Counting the Cost of Water

On September 23, 2008, in Blog, by Paul O`Callaghan

So right now a hydrogen fuel cell car, is most likely still ultimately reliant on a fossil fuel source, natural gas, to provide the […]

Whiskey’s for drinkin’, water’s for investing in

On July 29, 2008, in Blog, by Paul O`Callaghan

Last week I put out the idea that we were approaching a tipping point in water re-use. There were a few other headlines this week which support that. For one thing California’s second largest reservoir is now ‘at its lowest level in 30 years’. Last Monday the California Department of Water Resources Director, Lester Snow, […]

GE: Doing Cleantech The Right Way

On March 8, 2008, in Blog, by Neal Dikeman

I have long had a respect for GE (NYSE:GE), and how it runs its business. In cleantech, I am very, very jealous. They have made themselves into the company to beat. Whether by plan, luck, or simply applying sound business discipline, GE has made itself into a top 3 global cleantech player no matter happens. […]
