A Battery That Lasts Forever

If it lives up to its billing, it will help accelerate the big green future. Companies and homeowners could pull the plug on their local utility by banking electricity from solar arrays and wind farms for use when the sun is not shining or the wind is not blowing. A 250-kilowatt battery system installed in a 40-foot container, for instance, could store solar energy from the rooftop arrays of a 40-home neighborhood for later use.

This magic box is called a vanadium redox flow battery. The heart of a flow battery are two electrolyte solutions — one positive, one negative — contained in separate tanks. When the solutions are pumped through a power cell containing a membrane, a chemical reaction takes place that generates electricity. When the process is reversed, the electrolyte stores energy.

The key component is vanadium, a naturally occurring element that can exist in positive and negative states, eliminating the contamination and degradation that occurs when two different elements are used to create a chemical reaction. Flow batteries are not as efficient as solid-state lithium-ion batteries. But unlike lithium-ion batteries that lose their capacity over time as they charge and discharge, the nontoxic electrolyte in a vanadium flow battery is endlessly reusable and never loses its efficiency.

In the beginning was the Word, and the Word choreographed an assembly of amino acids into an exquisite array of specific proteins. Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food.” In so doing God demonstrated a penchant for genomic writing, preceeded by an amazing series of prebiotic events, in a highly orchestrated presentation of evolutionary overcontrol.

Singapore’s Vertical-Farms

In Singapore, the challenge of feeding a growing population is pushing the concept of urban farming to new heights. A super-efficient vertical farming system is producing greens for 5 million residents.

“Can we supply enough food for everyone on the planet?” is a question plaguing leaders around the world. In Singapore SkyGreen offers one example of how this might be possible, “not just technically, but economically”. By increasing their food security while reducing the impact of food production on global climate change, SkyGreen is 10 times more productive per square foot than conventional farming.

A new means of generating electricity, one that utilizes bacteria to harness the energy of evaporating water, has been created by researchers from the Wyss Institute of Biologically Inspired Engineering at Harvard University.

The method could potentially be used to capture the energy released by ponds, harbors, and other bodies of water when the Sun warms them (causing evaporation), according to the researchers.

The newly created prototype generators work by harnessing the movement of a sheet of rubber that’s coated on one side with bacterial spores. As the sheet dries out, it bends, and as the humidity rises, it straightens out — the energy of these movements is then captured and used to drive a generator.

A soil bacterium called Bacillus subtilis wrinkles as it dries out like a grape becoming a raisin, forming a tough, dormant spore. Unlike raisins, which cannot re-form into grapes, spores can take on water and almost immediately restore themselves to their original shape.

Simply increasing the humidity from that of a dry, sunny day to a humid, misty one enabled the flexible, spore-coated plank to generate 1000 times as much force as human muscle, and at least 10 times as much as other materials engineers currently use to build actuators.

HVDC — High Voltage Direct Current

HVDC+valve+hallThe company that commissioned the world’s first 800 kilovolt UHVDC systems, the longest overhead HVDC link to go into commercial operation, and the world’s longest underwater and underground HVDC links, is now writing the next chapter in the evolution of this technology.

ABB has successfully designed and developed a hybrid DC breaker after years of research, functional testing, and simulation in the R&D laboratories. This breaker is a breakthrough that solves a technical challenge that has been unresolved for over a hundred years and was perhaps one of the main influencers in the ‘war of currents‘ outcome. The ‘hybrid’ breaker combines mechanical and power electronics switching that enables it to interrupt power flows equivalent to the output of a nuclear power station within 5 milliseconds – that’s as fast as a honey bee takes per flap of its wing – and more than 30 times faster than the reaction time of an Olympic 100-meter medalist to react to the starter’s gun!

The challenge was to do it ‘ultra-fast’ with minimal operational losses and this has been achieved by combining advanced ultrafast mechanical actuators with ABB’s inhouse semiconductor IGBT valve technologies or power electronics.

The new breaker is a ‘game changer’. It removes a significant stumbling block in the development of HVDC transmission grids. These grids will enable interconnection and load balancing between HVDC power superhighways integrating renewables and transporting bulk power across long distances with minimal losses. DC grids will enable sharing of resources like lines and converter stations that provides reliability and redundancy in a power network in an economically viable manner with minimal losses. It will enable the transmission system to maintain power flow even if there is a fault on one of the lines.

A Place of Warmth for a Continuously Productive Garden

walipiniAn affordable and effective alternative to glass greenhouses is the walipini (an Aymara Indian word for a “place of warmth”). Also known as an underground or pit greenhouse, it was first developed over 20 years ago for the cold mountainous regions of South America, this method allows growers to maintain a productive garden year-round, even in the coldest of climates.

A walipini combines the principles of passive solar heating with that of an earth-sheltered building. It utilizes nature’s resources to provide a warm, stable, well-lit environment for year-round vegetable production. Locating the growing area 6’- 8’ underground and capturing and storing daytime solar radiation are the most important principles in building a successful Walipini.

Reflections on Right Sizing

“The foxes have holes, and the birds of heaven have nests, but the Son of Man has nowhere to lay his head,” and so it is today for many of his followers. Despite all the warnings about the snares laid by moneylenders, despite the fact that gage mort is literally translated as a pledge to give up one’s life, millions have lost their homes through mortgage exploits, and their quality of life through the service of debt.

Along the river banks and across the plains, archaeologists have unearthed abundant evidence of human practicality. The long evolutionary struggle is depicted in dwell time as our earliest ancestors enjoy the inspiration of mountain vistas and the tranquility of peaceful valleys. They also experienced the terror of lightning strikes, glacial advances, animal attacks, seismic events and lava flows.

Homo Erectus is constantly mobile as he steadily progresses through his gift of ingenuity. He seeks shelter in caves, from overhanging ledges and under the brush. By learning to fashion materials, such as clay, wood, and stone, early humans were able to move down from the treetops and out from the hillside grottoes to create family huts. The home had begun to take shape as the most basic human institution.

Then, as the ice advanced, man again appropriates the most practical shelter that nature has to offer. The comforts of home give way to necessity as protection from the elements drives him ever onward in search of more suitable provisions.

Flash forward a million years or so and consider the plight of today’s homo-sapiens. Extreme weather, internecine wars, and raging wildfires all continue and conspire to keep a great humanity unsettled. The voids are filled, as if by reflex, with stunted vegetation, outgassing trailers, and tent cities as the most desirable solutions are put off time and again.

Bloated governments have generated burdensome regulations that allow us to live simply only if we are tucked into very small sheds or build our houses on wheels. These influences are literally driving us into dwellings that are too costly to build, too large to heat or cool, and too burdensome to maintain. Politicians pay lip service to sustainability while erecting huge barriers to those who are sincerely trying to leave the smallest of footprints.

The art of living large in a small abode is intriguing to the upwardly mobile as well as those who have chosen, or have been forced, to downsize. In the first case, squandering precious resources on mortgage interest is one of the fastest ways to become a wage slave. In the second case, the escape from a debtor’s prison is liberating in more ways than one can imagine.

This is not to say that there is no value in stress. Sometimes having a tough, recurring nut to crack is precisely what’s needed to cure the ease drifting soul. But, for the highly motivated, for those whose enthusiasm truly emanates from en-theos (God within), there are higher callings.

Supporting the same entitled barons of financial sophistry who brought us the Great Swindle, known by the less discerning among us as the “Great Recession,” is a form of self-imposed detention. It saddles us with excessive drag. In contrast, a pay-as-you-go strategy is easier than one might think.

The TV that once occupied floor space can now hang on the wall, a cabinet door, or the front of a drawer. The oversized washers and dryers that are pushed by appliance stores in the U.S. can be replaced by a single more energy efficient under-the-counter unit, readily available in Europe or at U.S. RV stores. These compact combo units employ the same drum for both washing and drying. The range hood over your stove can be replaced by a combination hood, microwave and convection oven to save even more space.

Ask yourself, how many burners do you really use on your stove? How about supplementing with a guest’s hotplate or slow-cooker for the pot-luck seasonal bash? Could you eliminate cooking odors, and greasy films on the walls, by using the outside grill more often? Do you really need a big oven, the one you justified with the Thanksgiving turkey, if you’re now frying it outside anyway?

There are so many ways to get right-sized. If you’re reading the periodicals biblically, and the bible periodically, then find out how many of your favorite periodicals are now online. And, if you want to read your bible more often, download it to your tablet or smart phone. Who knows, you may even decide you prefer the page-white backlit display to your itty-bitty-book-light.

Ever wonder how many linear feet of shelf space you could eliminate by converting your music and books to digital form? What about that shoebox full of receipts? You could adopt a new policy of scannin’ and pitchin’ em. Some stores will even email them to you. Hard discs are cheap and they don’t seem to get any heavier when you fill them up.

Over half of the people who live in tiny houses have no mortgage. That’s twice as many as the average U.S. homeowner. Owners of small houses have more savings than the average homeowner. 89% of tiny house people have less credit card debt and 65% have no credit card debt at all while such dwellers are also earning $478 more annually than the average American. They are also twice as likely to have a master’s degree. It just goes to prove that less debt service gives us more time for gainful pursuits.

Everyone seems to have a different definition, of what constitutes small, but generally a “tiny house” is less than ten percent the size and cost of the average sized house currently built in the USA. Once a 30 year mortgage at a 4.25% interest rate is added to the cost of a “standard” 2,100 square foot house that sells for $272,000 the bill is $481,704. The $23,000 owner built tiny house is often built entirely from savings that would otherwise yield an insultingly low rate of return.

The home is the crowning achievement of human kind. The Living Crown (TLC) project within Ascension University and the Aevia Group is focused on this basic institution of human progress. We believe home building should be the essence and at the center of all educational effort.

When the Lord asks: “Where is the place of my dwelling?” we look to his handiwork, and a universe of nurturing infrastructure, for the answer. We are still at the creative stage of homebuilding and seek an understanding of just how a minimalist structure can support maximum functionality.

We are actively developing a rapid-deployment, fit-for-purpose product line featuring houses that float, rooms reinforced with carbon fiber, and suites that filter air and water through a unique circulatory system. They will be energy efficient as well as energy independent depending on a wide array of options. They can be pressed into service as houseboats, in-law suites, safe-rooms, stand-alone cabins, and emergency shelters. They will look and feel like cozy cottages.

We are witnessing a ceaseless progression in refining what has become society’s veritable foundation. And our focus on evolving science, best practices, and continuous improvement is motivated by our passion for improving the home and ennobling the home life. Alignment and integration within the various Ascension University fields of study insures our academic initiatives are conditioned by real-world experience, and that the applied technology is always cutting edge. We are fully engaged in the virtuous cycle and you can be too!

The Pitch of a Solar Roof

The angle or pitch of your roof actually has less impact on solar panel performance than the direction it faces. In general, optimal production occurs when solar panels face south at a tilt equal to 30°. But what happens if your roof is flat? Lowering the tilt all the way down to 5° only decreases production by about 10%, regardless of where you live. The difference in production for steeper roofs is barely noticeable. Increasing the tilt from 30° to 40°, for example, results in a negligible decrease of about 1%.
Looking at data from six cities- Boston, Los Angeles, New York, Chicago, Philadelphia, and Washington, D.C., Energy Sage estimated the production levels generated at various tilt angles. They held the azimuth constant at 180° which in laymen’s terms means they always assumed that the roof faced directly south. What they found was consistent with their investigations into the effects of other variables.

Photo Voltaic Technology — The State of the Art

Science tells us that every square meter of the earth’s surface, when exposed to direct sunlight, receives about 1000 watts (1 kilowatt) of energy from the sun’s light. Depending on the angle of sunlight, which changes with the time of day, and the geographical location, the power of the sun’s light will be somewhat more or less than 1 kilowatt-hour per hour for every square meter of the earth’s surface exposed to the sun. Of this solar energy, about 523 watts is in the infra-red spectrum and the ultra-violet portion accounts for about 27 watts. The remaining 440 watts is produced by the octave comprising the visible range.
The chart pictured below depicts the current state of the art for Photovoltaic (PV) solar cells. PV research focuses on boosting solar cell conversion efficiencies, lowering the cost of solar cells, modules, and systems, and improving the reliability of PV components and systems. Accelerating the integration of PV technology is an essential part of global sustainability. Click on the chart reproduced here for a full size copy.

Building with Bioreactor Facade

An experimental apartment building in Hamburg, Germany is harnessing the power of the sun to generate power, but not in the way you expect. Photovoltaic cells are totally yesterdays news — the BIQ building gathers power using a bioreactor façade packed full of microalgae.

Large clear panels on the front of the building are where the microalgae are growing. These microscopic organisms behave like any other plant. They absorb sunlight, process carbon dioxide, and produce oxygen. The algae flourish in a regular cycle, with the mature plants being harvested on occasion.

The process is highly efficient as it results in no additional carbon output, and algae produce more biomass by area than any other plant. Any light that is not absorbed by the algae can be captured by the façade and used to directly heat water or air when it’s chilly out. Failing either of those immediate needs, the heat can be piped down into borehole heat exchangers (an 80-meter deep hole filled with brine) for later use.
