Donald O'Neal was working in Guatemala. He observed how the people were being harmed by the three-stone stoves they were using for cooking. Some people were burned and all the family suffered from the smoke. Don thought there must be a better way. He invented a stove made of concrete blocks. It had a vent to take the smoke outside. The women readily accepted the new stove. 110,000 of the ONIL stoves have been put in homes in Guatemala and Nicaragua. The people are healthier and happier.
