Makani Power is an exciting start-up in California, with a team of sail makers and kite designers fronted by a MacArthur genious grant recipient and a World Cup windsurfer. They build what they refer to as super-kites, aimed at harnessing energy from high altitude winds, and have already successfully been able to generate enough power to supply five average households with one not-too-big kite. With millions of dollars from Godzilla Google, they are determined to tap in to a constant source of energy, and generate the cheapest and cleanest energy yet. Wait, what, an actual solution?

Water fluoridation has been advocated by the U.S. Department of Health, the World Health Organization, and, as an effect, dental associations and national health councils all over the world. It has been argued that fluoride is a nutrient mineral that is essential for human health, and the optimum concentration is just under one milligram per litre. The WHO claims that “Any public water supplies with fluoride levels below 0.1 mg/l (ranging up to 0.3 for cooler climates) need to be fluoridated with artificial fluoride.” Yet no evidence supports that fluoride is an essential nutrient for humans, or that it has any oral health benefits.
