In The New York Times on Thursday, I wrote about Google Ventures funding a Southern California startup that is developing mobile biofuel refineries that will travel to the fuel source to process agricultural waste and other biomass:

Google Ventures has led a $20 million financing round in CoolPlanetBiofuels, a Southern California start-up that is developing mobile refineries to turn wood chips, agriculture waste and other biomass into biofuels.

CoolPlanetBiofuels, an 18-month-old company, has also attracted the attention of ConocoPhillips, GE Capital and NRG Energy, which participated in the financing round along with North Bridge Venture Partners.

CoolPlanetBiofuels declined to disclose the total capital that it had raised, but it noted that Google Ventures was a major participant in the series B round announced Thursday.

“We take biomass such as corncobs, yard clippings wood chips and fractionate that biomass into discrete gas streams,” said Mike Cheiky, CoolPlanetBiofuels’ chief executive and a longtime technology executive. “Those individual gas streams aren’t really useful by themselves, so we run them through catalytic conversion columns that convert them to useful fuels.”

One limitation of using biomass as a feedstock for biofuels has been the expense of trucking low-value waste long distances to a refinery. So CoolPlanetBiofuels plans to take the refineries to the fuel source by packaging its machines in tractor-trailers.

“Biomass cannot be transported very far because in raw form it has a very low energy content,” Mr. Cheiky said.

He said a typical refinery would consist of a cluster of tractor-trailers that can process 10 million gallons of fuel a year.

“There’s a very large market opportunity here with a lot of headroom for innovation,” said Bill Maris, Google Ventures’ managing director. “These are early days and this space won’t end up with a single winner but any progress Mike and CoolPlanet can make will have a profoundly positive impact on consumers, the industry and the world.”

So far CoolPlanetBiofuels has built a small pilot plant that is producing biofuel for evaluation by oil companies, Mr. Cheiky said. He declined to identify the companies, citing a confidentiality agreement. The company expects to have its first one-million gallon mobile refinery operating within a year.

In Wednesday’s New York Times, I write about a Google-backed startup that unveiled a new power conversion technology it claims will dramatically cut the energy consumption of motors, electronic gadgets and other devices:

A Southern California start-up backed by Google and prominent venture capital firms announced on Wednesday a technology it claimed could slash the electricity consumption of a wide range of devices like industrial motors, hybrid cars, computers and cellphones.

The result could be electric cars that drive farther without recharging, the disappearance of bricklike device chargers and solar panels that generate more electricity, according to the founders of Transphorm.

The company, based in Goleta, Calif., has developed a power conversion module that it says cuts energy waste by 90 percent. Currently, about 10 percent of the energy generated in the United States is lost as electricity because it is converted from alternating current to direct current and back, according to Umesh Mishra, Transphorm’s chief executive.

“That converts to hundreds of terawatts of energy loss,” said Mr. Mishra, a professor of electric and computer engineering at the University of California, Santa Barbara, during Transphorm’s unveiling at the Mountain View, Calif., offices of Google Ventures, the search giant’s investment arm. “We will save hundreds of terawatt hours when Transphorm’s technology is fully implemented, the equivalent of taking the West Coast off the grid.”

The four-year-old start-up has raised $38 million in funding from Google Ventures, Kleiner Perkins Caufield & Byers, Foundation Capital and Lux Capital to develop a new type of power conversion module based on gallium nitride, a compound used in LEDs. Google has yet to test Transphorm’s power module as the product hasn’t been available.

“The opportunity is to take 300 coal plants off grid effectively, said Randy Komisar, a partner at Kleiner Perkins.

Mr. Mishra said Transphorm had signed up customers like Yaskawa Electric Corporation, a Japanese maker of motors and industrial robots, and would introduce its first products in March.

Current conversion modules are based on silicon, a material that Mr. Mishra said was “running out of steam” in its ability to more efficiently convert power at high voltages.

He compared silicon-based power conversion modules to a dimmer switch that stayed warm even as it lowered the lights. A gallium nitride power conversion module is akin to a standard light switch that completely cuts the flow of electricity when turned off.

“Gallium nitride allows you to do that conversion without wasting energy,” said Mr. Mishra. “It can hold maximize voltage when off and minimizes loss.”
