WellDog, OrionSolar, Micro Power Electronics

• WellDog, which has a number of technological solutions for natural gas extraction and carbon sequestration, announced a $6.5M Series D. The round included new investors Axiom Venture Partners, Kozel Energy and Yellowstone Energy Ventures, as well as existing investors EnerTech and Prospector Energy Capital.

• Israeli solar startup OrionSolar, which is developing dye cell PV, took in $1M from 21Ventures. This builds upon approximately $800k in earlier funding from 21Ventures and Incentive, an Israeli incubator group. According to the article describing the transaction, OrionSolar is targeting solar cells with costs under $1 per peak watt.

• Venture investors don't usually do buyouts from each other, so the story around Micro Power Electronics (battery technology) is an interesting one.
