冠军厕所也更为智能。它是由加州理工学院的迈克尔·霍夫曼开发的,并未它的开发者赚入了10万美元的一等奖奖金。霍夫曼博士的厕所是由太阳能电池板为一个电化学系统供能的。这样一来会产生两种物质:一种是氢气,另一种是化合物能氧化尿液中的盐分,产生氯。它能产生一种温和的消毒液来冲洗厕所。而氢气则能够被用来烹饪或给燃料电池充电产生电能。而整个过程产生的固体残渣则可以用做化肥。
The Gates Foundation will now pay for prototypes to be tested in the field, probably of all three winners and possibly of some other ideas, and Mr Gates hopes that the foundation's reinvented toilets will start being deployed for real in as little as two years. They will thus be able to contribute to achieving what is the most off-track of the United Nations' Millennium Development Goals, to halve by 2017 the proportion of people without sustainable access to basic sanitation. As the chairman of the UN Secretary-General's Advisory Board on Water and Sanitation, the Prince of Orange, observes, "politicians and leaders worldwide don't like to be associated with toilets, even state-of-the-art toilets. This sanitation stigma distorts international and national development agendas."
现在,盖茨的基金会就会为这些技术雏形付以报酬来进行该领域的试验,这些技术雏形有可能是前三甲,也有可能是其他的设计。盖茨先生希望由基金会彻底改造的厕所会在两年内正式投产。他们也能因此为联合国千年发展目标做出最不寻常(最离经叛道?)的贡献,在2017年使不能持续享受基本卫生设备的人口减少一半。联合国秘书长顾问委员会水与卫生部主席奥伦治公评价道:"全世界的政治家和领导人并不愿意让自己和厕所联系在一起,即使是最先进的厕所。正是这样一种关于卫生的特性让国际和国家的发展计划都产生了扭曲。"
