Driptech
In many poor farming areas, water is scarce and expensive. Drip irrigation would help farmers grow crops with only a fraction as much water as traditional methods require, though putting the systems in place has long been too costly. Driptech produces low-cost units to manufacture drip pipelines. According to the company, which has a pilot project in India, farmers who invest $20 in drip systems can grow $100 to $260 of vegetables a year—without waiting for rain.
