Segway Creator Unveils His Next Act
Inventor Dean Kamen wants to put entrepreneurs to work bringing water and electricity to the world's poor.
( Business 2.0 Magazine editor-at-large )
San Francisco (Business 2.0) --- Dean Kamen, the engineer who invented the Segway, is puzzling over a new equation these days. An estimated 1.1 billion people in the world don't have access to clean drinking water, and an estimated 1.6 billion don't have electricity. Those figures add up to a big problem for the world --- and an equally big opportunity for entrepreneurs.
To solve the problem, he's invented two devices, each about the size of a washing machine that can provide much-needed power and clean water in rural villages.
"Eighty percent of all the diseases you could name would be wiped out if you just gave people clean water," says Kamen. "The water purifier makes 1,000 liters of clean water a day, and we don't care what goes into it. And the power generator makes a kilowatt off of anything that burns."
Light in the Darkness
Kamen is not alone in his quest. He's been joined by Iqbal Quadir, the founder of Grameen Phone, the largest cell phone company in Bangladesh. Last year, Quadir took prototypes of Kamen's power machines to two villages in his home country for a six-month field trial. That trial, which ended last September, sold Quadir on the technology.
So much so in fact that Quadir's startup, Cambridge, Mass.-based Emergence Energy, is negotiating with Kamen's Deka Research and Development to license the technology. Quadir then hopes to raise $30 million in venture capital to start producing the power machines. (With the exception of the Segway, which Kamen's own company sold, Kamen has typically licensed his inventions to others.)
The electric generator is powered by an easily-obtained local fuel: cow dung. Each machine continuously outputs a kilowatt of electricity. That may not sound like much, but it is enough to light 70 energy-efficient bulbs. As Kamen puts it, "If you judiciously use a kilowatt, each villager can have a nighttime."
A satellite picture of the earth at night shows swaths of darkness across Southeast Asia, the Middle East, and Africa. For the people living there, a simple light bulb would mean an extension of both their productivity and their leisure times.
The real invention here, though, may be the economic model that Kamen and Quadir hope to use to distribute the machines. It is fashioned after Grameen Phone's business, where village entrepreneurs (mostly women) are given micro-loans to purchase a cell phone and service. The women, in turn, charge other villagers to make calls.
"We have 200,000 rural entrepreneurs who are selling telephone services in their communities," notes Quadir. "The vision is to replicate that with electricity."
During the test in Bangladesh, Kamen's Stirling machines created three entrepreneurs in each village: one to run the machine and sell the electricity, one to collect dung from local farmers and sell it to the first entrepreneur, and a third to lease out light bulbs (and presumably, in the future, other appliances) to the villagers.
Kamen thinks the same approach can work with his water-cleaning machine, which he calls the Slingshot. While the Slingshot wasn't part of Quadir's trial in Bangladesh, Kamen thinks it can be distributed the same way. "In the 21st century, water will be delivered by an entrepreneur," he predicts.
The Slingshot works by taking in contaminated water --- even raw sewage --- and separating out the clean water by vaporizing it. It then shoots the remaining sludge back out a plastic tube. Kamen thinks it could be paired with the power machine and run off the other machine's waste heat.
Compared to building big power and water plants, Kamen's approach has the virtue of simplicity. He even created an instruction sheet to go with each Slingshot. It contains one step: Just add water, any water. Step two might be: add an entrepreneur.
"Not required are engineers, pipelines, epidemiologists, or microbiologists," says Kamen. "You don't need any -ologists. You don't need any building permits, bribery, or bureaucracies."
The Price of Freedom
Still, even if some of the technical challenges have been solved ("I know the technology works and I'd fall on my sword to prove it," insists Kamen), the economic challenges still loom.
Kamen's goal is to produce machines that cost $1,000 to $2,000 each. That's a far cry from the $100,000 that each hand-machined prototype cost to build.
Quadir is going to try and see if the machines can be produced economically by a factory in Bangladesh. If the numbers work out, not only does he think that distributing them in a decentralized fashion will be good business --- he also thinks it will be good public policy. Instead of putting up a 500-megawatt power plant in a developing country, he argues, it would be much better to place 500,000 one-kilowatt power plants in villages all over the place, because then you would create 500,000 entrepreneurs.
"Isn't that better for democracy?" Quadir asks. "We see a shortage of democracy in the world, and we are surprised. If you strengthen the economic hands of people, you will foster real democracy."
Lights, water, freedom. Now that's entrepreneurial.
US Patent Application 2004/0159536
Locally Powered Water Distillation System
( August 19, 2004 )
Dean Kamen, et al.
A system for distributed utilities including electrical power and water. A generation device is provided for converting an available resource to a desired utility; the resource may be water in which case the generator is a purifier for purifying untreated water, or alternatively, the generator may convert a fuel to electrical power. In either case, an input sensor is provided for measuring input to the generation device, while an output sensor is provided for measuring consumption of output from the generation device. The monitoring system has a controller for concatenating measured input and consumption of output on the basis of the input and output sensors. Measured parameters are telemetered to a remote site where utility generation and use are monitored and may also be controlled. At least a portion of the electrical power capacity of the electric generation unit may power a water purification unit such as a vapor compression distillation unit, and heat input of the electric generation unit may supply heat to the water purification unit.
