Suck it up: an unorthodox climate solution

A machine to capture CO2 from the air

Nothing anyone is doing has accomplished anything meaningful to prevent climate change.

Sorry to be so blunt about it, but it’s true. Greenhouse gas emissions keep rising, hitting record levels despite the CFL bulb, the Prius, EcoMagination, solar and wind power,  the EU’s carbon-trading scheme, etc.  Nice tries don’t matter to the atmosphere.

The only thing that’s curbed carbon dioxide pollution on a scale that’s meaningful is the global recession.

This is why—unless and until scientists discover a breakthrough in clean energy or political leaders impose a global fossil-fuel tax or carbon emissions cap—we need to thing seriously about geoengineering.

A good place to start is with a recent report from the GAO, Congress’s research arm, called Climate Engineering: Technical Status, Future Directors and Potential Responses. It offers solid information and glimmers of optimism for those of us looking for a way out of the climate crisis. [click to continue...]

Kilimanjaro Energy: towering ambitions

Mount Kilimanjaro

Over the last decade, Nathaniel “Ned” David, a Harvard and Berkeley-trained PhD., has co-founded five technology companies that have collectively raised more than $700 million in financing. One, Syrrx, made a diabetes drug. A second, Achaogen, is developing a potent antibiotic. A third, Kythera Biopharmaceuticals, a pioneer in the field of  “aesthetic medicine,” is working on an injectable drug that will reduce localized fat–no more double chins!–and it was his experience there that led Ned into the world of clean energy and climate change.

There’s nothing wrong with helping people to look better, he told me when we met recently, but it wasn’t enough: “I was feeling a little ennui around what I was doing.” His son, Magellan, had just been born. “I suddenly had this desire to work on something of great moral urgency,” he said.

That’s no longer an issue. Ned, who is a boyish 43, helped start Sapphire Energy, an algae company, on whose board he still sits, and last fall he became the president of an audacious San Francisco-based startup called Kilimanjaro Energy. It goal? To harvest CO2 from the atmosphere and use it to make transportation fuels with a much lower carbon footprint than gasoline or diesel.

The name of the company says it all:  “We’re going to try to make fuels, while simultaneously saving the snows of Kilimanjaro,” Ned says. [click to continue...]
