Well, think of Today show contributor Sloan Barnett as that friend. A mother of three, a dedicated consumer advocate, Sloan gives us a fast, simple, down-toearth primer on the ways our homes are making us sick, and what we can all do to transform them into the safe sanctuaries we want and need them to be.

Sloan exposes the toxic truth behind the household products we use every day -- from laundry detergent to toothpaste to lipstick. She explains how these and other seemingly benign stuff can harm us and our children. She offers an array of alternatives, and inspires us to see that we're never helpless: Every day, we have the power to make better, smarter, safer choices.

This profound and accessible book details how science is studying nature's best ideas to solve our toughest 21st–century problems.

If chaos theory transformed our view of the universe, biomimicry is transforming our life on Earth. Biomimicry is innovation inspired by nature – taking advantage of evolution's 3.8 billion years of R\'9126D since the first bacteria. Biomimics study nature's best ideas: photosynthesis, brain power, and shells – and adapt them for human use. They are revolutionising how we invent, compute, heal ourselves, harness energy, repair the environment, and feed the world.

Science writer and lecturer Janine Benyus names and explains this phenomenon. She takes us into the lab and out in the field with cutting–edge researchers as they stir vats of proteins to unleash their computing power; analyse how electrons zipping around a leaf cell convert sunlight into fuel in trillionths of a second; discover miracle drugs by watching what chimps eat when theyᱥ sick; study the hardy prairie as a model for low–maintenance agriculture; and more.

Producing electricity from the sun using photovoltaic (PV) systems has become a major industry worldwide. But designing, installing and maintaining such systems requires knowledge and training, and there have been few easily accessible, comprehensive guides to the subject.

Now, with Photovoltaics: Design and Installation Manual, a world-class solar energy training and education provider-Solar Energy International (SEI)-has made available the critical information to successfully design, install and maintain PV systems. The book contains an overview of photovoltaic electricity and a detailed description of PV system components, including PV modules, batteries, controllers and inverters. It also includes chapters on sizing photovoltaic systems, analyzing sites and installing PV systems, as well as detailed appendices on PV system maintenance, troubleshooting and solar insolation data for over 300 sites around the world. Used worldwide as the textbook in SEI's PV Design & Installation workshops, topics covered include:

The basics of solar electricity
PV applications and system components
Solar site analysis and mounting
Stand-alone and PV/generator hybrid system sizing
Utility-interactive PV systems
Component specification, system costs and economics
Case studies and safety issues

Photovoltaics guarantees that those wanting to learn the skills of tapping the sun's energy can do so with confidence.

Solar Energy International (SEI) has the nonprofit mission to respond to the need for renewable energy education. Based in Carbondale, Colorado, and active around the world, SEI is a link between people and renewable energy resources, providing information, education and training to people who want to shape a sustainable future. SEI is recognized by the National Board of Certified Energy Practitioners (NABCEP) as dedicated independent provider of PV training programs that may be used toward attaining PV certification. Also, SEI is recognized as an Accredited Institution to offer PV training by the Institute for Sustainable Power (ISP).
