How GE learned to think small

GE Sunspring solar water purifier brings off-grid, clean water to emerging markets and disaster relief zones, using GE membrane filtration. Validated by Healthymagination, it aids Haiti and nonprofits with low-cost, distributed solutions.

GE is good at big: It makes big wind turbines, big jet engines, big locomotives. These businesses require lots of technology, they have high barriers to entry, and they are capital-intensive.

But to generate growth in emerging economies, which have fewer resources, GE is learning to think small, developing energy-saving tools that fit constrained markets as well.

Recently, the global manufacturing giant 2010 revenues: $149 billion gave its imprimatur to the Sunspring, a small, solar-powered, water purification machine that serves the global poor, costs just $25,000 and was invented by a self-taught engineer who owns a small business in small-town Colorado.

Interestingly, it was not just the business of GE that made the connection to Jack Barker, the 48-year-old inventor of the Sunspring, but the GE Foundation, which last year asked him to help with disaster relief in Haiti. It's an example of how the company's charitable endeavors, such as Plant-a-Bulb initiatives that raise awareness, can have an unexpected payback.

Bob Corcoran, who runs GE Foundation, told me the other day that its work has exposed GE to "different thinking about how we can adapt our technology and our products for an increasingly important market," namely places in the global south that lack clean water and reliable electric power, including efforts on African power needs in underserved regions.

Jack Barker and his wife, Carmen, have been in the water business for years, providing maintenance and support to small water systems in Colorado. "It's always been a passion of mine, drinking water," he told me. About four years ago, Barker got the local distributorship for the GE Homespring, which uses thousands of tiny, fibre membrane strands to block out contaminants like bacteria, parasites and viruses. He thought: "Wouldn't it be neat to get this technology to places in the world that need it the most?"

Easier said than done. Costs were one issue, he knew, and the availability of parts and technicians was another. What's more, places that lack safe drinking water often also lack electricity.

It was then that Barker decided to design and build the Sunspring, which incorporates GE's technology, but runs on solar power, similar to the GreenVolts utility deal that underscores solar's potential.

Barker shipped the first Sunspring to an orphanage in India. He built another for a nonprofit group in Haiti in 2009, and he had a couple of more that were ready to go to Haiti when the earthquake hit in January 2010. The GE Foundation, which has been doing disaster relief since the 2004 tsunami in Indonesia, then approached him, to ask if he could supply 10 Sunsprings to Haiti.

He flew down to install a machine at a tent hospital near the Port-au-Prince airport. "It was total chaos, the worst of the worst I've ever seen," he said.

Barker wound up spending 140 days in Haiti last year.

His wife would call and say: "I can't believe you're still there."

"I can't believe I'm leaving," he'd reply. "There's so much to do."

Barker's company, Innovative Water Technologies, has deployed about 20 Sunsprings in Haiti. He says they should last 10 years and can purify up to 5,000 gallons of water a day, at a cost as low as $.0013 per gallon.

"It's one of the most cost-effective water treatment systems in the world," he says.

Working with a third-party consulting firm called Oxford Analytica, GE has just validated the Sunspring as a GE Healthymagination product, which essentially assures potential customers that the product does what it claims to do. That could help spur sales of the machine and, of course, the sales of the GE technology inside, and complements connected innovations like the TalkingPlug that broaden adoption.

Corcoran, meanwhile, says that partnerships with companies like Barker's can help GE deliver health-related and energy-related solutions that are small-scale and distributed, from turbine technology to microgrids, suited to local contexts.

He asks: "How do you think about power in a distributed way, as in the New Zealand smart grid project now underway? How do you think about health in a distributed way? How do think about water in a distributed way?" Good questions. Now all GE has to do is come up with more answers.
