Beleaguered biofuel maker Kior has managed to close the financing it was hoping from investor Vinod Khosla, which will keep the company from temporarily defaulting on its loans and filing for bankruptcy. In a filing, Kior says it will be getting monthly installments of $5 million (via a note purchase agreement) for up to $25 million. This could keep Kior afloat for a few months, but the company will need to raise much more project financing to move toward commercialization again. Kior’s stock is up over 50 percent on the news to $0.90 per share in morning trading. Check out my recent piece on the story of Kior.

Startup OneRoof Energy has closed another funding round of $31.5 million, according to a filing. Launched in 2011 and based in San Diego, Calif., OneRoof teams up with roofers and electricians to sell rooftop solar systems and financing products (like leases). The company has also raised funding from Morgan Stanley, Black Coral Capital’s energy fund and Korean power company Hanwha. The market for solar panel systems is growing dramatically in the U.S.
This $31.5 million is a subset of OneRoof Energy’s recent reverse merger with Carlaw Capital IV, a Canadian capital pool company, with total proceeds of around 50 million Canadian dollars. The $31.5 million is the portion of shares purchased by U.S. investors.

Is it hot in here? You might want to consider checking out the Wi-Fi enabled Aros connected air conditioning unit from GE and Quirky that will learn your preferences over time and cool your room without your input. The product will be out in May, and is part of the two companies’ connected devices partnership. The AC unit will work with the Wink app that operates a connected egg carton, a clock and other gizmos. At $300 for 8,000 BTUs it’s a bit pricier than a dumb system, but that’s how the internet of things works today.
