在另外两个例子中,技术人员针对这样一个事实想出了解决之道:由于贫困,人们不得不用煤、木炭、柴火和动物粪便,来生火做饭和取暖。据估计,燃烧这些物质所产生的烟雾和灰尘每年导致全球200万人死亡,其中多数为妇女和儿童。
The Community Cooker from Kenya is a stove that burns waste at very high temperatures, above 800 degrees Celsius, to minimise noxious waste gases and ash. Reaching those temperatures was difficult, but the stove has been designed so that it can be built, maintained and repaired in the slums where it is being used.
肯尼亚的“社区炉灶(Community Cooker)是一种以极高的温度(超过800摄氏度)燃烧废物的炉子。高温燃烧能最大限度地减少有毒气体的排放和灰尘的产生。要达到这种高温很难,不过这样的炉子已经设计出来。贫民区居民可以搭建这样的炉子并自行维护和修理。如今,肯尼亚许多贫民区居民已经用上了这种炉子。
