Nazava社の設立は、オランダのGuido van Hofwegen氏なくしてありえませんでした。Guido氏は、誰もがきれいな水を手に入れられるシンプルな解決策を模索してきました。2007年にGuido氏は、2004年のスマトラ沖地震の壊滅的な被害がいまだ残る、インドネシアのバンダアチェにオランダから妻とともに移り住み、すぐに、きれいな飲料水の確保が難しいことに気付きました。「1家庭で毎日ガロン（約4ℓ）の水を購入し、灯油ストーブ（もしくはガスストーブ）を使って水を煮沸するのには費用がかかります。水が手に入る水汲み場もありますが、その水質は悪く、そこから遠くに住む人々にとっては、自転車で水を運ぶのは一苦労です。」
For a company that has only been in existence for a little over a year, Nazava is already showing an outstanding record. It has sold a total of 20,000 ceramic water filters and has introduced 12 different product lines to give consumers a variety of options. It also operates 6 different store locations throughout Indonesia, where consumers can directly purchase water filters, and offers a delivery service to families who don’t live near stores.
At the same time when Indonesia faced an energy crisis due to the soaring price of gas and increasing scarcity of kerosene, a lecturer at Brawijaya University of Malang in East Java pondered his substantial, meaningful contributions to society. To turn his musings to reality, Dr. Muhammad Nurhuda, with background in theoretical physics, delved into renewable energy research in 2008 in the form of clean cooking stoves, using waste-based fuel and for usage in underprivileged communities in Indonesia.
Transportation of water is one of the most arduous—and often dangerous—tasks in the developing world. And now a simple solution, which may prove as significant as the invention of the wheel, is changing the way people in developing countries transport up to 50 liters (more than 13 gallons) of water for cooking, cleaning and drinking.
At night in Rwanda, kerosene lamps flicker and burn across the verdant landscape. By this light, families cook their evening meals, business continues apace and students crack into their books. But those living in close quarters to a burning kerosene lamp inhale an amount of smoke estimated to be equivalent to forty cigarettes per day.
Solantern is a company that knows a good idea when they see it. And when founder Joseph Nganga realized that solar battery and LED technology was mature enough to replace the costly and expensive kerosene lantern, he set out to use his experience in identifying quality lanterns, together with his knowledge of marketing and distribution, to address one of the most trenchant problems in the developing world—access to clean, affordable light.
