13: Tap Water

'Forever chemicals' invade tap water 45% of U.S. tap water includes "forever chemicals." Also known as PFAS, or per- and polyfluorinated alkyl substance, they're used in everyday products such as fast-food containers, dental floss and shampoo because of their oil-proof, waterproof, heat-resistant and stain-resistant properties. However, they've also been linked to health issues like cancer and reduced fertility. Americans living in urban areas are more likely to have tap water with traces of PFAS than those in rural areas .

Ganymede Is Habitable

If you can travel, and if you can land, and if you can have a localized power source, maybe nuclear, you would have enough energy to melt the ice for water, and break that water into hydrogen and oxygen, for the oxygen. And you could live. The localized power source is key. Mining the asteroid belt for building material should be the new normal in a more sophisticated space travel era.

Happy World Water Day



If there is anything that is at the center of the globe's development agenda, it is clean water. Water also just so happens to be my favorite substance. I like to play with water. After I am done with the sink, you will likely see leftover splashes. Some people have thought it is because I am an untidy person.

There is something about the formlessness of water that gets me. Water in its formlessness reminds me of the human mind. Water is what the human mind should be, often is.

Bottled Water: Liquid Gold


BBC: Bottled water has become liquid gold: In the last 40 years the bottled water industry has gone from a business prospect that few took seriously, to a global industry worth billions of pounds. .... bottled water has become one of the biggest success stories in the modern food and beverage industry..... demand for bottle water has grown exponentially ..... "I think bottled water actually represents a kind of caricature of… the global economy.... "It provides people in the developed world with 20 or 30 varieties of something for which there is no actual variety." ... The Eau campaign was a marketing coup and sales went through the roof from 12 million bottles in 1980 to 152 million by the end of the decade. ...... "When you held a Perrier bottle up, it said something about yourself, it said you were sophisticated, you… understood what was happening in the world. ...... In an age of instant gratification, still water in portable bottles provided what people needed, exactly when they needed it. .... Strong, shatterproof and a highly valued form of polyester, PET is a by-product of the oil industry. ..... "Evian was sold as a beautiful person's drink" ..... Between 1990 and the turn of the century, global sales of Evian doubled from 50 billion to more than 100 billion litres a year. ..... a world where nearly a billion people have no access to clean water at all. ..... what bottled water is actually made of, oil and water; the world's two most precious resources, in one neat package.

If you can get a bottle of water for a buck, and a bottle of soda for a buck fifty, and the water is good for you, and the soda is bad for your health, then the water is a bargain, right? A lot of people don't think so.

Clean Water, Obesity

Technology Review: Clean Water For The Developing World: Cotton fabric treated with nano inks produces a water filter that's efficient and needs little power to work...... kills bacteria with electrical fields but uses just 20 percent of the power required by pressure-driven filters ..... At least a billion people have access only to water contaminated by pathogens or pollution. ..... There are two major chemical methods: adding chlorine to the water to kill the bacteria, or adding iron, which causes the bacteria to clump so it's easily removed. ..... Filtration, in contrast, is attractive because it's simple. .... other low-power solutions take too long or are too complex.

Obesity is to America what water is to the Global South. So much of health care costs would evaporate if most Americans lost weight. So many of the diseases in the Global South would go away if everyone had access to clean drinking water.

Some say we already have the knowledge for both and I am not so sure. One of my insights from volunteering for Obama 08 was that Americans don't socialize enough. They don't meet each other in person enough. Their overeating has a direct relationship to their emotional malnutrition.

It is not true we know all we need to know about clean water. Obviously the water cleaning technologies we have are not cheap enough, not simple enough. Obviously. There has to be relentless innovation to reach the masses.
