Dr Hoffman agrees that sanitation is insufficiently sexy. He says the technology behind his winning solar-powered toilet had been sitting on the shelf since he demonstrated it to NASA, America's space agency, in the early 1990s, for use on the International Space Station. "It is," as he puts it, "hard to get a scientific grant for treating faeces."
霍夫曼博士也认为卫生事业不是那么吸引人。他表示,他曾于1990年初将他的太阳能供能厕所向美国宇航局,美国国家航空和宇宙航行局进行展示以供他们在国际空间站中使用,但是这样的技术之后就被搁置了。他表示:"要在处理排泄物上得到科学基金是很难的。"
Even the Gates Foundation itself, which hands out around $3 billion each year, has so far devoted just $6.5m to its Reinventing The Toilet Challenge. But that will change as the project goes from conception to delivery. The foundation now intends to spend up to $80m a year on sanitation, an investment that the World Health Organisation estimates will produce a return of 900% in the form of social and economic benefits coming from increased productivity and reduced health care costs.
即使是盖茨基金会本身至今也尽投入了650万美元用于彻底改造厕所的挑战,而基金会每年的慈善基金花费在30亿元左右。但是这个项目从一个观念到实际交付,这样的的情况就会改观。当前,该基金会意欲每年在卫生上的投资加大至八千万美元。投资后,预计国际卫生组织会在社会和经济效益方面获得9倍的收益,不仅它的生产能力会提高,它的卫生保健成本也会下降。
