The Eco Powerplant

  Creating a Permanent IcePack in the Eastern Sierra A permanent Ice pack in a north south valley of the Carson Basin could insure constancy of water supply to Fallon area farmers and ranchers. Creating a permanent icepack in Northern Nevada is technologically and economically feasible, given the right location . This project will be solar powered, and serve as a peaking unit during times of high electrical demand. This technology will produce energy from solar by PV Panels mounted on a giant spanning grid over a north south valley in the eastern Sierra. A properly excavated mine could also serve as a location. Proximity to gas distribution and an electrical sub line are also important . This facilities' economic importance as a producer of LNG from surplus stock cannot be overstated. The upper part of the oval consists of a space grid spanning the valley or excavation. It is covered with steerable PV panels. The PV panels may be inserted into the grid or used to create liquid air , which in turn can be used to produce LNG. The thermal energy storage as liquid air would be contained underground in the mountainside itself.In Northern Nevada, these mountains are usually solid rock formations imbedded in sandy detritus, an excellent insulating material. Vast amounts of wind power are also available during spring and summer.   During summer peak demand, liquid air could be re expanded to run generators.   And most importantly , this plant will produce as a by product of its operation large amounts of water in the desert by freezing the ground on which it operates. Wet air passing over an expanse of frozen mountain rock will condense, and either form ice or rain. The production and maintenance of a liquid air production and re-expansion facility will also produce large amounts of water during times of high humidity.   Suitable locations in the Eastern Sierra would by necessity by close to either the Truckee or Carson River Basin.

Eco buildings for free?

I'm organizing a community lead market garden project within Wales (UK) to help those most in need within our community. We have little to no money for this project as almost 90% of the volunteers are unemployed, privet funding for our project is hard to come by  we have only found about £400, so we are intending to use as much recycled stuff as we can. I really need plans for a con and tire or wattle cob storage shed/ shelter for myself and my volunteers to hide out in when the weather turns bad And also some plans for a soda/plastic bottle green house. If you can help please do as i've not done anything like this before!

eco-friendly exit signs?

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?

Eco-conscious: Compact Fluorescents

My friend Rawhide did a decent bit of research into the best type of compact fluorescent lightbulb, so I'm sharing is findings here. Do you have anything to add?Rawhide on compact fluorescents:In all my web searching I couldn't find a truly exhaustive comparison on lightbulb stats. Even Energyfederation.org, which was the most comprehensive, didn't list the CRI for all of its bulbs. What I did realize was that the "bright white" bulbs I bought from Home Depot were of the wrong color temperature to mix with incandescents and that is why they looked so cold. I also found a couple of people who really liked N:Vision, the Home Depot brand.So I decided to give Home Depot another shot and exchanged the bright whites for soft whites. Curiously, when I went back the CF bulbs had a big display that wasn't there the week before with the bulbs I wanted in $9 4-packs, which was much cheaper than the individual bulbs.I replaced all the bulbs in our living room and dining room and I (and the nameless other) find the light quality to be quite good---it wasn't possible to distinguish the CF from the incandecent bulbs once they warmed up. If you look at the light in the room as a whole, there is the slightest bit of 'vibration', but it's really not noticable unless you're looking for it.Net savings: 600W->140W to light the two rooms. Awesome.Finally, as a coda to my quest for compact flourescents, I learned that Massachusetts is offering a $2 rebate per package for Energy Star lights and that Home Depot also sells 6-packs for $10. So, you can get 60w replacement bulbs for $1.30 rather than $4 or $5 you sometimes see. http://www.myenergystar.com/rebates.aspx Retailers need to supply the coupons, which are instant rebates at the register. There are also bigger rebates, like $75 off a dryer and $20 off a torchiere light fixture.

Self charging an electric bike?

Hi all, I am always amazed at the ingenuity here and after many years of being fascinated I would like to ask my first question.  I'm thinking of getting or converting/building an electric cycle.  I've been told by local dealers that none except the very expensive have a recharge facility for sat when you go downhill or are freewheeling,  That seems a waste to me so I am thinking ... why not buy a used wheel with a hub motor and fit it at the front wheel and that raises the following questions in my mind ... Can hub motors be used in reverse as generators?   Would the output be speed (rpm) dependent and if so then if said cycle has say a 36 volt system would it only charge the battery if the 'generator' is producing 36v or close to? If so would it be better to find perhaps a 24v hub motor to use as a generator and charge the battery via a variable input, 36v output step-up? I appreciate it will be less than 100% efficient when both using electric at the motor and charging at the 'generator' but would anyone have any idea how inefficient?  I'm fit enough to cycle on the flat but would appreciate help on the hills!! I assume I will need a diode or similar ... does anyone know where I can find a suitable circuit diagram Lots of questions I know ... sorry. David

Bacon bowls and cool eco wallets

I was browsing around some of our referring sites this morning and I found a couple of interesting posts on notmartha.org. Bacon Cups >> I had an occasion calling for bacon themed food and my mind immediately turned towards the famed bacon mat. I needed something a little more single-serving though, so I decided to attempt bacon cups. In the bacon mat instructions there is mention of draping the mat over an overturned metal bowl and cooking it so that it would turn out in as a bowl shape. I decided to try using the backs of various muffin and mini cake pans, I ran out of bacon before I got to try as many as I would have liked so I'll have to try more at a later date. Any excuse for more bacon. DB Clay Wallet >> The people at DB Clay gave me a Version 3 wallet to give away! I hope you don't mind if I had a little look at it, it's excellently manufactured. DB Clay makes limited edition wallets out of a material they call Tope: "Tope is strong. Tope is durable. Tope is heat and cold resistant. Tope is smooth textured. Tope is water resistant. Tope is robust. Tope is eco friendly." The material feels great, and I bet if they sold it by the yard Etsy makers all over the world would buy it like crazy. I thought these were really cool wallets and then I found out you can get one for 50% on their website for the next 6 hours. So if you want/need a cool wallet, here's your chance.http://www.dbclay.com/

Eco-conscious: Cloth Grocery Bags

My friend Rawhide did a considerable bit of pre-consumption research into cloth grocery bags, so I'm reposting his conclusions here. What are your preferences?Rawhide on cloth grocery bags:I wound up buying these bags since they were lightweight, under $15, and could stand on their own.Overall, I've found them quite nice. The nicest thing is that even a large grocery trip fits in 4 bags, so it's just easier to move them from the cart to the car and the car to the house. They do stand on their own, though they have to be fully open and placed down with a modicum of care; I guess they are exactly like paper grocery bags in this regard.Baggers deal with them fine, though I have to thrust the bags on them. I've never had one really notice the bags until I plop them down. Even then they sometimes reach for the plastic out of habit.

Farming - I need some help

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 :(

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.

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.

Patagonia has expanded its Footprint Chronicles website to include five more items. There are now 10 items that you can check to see how far it traveled, how much CO2 it put out, how much waste was generated, and how much energy was used for the entire process of manufacture and shipping.These numbers don't include all of the processing and the shipping to the consumer in the end can't be factored in, but it's a strikingly open way of showing what goes into the making of a product. And for those who are concerned about cargo ships spewing CO2, that's one of the smallest problems."The Chronicles revealed that transportation makes up only about 1 percent of our overall energy use," said Dumain. "Had we listened to the current media buzz touting transportation as the largest factor in energy consumption, we might have greatly misplaced our efforts by making strides to geographically shorten our supply chain -œ which would have massively impacted our business financially, logistically and perhaps even effected product quality Ã-œ and we would only have reduced our energy savings by 1 percent. Instead, we are focusing our energy on areas where we can truly make a difference -œ right in the heart of the manufacturing process." Linkvia Treehugger

Eco-conscious: -167 Watts and No Iron Wrinkle Solution

First, sorry for the blurry pictures - I've changed some sort of setting on my camera and now it's very difficult to get a good image without a tripod.I like canida's segments and thought I'd throw in some of my little bits. Not as significant, but in terms of consumption, every little bit helps ;)First, do you really need 180 watts of light in the bathroom? Personally, most of the time I'm either in the shower or taking care of nature's call as opposed to actually using the mirror.Estimating 2 hours/day usage. We save a little more than 10KwH monthly. So about $1 a month (this bulb pays for itself in 2.5 months).Second. I don't like my dryer. Some of my clothing is air dried or only partially dried by machine. Wrinkles are a problem for me. So my anti-iron solution is a hook in the bathroom. After a few showers (or one way too hot shower), the moist air will release most of the wrinkles. If you really need every wrinkle out - then fine, go ahead and fire up the iron. An alternative to an iron is a steamer. I have the kind that you add a little salt to the water and uses much less power than a conventional iron (this statement was verified empirically).Perhaps there should be a group :) "Semi-Off Grid" :P
