From today's featured article

Cathy Leslie, Executive Director of Engineers Without Borders-USA
In order to stay competitive, tomorrow's engineer will need to become more culturally savvy, as well as adept at implementing appropriate technologies. Capacity building is not about constructing a showcase engineering project. It's about coming up with practical, sustainable solutions that fit the environment, its people and the culture as well. (ASME)

Arcata Educational Farm
Organic farming is the form of agriculture that relies on crop rotation, compost, biological pest control, mechanical cultivation, and other techniques using natural processes, to maintain soil productivity and control pests. Organic farming excludes or strictly limits the use of synthetic fertilizers, pesticides, and livestock feed additives. Genetically modified organisms are excluded, and organic standards in Britain and Australia exclude engineered nanoparticles.

"Organic agriculture is a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. Organic agriculture combines tradition, innovation and science to benefit the shared environment and promote fair relationships and a good quality of life for all involved..." -- International Federation of Organic Agriculture Movements

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
