While water covers 73% of the earth’s surface, clean water is, in many parts of the world, a scarce and expensive resource, and is increasingly becoming more scarce and more expensive. It is common in the eastern and central parts of the US, however, even here we experience water shortages. Frakking, coal processing, cooling nuclear power plants, and other industrial processes require clean water, and produce dirty water, and water shortages are predicted in 36 states over the next 5 years.

Yet water is in the air. It’s easier to pull water out of a river or a stream, or even out of the ground, where it exists in the liquid state, than to condense water vapor out of the air, but this is about to change. And water vapor in the air is cleaner than water on the ground.

The Vapour Inc Pure Water Genie ™ condenses water out of the air, and uses about 1 kwh per gallon, depending on humidity and air temperature. The units come in various sizes for personal or office applications to embassy scale sizes.

My friends at Vapour Inc, call it the “Pure Water Genie.” I would call it a “Cloud Machine,” or a “Box of Rain.”

Consider the American Embassy in Damascus, or Tehran, or a military base in Afghanistan. The Vapour Pure Water Genie is a source of pure water in hostile territory. If the American Embassy in Tehran had it’s own discrete and independent water supply back in 1979, our military could have been better able to secure the site. If remote military bases in various operating theaters have their own discrete and independent water supplies, then we don’t have to allocate resources to move water in hostile territory; our logistics positions are stronger. If we can pull water out of thick air, we don’t need to burn fuel or risk lives transporting it. If it’s coupled with a solar energy system then our embassies we don’t need fuel for generators in countries like Egypt, Iraq, Syria, Pakistan, Russia and China, which are either unstable, potentially hostile, have limited supplies of clean water, an unstable energy supply and distribution system.

The Vapour Genie uses electricity to pull water out of air without plastic and fuel used to bottle and transport bottled water. The water is chemical-free, with purity second only to distillation. This is unmatched by bottled water, and in some cases tap water. The six-stage filtration includes: Sediment, Sterilize, Carbon Block, TCR, UF, UV.  As fuel prices go up, so will the cost of transporting bottled water. As the costs of “disposing” and recycling plastics increases, so will the cost of bottled water. But while fuel prices and plastic recycling costs will go up, solar energy systems will be stable or drop due to advances in engineering. (See my post from Dec. 17, 2011, “Moore’s Law Applied to Solar Power,” here.)

The Pure Water Genies perform optimally in 70% to 80% humidity and temperatures between 75 F and 84 F (24 C and 29 C). We can’t control ambient humidity, but we can control temperature. In Kabul, Afghanistan, for example, in a controlled room with 78 F, the humidity will range from 33% in August to 77% in February. The Water Genie 5000 will produce 600 liters per day in August and 4650 liters per day in February.

These could replace water coolers in offices across the United States – and according to John at Vapour Inc., there are 12 million today.  And these could provide a secure water supply for our embassies and for service personnel on missions around the world.

Solar flashlights on sale at Sierra Trading Post

Sierra Trading Post has solar-powered LED flashlights on sale for $7.96.I believe this is identical to a flashlight I’ve been testing and using and it’s pretty impressive – if kept on a windowsill – or exposed to artificial interior light – all day, it runs for at least a couple of hours.

And it’s got a clever design feature, which reduces the risk of accidentally turning on the light: the button needs to be depressed twiceto be turned on. That is, the switch is set to OFF, OFF, ON. If you didn’t know this, you’d likely find that it worked on your second try to turn it on.

Link to product page. We can think of two ways this light might be improved – (1) by adding photoluminescent (“glow in the dark”) material to the exterior, (2) adding reflective material, ideally Reflexite, to the exterior. A combination of both – and a bright color – would make it easily findable in the dark – when you’re likely to want it.

I’ve been keeping mine on the windowsill; be advised that these are seconds – because of minor cosmetic blemishes.

This seems a useful household emergency tool; possibly a good addition to a go-bag – but one wouldn’t want to store it in a go-bag, because of the charge. And it’s too big for a purse/keychain flashlight. However, they might be ideally placed one to a windowsill – or across from mirrors which get a steady exposure to light, or under a skylight.

Obama In Strasbourg, On Sustainability

At the “Town Hall” meeting in Strasbourg, France, April 3, 2009,  (Washington Post, LA Times, NY Times, White House.gov, NY Times Video)   President Obama spoke intelligently and well. FRANCE NATO OBAMA SARKOZY

He summed up the challenges we face:

We also know that the pollution from cars in Boston or from factories in Beijing are melting the ice caps in the Arctic, and that that will disrupt weather patterns everywhere. The terrorists who struck in London and New York plotted in distant caves and simple apartments much closer to your home. And the reckless speculation of bankers that has now fueled a global economic downturn that’s inflicting pain on workers and families — is happening everywhere, all across the globe.

President Obama also made very strong statements on “Sustainability” and “Globalization.”

Toyota promises plugin-hybrid by 2010

Toyota promises plugin-hybrid by 2010, according to Chuck Squatriglia on Wired’s Autopia:

It’s no secret Toyota’s been working on a plug-in hybrid to compete against the forthcoming Chevrolet Volt, but Wednesday’s announcement sets a firm deadline and makes it clear Toyota has no plans of ceding the green mantle to General Motors. It also underscores how quickly the race to build a viable mass-market electric car is heating up.

The company’s ambitious “low-carbon” agenda

includes cranking out 1 million hybrids a year and eventually offering hybrid versions of every model it sells. In the short-term, Toyota says it will produce more fuel efficient gasoline and diesel engines and push alternative fuels like cellulosic ethanol and biodiesel. It’s also pumping big money into lithium-ion batteries. With fuel prices going through the roof and auto sales going through the floor

because of it, Toyota president Katsuaki Watanabe says the auto industry has no choice but to move beyond petroleum.

“Without focusing on measures to address global warming and energy issues, there can be no future for our auto business,” he told reporters in Tokyo, adding, “Our view is that oil production will peak in the near future. We need to develop power train(s) for alternative energy sources.”

Watanabe’s reference to peak oil echoes that of GM CEO Rick Wagoner, who in explaining the company’s decision to shut down four truck factories said rising fuel prices and mounting demand for efficient cars are “structural, not cyclical.” In other words, the two biggest automakers in the world realize petroleum’s days are numbered

Architect Sheila Kennedy: "It’s curtains"

Architect Sheila Kennedy has, with her colleagues (whose names we don’t know, hence no attribution) designed The Soft House; Jorge Chapa at Inhabitat has an excellent post on Kennedy’s prototype house whose solar-collecting curtains would produce 16KWH. We strongly recommend you read Chapa’s post – and that you check in regularly at Inhabitat.

Given our concern with worst-case scenarios – and preventing them – this technological use could go far in prevention by producing more power cleanly and locally. But we want to see rugged and waterproof textile uses for tents and canopies and emergency shelters and sails – consider the possibility of transporting the equivalent of a circus tent to the site of a disaster or power failure – as contrasted to the transportation of heavy petroleum-consuming generators – or solid photovoltaic panels or turbines.

One last thought: Kennedy’s design, we suspect, likely does more than produce energy: it probably acts as a cooling mechanism, preventing or mitigating the effects of a heat emergency.

NanoTechWire has a short interview with Sheila Kennedy here.

J.C. Winnie/After Gutenberg – replacing transportation fuel with renewables

The ever-methodical J.C. Winnie at After Gutenberg has an outline of how the United States could replace fossil fuels with renewables for transportation needs – and this without a large change in vehicle weight, use patterns, or increases in mass transportation. Add those, and we’d have a plan that would be not only environmentally more palatable, but would substantially increase environmental efficiency. From After Gutenberg:

Carbon dioxide (CO2) is the most important anthropogenic GHG; and, such anthropogenic emissions unequivocally contribute to

climate change. The rise of CO2 corresponds to

the rise in global temperature and loss of arctic ice mass. Annual carbon emissions grew by about 80% between 1970 and 2004. Coal-fired electric power plants comprise the single biggest source of CO2 emissions in the world. By and large, such admonishments are being ignored by U.S. policy-makers.

While a planetary engineer in Germany, Roland Moesl, envisions saving life as we know it on Planet Earth, a green pundit in America, David Roberts, describes the Syllogism of Doom. Of course, in Germany between 2000 and 2003 their installed PV capacity quadrupled. And, this was while Germany was becoming the world leader in wind development. It is way past time, ‘Merika, to start doing things right.

A good start would be “the most comprehensive and credible report released on wind power by a federal agency in a decade” (and studiously ignored by mainstream media), which indicates how we could achieve 20% wind power by 2030. Yes, 2030 is too late to stop using coal, but as many have observed, no single strategy will suffice. Switching sooner to electric vehicles, strong support for solar and wind energy development, conservation and improved efficiencies can make an earlier contribution than the delayers have programmed us to expect. The growing risk with peak oil is that in their search for alternative fuel, Americans will ignore much more catastrophic change brought on by anthropogenic emissions. The coal and corn zombies must be repulsed.

That’s just an excerpt. Read the rest of this persuasive analysis at Project Gutenberg.

And we’ll pose a question – we’re beginning to notice county and local impediments to renewable installation – and an absence of state mandates to require utilities to buy surplus power back at reasonable rates. If end users installing renewables in grid-tied systems are discouraged from building capacity in excess of their own use, we’re going to have problems.

One alternative is the setting up of local power coooperatives. But we’re leery of solutions that require lots of lawyers and incorporations. As Malcolm Gladwell points out in The Tipping Point, sometimes the tipping point is making things easy.
