Design Submission for the 2010 Land Art Generator Initiative Design Competition Artist’s descriptive text: CONCEPT OVERVIEW Artocos are folded shell structures that capture and combine solar energy and wind to generate power, create space to inhabit and contemplate the surrounding ecosystem, and make visible and audible environmental processes that shape our lives. Each piece is composed of a double layer wall oriented to the path of the sun. Internal walls are clad with dark-colored thin film photovoltaic modules. Air enters through grated air intake vents facing the predominant wind direction. Sunlight heats the air in the chamber between the walls generating a convection air current while activating the photov

PlanetSolar - The Largest Solar-Powered Vessel in the World Built at the Knierim Yacht Club in Kiel in northern Germany, PlanetSolar is a vessels powered by photovoltaic solar panels that cover about 500 square meters of the boat's surface, making the catamaran the biggest solar-powered vessel in the world. It is worth mentioning that the boat is 31m long and 15m wide and cost 18 million euros to make (about $24.4 million). The 60-ton PlanetSolar has an average speed of 8knots (9mph or 15km/h). The solar panels installed on the vessel will be able to collect 103.4kW of energy that will power the engine. It is expected to be launched waterside in March and the sea trials will take place between June and September. In 2011, Raphael Domjan, a 38 year old Swiss, together with Gerard d'Aboville from France, who is the first one to row the Atlantic Ocean, are going to take the solar-powered boat on a journey around the world. The goal is to show that it is possible

The Chief Problems To recapitulate, the principal challenges we face in confronting our transition from fossil fuels while living on a finite planet are (with links to earlier posts): The  growth paradigm must end . A finite world with finite resources will not continue to support growth. Fossil fuels enabled a growth explosion, but those days are closing out. Even futuristic energy sources  cook us  in mere centuries on a continued growth trajectory. Folks who think the solution is to  expand into space  can step off the train now, since my primary interest is in addressing  this  century’s problems. Adios, space-migos. Conventional  oil production will soon begin terminal decline . Our most important energy currency will no longer keep up with demand. This will quite possibly be accompanied by instability and loss of confidence in long-term growth, bringing damaging economic consequences. Alternatives do not stack up  to the practical perks of fossil fuels. We will not simply migr
