If you are in favor of renewable,  clean, or solar energy, please sign this petition for FIT/CLEAN Program, accessible at http://sunisthefuture.net/?page_id=1065 Thank you very much. We are at a critical juncture in human history when individual effort and participation in the transition into renewable energy age is desperately needed!  Your signature will be very meaningful in helping all earthlings!  For a summary of why we need to switch to power the earth with Wind-Water-Sunlight quickly, reasons are explained by Stanford Professor Mark Z. Jacobson at http://sunisthefuture.net/?m=20110731 There are more than sixteen episodes of discussions on FIT (Feed-In-Tariff/CLEAN Program) available at  http://sunisthefuture.net Please feel free to read/listen to them (type in feed-in-tariff in the search box at right).

Now, let’s take a look at an intriguing design by the University of Hawaii in Solar Decathlon 2011, hale pilihonua: hale (a built structure), pili (connection, to connect), honua (earth and land), the name of the house suggests the connection between the home and nature: in the Hawaiian poetic, a house is like a gourd that holds the necessity of life. What we do in the ocean affects the land, what we do on the land affects the ocean.  The design of the house is also deeply connected with the land through the element of the sun, wind, and water.  This connection promotes sustainability because the house functions in harmony with naturally available resources.  On the exterior there is 3-dimensional organic PV  louvre panel array, farther in is the fiber reinforced plastic skin covering elliptically shaped shell structure/cross section. The shell undulates from one end to the next, creating a space in the underbelly for mechanical equipments and interesting interior space by changing the height of the ceiling from one end of the house to the next.  There is the aerogel insulation (the lightest solid known to men that is 99.9% air, with an R value of 13 per inch.) Aerogel

is a manufactured material derived from a gel in which the liquid component of the gel has been replaced with a gas. The result is an extremely low-density solid, with a notable effectiveness as a thermal insulator. It is nicknamed frozen smoke, solid smokesolid air or blue smoke due to its translucent nature and the way light scatters in the material; however, it feels like expanded polystyrene (styrofoam) to the touch (compliment of wikipedia). With a budget of $250,00 limit, the design is broken up into six shell modules, individually assembled and connected at the site. Followed by installing the PV modules.  This marriage between the PV and solar thermal allows hale pilihonua to balance its energy with what has taken from the land. Now, please enjoy this contribution to the future of design from Hawaii–>
