The CampStove 2 is a wood burner which uses no charcoal or liquid fuels to operate, using only wood for fires.
In the dusty khaki scrubland of South Africa’s inhospitable Northern Cape province, brightly polished mirrors flash light across the landscape as they rotate slowly to follow the sun, producing electricity for 80,000 homes. Continue reading… “The leapfrogging continent”
Fat consumption remains a concern among developing countries.
The extent of the obesity epidemic worldwide has been thrown into stark reality as a report from the Overseas Development Institute (ODI) puts the number of overweight and obese adults in developing countries at more than 900 million.
By rejecting patent applications, developing countries have kept down the costs of much-needed medications.
Gleevec, a leukemia drug, costs $70,000 per year in the United States, but only costs $2,500 in India. Why does that drug cost so much more in the U.S.?
“7 billion and counting”
The global population is expected to surpass 7 billion later this year, up from 6 billion in 1999. An estimated 2.3 billion more people will be added—nearly as many as inhabited the planet as recently as 1950 between now and 2050. The population will reach 10.1 billion in 2100 according to new estimates from the Population Division of the Department of Economic and Social Affairs of the United Nations.
The first practical artificial leaf shows promise as an inexpensive source of electricity for homes in developing countries.
Scientists debut development of the first practical artificial leaf, one of the milestones in the drive for sustainable energy. The scientists described an advanced solar cell the size of a poker card at the 241st National Meeting of the American Chemical Society. The solar cell mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.
600 million adolescent girls living in poverty in the developing world are the most likely agents of change
The treatment of girls in developing countries is a huge, and perhaps the biggest, problem in development.
In the remote communities in Kenya the plight of girls is so moving. A 13-year-old girl with a baby on her back, who is helping her 60-year-old husband tend goats. Female circumcision (mutilation of girls) is common practice and a standard procedure during puberty. Girls are married right after puberty often to much older men. Girls are less likely to be educated and trafficking in women is rampant.
The heat source is a pair of headlights. A car door alarm signals emergencies. An auto air filter and fan provide climate control. But this contraption has nothing to do with transportation. It is a sturdy, low-cost incubator, designed to keep vulnerable newborns warm during the first fragile days of life.
A research team at Stanford has developed a refrigeration device the size of a thermos. What’s interesting is that it uses no electricity. Zip. Zero. Nada. Zilch. Instead, it contains some kind of coolant that becomes cold when it’s exposed to heat.
