Assessment of US Tap Water Quality

General Ripper in the movie “Dr. Strangelove” said he was afraid “precious bodily fluids” could be contaminated by the Communists, so he drank only distilled water or rainwater. He might have sounded a bit nutty at the time, but the latest report on US tap water might make the movie seem less comical. The Environmental Working Group released a report last month that had some disturbing data:

In an analysis of more than 22 million tap water quality tests, most of which were required under the federal Safe Drinking Water Act, EWG found that water suppliers across the U.S. detected 260 contaminants in water served to the public. One hundred forty-one (141) of these detected chemicals — more than half — are unregulated; public health officials have not set safety standards for these chemicals, even though millions drink them every day.
[…]
Our investigation reveals major gaps in our system of public health protections when it comes to tap water safety. Federal programs that allocate grants and low-cost loans to prevent water pollution and protect the rivers, streams, and groundwater that we drink are sorely underfunded.

When you consider how important clean water is to the national infrastructure, the data suggests serious shortcomings that threaten to undermine US security.

EPA Administrator Stephen Johnson, as quoted by Salon, called clean drinking water “a key ingredient to keeping people healthy and our economy strong.”

Hot Lawns

Just read an amusing article in the Guardian about using your lawn to heat your home, based on the concept of heat pumps.

With fossil fuels becoming alarmingly expensive, this environmentally friendly and low-cost alternative to gas central heating is finally coming into its own in the UK. It is incrediblyeffective, capable of achieving 400% efficiency – giving out more energy (typically 3 to 4 kilowatts) than the householder puts in to run it (typically 1KW). By comparison, an average gas boiler works at 90% efficiency at best.

According to Professor David Reay, of Heriot-Watt University, an expert on heat pumps, little can be said against them. Variants that extract heat from outside air perform less well in cold weather, just when the heat is needed most.

I thought the close of the article was insightful:

So if heat pumps are such a great idea, why haven’t they caught on before? “Gas has been cheap, and the British are capital-averse,” sighs Tony Bowen [president of the Heat Pumps Association, the UK trade body]. “As a nation, we are bad at investing in low long-term running costs.”

It goes far beyond the nation…but it is good to see the UK seeking less dependence on oil as well as more distributed/resiliant sources of energy.

Fiberlight

Himawari LightI think this is brilliant (pun intended). It reminds me of the concept of armored spaces that protect the inhabitants while retaining visual/light capabilities, but this adds in a component of also powering itself. Plain glass windows have been ok, but they clearly have drawbacks (ok, sometimes the puns just jump out). In this case the UV is blocked by walls, while a solar panel collects energy and glass fibers distribute the light. So, fiberlight (plus video) should provide a radical reduction in risks while maintaining many benefits from windows.

Wonder what Milton would have said about this fine use of talent to produce technology that might protect those who speak out in favor of a republic and against the supreme executive (e.g. he feared he “lost his light” because of writings like “the Tenure of Kings and Magistrates” and his support of Cromwell)…

When I Consider How My Light Is Spent
by John Milton (1608-1674)

    When I consider how my light is spent
         Ere half my days in this dark world and wide,
         And that one talent which is death to hide
         Lodged with me useless, though my soul more bent
    To serve therewith my Maker, and present
         My true account, lest he returning chide,
         "Doth God exact day-labour, light denied?"
         I fondly ask. But Patience, to prevent
    That murmur, soon replies: "God doth not need
         Either man's work or his own gifts: who best
         Bear his mild yoke, they serve him best. His state
    Is kingly; thousands at his bidding speed
         And post o'er land and ocean without rest:
         They also serve who only stand and wait."
