- Daylighting system developer Solatube raised an undisclosed amount of "mezzanine funding" from Praesidian Capital. Dow Jones' Clean Technology Investor pegged the round as a $6mm debt financing.
- According to PE Week Wire, Silicon Genesis Corp, a developer of engineered substrate process technology for the semiconductor, display, optoelectronics, and notably for kerf-free silicon wafers for solar markets, has raised a $23mm round of financing. From PEWW: "Backers include H&A Asia Pacific, Lake Street Capital, Riverside Management Group, Firsthand Technology Ventures, Convexa Capital Ventures and Spencer Energy AS. Silicon Genesis has raised over $117 million in total VC funding, but this represents its first round since a 2001 infusion of $35 million at a post-money valuation of approximately $166 million."
- Cleantech investors in the news: Here's a nice profile of the role being played by Chevron Technology Ventures.
AltEnergyStocks had a very good overview of the opportunities available in large-scale electricity storage... The WBCSD had a nice take on the opportunities and challenges of cellulosic ethanol... And a recent report suggests thin-film solar will be a $7.2B industry by 2015... Here's a good example of the kind of applications for distributed sensor networks that would have been useful to have put in place years ago ("If bridges are a priority", then let's take spending away from other critical infrastructure and energy tech development needs in order to monitor them? Umm, maybe it really shouldn't be either/or...)... Do business travelers care about being green?... "You will never drive a hydrogen car"... But if you drive a biodiesel car, the byproducts may have some useful applications as well... Nathanael Greene points us to the Daily Show's hilarious send-up of the Cape Wind controversy... So I guess the next logical step would be paying people to walk around (hat tip to Matt Lecar of Trinity Ventures for this one)... Finally, deus ex nucleara?
