pink_dispatcher / CC BY-SA 2.0 The more people who get energy from clean sources like solar and wind, the better. That's an unambiguous truism at this point. Yet two primary factors prevent more folks from plugging into renewable power: Cost and access. Most people have neither a) the option to plug into a big, centralized wind farm or solar array, nor b) the financial resources to pay the upfront costs for distributed projects like rooftop solar. Which is why it's eminently important not just to continue investing in renewable technology to bring costs down, but to experiment with pricing systems that could make clean power far more affordable.

Simpa Networks | Our Solution
Simpa has initially introduced its “ pay-as-you-go ” pricing to household energy systems. Users pre-pay based on actual usage and each payment adds up towards the total purchase price of the solar home system. Consumers can send payments using a mobile phone. Once fully paid, the solar home system unlocks and delivers free electricity for the expected 10-year life of the product.

The Thermal Problem - Solar Fire Thermal Energy
Energy Infrastructure Attack Database (EIAD) Development Project - Tracking Energy Attacks
Background Contemporary debates on energy security involve numerous concerns – one of these concerns pertains to the security of energy infrastructure (EI) as key energy supplies such as oil and natural gas increasingly come from and/or transit through volatile regions complete with political instability, varied security, armed attacks by non-state actors (terrorist, insurgent or criminals, etc.), etc. Regardless of its form – such events have broad consequences. Indeed, recent reports on cyber attacks to energy information infrastructures bring to light another element of EI security.
New solar product captures up to 95 percent of light energy
Public release date: 16-May-2011 [ Print | E-mail | Share ] [ Close Window ] Contact: Steven Adams AdamsST@missouri.edu 573-882-8353 University of Missouri-Columbia Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.

Wo sind die Grenzen? Mit einem Demonstrator wollte das Team um Rolf Luchsinger , Leiter des «Center for Synergetic Structures» an der Empa, herausfinden, wo flugtechnisch gesehen die Knackpunkte sind, und ob ein Tensairity-Drachen allenfalls Vorteile gegenüber traditionellen Flugobjekten bieten würde. Zusammen mit einem Mitarbeiter, der Luft- und Raumfahrt studierte, entstand aus einer Vielzahl von Ideen zu Formen und Grösse des Drachens schliesslich eine Serie von Modellen mit verbesserter Aerodynamik und überzeugendem statischem Verhalten.
