Investments
Aurora Biofuels
Aurora BioFuels, Inc. is a renewable energy company exploring new sources of feedstock for the production of biofuels. In particular, Aurora utilizes microalgae to generate bio-oil, which can be converted into biofuels.
Boston-Power, Inc.
Boston-Power, Inc. is a lithium-ion battery technology company. The lithium-ion battery technology that powers the portable devices consumers rely upon (laptops, PDAs and mobile phones) has reached a critical point in its evolution. Consumer demand for longer-lasting batteries continues to rise. However, the industry's drive for higher performance and lower cost has come at the expense of quality, and ultimately, safety. Boston-Power has been able to produce lithium-ion battery technology with quality and safety that has dramatically improved while delivering performance levels never previously seen in the industry.
eSolar, Inc.
eSolar develops large utility-scale solar power plants to cleanly and cost-effectively generate electricity on a massive scale.
GreenVolts
GreenVolts was founded with the goal of making concentrating photovoltaic (CPV) technology as affordable and scalable as the fossil fuel alternatives. GreenVolts’ CPV solution is a state-of-the-art technology that achieves the world’s highest solar-to-electricity conversion efficiency through an innovative integration of optics and solar tracking.
