Tesla Powerwall Private Solaranlagen bestehen aus Solarpaneelen, einem Wechselrichter und jetzt einem Stromspeichersystem, um die überschüssige Sonnenenergie für späteren Bedarf nutzen zu können. Solarpaneel Die Solarpaneele, die meist auf dem Dach angeordnet sind, wandeln das Sonnenlicht in Elektrizität um. Stromspeichersystem Die Powerwall speichert den Strom von Ihren Solarpaneelen oder günstigen Nachtstrom aus dem öffentlichen Stromnetz. Wechselrichter Verwandelt den Gleichstrom von Solarpaneelen oder einem Stromspeichersystem in Wechselstrom, der von den Elektrogeräten, Lampen usw. in Ihrem Haushalt benötigt wird. Die Powerwall, deren Gehäuse für Innen- oder Außengebrauch konzipiert ist, beinhaltet einen aufladbaren Lithium-Ionen-Akkumulator (Akku), eine computergesteuerte Flüssigkeitskühlung, das Akku-Managementsystem und einen intelligenten DC-DC-Gleichrichter, um einen stabilen Stromfluss zu gewährleisten.
Green Building Elements | From brick and mortar shops to city planning, we cover sustainable trends in construction, renovation, and more. July 19th, 2015 by Stephen Hanley Add hemp fiber to lime and you get a lightweight building material that can be shaped like a cinder block. When fully cured, it floats in water. Buildings up to 10 stories tall have been built from hempcrete in Europe according to Philly.com. Hempcrete is made using the woody, balsa-like interior of the Cannabis sativa plant (the fiber for textiles comes from the outer portion of the stalk) combined with lime and water. Though it lacks the structural stability its name might suggest, hempcrete does provide natural insulation that is airtight yet breathable and flexible. Best of all, hempcrete is a sustainable building material because hemp can be grown and replenished relatively quickly. But first, society needs to unlearn 75 years of lies told about hemp by promoters of wood, paper and plastics products. In fact, hemp has no pharmacological connection to the its cousin, the marijuana plant. Photo credit: Tiny Hemp Houses About the Author
Homemade Solar panels At the end, the solar absorber is painted black and placed in the diy solar panels casing. The casing is covered with plexiglass that we attach to the frame and thoroughly corked with silicone. Polycarbonate / plexiglass is slightly convex in order to gain greater strength. You can see installed solar absorber without plexiglass in picture 18. Complete solar collector is shown on Picture 19, and finally, installed solar system can be seen in Picture 20. On YouTube you can see how our diy pop-can solar panels work. Important note: Our solar system is not able to accumulate thermal energy after producing it. Differential thermostat (snap disc) controls the fan. If on/off temperatures are set carefully, diy solar panels are able to produce an average 2 kW of energy for home heating. Dress rehearsal of solar collectors carried out in the backyard before installing the system on the house.
Solar Power 101: Batteries Part 1 by Jeffrey Yago, P.E., CEM This article is the first in a series of what will be a beginner's course in solar electricty. Simultaneously we have instituted a Home Energy Information (www.homeenergy.info) section on our website where you can ask questions of Jeff Yago, the author of this series. Yago is a licensed professional engineer and certified energy manager who has writtten many energy articles for BHM. He has extensive solar thermal and solar photovoltaic system design experience, and is author of Achieving Energy Independence — One Step At A Time, which includes many solar system wiring examples. Those interested in solar electricity will want to save these articles for future review when planning your solar system. I am getting numerous requests from readers wanting very specific guidance on how to install their own solar electric systems. During the next few issues, I will take you through the "basics" of solar system design and installation, and answer your specific questions as we go along. Batteries

Eco Homes from the Earth: Cordwood Wouldn’t it be nice to own your own green dream home, made with recycled and natural materials and packed with custom features? Whether you’re an experienced builder or have never picked up a power tool in your life, you can build a natural eco-friendly home with user-friendly, low-cost materials like cob, cordwood, straw and the dirt and wood from your own land. These natural building techniques produce beautiful homes with a small ecological footprint and tons of personality. Cordwood (images via: daycreek, cordwood masonry) From far away, it looks like stone masonry – but get up close and you’ll see that cordwood buildings are actually made from wood stacked firewood-style, and mortar. Soft woods like cedar and pine are used because they are more stable, with less expansion and contraction. (images via: home-n-stead) by Steph / via WebEcoist

We've even seen one solar-powered grill. But we haven't seen many solar cooking options that can store heat for longer cooking times or hotter temperatures. Until now Derek Ham writes over at Barbeque Lovers about a solar-powered grill project he has been working on that uses latent heat storage to both extend cooking times, create hotter temperatures, and reduce the problem of intermittent sun. If successful, this grill could both alleviate the well-known environmental impact of traditional charcoal grilling, and also offer a cleaner, greener and more socially sustainable cooking option in the developing world: Of course this design is unlikely to excite the purists who are addicted to the taste of hickory. The students are currently conducting an online survey to gauge the grilling habits of potential customers. via: Treehugger
Strominventur - Stromverbrauch beim Elektrogrill Der Stromverbrauch beim Elektrogrill niedriger als man vermutet. Da der Elektrogrill nicht dauerhaft mit voller Leistung heizt, liegen die Stromkosten bei unter 1 Euro. Den tatsächlichen Stromverbrauch können Sie mit einem Energiemessgerät leicht ermitteln. Auch Möglichkeiten, um den Stromverbrauch beim Elektrogrill zu senken, gibt es. Welchen Stromverbrauch kann der Elektrogrill haben Elektrogrills haben üblicherweise eine Leistungsaufnahme zwischen 2000 und 2500 Watt. Diese Stromkosten entstehen aber nur, wenn der Grill dauerhaft mit seiner maximal möglichen Leistung heizt. Welchen Stromverbrauch hat der Elektrogrill in der Praxis In der Praxis heizt der Elektrogrill auf die gewünschte Temperatur auf und schaltet sich dann aus. Während der Einschaltphase entsteht ein Stromverbrauch in Höhe der Maximalleistung. Stromverbrauch beim Elektrogrill messen Um den Stromverbrauch bei Ihrem Elektrogrill zu ermitteln, können Sie den Stromverbrauch mit einem Energiemessgerät messen.
Mobile home makeover: Before and after Looks like "Fixer Upper" Joanna Gaines may have some friendly competition when it comes to home makeovers. Amy Shock Amy's mobile home before the makeover. Gaszton Gal Los Angeles-based designer Amy Shock took a low-end $5,200 mobile home in Ojai, California, and turned it into a high-end dream house, complete with floor-to-ceiling walls of glass, a modern kitchen and a large, inviting deck. RELATED: Carmen Electra's new home is surprisingly traditional — until you step inside Amy's mobile home after the makeover. According to the LA Times, the 800-square-foot property took 12 months and about $175,000 to renovate. "The situation was attractive to me," she told TODAY of choosing to buy the mobile home. "The idea that I could purchase the opportunity for $5K was mind-numbing to me," she said. And resuscitate she did. A graduate of the Cornell University School of Architecture and residential designer, Shock conceived the idea for the update on her own.
