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

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
Introducing Oracle Application Express This section describes Oracle Application Express, its architecture, and the environment for using the product. It also introduces you to concepts and terms used in this guide when discussing Application Express. This section contains the following topics: About Oracle Application Express Oracle Application Express is a rapid Web application development tool for the Oracle database. From the end user's perspective, the deployed applications require only a browser and access to an Oracle database running Application Express. Understanding Oracle Application Express Architecture Oracle Application Express installs with your Oracle database and is comprised of data in tables and PL/SQL code. Whether you are running the Oracle Application Express development environment or an application you built using Oracle Application Express, the process is the same. The application session state is managed in the database tables within Application Express. Description of the illustration arch_epg.gif
Free Interactive Design Tools for Solar Power Energy Systems iframe - How to Embed an Apex website on my HTML Website Solar Grill Stores Latent Heat For 25 Hour Cook Time At 450 degrees Image credit: Derek Ham/Barbeque Lovers We've seen a DIY solar cooker built from old CDs, and we've seen plenty of commercially available solar ovens too. 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.
Food Freedom | Decentralize, Grow Your Own, Buy Local. Light Clay-Straw & Solar Hal Brill and Allison Elliot’s light clay-straw home brings together passive solar design, active solar technologies, natural materials, and an efficient layout for an energy-saving, durable dwelling. Home Power (HP): Besides incorporating solar technologies, your home has some unique features. What served as your initial inspiration? Allison Elliot: The development process took several years. Key inspiration came from architect Michael Frerking’s house that was featured in a 2005 issue of Sunset magazine. We fell in love with the curved roof, and that really landed the design for us. The overall design is dominated by this curve, which evokes Anasazi cliff dwellings and our experiences in the canyons of Utah on raft trips. HP: Why did you decide to use clay-straw (or “light-clay”) as the wall infill material? Elliot: Through the years, we attended numerous sustainable building conferences, including the International Straw Builders Conference. Clay-straw seemed to be the middle ground.
NativeBase | The missing piece of React Native Home Made Wind Turbine Want to build a wind turbine for your home? I have gathered several PDFs for those who want to build there own wind turbines and have links to them at the bottom of this post. They cover all types of wind turbines and issues that you may run in to such as wind speeds and noise. From reading these my self I have found that the Hi-VAWT takes all into consideration and is easy to replicate. In VENTURI horizontal axis Wind Turbines wind turbines the blades rotate and describe a circular surface.
