We are thrilled to have Jurriaan Kamp, the founder of Ode Magazine, as our speaker in San Francisco this month. Kamp will discuss his thoughts on the power and need for optimism and solutions in our
current world, the role of media and specifically Ode in making a positive impact needed to create a sustainable world.
Ode’s mission is to publish stories about the people and ideas that are making a difference. The magazine for “intelligent optimists,” Ode reports on positive news in the areas of health, science, spirit, life, energy and business. Odemagazine.com is a vibrant community that connects readers from around the globe.
Jurriaan Kamp founded Ode Magazine in The Netherlands in 1995 with his wife, Helene de Puy. The magazine continues to thrive there and in 2007, Ode Magazine’s U.S. offices opened in the Bay Area.
Before founding Ode, Kamp was an editor, correspondent in South Asia and Chief Economics Editor at the Dutch daily newspaper NRC Handelsblad. He is the author of Small Change: How Fifty Dollars Changes the World and Because People Matter. Ode Magazine in the Netherlands recently published its 100th issue.
Please join us on Tuesday, September 28th for this amazing opportunity. To register for the event, click here.

As a an entrepreneurial problem-solver, I am very excited to learn about this group. Initially a Petroleum Engineer, transformed through the software industry and ultimately telecommunications, I am passionate about putting my technology know-how into growing sustainble businesses that are good corporate citizens. I have also had the good fortune to support non-profits and social ventures related to technology and entrepreneurship. I look forward to discovering others in the Dallas / Ft. Worth who are building sustainable businesses in creative ways.

Daily Cleantech: Aleksandr Stoletov and the First Solar Cell

On August 10, 1839, the eminent Russian physicist Aleksandr Grigorievich Stoletov is born (August 10, 1839-May 27, 1896). Stoletov built the first solar cell based on the outer photoelectric effect (discovered by Heinrich Hertz in 1887).
Born to the family of merchants in 1839, Alexander’s early life was one of study. He learned to read by the time he was four. Between 1849 and 1860 Stoletov studied physics and mathematics at Moscow State University, where he would become a teacher in 1865. As a professor worked to establish a physics laboratory for the school (which opened in 1872), so students would not have to go abroad to preform research. By his mid life, Stoletov was a world renown physicist, having developed a theory of “electro-techniques” and discovered important patterns in the magnetism of iron.
In 1888, he turned his attention to the photo effect, which was discovered by Hertz the year before. He built the first solar cell based on Hertz’s theory and earlier solar technology developed by Charles Fritts in 1883. Stoletov’s cell was more stable and reliable than the highly inefficient Fritts model. But it was not until Russell Ohl patented the idea of the junction semiconductor solar cell in 1946, that the modern day solar panel was born.
Additional Stoletov contributions to solar energy also includes the fact that solar cells decrease in efficiency as they age and the direct proportional link between the intensity of electromagnetic radiation acting on a metallic surface and the photocurrent induced by this radiation. This became known as Stoletov’s Law.
