More Power To You

Electricity, like clean water, is a resource that's often taken for granted. But last summer, when blackouts struck much of the northeastern U.S., Ontario and Rome, consumers on two continents were given a painful reminder of just how fragile electricity supplies can be. The massive disruptions stranded commuters, defrosted freezers, shut down businesses and refocused attention on where most of the planet's power comes from: oil-and gas-fired generators and nuclear plants. These sources are not only plagued by creaky infrastructures, but they also pollute the environment and, many consumers feel, pose unacceptable health risks. Entrepreneurs like Lifton are trying to offer an alternative: clean energy from renewable resources that's plentiful and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and solar panels to give people power when and where they want it, free from dependence on local grids.
The search for alternative energy is nothing new, but the current crop of innovators is focusing on the long-elusive goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell which extracts electricity from the chemical reaction between oxygen and hydrogen has been around for about 150 years, though its commercial deployment did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo, where Japan's first hydrogen-fuel filling station opened in June; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fossil-fuel-free hydrogen economy by 2030.
When hydrogen and oxygen molecules combine, the reaction produces heat and water. Fuel cells harness this reaction to generate electricity. With the cell-phone and gadget market in mind, Medis has developed a fuel cell with cheap components that generates little heat and effortlessly eliminates waste water without resorting to energy-gobbling pumps. One of the attractions of fuel cells is that they can be big enough to run a factory or small enough to fit under the hood of a car. Medis' innovation is a type of micro fuel cell, a power source that's small enough to slip into your pocket. The Medis Power Pack a portable, wire-free mobile-phone recharger slated to be in shops by the end of next year will allow users to boot up their handsets whenever and wherever the need arises.
Phone fading fast at the football game? Just plug it into your Power Pack. About the size of a cigarette pack, the Power Pack will cost between $25 and $40 and last a year or more. The power comes from a disposable fuel cartridge that costs about a dollar and provides up to nine hours of phone use. Lifton sees enormous market potential, noting the 2 billion mobile phones estimated to be in use worldwide by 2007. New York based market researchers Allied Business Intelligence predicts that by 2011 the market for micro fuel cells will hit $2 billion to $3 billion; by 2013 the market for fuel cells big and small could reach $35 billion.
Hydrogenics, based in Mississauga, Ont., is also working to bring the fuel cell to market, though its products are big enough to power a car or a tank. Hydrogenics and General Motors (which owns about a quarter of the Canadian firm) are developing for the Army a fuel-cell-diesel hybrid engine for a new generation of 30,000 light tactical vehicles, which are used for battlefield surveillance and missile targeting. The military likes fuel cells because they can help free a vehicle from dependence on vulnerable supply lines, cut fuel consumption 20% and generate enough hydrogen to be self-sufficient in electrical power for up to five hours with the engine turned off. Fuel cells are also quieter and cooler than traditional portable generators and therefore are harder for the enemy to detect. "Aside from the need for additional power, we occasionally need to go into what's called silent watch," says an Army official at the Tank-Automotive and Armaments Command in Warren, Mich., who requested anonymity. Fuel cells last longer than the batteries that currently support such operations. The devices can also provide soldiers with water, a much needed resource, especially for those stationed in desert conditions. The water vapor from the fuel cells can be recycled for human consumption.
