Why Is An Oak Leaf Not Square?

Hi Jon

You will get more production out a curved
line than a straight line.

Permaculture is fascinating in that it
teaches us to look at nature's non-linear
systems, and understand the patterns of
natural phenomena.

This video looks at the idea that nature's
patterns allow for maximum accessibility
and minimum amount of path.

Planting in circles instead of rows is a
practical use of this concept.

New WRI paper: Financing the Energy Transition: Are WB, IFC, and ADB Energy Supply Investments Supporting a Low-Carbon Future?


http://connect.wri.org/l/120942/2015-11-10/2pvl7z/120942/107917/spacer.gif
A new paper by the World Resources Institute (WRI), Financing the Energy Transition: Are World Bank, IFC, and ADB Energy Supply Investments Supporting a Low-Carbon Future?, provides a first-cut assessment of how the energy supply investments of the World Bank, International Finance Corporation (IFC), and Asian Development Bank (ADB) align with the Paris Agreement goal to limit global temperature rise to well below 2°C.

Finance provided and catalyzed by multilateral development banks (MDBs) will help pay for implementation of the UN Sustainable Development Goals and the Paris Climate Agreement in many developing countries. Although MDBs already track and report on their climate finance, less is known about the extent to which the MDBs are financing projects that are consistent with a low-carbon future.

Our working paper looks beyond climate finance to provide an initial assessment of whether a sub-sample of MDBs are financing energy supply infrastructure that is consistent with pathways that limit warming to below 2oC. We analyzed recently approved (2015-2016) and planned energy supply projects of the World Bank, IFC, and ADB—over 400 total—including nearly 300 infrastructure projects with an estimated $35 billion of finance for energy supply infrastructure in developing countries. Our analysis raises important policy questions for MDBs, their shareholders, and civil society.

Our blog post, 
Are Multilateral Development Banks Supporting a Low-Carbon Future?, offers more insights into the paper’s findings.

We officially launched the paper at the recent G7 Environment Ministerial in Bologna, and captured the highlights from the meeting in a blog post, U.S. Paris Pull-Out Sparks Discord and Dialogue for G7 Environment Ministers.

You can find the 
full paper here. We hope that you will find it useful in your work and look forward to hearing your feedback.

THREE OF FOUR PEOPLE WILL FACE THREAT OF HEAT RELATED DEATH BY 2100

  Posted on June 28, 2017 by 


A new study from Nature.com indicates that 30 percent of the world’s population is exposed to potentially deadly heat for 20 days per year or more. According to the study, up to three in four people will face the threat of heat related death by 2100.
From the report summary:
Climate change can increase the risk of conditions that exceed human thermoregulatory capacity. Although numerous studies report increased mortality associated with extreme heat events, quantifying the global risk of heat-related mortality remains challenging due to a lack of comparable data on heat-related deaths.
Here we conducted a global analysis of documented lethal heat events to identify the climatic conditions associated with human death and then quantified the current and projected occurrence of such deadly climatic conditions worldwide. We reviewed papers published between 1980 and 2014, and found 783 cases of excess human mortality associated with heat from 164 cities in 36 countries.
Based on the climatic conditions of those lethal heat events, we identified a global threshold beyond which daily mean surface air temperature and relative humidity become deadly. Around 30% of the world’s population is currently exposed to climatic conditions exceeding this deadly threshold for at least 20 days a year.
By 2100, this percentage is projected to increase to 48% under a scenario with drastic reductions of greenhouse gas emissions and 74% under a scenario of growing emissions. An increasing threat to human life from excess heat now seems almost inevitable, but will be greatly aggravated if greenhouse gases are not considerably reduced.

According to Richard Keller, a University of Wisconsin-Madison professor of medical history, heat kills ten times more people in the U.S. than tornadoes or other extreme weather events. See more of our climate change coverage here.

You'll only need to charge your phone four times a year after new discovery


Scientists have created a new material for processors which uses 100 times less energy than the semiconductor-based systems currently used
Brush your teeth, comb your hair, charge your phone; plugging in your device has become a twice-daily habit. 
But you may be able to charge your phone just once every three months in the future.
Scientists have engineered a new material which allows processors to function using 100 times less energy.


Researchers at the Universities of Michigan and Cornell have created a new magnetoelectric multiferroic material

It is formed of thin layers of atoms which make up a magnetically polar film. This can be flipped from positive to negative with only a tiny pulse of energy.
This principle could be used to transmit binary code, the streams of 1s and 0s, on which our computers operate. This means they could send and receive data using just a fraction of the electricity.

Currently, processors are built using semiconductor-based systems which need a constant flow of electricity. But processors built using magnetoelectric multiferroic systems would only need short pulses of electricity, using far less energy.  
Electronics currently consume five per cent of total global energy, and are the fastest-growing energy consumer, according to Ramamoorthy Ramesh, associate laboratory director for energy technologies at Lawrence Berkeley National Laboratory.
By 2030, electronics could consume 40 to 50 per cent of global energy. Devising energy-efficient processors could have a significant impact on our global energy footprint. 
Not to mention our mood, when our phone cuts out without a plug in sight.

Mumbai Activist Raped For Exposing Mangrove Destruction

rape-victim
Mumbai | 29 June: Ghar Bachao Ghar Banao Andolan (GBGBA) strongly condemns the rape of a woman environment activist by five men who were apparently aggrieved by the woman’s complaint about destruction of mangroves.
GBGBA is also shocked to know the callousness of the Mumbai Police department who didn’t take immediate steps which would have avoided such a heinous crime.
Generally, every informal settlement in Mumbai has a strong and active nexus of slumlords and local police which is involved in illegal selling of govt. and private plots to poor working class of the city to construct their dwellings. This nexus controls water and electricity supply. Sell plots by cutting trees of mangroves and fill the marshy land by filling debris. Members of this nexus also harass the women living in the community and in nearby areas physically and sexually. This nexus takes full advantage of the helplessness of poor working class of the city who due to the unavailability of cheaper housing option fall prey to slumlords. Slumlords control areas far away from the sight of the city-mainly marshy areas and only allows construction of a hut when they are paid some money. Police is directly involved in this.
Several activists GBGBA have in past made complaints to local police station of their respective areas complaining cutting mangroves, public consumption of hooch, harassment of women and so on only to be returned with hollow assurance.
There will be considerable fall in the number of crimes in Mumbai if such nexuses are systematically brought down.

World’s Largest Wind Turbine Would Be Taller Than the Empire State Building

Massive, flexible blades would bend with storm winds like the palm trees that inspired them
By Annie Sneed on June 26, 2017




Wind energy is soaring in the U.S.; the nation’s renewable energy capacity has more than tripled in the past nine years, and wind and solar power are largely responsible. Now businesses want to harness even more wind energy, at a cheaper price—and one of the best ways to lower cost is to build bigger turbines. That’s why an alliance of six institutions led by researchers at the University of Virginia are designing the world’s largest wind turbine at 500 meters tall—almost a third of a mile high, and about 57 meters taller than the Empire State Building.

Turbines are already noticeably larger than they were 15 or 20 years ago. Size varies, but today’s typical wind farm towers stand around 70 meters tall, with blades about 50 meters long. Their power output depends on size and height, but it generally ranges between one and five megawatts—on the upper end, that’s enough to power about 1,100 homes. “There's this motivation to go to larger wind turbines, and the reason is pretty much economics,” explains John Hall, an assistant professor of mechanical and aerospace engineering at the University at Buffalo, S.U.N.Y. One reason giant turbines are more cost-effective is that wind blows stronger and more steadily at greater altitudes. Thus, “you capture more energy” with a taller structure, says Eric Loth, project leader of the massive turbine project, which is funded by the U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA–E).

Another reason wind experts say bigger is better: longer turbine blades also catch the wind more efficiently, and taller towers enable lengthier blades. A turbine’s power is directly related to its “swept area”—the circular area covered by the blades’ rotation—explains Christopher Niezrecki, a professor of mechanical engineering and director of the Center for Wind Energy at the University of Massachusetts Lowell. And this relationship is not linear—if blade length doubles, a system can produce four times as much energy, Niezrecki explains. He notes that bigger turbines also have a lower “cut-in” speed, the wind speed at which they can start generating energy.

Loth’s team wants to design a 50-megawatt system with blades 200 meters long, much larger than today’s wind turbines. If the researchers succeed, they believe the turbine would be 10 times more powerful than existing equipment. But the scientists do not intend to simply supersize conventional designs; they are fundamentally changing the turbine structure. The ultralarge machine will have two blades instead of the usual three, lowering the weight of the structure and cutting costs. Loth says that reducing the number of blades would ordinarily make a turbine less efficient, but his team is using an advanced aerodynamic design that he says largely makes up for those losses.Concept of SUMR project.

The team also envisions these gigantic structures standing at least 80 kilometers offshore, where winds tend to be stronger and where people on land cannot see or hear them, according to Loth. But powerful storms hit such places—off the U.S. east coast in the Atlantic Ocean, for example—so Loth’s team faced the quandary of creating something massive that is also relatively lightweight and still resilient in the face of hurricanes. To tackle the problem, the researchers looked to one of nature’s own design solutions: palm trees. “Palm trees are really tall but very lightweight structurally, and if the wind blows hard, the trunk can bend,” Loth says. “We’re trying to use the same concept—to design our wind turbines to have some flexibility, to bend and adapt to the flow.”

In the team’s design the two blades are located downwind of the turbine’s tower, rather than upwind as they are on traditional turbines. The blades also change shape with the wind’s direction, similar to a palm tree. “When the blades bend back at a downwind angle, you don’t need to build them as heavy or strong, so you can use less material,” Loth explains. This design also lessens the possibility that strong winds will bend a spinning blade toward its tower, potentially knocking the whole structure down [Video]. “The blades will adapt to high speeds and start to fold in, so there are less dynamic forces on them,” Loth says. “We’d like our turbines to be able to handle higher than 253-kilometer-per-hour winds” in nonoperating conditions. Above a wind speed of 80 to 95 kilometers per hour the system would shut down and the blades would bend away from the wind, so they could withstand violent gusts, Loth adds.

The 500-meter turbine still faces challenges—there are good reasons no one has yet built one close to this size: “How do you make 200-meter blades? How do you put them together? How do you erect such a tall tower? Cranes only go so high. And with offshore wind, [there are] additional complications,” Niezrecki says. The team’s design includes a segmented blade that could be assembled from pieces on site, but Niezrecki notes the wind industry has not quite figured out how to segment the blades just yet. “There are lots of research questions to be addressed,” he says. “It’s definitely high risk, but there’s also potential for high reward as well. I don’t think those problems are insurmountable.” Hall also questions whether such a massive turbine is the optimal size. “We are figuring out that bigger is better. The question is, how much bigger? We need to find that sweet spot,” he says. “We’re going to learn a lot from this project.”

Loth and his team have yet to test a prototype; they are currently designing the turbine’s structure and control system, and this summer they are building a model much smaller than the real thing—about two meters in diameter. Next summer they plan to construct a larger version with two 20-meter-long blades, which will produce less than a megawatt of power and will be tested in Colorado. Loth himself is not 100 percent certain his team’s mammoth turbine will become a reality but he is sure it is worth trying. “This is a very new concept, so [there are] definitely no guarantees it will work,” he says. “But if it does, it will revolutionize offshore wind energy.”

New IRENA Report: Accelerating the Energy Transition through Innovation

Dear Colleagues,

I would like to draw your attention to a new paper from the International Renewable Energy Agency that sheds light on the conditions needed to nurture low-carbon technology innovation for renewable energy to flourish. Technological breakthroughs and new business models are still necessary if we are to keep the rise of global temperatures below 2 degrees Celsius. Accelerating the Energy Transition through Innovation identifies the elements of a flexible policy framework for innovation that will enable the decarbonisation of the energy sector by 2050, it also builds on and expands the analysis prepared at the request of the German G20 Presidency – released earlier this year.

Based on the current status and future needs for low-carbon technologies, thirteen distinct sectors of the energy system were assessed, spanning both power generation and the end-use sectors of energy demand. The assessment finds renewables could account for two-thirds of primary energy supply in 2050, up from just 16 per cent today. This means the growth rate of the share of renewables in total final energy consumption needs to rise seven-fold and be sustained until 2050.

Prevent Mosquito Breeding Sites Around Your Home

An ounce of prevention is worth a pound of cure. Tip. Toss. Turn. Tilt.

Mosquitoes are not only a nuisance; they can also carry and spread serious disease to humans and pets.
Walk around your house, patio, garage, etc. and look carefully for anything that retains water – even just a little bit of water. If you find any, dump the water and either throw the item away or store it in or under something that does not collect water.
Standing water is public enemy number one when it comes to infestations, because mosquitoes usually lay their eggs in unmoving water.
Moquitos can breed in something as small as a soda bottle cap with a 1/4″ of water!
According to the Maryland Department of Agriculture, the Zika virus​ is spread primarily through the bite of certain species of infected Aedes mosquitoes. The best way to avoid the Zika virus is to prevent mosquito bites. And the best way to avoid bites is to eliminate areas where these mosquitoes lay their eggs. These areas are called “breeding sites.”
Some species of Aedes mosquitoes breed in containers of standing water around the home rather than in wetland areas. Your home can be a major breeding ground!
For best results, get your closest neighbors involved and share these tips with them.
Organize a “Community Clean Up Day” with your neighbors or homeowners association to educate your neighborhood about what they can do to help reduce mosquito populations.
Below are some ways to prevent mosquito breeding without the use of chemical pesticides.

29 Ways to Prevent Mosquito Breeding Sites in Standing Water Around Your Home
Potential Breeding SiteHow to Correct
Any container capable of holding at least a teaspoon of water 1/4" deepThrow away, turn over, empty once a week or drill holes in the bottom.
Bird bathsDump out once a week or flush out with garden hose.
Pet water bowlsRinse out once a week.
Potted plants with saucersEmpty saucers or flush out with garden hose once a week.
Buckets, watering cans, drinking glasses, styrofoam cups, bottle caps, other trash that can hold waterStore inside or turn over. If trash, throwaway.
Tarps or other plastic covers, flexible sandbox coversDrain water trapped in folds and arrange so that water runs off.
Gutters, including “covered” typesClean so water runs freely.
Garbage cans, other barrels Upturned garbage can lidsKeep cans covered or drill holes in bottom. Keep lid on can or turned so
water runs off. If collecting rain water, cover with screen.
Old tiresDispose of at your local recycling facility. If used for playground
equipment, drill holes for water to run. If on ground, be sure holes
are not blocked by mulch.
Old playground equipmentRemove and dispose of. If it must be stored, put under cover.
Be sure water drains off.
Children’s toys, especially plastic toys, “Kiddie Coops,” etc.Store inside or turn so that places that can hold water are turned down. Some toys have compartments that hold water on both sides.
Wading pools, unused or abandoned swimming poolsTurn over kiddie pools when not in use. Larvicide unused swimming
pools with mosquito dunks once a month. (Mosquitoes can’t breed in
maintained swimming pools because of the chemicals used.)
Wheelbarrow stored outsideTurn over when not in use.
Flat roofsInspect for water pools.
Dripping outdoor faucets and window air conditionersIf puddling, repair faucet. Place rocks under window air conditioner
to ensure water runs off or fill hole with dirt.
Ornamental ponds without fishStock with fish, apply larvicide or filter/aerate water.
(Fish eat mosquito larvae.)
Boats, canoesPump out bilges. Turn over canoes and small boats.
If not possible to turn over, dump out after each rain.
Under decks, porches or outbuildings: stored items, depressions in dirt or plastic ground liningsFill in depressions. Remove or turn over any stored items that hold water.
Pipes, plumbing supplies with elbows(comer joints)Store under cover. If they must be outside, arrange so openings point
down, not up.
Drainage ditch, culvert or other low areas clogged by grass and weed clippingsRemove grass and weed clippings so water can flow and/or drain freely.
Flexible plastic pipe to take water away from downspoutReplace with smooth pipe. The grooves can hold enough water to breed mosquitoes. Or fasten screen or old nylon stocking to
end with duct tape.
Base of patio umbrella or portable basketball standFill with sand or, if filled with water, be sure to screw on plug.
Keep water out of depressions on stand also.
Outdoor grillsKeep covered. Be sure vent is closed also.
Bromeliads (plants that hold water), holes in trees or cavities formed by multiple tree trunksTurn plant over to dump water. For trees or plants too large to turn over, flush out cavities with garden hose once a week.
Holes in trees or cavitiesTurn over, flush out cavities with garden hose once a week.
Outside drainsCover with screening or larvicide with “mosquito dunks/pellets.”
Sump pumpsCover with screening
BambooCut down and regularly mow remaining “stumps” so they
can’t hold water
Hollow fence posts without capsPut caps on open chain link or plastic fence posts.
Plastic in gardens to prevent weedsUse landscape cloth that will allow water to pass through
instead of plastic sheets that hold water.
