage door opener off the "grid" and use my solar charged battery instead. I have a AutoCommand remote starter for an auto to turn the inverter on/off as needed. Tech support first told me this could be done.(Supported by Radio Shack). But their instructions over the phone where very vague. I phoned again this morning and they said, "they would not support a non automotive application for their product." Can anyone out there help me. ldl

Solar Windmills

Of the various renewable energy sources out there, solar and wind are among the most popular. Already windmills are springing up in various parts of the country. This got me thinking, what if you used some of that space on the windmill to harvest some energy. For example, what if you attached solar cells to the windmill rotors of tower to harvest extra power. What do you guys think?

Green isn't all that green after all

While the color green has been the hue of choice for environmentalists and companies wishing to show that they care about nature, making a product green is actually toxic. Due to the difficulty of making a green dye and all the chemicals that are used, it contaminates anything it touches. So when a product is simply putting some green to make it look a little more nature-friendly, it's actually making things worse. Yay! From the NY Times: Take Pigment Green 7, the commonest shade of green used in plastics and paper. It is an organic pigment but contains chlorine, some forms of which can cause cancer and birth defects. Another popular shade, Pigment Green 36, includes potentially hazardous bromide atoms as well as chlorine; while inorganic Pigment Green 50 is a noxious cocktail of cobalt, titanium, nickel and zinc oxide. The Toxic Side of Being, Literally, Green

1.5W Green Laser

Hi everyone. I'm selling my 1.45W (metered) green laser; unfortunately I'll never get around to building a laser harp with her :-/ I'd like to get $800 for it, but this is somewhat negotiable.

Green Clubs

This is to spread the word about green clubs. They are a great way to get together with people and talk and do green things that help our planet. They are also a great way to raise awareness to people about our what could be destroyed earth. Great places to have them are libraries, schools, and even meeting places like local coffee shops. Please help start green clubs. P.S. I am not a Hippie or a tree-hugger.

Yeast fermentation for composting solution?

I threw some hay off my lawn and some green weecds into a garbage can, some sugar and yeast and formented it to slug beer but the slugs did not like it. It then fermented further to vinegar, and a crust of green "Mold?" covered it. seems to have protected the vinegar from further fermentation. I tried a second bigger batch ( morning glory weeds) with less sugar but after a few days of good fermenting it went rotten and stinky. So there are probably thresholds for sugar content. Would the yeast be a way of adding fertilizer to organic gardens? Yeast can (I think) convert urea and nitrate to protein. Perhaps some green stuff has enough sugar to work without sugar addition. vine prunings? maybe. The first batch, i put bleach in to kill off microbes before I added water and yeast. Perhaps hydrated lime would work instead of bleach and also get the ph good for yeast fermentation. This might be a cheap way of liming your garden. (Here in victoria, hydrated type s lime is cheaper than limestone for garden addition. (But it contains more calcium!) The "yeast tea" or vinegar tea could be used on the garden and the weeds could then be transfered to normal compost or used as mulch. It might be an alternative way of using diseased materials of composting seedy weeds to kill the seeds. Brian

Exercycle Generator

63% of Americans are struggling with obesity (http://www.americansportsdata.com/obesitystats.asp). There is also a large green movement going on. So what if we combine these two ideas? I have been looking at instructables on how to build your own wind turbine, and instructables on how to use your bike as a generator for charging ipods and cellphones... why not combine the two ideas and create a stationary bike that puts electricity back into the power grid, much the way a home turbine does? Granted... it wouldn't be much power, but the more you exercise, the more money you save--and the better shape you get in. And those pennies each month add up to dollars each year... and again... the health benefits. It's almost like getting paid to exercise, which can be a big motivating factor. Thoughts?

Software for designing solar cookers and reflectors for solar panels

Parabolic dishes are favoured because they are "perfect". Unfortunately they are only perfect if they are kept constantly pointed at the sun. In practice this is very hard to do. A better shape would maintain good reflection of the sunlight for a long time without moving the dish.I think I have found useful easy software to help with this design work. It is called art of illusion and you can see my first results and a downloadable scene file to help you get started on step 12 of this instructable https://www.instructables.com/id/Make_a_quotcompoundquot_parabolic_solar_cooker/Brian White

Refrigerator Insulation?

Background: I was looking at Costco and they have their big semi-rugged totes on sale this time of year for like $6! The thing I'm pondering is sticking one in inside another and filling the space between with insulation.  But what to put in between? You're probably thinking what I'm thinking, Pinky:  Spray it full of Great Stuff foam. But then I'm looking at my fridge going... that thing is literally freezing inside and not even cool to the touch on the outside!  What kind of insulation do they use?  I'm guessing something trickier than Great Stuff, what with Energy Star ratings and all.  In short:  What is it and where can I get some!??

Reclaiming Wasted heat to make electricity

I work in an aluminum casting facility and we're looking for ways to save energy etc... one thing that we've got no shortage of is heat (during the summer the temp near the ceiling above the furnaces is over 230F) i've looked into stuff like they do in steel mills in Germany where they run pipes through the furnace linings and then use the heat from the furnace to make steam and run steam generators. but i was thinking of something else today. would you be able to just mount a bunch (or one huge) peltier exchanger (or whatever they're called) on the ceiling above the furnaces and use that to make electricity? i'm aware that they create electricity because of temperature differences (and not specifically from being hot or cold in general) so would we have to cool one side of the unit for maximum efficiency? are there any other ways that anyone knows of to turn waste heat directly or indirectly into electricity?

Solar Cells that look like Terracotta Tiles?

So I had an idea that you could make solar cells that looked like Terracotta roofing tiles example. I figured if they were durable enough you could cover an entire roof in them. They're definitely no uglier than standard shingles. Also figured since they're curved you might get more performance out of them, but I could be completely wrong and they could be absolutely useless up there.The only solar cell I've ever seen that didn't look like a giant rectangle was this little, thin sheet that was in the back of a Wired magazine. It could eliminate the eyesore issue that you might run into with the neighbors. I guess the second problem that you'd run into would be how costly this would be. Since you would have to buy them, install them, then wire them through the attic.And for the record, I know absolutely nothing about solar panels, I was just brainstorming ideas....Ideas? Suggestions? Possible? Impossible?

Model a heliostat with a drill press, laser pointer and mirrors?

Mechanical Heliostats were important scientific instruments over a hundred years ago and one mirror heliostats were often used to focus sunlight on an experiment. Better mirrors became cheap and 2 mirror heliostats replaced them. Then electric light killed off both types.But now, solar energy is becoming important again. Big fairly low efficiency mirrors can be made with mylar stretched across a frame. Perhaps now is the time to get 1 mirror heliostat research going again! (With low efficiency mirrors, 70% efficiency becomes 49% if you use 2 mirrors to reflect the light) So you get less efficiency for twice the expense if you use 2 mirror heliostats!But first we need to model the process. It just takes too long to test your ideas outside! Here is the start of my model of mirrors on an equatorial mount (also called a polar mount) and the sun moving on the celestial sphere. I think that it will end up being very useful. I just gotta find the right mirrors and the right laser pointer. A heliostat with the mirrors moving at one rotation every 2 days, can do this perfect reflection but it is limited to certain angles because the mirror must be upright on the mount.In my model, I have left out the earth's surface for them moment. So we will just model the suns movement, the heliostat mirror movement and have a target to see how much the reflection moves too.Brianhttps://www.instructables.com/id/S1QAZI9FS8O1X6Z/

Feedback Can someone test my Instructable "software for solar reflector design"?

I have an instructable about designing better reflectors for solar cookers. (Better than parabolic dishes). Basically you can design your own dish, and compare it to the parabolic dish and other shapes with the software. On step 1 there is a zipped folder for download. It contains an art of illusion scenefile. Art of illusion is the modeling and animation software I used. It is easier to learn than its competitors and it is free. The folder also contains a html file for almost automatic tabulating of your results and comparison with other reflector shapes. I have "starter" jpg images for when you create series of 10 images for comparison. I hope to put in a help html file too but thats all for now. To test it, you do need to download art of illusion too. I know this type of project can be a bit of a pain but with feedback, I can refine it. And where else do you have free tools to test solar reflectors? https://www.instructables.com/id/Use_software_to_design_a_better_solar_cooker/I hope that this will grow. A guy in Finland has already done a rudimentary "sun engine" that will do the shadows from a day as an extension to this project! That could be used to design passive solar houses and to site vegetable and fruit gardens in the best spots. (Depending on the seasons and day length, shadow patterns from trees and houses are very different). This is not something you can imagine just from surveying a site! Anyway, hopefully I will get some input.The instructable has grown and changed a lot as I have improved the scenefile. There are certainly parts that need trimming now. Hopefully I get round to it in the next couple of days. Brian

Going green : Saving the planet project : Come here !

Hello everyone. Looking at the rising of all the awareness programs of saving the planet and going green. I thought why not we here at instructables could gather and make a small team of engineers, electricians, high voltage people, hobbits, and project builders to share ideas on how to save the planet and go green. the main purpose of this topic is to discuss and design new gadgets, machines and mechanisms to save the planet to carbon emission and use of fossil fuel. So if you have a idea people over here could evaluate it and try to test is out......who knows it could be a future source of energy to the world. So your ideas and suggestions are welcomed.

New device gives you green lights on a bike

When you're riding a bike and you get to a stoplight sometimes you won't get a green light. The sensors don't see you and you're stuck. I usually just ride through anyway, but others have sought ways to get the sensors to think you're a car and give you a green.This new device claims to fix this by emitting a frequency to match that of the inductive sensor.The inventor claims that this is more effective than using a magnet like blacksmith_tb does or Kipkay does. Commentors on the site seem equally skeptical and point out that similar products have already been on the market for several years.As for myself, I don't feel like adding what looks like a decent amount of weight to my bike for such an occasional problem that I'll just ride past anyway. What do you think?

Midori no kaaten "Green Curtain"

I just read about an inspiring idea from Japan to lower electricity bills in summer: you mount a wire frame outside the window, plant vines at the bottom, and the vines will grow up the wires, providing shade, a more "organic" feeling, and probably a little more oxygen to the room its shading. This sounds like a GREAT idea! Does anyone know of any fast growing vines that are succulent/lush enough to make this work well?

Instructables in the Daily Green

The Daily Green did a short interview with me about Instructables:  How to Build Your Own ... 5 Questions for the Founder of the Go-To DIY Site Instructables.com.    When Eric Wilhelm started Instructables five years ago, it was supposed to be nothing more than a side project – a dalliance from his day job as a designer at Squid Labs. But Instructables, which catalogs super cool do-it-yourself projects in easy-to-follow detail, has grown into a full-fledged site with a huge following of its own. DIY was bigger than he thought. We spoke with Wilhelm about Instructables, the cult of DIY, and just what makes a homemade Dachshund wheelchair so darn cute. More news and press about Instructables here.

Traffic light plates and other waste glass reuse

What does a municipality do with old traffic lights? Why, they can make them into dinner plates! Recycled Glassworks makes plates from old traffic light covers from retired lights, often the ones replaced with the newfangled LED kind. Oddly, the green lights end up as blue plates... dunno if this is an artifact of the plate-making process or if the light behind is very yellow, necessitating a blue "green" light.But while that's probably their most dramatic product, there's another. Most glass recycling is limited to bottles and jars. The only thing to do with broken windows, or broken glass tabletops, or other glass of this kind, has been to throw it away. Recycled Glassworks accepts this kind of glass in addition to the traffic light kind. They cut it to size and kiln-bake it in a mold (a process called slumping) to produce extremely attractive bowls and plates.Way to go, Recycled Glassworks!

Core77, in conjunction with GreenerGadgets, recently held an open design competition. (See also fungus amungus' post, Design a Green Gadget and Win Some Cash).Well, the results are in, and there are some really clever and/or far-out ideas among the entries. I figured I would cross post some of my personal favorites. Not all of these are great design, good ideas, or even work - some are just purty. Brenn10 already posted the 2nd prize winner, the Gravia gravity lamp, which has since been retracted by the designer due to it's physical impossibility :-).In order, we get:1) Grand prize winner: The EnerJar - an Instructables or Make project if I ever saw one! Now also has its own website with instructions on how to make your own: http://www.enerjar.net/.2) Arc - a very minimalistic wood surface armband/watch. Kinda like J_Hodgie's Solid Wood Digital Clock 'ible.3) Plug-in Watch - such a simple idea that if it isn't on sale yet in Hong Kong, I'm sure it will be by next week...4) Aperture - a shower head that tells you how much water you're using (powered by the flow of water, naturally)5) Powered by Play! - motion powered and operated Wee/iPhone for 5 year olds. Excellent idea, provided they can make it sturdy enough...6) Digital Tattoo Interface - definitely one of the more "out there" submissions...

How do I turn screenshots for my computer into acceptable pictures for instructables?

I have an instructable on software to design better curved reflectors for solar cookers (among other things). Anyways, I put in screenshots of how I use the software and of my results tabulated in a html page with the pictures of different reflectors and how good they are in tables. The screenshots are actually fine but when i upload them they turn brutal. How can i keep the quality of the screenshot after uploading. This is really important for this particular instructable. The screenshots show that for a 1 or 2 hour unattended cooktime, there are several curves that are significantly better than a parabolic dish. But they do not show anything much after upload! I have the most recent one below. Brian

I want to model rays of light bouncing off a parabolic dish with technical drawing, How do I do it?

Basically I want to model the sunlight as it bounces from both a parabolic and a compound parabolic dish. I want just to use technical drawing. It is no problem to model if the dish is pointed straight at the sun but I want to model the rays if the dish is NOT pointed at the sun. On a curve, I will gestimate a tangent to an arc and light bouncing off goes off it at the same angle as it hits it. NO problem it the light arrives parallel to the plane of the dish but most of it will not arrive like this. How do I do it? Just with elevation plan and sideviews and sections through the dish.Thanks Brian It is in relation tohttps://www.instructables.com/id/Compound_parabolic_dish_making_a_template_with_te/

solar watch winder ideas needed

This is kind of lame, but somebody gave me a ROLEX as a gift. The problem is, i never wear it because everytime i think about wearing it the thought of winding it, and then setting the date and time is a deterrent. there is apparently a pretty big market for watch winders that you have to plug in, and a decent market for lithium ion battery winders too.  what i want, it to build a little solar winder and sit it near my window and whenever the sun hits the solar cells it rotates the watch, keeping it charged.  i just don't know what i need to do to make it happen and the information i am searching for isn't out there.  does anyone know what i should buy, and what motor would work to rotate a watch and whatever piece of tape-covered sheet metal i attached the watch to?

Solar reflector mounted on part of an office chair, might give people some ideas.

Http://www.youtube.com/watch?v=VhpwOD2gZLA is a video that shows a solar reflector that I made from mylar and an 8 by 4 sheet of corrugated plastic. I approximated a parabolic dish by cutting it to  make cones. I used bamboo to make it more sturdy. (Still needs more bamboo). It is on a stand made from an old office chair.  I intend to line up the mount properly and put it on equatorial mount but that will take a while. It might be weeks before I have time to test the thing so here it is for now.   I am slow at the experiment stuff. The dish started last september! And it took me that long to figure out how to keep the shape resonably tight. So here it is at this moment. It will change a lot before it is finished but no reason not to show the current state of the project. Brian

Kyoto Trough, is it greener than the Kyoto Box?

The idea behind the Kyoto Trough is to use a parabolic trough (rotated inwards round its focal line) so that all the light it collects over a certain time (1 2 3 or 4 hours) focuses BELOW the focal line. Then you use other troughs (probably facing at right angles to the first one) to concentrate this light further onto the cooking pot. I have done a rudimentary test in software and the concept does work there. I think it will also work as a panel cooker. It is very important to line up the primary trough with the path of the sun across the sky. It should also work as a panel cooker. Just a much longer panel cooker with the v shaped little wings like in the diagram Or perhaps a panel cooker with just one "tail" going up in the air and insulation on the back half of your cooking pot? (taking away one half of the device) Thanks Brian
