Dow Solar rolls out Solar Shingles in California and Texas Dow Solar is rolling out its new POWERHOUSE Solar Shingles in northern California and central Texas Image Gallery (5 images) Installing photovoltaic panels is certainly the most common method of generating solar power on a rooftop, and in fact many people might think it’s the only method. There is, however, an alternative – photovoltaic shingles. It makes sense, when you think about it ... why install weatherproof shingles and solar panels separately, if you could get one thing that combined both? View all “The DOW POWERHOUSE Solar Shingle utilizes CIGS-based (Copper Indium Gallium diSelenide) thin-film photovoltaic cells, which have the highest efficiency of available thin-film technologies,” a representative for Dow told us. Unlike the adobe-inspired curved Solé Power Tiles we’ve covered previously, the POWERHOUSE shingles are completely flat, so they can be worked into existing flat-shingled roofs.

Home Green...Easy Knit Produce Bag Green…can mean more than one thing. There is green the color. And green, as in environmentally friendly. Today I am combining those two meanings into one with the: I made my reusable produce bag out of an old knit T-shirt. And then I went crazy! It is really easy and requires very little sewing. So let’s get started shall we? 1.)You just take an old T-shirt and turn it inside out. I made some small, some large. Some using the existing T-shirt hem and some not. 2.)Sew with a straight stitch or a narrow zig zag all the way around. Or you can finish the edge with: A French seam. A zig-zag stitch or serged edge - my favorite way. Make the seam allowance much smaller - like 1/8 of an inch. Or fold the seam allowance over to one side and stitch all the way around. 3. )You can do this next part 2 ways: Option 1: Draw lines to help guide you when you cut slits. and snip, snip, snip…with the tips of your scissors. You want to stagger the cuts like so… Option 2: Using your rotary cutter… 4.) 5.) That’s it!
MIT stacks solar panels like pancakes, increases their power output by up to 20x What’s better than one pancake? A whole stack of pancakes! Using the same logic, a team of MIT researchers have stacked a bunch of photovoltaic solar cells together to produce up to 20 times the power output of conventional solar power installations. Normally I’m the first to drop my jaw in awe at MIT’s latest and greatest innovations, but this one really is a bit of a no-brainer. To combat this issue, MIT has built 3D stacks of photovoltaic cells. Squeezing more power out of low-light periods is a huge, huge deal.

Engineers Against Poverty Huerto Familiar – Deshidratadora – Cómo deshidratar « Felix Maocho El proceso de deshidratado concentra los nutrientes, con una baja pérdida de vitaminas, pues los productos nunca están expuestos a altas temperaturas, por ello a igualdad de peso, el poder alimenticio es muy superior al de los frutos frescos, aunque hay que tener en cuenta que igualmente son mucho más ricos en calorías, lo que hay que tener en cuenta a la hora de establecer dietas equilibradas. Por este motivo, los productos deshidratados son muy adecuados en situaciones donde el bajo peso de los alimentos sea esencial, como ocurrir a excursionistas y escaladores, o cuando se intenta abastecer de urgencia a poblaciones que han sufrido una tragedia, como a las víctimas de terremotos, o en campamentos de refugiados en zonas de dificil acceso. En estos casos, alimentos deshidratados envasados al vacío, pueden ser una dieta de subsistencia muy eficaz. La temperaturas de secado oscilan entre los 38 a 71° C, lo que garantiza la destrucción de bacterias y la inacción de las enzimas. Uvas pasas
Huerto Familiar – Deshidratador solar, I.- Construcción « Felix Maocho Por Felix Maocho Una forma de aprovechar los excedentes de las cosechas es utilizar uno de los múltiples medios de conserva que se han inventado para guardar alimentos sobrantes ede los momentos de abundancia, para los tiempos de escasez. Hoy nos centramos en la deshidratación, utilizando para ello los deshidratadores solares, unos aparatos poco conocidos en España, pero muy comunes desde muy antiguo en otros lugares, principalmente en Centroeuropa y Europa del Este. La deshidratación es una forma tradicional de conservar alimentos, que a diferencia de las conservas, utiliza temperaturas suaves, lo que permite conservar intactas muchas propiedades alimenticias de los productos frescos. Durante el secado, la temperaturas oscilan entre 40ºC y 70ªC, que destruye las bacterias y desactiva las encimas. Lo que se pretende es reducir la humedad de los productos por debajo del 15 % para hacerlos invulnerables al ataque de los hongos. Deshidratador solar Bandejas Cámara de secado Pedestal Cámara
