Wind power resources on the eastern U.S. continental shelf are est.docxalanfhall8953
Wind power resources on the eastern U.S. continental shelf are estimated to be over 400 GW, several times the electricity used by U.S. eastern coastal states. The first U.S. developer proposes to build 130 large (40 story tall) wind turbines in Nan- tucket Sound, just outside Massachusetts state waters. These would provide 420 MW at market prices, enough electricity for most of Cape Cod. The project is opposed by a vigorous and well-financed coalition. Polling shows local public opinion on the project almost equally divided. This article draws on semistructured interviews with residents of Cape Cod to analyze values, beliefs, and logic of supporters and oppo- nents. For example, one value found to lead to opposition is that the ocean is a special place that should be kept natural and free of human intrusion. One line of argument found to lead to support is: The war in Iraq is problematic, this war is “really” over petroleum, Cape Cod generates electricity from oil, therefore, the wind project would improve U.S. security. Based on analysis of the values and reasoning behind our interview data, we identify four issues that are relevant but not currently part of the debate.
Introduction
Recent assessments of renewable energy show that wind power has, since the turn of the century, become cost-competitive in the sites with the most favorable wind regimes (Herzog et al., 2001). Until very recently, large-scale North American wind resources were believed to exist in the Great Plains of the United States, northern Canada, and central Canada only (Grubb & Meyer, 1993). Although these huge resources are enough to meet the entire continent’s electrical needs, they are distant from the large coastal cities where electricity is primarily consumed—imposing a need for costly large-scale transmission lines (Cavallo, 1995). In just the last couple of years, it has been recog- nized that the Atlantic Ocean also has a large wind resource on the continental shelf, close to East Coast cities. Three or four manufacturers have developed large wind elec- tric turbines designed to be placed offshore, in waters up to 20–30 m in depth. To date these have been placed only in European waters. By late 2003, the resources, the tech- nology, and the economic viability had all come together in the Eastern United States, potentially allowing large-scale deployment to begin by 2005.
The furthest advanced of a handful of proposed U.S. offshore wind developments is in Nantucket Sound, off the Southern coast of Cape Cod, Massachusetts. This proposal has engendered a widespread, well-organized, well-financed, and politically potent op- position. This movement’s strength, and the apparent contradiction of such opposition coming from a population thought of as politically liberal and environmentally con- cerned, have garnered national press coverage (e.g., Burkett, 2003). A second project was proposed by the Long Island Power Authority for the southern edge of Long Island, with an .

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

18. The Benefits of Wind Energy for Utilities
Wind power provides a clean source of electricity and helps keep electric
rates low.
Wind energy costs have dropped over the past few years as wind turbine
technology has developed.
Wind energy is now one of the most cost-effective sources of new electricity
generation.
Utilities can lock in wind energy prices for 20 to 30 years because the fuel is
free. That's one reason wind power has added 35% of all new generating
capacity to the U.S. grid since 2007.
Electric utilities have a unique role in bringing wind power to their retail
customers, who are expecting their electricity providers to use more clean
energy.
19. Michigan utilities are working towards a
mandate of generating 10% of the state's
energy from renewable sources by 2015.
As that deadline approaches, wind power
is proving to be a key component.
20. Kim Horrocks thinks wind turbines like this one
at his store (Horrocks in Delta Township) will be
a factor in making the country less dependent
on foreign oil. It cost $15,000 five years ago and
supplies less than 10% of their energy needs.
24. Current State of Wind Power in Michigan
According to the Great Lakes Wind Collaborative:
• Michigan has high potential for both onshore and offshore wind
power development.
• Installed onshore wind capacity has increased from 400 MW in 1999
to 8,876 MW at the start of 2010.
• As of mid-2010, an additional 5,809 MW of onshore wind projects
were underway.
• Off-shore wind projects have been proposed in all of the Great
Lakes, as well as in Lake St. Clair.
• The wind sector is an ideal growth market for manufacturing firms in
the Great Lakes.
According to Eric Shreffler, Director of New Markets for MEDC in 2008:
“Michigan ranks fourth nationwide among states with the most
wind turbine production capacity.”

28. Offshore Wind
Offshore wind resources in the United States are not
only vast; they are located near fast-growing urban
areas.
Offshore wind development offers a source of clean,
domestic, renewable energy to meet electricity demands.
Wind farms are also likely to be built in areas that can
facilitate smooth and cost-effective integration of wind
into the overall electric system.
While many other countries have wind projects installed
in offshore waters, the U.S. does not yet have any
offshore wind projects.
31. Challenges for Offshore
Wind
Offshore wind power in the United States is still in its infancy, compared to
land-based wind.
Offshore wind projects must strike a viable balance between technological
and economic challenges.
The offshore technology has had to adapt to more challenging
environmental elements in order to be successful.
The latest generation of offshore turbines is equipped to meet the
challenges of tough weather conditions, which can limit access for routine
maintenance.
Benefit: Offshore turbines can continue to take advantage of
economies of scale as their size increases.

36. What is biomimicry?
“The practice of developing sustainable
human technologies inspired by nature.”
38. Janine Benyus, an expert on biomimicry, says --
We can mimic form (the shape of a plant
or animal).
We can mimic process.
We can mimic an ecosystem (like having a
city that functions as well as a forest).
39. Quote
“Those who are inspired by a model other than
Nature, a mistress above all masters, are
laboring in vain.”
Leonardo Da Vinci
The earliest known windmill design dates back 3000 years to ancient Persia where they were used to grind grain and pump water. Reeds were bundled together to create vertical paddles that spun around a central axis. Carefully placed exterior walls ensured that wind would primarily drive the potentially bidirectional system in the desired direction. Of course, the use of wind power in sailing predates the inventions of windmills but these are the first known use of wind to automate mechanical/manual everyday tasks.

Published by NREL, here is a wind resource map for the United States. Also, it shows the yearly electricity production estimated for a small wind turbine.
Michigan’s annual average wind speed estimates at 80 meters above the ground. (Published by the National Renewable Energy Laboratory.)
Flagging is a way to determine wind speeds in an area by studying the effect of strong winds on area vegetation. Trees, especially conifers or evergreens, can be permanently deformed by strong winds. By using the Griggs-Putnam Index, wind speeds can be estimated.
Direct monitoring by a wind resource measurement system at a site provides the clearest picture of the available resource. Wind measurement systems are available for costs as low as $600–$1,200. The measurement equipment must be set high enough to avoid turbulence created by trees, buildings, and other obstructions. The most useful readings are those taken at hub-height, the elevation at the top of the tower where the wind turbine is going to be installed.
There are many resources you can use on the internet to obtain information when you are considering using wind turbines as a renewable energy source.
This DOE publication on Small Wind Electric Systems shows a variety of wind turbines in use on its cover and is a good source of information.
Wind turbines use the motion of the wind to turn a shaft attached to a generator, which makes electricity. The size of the turbine and the speed of the wind determine how much electricity it will make. The larger the rotor, the more energy it can capture. A small wind energy system will produce a power output of 100 kilowatts (kW) or less. Most systems are smaller than that, and have power ratings ranging from 2 to 10 kW. This can provide some, if not all, of a homeowner’s electricity needs.
A grid-connected wind turbine can reduce your consumption of utility-supplied electricity for lighting, appliances, and electric heat. If the turbine cannot deliver the amount of energy you need, the utility makes up the difference. When the wind system produces more electricity than the household requires, the excess is sent or sold to the utility.
According to many renewable energy experts, a small "hybrid" electric system that combines wind and solar (photovoltaic) technologies offers several advantages over either single system. For example, they can draw energy from one source when the other is weak and vise versa. In much of the United States, wind speeds are low in the summer when the sun shines brightest and longest. The wind is strong in the winter when less sunlight is available. Because the peak operating times for wind and solar systems occur at different times of the day and year, hybrid systems are more likely to produce power when you need it. Many hybrid systems are stand-alone systems, which operate "off-grid"—not connected to an electricity distribution system.
FIVE WIND TURBINES WITH SOLAR PANELS STAND BEHIND GENOA TOWNSHIP HALL, THANKS TO A $94,919 EECBG GRANT. The Windspire wind energy conversion turbines are manufactured in Manistee, Michigan and cost $11,400 each, making the total cost $57.000 for five turbines. At a recent DOE monitoring visit, Mike Archinal (Township Manager), reported they collected more energy from the solar panels due to the turbines stopping during high winds and having to be reset.
The American Wind Energy Association has published these Performance and Safety Standards for small wind turbines.

This map section shows wind power potential and the proximity of high voltage transmission lines in the 4-county study area in West Michigan. Higher wind power classes represent higher potential for wind energy generation.
This research buoy will aid the offshore wind assessment study conducted by Grand Valley State University, the University of Michigan and MSU. The buoy is one of three in the world and is an eight-ton, 20-by-10 foot boat-shaped structure that can measure wind characteristics up to 150 meters above the water using advanced wind sensor technology. Real-time data will be transmitted to researchers on land. The research will provide information to support possible future development of offshore wind energy technology in the Great Lakes.
Here are the answers to our trivia questions at the beginning of the presentation.
Read slide.
I give you an example of the use of biomimicry – the Whalepower Wind Turbine. What do Humpback Whales have to do with wind power? Humpback whales have small bumps known as tubercles along the leading edge of their fins. This means improved efficiency in swimming for whales. By adding those tubercles to the edge of a turbine blade, it adds more power without increasing drag which can cause the blade to shake. Also, this design could reduce a noise problem called “tip chatter.”
