Michael Crowley, a senior scientist with the Chemical and Biosciences Center, created an animated model of Cel7A, nature's primary enzyme for decaying plants. By visualizing the enzyme's process, Crowley and his co-workers hope to bioengineer a version that will accelerate the process of making simple sugars from woody plants and farm wastes that are easily converted into cellulosic ethanol. Cel7A is a vegetarian molecule that is nature's primary agent for decaying plants. Crowley, an NREL senior scientist, and his associates are modeling Cel7A in hopes of bioengineering a version that will accelerate the process of making cellulosic ethanol from woody plants and farm wastes. A breakthrough like this would enable biofuels to be produced more easily from abundant biomass wastes and could reduce our nation's dependence on foreign oil.
McKinsey, like virtually all efficiency and carbon reduction studies, has assessed potential contributions of individual technologies, but has not attempted to assess the much more powerful aspects of whole building integration approaches to net-zero homes and commercial buildings. Advanced design, construction, control and operations are wholly missing from this analysis – as well as from NEMS, MARKAL, and MINICAM modeling efforts. Also, it should be noted that for virtually all of the IPCC and DOE CCTP scenarios to “work” in stabilizing atmospheric carbon concentrations massive amounts of new efficiency is assumed to occur without explanation of the source of that new efficiency in terms of R&D, investment, and support infrastructure.
Upper Right : NREL designed and built a Net Zero Energy Habitat for Humanity House about 5 miles from the NREL campus. Over the two years that NREL monitored the building it actually produced 3000 kWh more than it used (accounting for gas use). Key energy features of the building are: a) Highly Insulated R-30 Walls and R-60 roof, b) passive solar window design, c) energy recovery ventilation system, e) 4kW PV array, f) Solar domestic hot water system backed up by an instantaneous gas water heater. Upper Middle : NREL has collaborated with industry to develop a number of Building Integrated PV (BIPV) systems that can work with shingle style roofs, standing seam metal roofs, and flat “built-up” roofs. NREL has also partnered with industry to develop a combined PV-Thermal system (shown on the house) that simultaneously cools the PV array, and preheats the solar thermal array providing electricity and hot water while reducing the roof area needed for the panels. Upper Right: NREL has collaborated with industry to produce a variety of evaporative and desiccant based coolers that are more efficient than vapor compression technology. NREL has also developed a revolutionary concept “DEVap” that combines desiccant and evaporative cooling in a single element making it possible to do highly efficient evaporative cooling anywhere in the country. Analysis for a DEVap unit in Phoenix showed 80% energy savings compared to a typical vapor compression air conditioner (even accounting for the 1 to 2 month humid monsoon period in the summer). Bottom Left: NREL has collaborated with industry to develop electrochromic windows that can be controlled to darken when the sun is not wanted, and lighten when the sun is beneficial. Bottom Middle : NREL has collaborated with industry partners to develop two low-cost polymer based solar hot water systems. The system in a box can be purchased at Home Depot and installed as a do-it-yourself project for about $1000. Bottom Right: NREL has developed building energy simulation and optimization tools that enable the most cost effective package of efficiency and renewable technologies to be determined for any given savings level, in any building type, in any climate. Other NREL developed tools assist developers to design energy efficient community layouts accounting for trees and other buildings.

Fly Ranch Geyser at fly Ranch Hot Springs, located in Hualapai Flat about 24 km north of Gerlach, Nevada (3 spouting mountains) Caption Geysers are the rarest fountains found in geothermal aresa. What makes them rare and distinguishes them from hot springs is that somewhere, usually near the surface in the plumbing system of a geyser, there are one or more constrictions. Expanding steam bubbles generated from the rising hot water build up behind these constrictions, ultimately squeezing through the narrow passageways and forcing the water above to overflow from the geyser.
