Build Your Own Underground Greenhouse

interiro

Growing food in the colder months of the year is a challenge, and growers in colder climates that want to extend the crop-growing season are always looking for a better way to do so. Greenhouses are a great option, but they cost a lot of money to construct and heat during the colder months. The American sustainable agriculture non-profit organization Benson Institute has come up with a set of easy to follow instructions on how to build a much cheaper alternative, the so-called walipini, which means “place of warmth” in Aymara Indian. The walipini is basically an underground, pit greenhouse in which it possible to grow vegetables all year, even in the coldest regions of the world.

Energy Efficiency in a High Demand Home

Ray Armstrong’s mountain home in Colorado Springs is a sprawling 5,500 square foot structure, with the living space extending outdoors where the owner’s fish ponds and water gardens are located. Armstrong is an award-winning koi fish enthusiast, and his home uses even more energy since the ponds and tanks, where his fish are, require precise temperature and water regulation. Since such a large home also consumes vast amounts of energy, Armstrong enlisted the help of David Bednarski, owner of Bestway Mechanical in Colorado Springs, to help him install the necessary solar and other technologies to reduce this footprint.

Innovative Solar Oven That Cooks Even at Night

sunfocus1

Solar ovens are a great way to cook sustainably, but they have the drawback of not working very well on cloudy days. However, the new SunFocus solar hybrid oven, made by Sun BD Corporation, takes care of that problem. And what’s more, you can even use this oven to cook at night. This is possible because the SunFocus oven has a hybrid solar and electric system, with the latter taking over once the sun sets or hides behind the clouds.

Harold Turner’s home near Concord, New Hampshire measures 3,370 square feet and was built using the ROSE construction method, which was created to build affordable net zero energy and cost effective homes in a wide variety of geographical locations and environments. R stands for “Renewable energy production,” O and S stand for “Owner driven spatial design,” and E is for “Energy efficient construction,” while the entire house is known as ROSE cottage and serves as a prototype and test bed for future homes to be built using this method. The entire home was built for $175 per square foot.

Solar Cells Might Soon be Made of Paper

solarcellnanopaper1

While living in solar powered homes is very sustainable and environmentally friendly, the materials from which most solar PV arrays are constructed are not. Since they are often made from rare natural materials or plastics, researchers are constantly looking for way to improve this flaw and make the whole package more eco-friendly. A team of scientists from the University of Maryland, the South China University of Technology, and the University of Nebraska-Lincoln have recently developed a type of paper, which is made from wood fibers. This paper is 96 percent transparent and could conceivably one day be used instead of the plastic materials used to construct the solar cells of today. This would make solar cells more eco-friendly as well as much cheaper.
