Solar cells and the environment

Question about solar cells. Since solar panels are encased in glass or polycarbonate, does exposure to the elements degrade solar cells? And if so, in what fashion? Corrosion of the traces? water infiltration? etc. etc? Or is it a matter of the fragility of the cells?

Keeping the environment moist or damp

I'm building an aeroponics system from scratch. When I water my roots in bursts of 3 to 5 minutes how can I be sure that the environment stays moist while I am away, I don't want the roots on my capsicum annuum to dry out. Is there anything I can line my 4" PVC tube with to keep it damp inside but without using soil or any geological material or perhaps and organic material that wont damage the cycle? Is this what aggregate is used for?

New water heater

Oh please help me decide( and more importantly convince my buzz word influenced wife), I want to replace my current hot water heater, there's nothing wrong with the current one other than being 18 years old, meaning it's a ticking time bomb waiting to flood my house. So anyways, the local gas concern has partnered with local contracters Tankless install $25 a month of 60 months, minimum spec heater, does not include expensive, required stainless steel venting. $450 rebate Tank heater 40 gallon install $10 a month sixty months, includes venting $350 rebate Now the no brainer, my gas bill is averaged at $41 a month, $30 is actual gas charges, Now, the tankless claims to save "up to 50%" which is marketing speak for "does not save 50%" but let's say it does, I would save $15 a month, the difference between the cost of the tankless versus the tank, so it would be 54 months before I started saving money. And since we plan on "upgrading" to a new house before five years (when I've graduated), I will never see those savings. Guess I really should get the tank heater, what do you think?

How clouds act as an air pump to suck in air. Not how you think they do!

I have been thinking a long time about the biotic pump theory but I still don't understand it.  The math is too hard for me.   BUT it got me to thinking.   It is a point of major dispute in the meteorological world.   Does condensation cause low pressure?  2 russian nuclear physicists say yes,  almost everyone else says no!   So,  I thought and thought and thought.  Now I think I have a simple enough explanation And yes, they may not necessarily cause low pressure under the cloud (probably do)  but they definitely suck in air from elsewhere.  Imagine a fleet of huge doughnut shaped dirigible airships. They are sitting at 10,000 ft just floating there.   Now the commander tells everyone that they must now fly at 5000 ft.   So they turn on their propellers (in the hole in the doughnut) and drop down to 5000 ft by propelling air up  through the hole.   Now staying at 5000 ft is achieved by running the propellers at just fast enough.  So at 5000 ft they are pumping air from under the doughnuts to above them.   Now imagine a cumulus cloud.  Even though it is not fixed in size or shape and it does not have a propeller,  it is doing the exact same thing.  Air is being pumped up the middle and the clouds are sitting lower in the sky than they "should",  because they are sending that column of air up into the sky.   Here is my video to explain it visually.  https://www.youtube.com/watch?v=sPO8dWm_GIg

The Kids Are Alright

Via The Sietch BlogIf I asked you if giving up your car and plane travel (permanently) was a sensible solution to global warming, most people of adult age (lets say 20+) would have a hard time doing that. However the next generation, the ones who are really going to be screwed by the ill effects of the global climate crisis see things a little differently."new generation of green teenagers are prepared to support radical measures to help the planet, says a new study.A survey of 16- to 19-year-olds by the Future Foundation found more than one in eight (13%) supported a ban on travelling by air for leisure purposes, while one in 10 say they would back a ban on cars if global warming continues to worsen.Almost 10% even say they would be prepared to take part in guerrilla activities carried out by environmental groups.Meanwhile others - primarily girls - are so eco-conscious they have developed a whole new strand of teen insecurity: "green angst", defined as anxiety about one's eco credentials. Others said environmental awareness even influences their choice of friends and partners.The report was conducted on behalf of the National Lottery to inform funding of environmental projects."It might sound like these kids have lost their minds, supporting guerrilla organizations?! But when you consider the kind of world they are going to inherit it makes perfect sense. If you knew that your parents generation was going to leave you a doomed world, you might be a little pissed. No one wants to grow up to inhabit a mad max movie.According to the study released today by The National Lottery (UK organization), half of 16-19 year olds (50 per cent) want plastic bags banned completely, 71 per cent think that unnecessary packaging on food should go, and 13% per cent want a ban on traveling by plane for leisure purposes. While a quarter (24 per cent) think there should be increases on the taxes and tolls affecting cars, one in ten is prepared to go even further and would support a complete ban on cars if global warming continues to get worse.Read more here.

Killerjackalope's social experiment results

Well I've been conducting a secret social experiment using shopping bags and the environmental topics everywhere as a media for this to happen. Basically my plan was to see if I could affect the decision of whether or not to take a bag when it's not completely necessary, to change the course of decision I used different phrases and tried to get a more accurate measure by choosing the same people that come in for milk or bread each day.The phrases are:'Would you like a bag?''Do you want a bag''Do you need a bag?''Wee bag there, mate?'Bag?'The results were really quite interesting, the one putting emphasis on need (very subtlety) reduced bag takings by over half in a day, whereas 'Wee bag there, mate?' produced a very high bag taking day because it detracts from the bags impact as an object. The other things I found was that it's actually possible to control some customers bag taking completely, there's a customer that comes in every day to get milk and I have managed to control his bag taking with about a 95% success rate, so shopkeepers unite and we can eradicate unnecessary bag taking, thereby reducing the majority of plastic bags that end up in the street and ocean, landfills are another story, thankfully my stores bags are fully biodegradable...What do you make of all this, and is it possibly a bit much power to give to a shop worker...On another note I have curtailed the efforts of one customer I know as the bag thief, he used to take five or six for various uses, through gentle shame jibing he's now down to one.

Tiny Wind Turbines that Could Power a Home

The wind turbines measure about 14-18 inches in diameter and they can generate an impressive amount of 200 watts for a 20 mph wind, but the wind turbines could do better if the winds are stronger.Selsam's wind turbines are made of high-strength carbon fiber materials which give the turbines the possibility to be hooked as one. This system is very simple and it weighs a bit, as you see, it can be held in one hand.

For Instructables, 2009 is a Green Year

Part of Instructables' mission is to inspire our community to create and share great projects. We do this though contests, theme months, and challenges that are seasonally appropriate, part of a bigger cultural trend, or simply areas where we want to see more great Instructables. This year we've decided that our overarching theme will be "Green."Our Green category focuses on the environment, reuse and recycling, and saving energy or making it in new ways. However, there's more to it. Green projects cut across all of our categories, and DIY is deeply and inherently green. When you make something yourself you often save materials, time, or money, while simultaneously generating less waste and creating a relationship with your project. Because of that relationship, you are more likely to cherish the final product, upgrade it, repair it, or even pass it along to someone else who will also cherish it. All of these actions involve making more with less, and that is fundamentally green. From my perspective as a life-long DIYer, I feel that it's time our culture took an active interest in all things green. I want to make sure the things we do are meaningful. We may have passed peak oil, but we can all work to ensure we pass "peak waste." So, to help inspire you, we'll be running a number of Instructables project contests all with a green theme. Some will be large, and some will be small -- we've even arranged sponsorship to give away Voltaic solar laptop bags and an Epilog laser cutter! To help you plan and get your projects started early and finished on time, we'll be publishing the timing of several of the contests scheduled during the first half of the year. Obviously, I think the best time to do a project is when you're most passionate about it, but I recognize everyone can benefit from a little extra motivation. Things are, of course, subject to change, but if you have even the slightest inkling of a green project, start now; especially since the real prize will be inspiring everyone that sees your work make their own lives a little bit greener.

I got no soldering/electronic skills, but would like to enhance clothes with Arduinos as next project. Arduino runs with 8/16Mhz and i thought, if the mobiles do have that tiny but fast chips, maybe theres a possibility to implant them on Arduino-Boards, but i dunno, if thats possible and howto.

Noob project help, raspberry pi 2 controlling indoor growing environment

Hello everyone, im new to the raspberry pi world. I have raspberry pi 2 module b (the new one with 1g ram) that im not using. i want to use it to control indoor small growing environment. I have 4 x 12v pc fans that i want to control  the speed of, due to the humidity and temperature. I have 3 led bulbs that i want to switch off/on with a schedule maybe in the future i will connect 5 / 12 V small water pump.  and to connect a camera to use time laps. I dont mind of using external power sources for the 12v fans and bulbs. im all new to this world, with the programming i think i will handle, but dont know much about electronics. im searching for easy way to do this,  dont mind of working hard and spending money on this, just need a good ideas and help :) thank you all.
