Greenhouse: Under the polycarbonate | The 10 Year Challenge Polycarbonate siding on greenhouse I’ve received a few emails from people curious to know more about the greenhouse. When I started researching greenhouse options, I primarily looked at kits. There are numerous online and catalogue retailers that sell all shapes and sizes of greenhouses. Raised beds, hanging planters, and open sides One of the things I like best about the greenhouse is that the sides open up. Here I’ll hand it over to Derek to explain additional details of the project . . . Structure and rafters Framing is 2″x4″ Douglas fir studs set on a 4×4 pressure-treated sill. Heat sink pit and pipe When we had the site prepped for construction, we ask for a pit to be dug so we could set up a heat sink. We chose an approximate 60-degree angle for the polycarbonate roof to provide an optimal sunlight angle (per the U of M article, it should be latitude + 10 degrees).

Solar Water Heating Projects and Plans Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can save as much as $7000 by building your own system. There are just over one hundred projects with full construction details listed below -- all free. The projects range from simple batch heaters for warm climates through closed loop and drain back systems that will work in any climate. One of the systems is our own $1,000 solar water heating system that has provided a solar fraction in excess of 90% through our cold Montana winter. My thanks to the people who have built systems, and then taken the time to send in pictures and descriptions for others to use.

One Per Cent: Grid-scale battery could keep going and going... Hal Hodson, technology reporter We need a big battery for when the sun doesn't shine (Top Photo Corporation/Rex Features) A new battery technology may pave the way for cheap, long-lived power storage that can quickly pump electricity into the grid to compensate for fluctuating renewables like wind and solar. Developed by Yi Cui and colleagues at Stanford University in California, the battery's key advantage is its electrodes, which can run for a thousand charge cycles without degrading. Battery electrodes typically degrade over time as ions in a battery cell repeatedly slam into them and are ripped away again. By coating the negatively charged cathode in copper hexacyanoferrate and using an anode made of activated carbon and a conductive polymer - compounds that allow electricity-carrying ions to move easily in and out - the team were able to build a prototype battery with electrodes that didn't lose capacity over time.

Deep Winter Greenhouses : Statewide : Regional Sustainable Development Partnerships Extension > Regional Sustainable Development Partnerships > Deep Winter Greenhouses A Deep Winter Greenhouse (DWG) is a passive solar greenhouse designed to dramatically limit the amount of fossil fuel required to grow crops in northern latitudes. DWGs are oriented east-west with a south facing glazing wall specially angled depending on the latitude of the greenhouse to maximize solar energy on the shortest day of the year. DWGs are utilized to grow cold hardy crops that thrive with minimal light throughout the middle of winter providing year-round production capacity for small scale farmers and gardeners.

Developer believes greenhouse could lead to year-round crop production in Sandhills - starherald.com: News Just a few miles north of Alliance’s Carhenge, sits another roadside oddity. This one is far less noticeable from Hwy. 87, but could have a world-wide impact. Though it is the midst of winter in the Nebraska Panhandle, Russ Finch has created his own 1,360-sq.-ft. tropical paradise called “Greenhouse in the Snow.” While greenhouses aren’t uncommon in the Great Plains, Finch’s is one-of-a-kind. Walking through the front door of his home, then through a sunroom, one immediately notices a temperature change. The greenhouse is the “fruit” of 35 years of labor, trial and error, and blood sweat and tears. Finch thinks big. “There are no production greenhouses on the Great Plains, because the cost is too high to run them for 12-months per year,” said Finch. The heating system for this greenhouse is a ¾ hp blower motor which circulates air through 1.100 ft. of six-inch tube, which is buried eight feet under the earth. “Our entire energy cost is less than $600 per year,” said Finch.
Sustainable design, zero energy passive solar green home HTM high thermal mass holistic housing consultation packages for the earthhome do-it-yourselfer With over 20 years of experience, we are the original zero-energy green home building company! Sustainable design, zero-energy, passive solar homes are free from mechanical climate control systems for truly independent living. Our website is packed with loads of valuable free information, so please take the time to read all of this passive solar chapter and all of the many detail pages. Learn why high thermal mass (HTM™) dry stack block, mortared concrete block, or poured-in-place concrete wall construction is a much better answer than super-insulated (high R value) air-tight construction for ANY climate. Conventional stick framing, log homes, strawbale houses, autoclaved aerated concrete construction, and especially insulated concrete forms ICF's are simply not feasible, passive solar, sustainable design materials because they don't effectively store and release energy. HTM construction homes will function just fine in any climate, anywhere in the world.

Greenhouses need to stay warm all year round. Greenhouses as a Part of the Home Excerpt from A Pattern Language by Christopher Alexander: "Imagine a simple greenhouse, attached to a living room, turned to the winter sun, and -filled with shelves for flowers and vege- tables. This greenhouse then becomes a wonderful place: a source of life, a place where flowers can be grown as part of the life of the house. For someone who has not experienced a greenhouse as an ex- tension of the house, it may be hard to recognize how fundamental it becomes.

Meet the woman leading China's new organic farming army Beijing, China - We'd been driving for an hour and a half since leaving central Beijing when the car suddenly slowed to a halt. "This isn't exactly where the GPS told me to go, but I think it's the place," says the driver. I look out the window and see a simple wooden archway leading to a plain, one-storey building. The facade is bare except for some words painted in black capital letters. "Who is your farmer? "Yes," I reply. I've arrived at Shared Harvest, a 2.6-hectare farm in the countryside 70km north of the capital, to meet Shi Yan, its founder and chief executive. Yan greets me warmly, wearing a knitted green cardigan and long purple scarf. Opened in 2012, Shared Harvest is not only a completely organic farm, it was also one of the first in China to follow the Community Supported Agriculture (CSA) model, where consumers buy meat and vegetables directly from producers. A trailblazer in agriculture Thirty-three-year-old Yan is a trailblazer in Chinese agriculture. Healthy methods

Who Says You Can't Grow Food All Year Round And For Cheap Interested in building your own underground greenhouse? Here are 5 things you should know… This low-tech technology is a true gift from mother nature. For as little as $300 you can create an underground greenhouse that will provide enough food to live on year-round. A walipini, meaning “place of warmth” from the Amaraya Indian language, is an underground greenhouse with a transparent (usually plastic) covering that stays warm by passively soaking up the sun’s heat and absorbing the earth’s thermal energy. Fruits and vegetables can be grown year-round, making it ideal for communities in colder locations that can’t usually grow their own fresh and local produce during certain parts of the year. This type of farming method isn’t exactly new, Walipinis have been used in South and Central America for decades, including one that can grow bananas at 14,000 feet in the Andes. The institute published a DIY manual on how to build such a structure. via AwesomeJelly Related articles in Green
