" ... trying to develop industrial blood--a synthetic version of the enzyme that blood uses to capture CO2 ... best known chemistry for CO2 management ... "

"Current carbon capture approaches use chemicals ... system has to be huge and the process requires a pile of heat, which means a pile of energy and therefore a pile of cash. The cost of electricity from a coal-fired plant is projected to rise 80% in order to pay for a 90% reduction in CO2."

Yesterday I got the link inviting me to try it ... here are some of the details ... 

 hohm is a web application that develops a detailed "picture" of your home and its energy use using a very detailed series of questions.  Questions cover ... the direction the front of your home faces ... and includes details about all major systems  and about the number of windows and square footage of widows on each side of the house.  See graphic to the right for pictures of the categories of questions.

After filling out 75% of the questions I was able to get a list of "best ways to spend

50, 100, and 500 dollars".

So far I found hohm easy to use and informative ... and the initial Q & A took about 20 minutes.

One of the by-products of bio diesel production is glycerol (a.k.a. glycerine).  Now that bio-diesel is becoming more readily available glycerol is now being considered as an alternative to normal glycol based anti-freeze.

" ...in the (1920s & 30s) glycerin saw some usage, but because of higher cost and weaker freeze point depression, it was not competitive with ethylene glycol. Glycerin is a by-product of the manufacture of biodiesel ... large amount of glycerin generated from high volume usage of biodiesel fuel has resulted in this chemical becoming cost competitive with the glycols currently used in engine coolants. For this reason, and lower toxicity comparable to that of propylene glycol, glycerin deserves to be reconsidered as a base for antifreeze/coolant."

Further work may be needed but this would result is less toxic environmentally friendly anti freeze.

... "This revolutionary solar cell technology provides a platform for EMCORE's next generation photovoltaic products for space and terrestrial solar power applications. Solar cells built using IMM technology recently achieved world record conversion efficiency of 33% used in space, and it is anticipated that efficiency levels in the 42%-45% range will be achieved when adapted for use under the 500-1500X concentrated illumination, typical in terrestrial concentrator photovoltaic (CPV) systems. Once commercialized, the CPV systems that are powered with EMCORE's IMM based products will see a reduction in the cost of power generated by approximately 10% to 20%. EMCORE expects to commercialize this technology for both space and terrestrial applications in 2009. Developed in conjunction with the National Renewable Energy Laboratory (NREL) and the Vehicle Systems Directorate of the US Air Force Research Laboratory (AFRL), the IMM design is comprised of a novel combination of compound semiconductors that enables a superior response to the solar spectrum as compared to conventional multi-junction architecture. Due to its unique design, the IMM cell is approximately one fifteenth the thickness of the conventional multi-junction solar cell and will enable a new class of extremely lightweight, high-efficiency, and flexible solar arrays for space applications.

"Combining these two approaches appears to yield better solar cell materials than either one alone does, according to Jin Zhang, professor of chemistry at the University of California, Santa Cruz. Zhang led a team of researchers from California, Mexico, and China that created a thin film doped with nitrogen and sensitized with quantum dots. When tested, the new nanocomposite material performed better than predicted - as if the functioning of the whole material was greater than the sum of its two individual components. The resulting hybrid material offered a combination of advantages. Nitrogen doping allowed the material to absorb a broad range of light energy, including energy from the visible region of the electromagnetic spectrum. The quantum dots also enhanced visible light absorption and boosted the photocurrent and power conversion of the material. When compared with materials that were just doped with nitrogen or just embedded with cadmium selenide quantum dots, the nanocomposite showed higher performance ... " ...
