Stanford engineers set record for capturing and storing solar energy in hydrogen fuel | Stanford News

Stanford engineers set record for capturing and storing solar energy in hydrogen fuel | Stanford News | Sustainable Living Through Technology and Nature | Scoop.it
Solar energy has the potential to provide abundant power, but only if scientists solve two key issues: storing the energy for use at all hours, particularly at night, and making the technology more cost effective. Now an interdisciplinary team at Stanford has made significant strides toward solving the storage issue, demonstrating the most efficient means yet of storing electricity captured from sunlight in the form of chemical bonds. If the team can find a way of lowering the cost of their technology, they say it would be a huge step toward making solar power a viable alternative to current, more polluting energy sources.

Green Building Case Study: Oregon's Center for Health and Healing

Green Building Case Study: Oregon's Center for Health and Healing | Sustainable Living Through Technology and Nature | Scoop.it

The Center for Health and Healing at Oregon Health and Science University, a 400,000- square-foot, 16-story medical office building, was an ambitious project from the start.

Comprising physician practices, outpatient surgery, a wellness center, research labs, and educational space, it incorporates a host of sophisticated energy-efficiency measures, water-conserving technologies, and other green features in an effort to show what’s possible in the often conservative market of medical office buildings. Those ambitious goals made it an especially valuable target for a comprehensive building performance study that took place about two years after occupancy.

The study team deployed an occupant survey, analyzed utility bills, and compared the building’s performance to the goals that had been set for it.

Insulation

Insulation | Sustainable Living Through Technology and Nature | Scoop.it
Insulation in your home provides resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort. HOW INSULATION WORKS To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms — conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy. Most common insulation materials work by slowing conductive heat flow and — to a lesser extent — convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must face an air space. Regardless of the mechanism, heat flows from warmer to cooler until there is no longer a temperature difference. In your home, this means that in winter, heat flows directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors. Heat flow can also move indirectly through interior ceilings, walls, and floors — wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house. To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Properly insulating your home will decrease this heat flow by providing an effective resistance to the flow of heat. R-VALUES An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value — the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density. When calculating the R-value of a multilayered installation, add the R-values of the individual layers. Installing more insulation in your home increases the R-value and the resistance to heat flow. To determine how much insulation you need for your climate, consult a localinsulation contractor. The effectiveness of an insulation material’s resistance to heat flow also depends on how and where the insulation is installed. For example, insulation that is compressed will not provide its full rated R-value. The overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself because heat flows more readily through studs, joists, and other building materials, in a phenomenon known as thermal bridging. In addition, insulation that fills building cavities densely enough to reduce airflow can also reduce convective heat loss. Unlike traditional insulation materials, radiant barriers are highly reflective materials that re-emit radiant heat rather than absorbing it, reducing cooling loads. As such, a radiant barrier has no inherent R-value. Although it is possible to calculate an R-value for a specific radiant barrier or reflective insulation installation, the effectiveness of these systems lies in their ability to reduce heat gain by reflecting heat away from the living space. The amount of insulation or R-value you’ll need depends on your climate, type of heating and cooling system, and the part of the house you plan to insulate. To learn more, see our information on adding insulation to an existing house or insulating a new house. Also, remember that air sealing and moisture control are important to home energy efficiency, health, and comfort. TYPES OF INSULATION To choose the best insulation for your home from the many types of insulation on the market, you’ll need to know where you want or need to install the insulation, and what R-value you want the installation to achieve. Other considerations may include indoor air quality impacts, life cycle costs, recycled content, embodied energy, and ease of installation, especially if you plan to do the installation yourself. Some insulation strategies require professional installation, while homeowners can easily handle others. INSULATION MATERIALS Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and — to a lesser degree — convective heat flow in a building cavity. Rigid foam boards trap air or another gas to resist conductive heat flow. Highly reflective foils in radiant barriers and reflective insulation systems reflect radiant heat away from living spaces, making them particularly useful in cooling climates. Other less common materials such as cementitious and phenolic foams and vermiculite and perlite are also available.

Solar Wars Draw Millions in Cash in Threat to Rooftop Industry

Solar Wars Draw Millions in Cash in Threat to Rooftop Industry | Sustainable Living Through Technology and Nature | Scoop.it
“ There’s a war brewing over the future of rooftop solar, and Arizona is at ground zero. Pinnacle West Capital Corp., which owns the state’s largest utility, last week said it has formed a third-party group to support candidates for an elected state board that regulates their industry. The move promises to inject $1 million into a race in which SolarCity Corp., a rooftop solar provider, is already planning to spend $2 million though a nonprofit it supports, according to officials from the two groups.”

These Sky-High Balloons Could Generate More Power Than Solar Panels | Sustainable Living Through Technology and Nature | Scoop.it

For all the cost and efficiency improvements in solar panels in the last few years, all land-based photovoltaics have one serious Achilles Heel: performance is dependent on the weather. If clouds are in the way, even the best solar panels don't work that well.
That's why Jean-François Guillemoles wants to look above the clouds. A solar researcher from France, he's proposing floating solar balloons that potentially could generate three times as much power-per-foot as their terrestrial brethren. His design would also be able to store energy as well as generate power.
