Hey, I´ve been reading a lot about green technology lately and while doing it I came across something that really surprised me - nuclear powered exit signs. I had already known that both cars and trains, for example, can be nuclear powered but I didn´t realize that an exit sign can use no electricity, even when it´s self luminous. Apparently it doesn´t require any wiring or batteries so I started thinking how I could make an exit sign myself. Btw, does anybody know anything about the regulations as far as the material used in fire exit signs is concerned?

I have had an interest in building a greenhouse like area with flouresent bulbs, automated water, and climate control. For the water i could hook up a hose on a timer to a bit of pvc but what is the best way to get proper climate control. What is the desired composition of a water? I guess the question is how do i get nutrient water and proper vitamins straight to a plant?

NEW QUESTION: Should I grow food, or food and commodities (IE wheat, cotton, etc) Well, I grew vegetables last year, and the crop was a failure. Don't ask me why, since there were at least 20 things I did wrong, and on top of that, mother nature was pissed off at me. Well, I already have some ideas on how I'm going to make my farming more eco-friendly, but I'd like some more, some ideas I have are: No fertilizer (I grew organics last year too) collecting rainwater in buckets to use to water on drier days (I'm going to make a small shed which I can store the water for just such an occasion) Allowing bugs into my garden Also, I plan to compost all the plant waste (I also use my dog's "Waste" for fertilizer... weird, I know, but it works, and it means I don't have to use up plastic bags, or pick the stuff up. Plus, it's better in the ground being broken up than in the landfill taking up space) And some things I worry about are: Moving sand into the area. I hear that sand is better for beats and carrots, but I wonder if it would be a bad environmental change to move sand into the area. It's not a large area of land, but still. Please excuse me if I didn't make too much sense, I'm really confused right now... school is getting to me :(

Hello all! I have many of Cheap and Outdated LEDs (In thousands) lying around. These were purchased long time ago (2003~2005) when luxeon Stars were hardly available and costed Rs 1000 a piece. These LEDs are- 5mm 20 deg White ~100pc 4.8mm "Straw Hat" Low dome 100 deg White.~ Many 1)Both of them are rated at 20ma, 3.2 volts. 2) Straw hats are twice as better (Life, brightness, Even-ness) than low beam angle 5mm ones 3)I learnt the hard way using these in many precious projects. Now I know very well that 5mm LEDs dim considerably even at 20ma after a year intermittent use. I had made 36-LED matrixes (about 2 watts) with good spacing between LEDs, Legs uncut still went dim after a year. 4)There is a huge variation in Tint, Voltage and output of these. Straw hats are better , but still 5)These are not entirely Cheap in money per-se. Costed 3 Rs per piece. Today a reasonable spec Chinese 350ma Star costs 40 a piece. If we consider a bunch of 18 of these to make that wattage, They add up to Rs 55 6)Advices to throw them in the bin/ Donating/ smashing with bulldozers./ Overvoltage Fun etc are not my idea. 7)Don't want to spend tremendous time/energy/money than they're worth.

Hello friends, I personally don't have to use a wheelchair, but we have an acquaintance, who is - after a diving accident - bound to a wheelchair. He raises up the question, about being able to be "offroad" in the woods or mountains by himself, would be a great deal for him. Therefore the thinking of an "offroad-Wheelchair" entered our mind. My brother, who is a teacher in a technical college or school in germany, started some projects, where the students also tried to find good and easy solutions for this task. But it is not easy. Finding this website and finding so many solutions of so many difficult problems of life, I rememberd this task, and think, that this gathering of "brainpower", ideas and idealism, could be a perfect place, to start a project like this. Maybe there are already good solutions among the friends here in this forum of instructables, maybe this could be also a start for good, new ideas, I am interested about the reactions and answers to this topic. What do you think about this idea? What is the best way to go? Let me know! Greetings to all! Steve PS: I think "communities" like this, in sharing ideas for good, with other people, is one of the top-best ascpects of the internet! PPS: HELP - I tried to put this into the section of Assistive Technology, but I dont know how - Is there anybody out there, to replace it there...

Has anyone ever worked with MgO cement? Where can buy it in US? MgO replaces the Ca found in portland cement. MgO cement makes a concrete that will incorporate cellulose and other organics into the crystalline structure. absorbs CO2 instead of generating it, is an order of magnitude stronger than portland, does not require wetting, and cures in minutes. So basically, you can take some burlap or old blanket and paint this stuff on, then fill the void with straw and cement and make super strong, light and thin structures. I have looked for it locally but it does not seem to be available to consumers in the US, probably because of the lack of sheep crap which is the typical source of Mg. It is amazing stuff. This is pretty much the only article I could find about the stuff: http://greenhomebuilding.com/articles/ceramicrete.htm

I'm working on a circuit for an electric trike I plan to build for the local EV challenge competition. I plan to incorporate regenerative "free-wheeling" to recharge the batteries on the down hill sections. S1 closed and S2 open to accelerate the vehicle. S1 open and S2 closed to recharge the batteries while freewheeling down hill. Batteries: sealed lead acid batteries 12V or 24V (depending on motor) Motor: brushed DC motor Would this kind of circuit work? Is it possible to recharge SLA batteries in such a way? Any help and/or suggestions is appreciated. PS. I know it would also be possible to implement regen braking using a full H-bridge, but i think we would be doing more freewheeling than braking on the race track.

Hi all, as an astute long-time reader of people's projects, I found some great ones to repurpose and reuse otherwise not-so-pretty, salvaged or thrift-store bought furniture. However, as I slowly gained confidence in my abilities and availability of products, I sustained my third treatment against bedbugs in less than a year. Nothing unusual in my town where the epidemics is out of control, but surely a time-waster and great source of tension between tenants and landlords. For those who have been lucky not to harbour this pesky little parasite, a treatment involves pulling every furniture from the walls, dismantling every piece that can, turning them upside-down, removing wall outlet plates, placing dirty laundry nearing the bed at the center of the room, waiting for the CPO to spray everything, leave a mess of a (inefficient) white powder everywhere, going outside the home for at least 12 hours, going back, pack everything and go to the laundry, come back and re-assemble the furniture. This is extremely time-consuming, but I got a hint from the CPO that could potentially save hours of work. Bedbugs don't fly or jump, and cannot climb on metal or plastic. Conversely, they are especially fond of wood to live and sticks their eggs on. Incidentally, wood is the most common material to make low-end Ikea furniture. Question is, considering current North American bedbug invasion, why is there no more bedbugs treatment friendly hacks, or at least a word of caution against getting anything used or of unknown origin? That would be as responsible thing to discourage the practice, as we already do about wearing safety googles when using a power tool. And second, why aren't there more hacks and projects with that in mind? As Tim Anderson wrote, most people have more time than money on their hands. Well, I have neither of those (nor a vehicle), and thus cannot participate at that time.

Question by sumit.ahuja | last reply
Some time ago I was approached by an old friend who got very lucky money wise.He wanted to build a really energy efficient house for himself - in terms of being well insulated.Should be easy to build as well he said...So with a few beer we got together one day and tried to figure out what options are available that the usual building companies won't or can't offer.Quite soo we realised that freezer panels seem to be the ideal solution.Sturdy, ralatively high load rating and additional supports, mounts and all are readily available.Funny enough there are even the right thicknesses available to be a perfect match for EU style tripple glazed windows and well insulated outside doors.And as always the initial euphoria meant we totally went over board here.Getting dimensions for selected doors and windows, calculating how many freezer panels are required to make the outside walls and roof...Even starting on 3D models to design the whole thing.Needless to say the dreams ended with an equiry at the council for a building permit for the dream home.Turns out that despite proper ratings on overthing a house can not be built with freezer panels for walls.Only bricks, wooden/steel frames and approved building materials...Either way we kept going as a theoretical game for the hope in a few years regulations around here might change.And you might be lucky to have your property somewhere with no such stupid regulations.One of the biggest problems we realised such a well insulated home would have is moisture and fresh air.Possible solution here is to use a heat exchange system for basically everything inside and outside the house.Options for this already exist for purchase and installation so nothing would need to be designed or developed from scratch.These system combine airconditioner, heating, hot water and air exchange in a quite compact unit size.The required ducting is a different problem though that should be included in the early design stages already.Solar panels double up as additional heat shields so to say and with enough roof space left it could be turned into a green and living roof to help with the carbon footprint and inside temperatures during the summer.So far for the easy part...All this would be impossible without home automation and integration.Sensors monitor conditions, a computer system decides on the right operating parameters and allows for user adjustments.Home automation isn't a new thing either, so called smart-homes are already in the portfolio of most good builder out there - at a price though.Using this technology to our advantage means the smart part now doubles up for the required input and sensor data.For a smaller home you would ideall opt for a rotating home that follows the sun...For a really big home you would aim for enough solar and wind power to make it self sustaining...Battery technology is on our side here and using Li-Ion tech is almost affordable as old style lead-acid batteries for this purpose.So why are there only so few people going this route?Would be very easy to create freezer panel styles that look like wood or bricks to be conform with local appearence...The real problem seems to be that it violates what we are used to.For starters it would be hard to explain why you should live in a big fridge with windows.The next problem is that such homes would be very easy and quick to build.You select your style and design features, pay for it and production starts.In time for the finnished foundations, plumbing and such the parts arrive and come together in a day or two.Connections are finalised and can move in within a week of commencing to build the actual house.Thausands of tradies would be jobless if this would be the general way to build new homes.Same for all those companies that currently supply the standard building materials, frames, roof tiles and such...Just imagine a tornado just turned your home into dust.Wouldn't it be great to be able to move into a new one within a few weeks instead of months?Even better if the new one would still be mostly unharmed after the next tornado....Living in a possible flood zone?Nothing easier than to add some barriers for doors if the house is fully sealed otherwise...Stay dry while the water is right under your window, just don't open the door...In other parts of the world so called kit-homes are already widely available but mostly only in mild climates.The benefit of using freezer style panel for homes in desert or cold climates seems to obvious though.Same for possible disaster zones like tornado alley.Is it time to re-think how we define a home?

I would like to know which type of vehicle is more environmentally friendly. Electric and hybrid vehicles are gaining in popularity and they are touted as green, but they clearly require more energy and resources in their manufacture due to their battery packs, rare earth metals and electric motors. On the other hand, traditional internal combustion vehicles require fewer resources to manufacture. However, I imagine that it converts fossil fuels to energy less efficiently than electrics because the conversion process is smaller, unlike in large scale power plants (not sure if this is true). Electric === More resources to create (-) Power Plant (Generates energy efficiently?) (+) -> Power Lines (A: energy loss) (-) -> Motion +,-,- Gas === Fewer Resources to create (+) Combustion Motor (Generates energy inefficiently? B: energy loss) (-) -> Motion +,- I'm pretty terrible at explaining this, but is the energy loss at A or B worse when comparing the two systems? For electrics to be viable, it must offset the higher creation cost. Just wondering which one is actually more "green" when you factor in production (disregard cost of transporting fossil fuels to gas stations and power plants).

. I had two HDDs fail at the same time on an old computer that the neighborhood kids use to surf the web. I went ahead and retired the old P3/550MHz machine and replaced it with a P4/1.8GHz unit I had laying around. Instead of using Win XP Pro, I decided this would be a good time to start switching my computers to Linux. Downloaded Ubuntu 8.10 and once I figured out that a 2.5GB HDD was too small (Ubuntu would install OK, but run out of disk space when updating) and upgraded to a 20, the install went without a hitch. . Looking for suggestions on "edutainment" apps to install for kids from ~5yo to ~16yo. Computer is a 1.8GHz P4 with 256MB RAM, so the apps can't be resource hogs. TIA.

I can't wait to take a ride on Yamaha's Tesseract. With Motorcycles, Eco-Friendly and Badass Can MixElectric and alternative-fuel bikes are the future of individual transportation not because of their fuel efficiency but because they are extremely cool. That's right. Creators of eco-friendly motorcycles are pushing the limits of their designs to make them desirable to a biking community that sees little difference between their (relatively) efficient gas engines and the new-fuel wave of alternatives. Riding bikes is all about the cool factor, so the crazier and more technologically advanced they get, the more people will want to ride them, clean fuel or not.Gaze upon the alt-fuel bikes most likely to break the mold of motorcycle design in the near future.
