==Introduction==
===Objective===
[[File:Windbelt.JPG|thumb|left]]
The objective of the project is to design, build and implement multiple versions of the windbelt generator for [http://www.otrosmundoschiapas.org/ Otros Mundos]. Our initial goal was to power Otros Mundos' telecommunication devices in the field, using wind energy. However, the prototype developed did not generate sufficient energy to power these telecommunication systems. The refined goal for this work is to inspire interested people and to provide them the information necessary to create their own Windbelts.
 
=== Background on the client===
===Background on the energy source===
Energy from the wind is not a new technology, windmills have been around for centuries. Some authors believe to have discovered remains of stone windmills in Egypt, near Alexandria, that are believed to be 3000 years old. However, no evidence has been found that proves that the Egyptians had the necessary knowledge to harness the energy of the wind.<ref>http://books.google.com.mx/books?id=Z4bhObd65IAC&amp;amp;pg=PA563&amp;amp;dq=commercial+wind+turbine+systems+and+applications&amp;amp;hl=es&amp;amp;ei=org6TN_nHI-dnwe9tpjDAg&amp;amp;sa=X&amp;amp;oi=book_result&amp;amp;ct=result&amp;amp;resnum=1&amp;amp;ved=0CDIQ6AEwAA#v=onepage&amp;amp;q=commercial%20wind%20turbine%20systems%20and%20applications&amp;amp;f=truefckLR</ref> Wind energy is now being merely reintroduced to a society that has forgotten about it. The majority of the electricity used in the United States comes from fossil fuels <ref>http://www.umich.edu/~gs265/society/fossilfuels.htm</ref>; a non-renewable source of energy that supplies over 85% of our energy demands<ref>http://www.umich.edu/~gs265/society/fossilfuels.htm</ref>. However, Wind energy <ref>http://books.google.com.mx/books?id=5oCo0j6PmkQC&printsec=frontcover&dq=wind+energy&hl=es&ei=EWM9TL6iGIj0tgOA94TbCg&sa=X&oi=book_result&ct=book-thumbnail&resnum=9&ved=0CFgQ6wEwCA#v=onepage&q&f=false Book on wind energy] - "Wind, the moving breeze that carries pollen across forests, has energy. Wind energy moves kites through the air, turns wind turbines to produce electrical current.

Wind power can be used to generate electricity through the use of wind turbines and turbine free wind generators. ==== Climatology, San Cristobol de las Casas ==== San Cristobol de las Casas sits at a latitude of 16.75, longitude of -92.63, and an altitude 2,276m. The mean wind speed is 4.6 (km/h) for the last 9.5 years and it has been fairly steady with the highest speed recorded in May of 2004 with no months general windier than others. Highest monthly speeds were recorded in every month except July, September, and December. <ref>[http://www.tutiempo.net/en/Climate/SN_CRISTOBAL_LAS_C/05-2010/768450.htm Climate Data] - The team looked up the mean(average) wind speed for every month of every year since 2000 and took the average of all of those months in order to calculate the mean wind speed for the last 10 years...or really 9 years and 5 months since we're only half way through 2010. </ref>
=== Client Criteria ===
# Attach one large washer to a 4 inch screws.
# Attach the 10 inch piece of ribbon with a small piece of electrical tape and wrap it all of the way around the screw in the space between the washers. This piece of ribbon should be a big enough that its diameter is bigger than the size of the magnets you're going to use to produce electricity<ref>see [[HSU Chiapas Windbelt ASE/Literature review]] for more on electricity.</ref>
# Slip the other 2.5 inch washer onto the screw leaving about 1.5 inches of space between the two washers. (You can adjust the size of the space between them based on how big you want to roll your coil.)
# Carefully take the end of the copper coil and wrap it around the end of the screw that is on the outside of the 2.5 inch washer. Make sure it's firmly wrapped so that its stays in place.

**Wind, the moving breeze that carries pollen across forests, has energy. Wind energy moves kites through the air, turns wind turbines to produce electrical current. The sun warms the ground and the air above it, causing the air to move.
*[http://cedb.asce.org/cgi/WWWdisplay.cgi?257021 ASCE Journal]
**The ASCE article comments on the rapid growth of wind energy as world demands increase for clean energy. Larger, more efficient wind turbines have been built that are able to function in offshore farms. The new media for wind turbines, the ocean, will pose challenges for designer in building safe off-shore wind turbines.
 
*[http://humboldt-dspace.calstate.edu/xmlui/bitstream/handle/2148/542/sheppard_thesis_final_digital_scholar.pdf?sequence=1]
 
This is a thesis done by a graduate student (Colin John Ritter Shepperd) at Humboldt State University entitled "Analysis of the measure-correlate-predict methodology for wind resource assessment." This was helpful information because he explains in great detail the ideas behind wind power, as well as the various equations that help us figure out how much actual power we can get from wind. An excellent example of his work: "An important characteristic of wind power conversion is the non-linear re- lationship between the speed of the wind and the available power. Wind power density (WPD) is the amount of power available in a unit area of the air perpen- dicular to the flow of the wind. WPD has units of (W/m2 ) and is calculated by the following expression (Gipe 2004): W P D = 1 /2 ρV 3, where V is the wind velocity (m/s) and ρ is the air density (kg/m3 )." (page 5)
 
==== Climatology, San Cristobol de las Casas ====

**This is a website that has data recording the various weather information, and for us more importantly it shows wind speeds (km/h) for San Cristobol de las Casas, which sits at a latitude of 16.75, longitude of -92.63, and an altitude 2,276m. There was plenty of data going all the way back from the 1970's. I looked up the mean(average) wind speed for every month of every year since 2000 and I took the average of all of those months in order to calculate the mean wind speed for the last 10 years...or really 9 years and 5 months since we're only half way through 2010. The mean wind speed is 4.6 (km/h) and it has been fairly steady with the highest speed recorded in May of 2004 and in general I cannot say that any certain months are windier than others. Highest monthly speeds were recorded in every month except July, September, and December. This information will help us calculate how much energy we will be able to produce from our wind belt powered mechanism(s). If we can create a system of wind belts that produce enough energy to power a cellular phone or an LED light with 4.6(km/h) of wind speed then we will succeed in our goal to create power from a renewable source of energy, wind!

==== Existing Models ====
*[[http://www.humdingerwind.com/#/wi_micro/| microbelt specs]Microbelt specifications] **the The microbelt, seen below in figure Figure 2, can provide clean energy to power the billions of wireless light and power sensors around the world; by using aeroelastic flutter rather than a spinning turbine. The microbelt is able to provide power to wireless sensors as long as there is airflow hitting it. For example, under a car, inside the ducting of buildings, or at the outside of a building.Table 1 and Figure 3 show the correlation b/w between wind speed and power output of the device. The higher the wind speeds, the greater the electrical current.

*[http://www.humdingerwind.com/#/wi_medium/ Windcell]
**The windcell, seen in Figure 3(Clich the link above), is a one meter long windbelt electricity generator. This design was developed to meet energy needs that range from 0.1kwh-1kwh per month. Be sure to watch the video!
*[http://www.humdingerwind.com/#/wi_large/ Windcell Panels]
**This windbelt design can be set up into arrays of windcells that can be hooked up to supplement the grid. This sort of windbelt design could be on every roof and wall of everything from skyscrapers to personal homes.

*D-Lab Windbelt
**Team SEAASE's first attempt at creating a working Windbelt was fashioned after the "D-Lab Windbelt". The "D-Lab Windbelt" is modeled after Shawn Frayne's "Humdinger Windbelt". After carefully studying the D-Lab video on youtube.com and the online instructions for the device, Team SEA began collecting materials from various locations in San Cristobal. A large amount of the tools used in the creation of the SEAASE/D-Lab Windbelt Prototype #1 were borrowed from Otros Mundos, the organization that has commissioned Team SEA and HSU ASE to build a Windbelt. After collecting the necessary materials for the D-Lab Windbelt , Team SEA ASE began construction 7-10-10.

==== Materials for "RCEA Windbelt" ====**One possible windbelt generator design could look like a tower of windbelts connected in series to produce the necessary energy to power larger electronic devices such as laptops or stereos. This design would work in the same way as the Humdinger with the only difference being the windbelts would be stacked on top of each other in a tower, with multiple windbelts using the same coils to generate electricity. This disign is similar to Humdingers Windcell Panel, but made in our own Mexico style.

*PLANE:
**Based off of the same idea as the Plane windbelt, a Kite windbelt could be constructed. Using the energy of the wind to lift the Kite one could angle the kite and dive to the left and the right in succession making the kite drop and rize rapidly. This rapid ascent and decent would generate high wind speeds and would create a lot of flutter and hopefully a lot of energy
