. PV boilers. Slimme zonnestroom. Free Electric Bike - Billions in Change. Een uurtje op deze fiets geeft je huis genoeg stroom voor 24 uur. De oprichter en eigenaar van ‘s werelds best verkopende energie shot 5-Hour Energy, Manoj Bhargava, heeft aangegeven om 99 procent van zijn vermogen van om en nabij de 4 miljard dollar te spenderen aan het verbeteren van de wereld.
Verschillende onderzoeksteams werken in opdracht van Manoj aan oplossingen voor drie verschillende vraagstukken: die van elektriciteit, water en gezondheid. Het eerste resultaat is de Free Electric, een fiets waarmee je in een uurtje genoeg energie kunt opwekken om je huis 24 uur van stroom te voorzien. Hoewel ik me kan voorstellen dat er genoeg mensen in Nederland zijn die er graag eentje in huis zouden willen halen, zal Free Electric toch de grootste impact hebben in minder ontwikkelde landen. Stel je namelijk eens voor dat er dankzij gratis elektriciteit opeens honderden miljoenen extra mensen op onze wereld toegang krijgen tot internet, en alle kennis en opleidingsmogelijkheden die deze toegang met zich meebrengt.

How Much Can You Save With Solar Panels? Just Ask Google. If you’re considering solar power but aren’t quite sure it’s worth the expense, Google wants to point you in the right direction.
Tapping its trove of satellite imagery and the latest in artificial intelligence, the company is offering a new online service that will instantly estimate how much you’ll save with a roof full of solar panels. On Monday, the company unveiled Project Sunroof, a tool that calculates your home’s solar power potential using the same high-resolution aerial photos Google Earth uses to map the planet. Twee nieuwe werven: volg de bouw van de windparken in Zandvliet en Minderhout! Tryst Energy - Kickstarter: Light Energy. Voor de Wereld van Morgen. SolPad - The smart home solar solution is here. Solar energy rolls out like a carpet with groundbreaking Roll-Array photovoltaics. Solar power is easier to install than ever before thanks to the latest innovation: the Roll-Array.
John Hingley and his team at the renewable energy company Renovagen designed a high power PV array that rolls out like a carpet. This flexible and easy-to-transport instant microgrid has the capacity to bring alternative energy to places we never thought possible. Check out the video below to see it in action. HOW TO CHART THE SUN’S MOTION IN RELATION TO YOUR HOMESTEAD. Learn to track the sun before you design your home to determine the best orientation for it, as well as how to take advantage of the sun rays, because the position is also important for the passive cooling and heating of the house.
Understanding the sun’s motion relative to a site is an important aspect of a good permaculture design, as various elements like plants, animals and solar devices depend on sun for their functionality. A good appreciation of the earth’s rotation about its axis, its revolution around the sun and the consequences of these motions on the sun’s position and availability at a given location on the earth’s surface, is essential for maximizing plant productivity, harnessing maximum energy, minimizing energy usage and maintaining a comfortable indoor environment for humans and animals alike.

Bladeless, funnel-based wind turbine claims huge efficiency gains. Funny Looking Tower Generates 600% More Electrical Energy Than Traditional Wind Turbines.
The Sheerwind wind turbine promises to produce 6 times the electrical power than traditional wind turbines.
This funny looking wind tower acts like a funnel, directing the wind from any angle, down through a tube to a ground based turbine generator. The funneling of the wind through a narrow passage effectively creates a “jet effect” increasing the velocity of the wind, while lowering the pressure. A Material That Could Make Solar Power “Dirt Cheap” A new type of solar cell, made from a material that is dramatically cheaper to obtain and use than silicon, could generate as much power as today’s commodity solar cells.
Although the potential of the material is just starting to be understood, it has caught the attention of the world’s leading solar researchers, and several companies are already working to commercialize it. Researchers developing the technology say that it could lead to solar panels that cost just 10 to 20 cents per watt. Solar panels now typically cost about 75 cents a watt, and the U.S. Department of Energy says 50 cents per watt will allow solar power to compete with fossil fuel. In the past, solar researchers have been divided into two camps in their pursuit of cheaper solar power.
The new material may make it possible to get the best of both worlds—solar cells that are highly efficient but also cheap to make. “Between 2009 and 2012 there was only one paper. World record solar cell with 44.7% efficiency. The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells.
Surpassing competition after only over three years of research, and entering the roadmap at world class level, a new record efficiency of 44.7% was measured at a concentration of 297 suns. This indicates that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. How it Works. Watch this: Watch 3 actual turbines in action!
How I built an electricity producing wind turbine. Several years ago I bought some remote property in Arizona.
I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. Zoetrope-wind-turbine.pdf.
