I read an excellent article from the October 3, 2008 edition of the N.Y. Times Magazine about the world of budding renewable energy companies and the role and function of venture capital companies in supporting them in their efforts to commercialize products. The article provided four basic questions, the answers of which determine largely whether a small start-up company survives; “Can it be built? How hard is it to build it? And if you can build it, can other people build it just as well?”...and..."Will anyone buy it?”
