Everything you always wanted to know about green homes: An interview with Avrim Topel

Green buildings have never been so popular, at least when it comes to public policy. Looking at the stimulus plan you see how a concept that until lately was relatively marginal suddenly becomes a significant policy tool, which is expected to stimulate the economy, lower energy consumption, create jobs and support the environment, all the same time.
But what does a green building or a green home actually means? well, for most of us it would be difficult to get into specifics as so few had the chance to experience it personally, but for Avrim and Vicki Topel know the answers.
They have built a green home (LEED Silver Certified) at Kennett Square, PA and they’re sharing their story in a new book entitled “Green Beginnings: The Story of How We Built Our Green & Sustainable Home“. This book is a valuable book for anyone interested in going green or building a green home. It is also part of a greater effort of the Topel’s experience to share their experience with others, which includes tours in the house and a documentary video. And last but not least, as we reported earlier, Eco-Libris is collaborating with the authors to plant trees for the copies sold of the book.
As we wanted to learn more about the authors’ experience and their book, we asked Avrim Topel to join us for an interview.

Granite Showrooms Continue Selling Radioactive Granite
Posted in March 27th, 2009
Last fall, Cathy Woods removed her Jupurana Bordeaux granite counters because they were radioactive. She did not want uranium ore in her kitchen, and she did not want to breathe the radon gas emitted by the granite.
The showroom that sold Cathy her granite had a new shipment of Jupurana Bordeaux around the same time. That stone was more radioactive than the granite they sold Cathy. However, sales staff told customers their granite was no more radioactive than soil or water.

Scientists from GIT (Georgia Institute of Technology) have invented a new solar cell surface treatment that could be applied to existing solar cells technology, and that could boost the light absorption into the cell. It also has self-cleaning capabilities.
