  • Beeswarm

    August is the first month of the "Beekeeping" Year

    What you need to know -- info from an ORSBA beekeeper

    August 12, 2017

    Thanks to Mike Standing, a local ORSBA beekeeper, for sharing this info.

    "As temps are on the increase, honey bees will swarm. Honey bees live in colonies. A swarm is a natural way that honey bees reproduce a new colony. When their current colony or home gets too small for them, they leave in a swarm to find a new place. What’s left in the old home is a brand new Queen and some younger workers to take care of the colony. The bees that left are now homeless! They are on the hunt for a new home. Sometimes they know where they are going. Most often they don’t quite know where their new home will be. While searching for their new home, sometimes they will land someplace to rest and regroup.

    The kinds of places they might land could be a branch from a tree, an overhang from a house, a streetlight, the side of a building, basically anywhere! When the honey bees left their old home, they stocked up all the honey they could carry in their honey sacs. They need this honey to help them get started in their new home. When the Bees are in this state they are non-aggressive! To fear them is only natural. It can be scary to look up and see a cloud of bees flying overhead... but do not worry. This is not a frenzy of bees on the war path out to attack everyone and everything in its path!

    The same goes if you are out for a walk and come upon a honey bee swarm that has landed someplace like a low hanging tree branch. Keep your distance; remember they are just resting until they can find a new home. Take all the pics you want, but don’t harass them! That’s a real good way to get stung!

    So what do you do if you come across a swarm? If you are in a highly populated area, the best thing to do is contact a local beekeeper by City to come and rescue the swarm."

    Natural Water Treatment in Western Washington County

    Fernhill Wetlands engineered from the water channel to the ground, up

    The restoration of Fernhill Wetlands has been a collaborative effort among the City of Forest Grove, Clean Water Services, and various engineering and design firms... built from the the water channel, up.

    When Clean Water Services (CWS), an Oregon utility, wanted to restore three former sewage lagoons associated with the Forest Grove Wastewater Treatment facility, they turned to Biohabitats to lead the design team. Though the ponds were occasionally visited for wildlife viewing, they held untapped ecological and recreational potential. Biohabitats’ design transformed the lagoons into a rich, 90-acre mosaic of riparian wetlands that provide natural wastewater treatment while also enhancing ecological function and recreational and educational opportunities along the Tualatin River floodplain.

    The restoration first involved draining the lagoons, drying more than 200,000 cubic yards of soil, and moving the soil to create precise contours and depths. Control structures were strategically placed to encourage the growth and establishment of 750,000 native wetland plants and 3.5 billion seeds that were planted for water quality and habitat. 180 logs and snags were anchored into place to provide wildlife habitat.

    The diverse habitats created by the restoration include open water, mudflat, emergent marsh, scrub-shrub, and upland areas that support wildlife. The enhanced habitat for waterfowl and shorebirds, has helped make the wetlands an important stopover site in the Pacific Flyway. Birds and wildlife have taken to the site, and human visitors are flocking to enjoy trail improvements, new outdoor classroom areas and views of the emerging wetlands.

    In terms of water quality, the wetlands reduce the temperature of the treated wastewater flowing into the Tualatin River, and serve to regenerate the complex systems of life and nutrients that exist in healthy waters. The treatment facility will treat 5-18 million gallons per day throughout the year. The project accommodates diurnal and seasonal variation in wetland system giving flexibility to provide important ecosystem functions. Wetland hydraulic control structures provide the CWS with the ability to manipulate water levels in the wetland cells to more closely mimic typical seasonal variations.

    By creating a wetland system that provides benefits in water quality, wildlife habitat, recreation, and education, CWS and Biohabitats are making a long-term investment in the health and resilience of the Tualatin River.

  • Forest-city-china

    This city is being designed to scrub the air of pollution

    Liuzhou Forest City

    China's approach to reversing climate change is firm and innovative.

    Covering an area of approximately 175 hectares along the Liuzhou River, Forest City will have offices, houses, hotels, hospitals, and schools that will be entirely covered by a total of 40,000 trees and close to a million plants, including over 100 species. It will be connected to the main city of Liuzhou by a rail line with electrical train cars.

    This will also be the first urban settlement in China that will be able to "generate its own renewable energy, increase biodiversity, and effectively reduce urban air pollution—which is a major challenge for present-day China."

    Barberry and Ticks

    You might not want this deceptively attractive plant in your yard if you have dogs or cats.

    A study by University of Connecticut shows that areas with the presence of Berberis thunbergii are more likely to have Lyme disease-carrying ticks:

    Williams recites the numbers. ”When we measure the presence of ticks carrying the Lyme spirochete (Borrelia burgdorferi) we find 120 infected ticks where Barberry is not contained, 40 ticks per acre where Barberry is contained, and only 10 infected ticks where there is no Barberry.”

  • Piezoelectrics

    Material can turn sunlight, heat and movement Into electricity -- all at once

    Extracting energy from multiple sources could help power wearable technology.

    A perovskite solid-solution that exhibits tunable bandgaps in the visible light energy range is showing promising material for light absorption and conversion applications,(solar energy harvesting and light sensing).

    Such a common ABO3–type perovskite structure, most widely used for ferroelectrics and piezoelectrics, enables the same solid-solution material to be used for the simultaneous harvesting or sensing of solar, kinetic, and thermal energies.

    These results are considered to be a significant improvement compared to those of other compositions which could be used for the same applications. The results pave the way for the development of hybrid energy harvesters/sensors, which can convert multiple energy sources into electrical energy simultaneously in the same material.

  • Biofuel_algae

    Biofuel-producing algae can now be farmed 10x faster than before

    New process moderates temperature of grow environment

    When the microalgae is first seeded, it’s kept at 15 degrees celsius, which makes it a solution. When it’s heated by just 7 degrees, it becomes a gelatinous mixture in which microalgae grows in clusters 10x larger than in the regular medium. Finally, it’s cooled again for harvesting, at which point it turns back into a solution, which can be separated using gravity.

    Cement that generates Light

    Carlos Rubio Ávalos of the UMSNH of Morelia, developed a cement with the capacity to absorb and irradiate light energy,

    The researcher claimed that the applications are very broad, and those which stand out most are for the architectural market: facades, swimming pools, bathrooms, kitchens, parking lots, etc. It would also be useful in road safety and road signs, in the energy sector, such as oil platforms, and anywhere you want to illuminate or mark spaces that don’t have access to electricity since it doesn’t require an electrical distribution system and is recharged only with light. The durability of light-emitting cement is estimated to be greater than 100 years thanks to its inorganic nature, and its material components are easily recyclable.

    Maybe it takes a forest to raise a tree

    "Why are trees such social beings? Why do they share food with their own species and sometimes even go so far as to nourish their competitors? The reasons are the same as for human communities: there are advantages to working together. A tree is not a forest. On its own, a tree cannot establish a consistent local climate. It is at the mercy of wind and weather. But together, many trees create an ecosystem that moderates extremes of heat and cold, stores a great deal of water, and generates a great deal of humidity. And in this protected environment, trees can live to be very old. To get to this point, the community must remain intact no matter what. If every tree were looking out only for itself, then quite a few of them would never reach old age. Regular fatalities would result in many large gaps in the tree canopy, which would make it easier for storms to get inside the forest and uproot more trees. The heat of summer would reach the forest floor and dry it out. Every tree would suffer.

    Every tree, therefore, is valuable to the community and worth keeping around for as long as possible."

  • Oysters_oil_5

    Fungus (like mushrooms) can be used in soils to feed on and clean up toxic chemicals / various neurotoxins.

    From a press release by the Helmholtz Center for Environmental Research:

    Because there is often a lot of traffic on the 'fungal highway’, the bacteria may come into close contact with one another, exchanging genetic material in the process. "It’s similar to the transmission of cold germs on a packed train," explains environmental microbiologist Dr. Lukas Y. Wick. "But unlike a cold, the new genes are usually an asset to the soil bacteria. They enable them to adapt better to different environmental conditions." Depending on the genes they receive through horizontal gene transfer, they may be able to adapt to new environmental conditions or access food sources which they were previously unable to exploit. For example, this might include the pollutants toluene or benzene contained in oil and gasoline, which to bacteria with the right genetic makeup are not only not harmful but actually very tasty food. So the passing on of this ability to other bacterial groups can be very advantageous in terms of the degradation of soil pollutants.

  • Seawaterbattery

    Nanotechnology scientists are working on a sodium-oxygen, seawater battery

    a promising alternative to Lithium

    Research into battery improvements has traditionally focused on Lithium as a necessary component. As a 2015 Nature report states:

    "... Rechargeable metal–oxygen batteries are very attractive owing to their reliance on molecular oxygen, which forms oxides on discharge that decompose reversibly on charge. Much focus has been directed at aprotic Li–O2 cells, but the aprotic Na–O2 system is of equal interest because of its better reversibility."

    Indeed, the other problem with Lithium is that as a rare earth element, it can be increasingly expensive. It also has a relatively small window when it comes to operational safety.

    Which brings us to nanotechnology-based options that use seawater as the catholyte — where "catholyte" is a fancy way of saying an cathode + electrolyte combined.

    From a recent release of the ACS Applied Materials & Interfaces publication:

    "In batteries, the electrolyte is the component that allows an electrical charge to flow between the cathode and anode. A constant flow of seawater into and out of the battery provides the sodium ions and water responsible for producing a charge. The reactions have been sluggish, however, so the researchers wanted to find a way to speed them up."

    And the scientists briefly summarize their method:

    "We applied porous cobalt manganese oxide (CMO) nanocubes as the cathode electrocatalyst in rechargeable seawater batteries, which are a hybrid-type Na–air battery with an open-structured cathode and a seawater catholyte. The porous CMO nanocubes were synthesized by the pyrolysis of a Prussian blue analogue, Mn3[Co(CN)6]2·nH2O, during air-annealing, which generated numerous pores between the final spinel-type CMO nanoparticles. The porous CMO electrocatalyst improved the redox reactions, such as the oxygen evolution/reduction reactions, at the cathode in the seawater batteries. "

    Hypersolar is a company working on creating a feasible hydrogen generator using nothing more than sunlight and any source of water...

    Imagine a generator that you can have in your back yard that runs NOT on dangerous gas cans of diesel, but on water... even dirty, gutter water! Even stale pond water! The prototype shown in the video uses water from the Salton Sea, which is known to be full of hazardous agricultural runoff.

    Here they have a working "prototype" with some expensive materials as part of the cells. They believe they can manufacture these less expensively.

    Watch the video and read why I think this company is the real thing.

    Things that make me believe this company is not out to scam anybody:

    -- Its founder is a dedicated scientist, with published academic research.

    -- Company now has a Highly-competent CTO

    -- It has an academic on board as a scientific advisor.

    -- It has an ongoing research agreement / relationship with the University of Iowa

    -- Continuous improvement in bringing down the cost of doing this on a large scale.

    This is a small team, and is currently a small-cap stock. However, we NEED these little ventures, because that is where breakthroughs happen. I have full confidence in the ability of the team to deliver value to its investors.

    Hypersolar IS a public company, and if you believe in the future of innovations like this, you can invest in HYSR at Tradeking. New investors, please sign up with this link: http://bit.ly/2dAQrUy

  • Smart-cities-infrastructure

    Portland to participate in Whitehouse's Smart Cities Initiative

    80 million investment to build smarter cities. There are some endeavors that are simply too much for any one city to take on by itself.

    NIST’s Global City Teams Challenge is establishing multi-team super-clusters to take on grand challenges too big for any single city team to tackle. Examples include multi-city resilience to large-scale natural disasters, intelligent transportation systems that work in any city, and regional air quality improvements through coordinated local action. This initiative brings together groups of communities formed around lead cities—Portland, Oregon; Atlanta, Georgia; Newport News, Virginia; Columbus, Ohio; Bellevue, Washington; Kansas City, Kansas; and Kansas City, Missouri—to work with NIST and its collaborators, including DOT, DHS Science and Technology Directorate, NSF, the Environmental Protection Agency, the National Telecommunications and Information Administration, the International Trade Administration, the Economic Development Administration, IBM, AT&T, CH2M, Verizon, Qualcomm Intelligent Solutions, Intel, US Ignite, and Urban-X, to develop ‘blueprints’ for shared solutions that will be collaboratively implemented in multiple cities and communities.

    NIST is announcing $350,000 in four new grants enabling 11 cities and communities to work together on innovative smart city solutions. The Replicable Smart City Technologies grants to teams of communities led by Newport News, Virginia; Bellevue, Washington; Montgomery County, Maryland; and Portland, Oregon focus on the development and deployment of inter-operable technologies to address important public concerns regarding air pollution, flood prediction, rapid emergency response, and improved citizen services through inter-operable smart city solutions that can be implemented by communities of all types and sizes.

    "According to a report, some Federal Pacific Electric panels failed to operate properly nearly 60% of the time in the event of a power surge. The homeowner had no way of knowing that too many electrical devices were plugged into one room. The devices required more electricity than the circuit could provide. “The wiring got hot enough to fry an egg,” the electrician reported. Normally, the circuit breakers should trip to cut off the electricity and prevent a fire. The Federal Pacific Electric breakers did not operate properly, resulting in two circuit breakers and a bus bar being burned."

    The Federal Aviation Administration is funding research to make this costly conductive concrete more affordable.

    This special concrete mix, studded with electricity-conducting ingredients, could help airports and other places run on time during inclement weather.

    "Potholes often originate from the liberal use of salt or de-icing chemicals that can corrode concrete and contaminate groundwater over time, Tuan said, making the conductive concrete an appealing alternative with lower operating and maintenance costs. The power required to thermally de-ice the Roca Spur Bridge during a three-day storm typically costs about $250 -- several times less than a truckload of chemicals, he said."

  • Sapling

    The fastest way to grow a forest; directions modified for an ecosteader audience / adapted from the source below:

    1. Test the soil's Ph to find out what what it lacks. Great soil has a healthy blend of Carbon, Nitrogen and Phosphorous -- all of which are generated from compostable materials.

    2. Identify what species should be growing in this soil, depending on climate. It does not need to be native.

    3. Acquire a locally-abundant biomass to feed the soil whatever nourishment it needs (may be an agricultural or industrial byproduct — like chicken manure or press mud, a byproduct of sugar production)  — but it can be almost anything. The less distance you have to haul the biomass the better.

    4. Amended the soil to a depth of ~one meter, plant saplings that are up to 80 centimeters high, packing them in very densely — three to five saplings per square meter.

    5. The forest itself be planted to cover at least 100 square-meters, minimum. This space grows into a forest so dense that after eight months, sunlight can’t reach the ground. "At this point, every drop of rain that falls is conserved, and every leaf that falls is converted into humus. The more the forest grows, the more it generates nutrients for itself, accelerating further growth. This density also means that individual trees begin competing for sunlight — another reason these forests grow so fast."

    6. Keep the forest watered and weeded for the first two or three years, after which it should become its own ecosystem and sustaining.

    7. Leave it alone -- allow that ecosystem to work. Not all will, but those that do do for a reason.

    What can we do as community citizens to promote ecologically sensible urban planning projects in our communities?

    Sites like CitizenInvestor think they might have the answer. . . as highlighted by a recent post in CityFix

    What role should crowdfunding play in our cities?

    "By allowing citizens to donate small amounts of money to projects of their choosing, urban planning can become a more participatory and inclusive process. These platforms also open up a new source of capital for projects that may not otherwise be funded.

    However, civic crowdfunding also presents risks. While it can make planning more participatory, it may exclude citizens who lack the ability to make significant donations. Further, it is unclear whether governments will turn to civic crowdfunding instead of funding projects that should be paid for with public funds. Finally, most civic crowdfunding projects remain small, and it is unclear whether the model will effectively scale up.

    Still crowdfunding is gaining momentum around the world. While is it most common in wealthier countries, it also has strong potential for opening up new capital in middle and lower income countries. It is already growing quickly in India, where a variety of crowdfunding platforms are emerging to fund arts and business ventures.

    Crowdfunding is growing as a tool being used to fund a variety of projects, including investments in start-up companies, real estate ventures, and alternative energies. Still, these innovative funding models are early in their growth. In time, civic crowdfunding may help reshape our cities to be more sustainable and responsive to citizens’ needs and desires."
