    • Eco Project ResearchCountry / Geographic Region Republic of South AfricaThe Republic of South Africa is a country located at the southern tip of Africa, with a 2,798kilometers (1,739 mi) coastline on the Atlantic and Indian Oceans.South Africa is known for a diversity in cultures and languagesEnglish has a large role in public and commercial life, it is nevertheless only the fifth most-spoken home language.About a quarter of the population is unemployed and lives on less than US $1.25 a day.The extreme southwest has a climate remarkably similar to that of the Mediterranean with wetwinters and hot, dry summersThis region is also particularly known for its wind, which blows intermittently almost all year [hide]Climate data for Cape Town, South Africa Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Year Average high 26.1 26.5 25.4 23.0 20.3 18.1 17.5 17.8 19.2 21.3 23.5 24.9 22.0 °C (°F) (79) (79.7) (77.7) (73.4) (68.5) (64.6) (63.5) (64) (66.6) (70.3) (74.3) (76.8) (71.6)Average low °C 15.7 15.6 14.2 11.9 9.4 7.8 7.0 7.5 8.7 10.6 13.2 14.9 11.4 (°F) (60.3) (60.1) (57.6) (53.4) (48.9) (46) (44.6) (45.5) (47.7) (51.1) (55.8) (58.8) (52.5) Precipitation 15 17 20 41 69 93 82 77 40 30 14 17 515 mm (inches) (0.59) (0.67) (0.79) (1.61) (2.72) (3.66) (3.23) (3.03) (1.57) (1.18) (0.55) (0.67) (20.28)Avg. precipitation 5.5 4.6 4.8 8.3 11.4 13.3 11.8 13.7 10.4 8.7 4.9 6.2 103.6 days Sunshine hours 337.9 299.9 291.4 234.0 204.6 174.0 192.2 210.8 225.0 279.0 309.0 334.8 3,092.2 Source: Hong Kong Observatory[51]Climate: mostly semiarid; subtropical along east coast; sunny days, cool nightsNatural resources: gold, chromium, antimony, coal, iron ore, manganese, nickel, phosphates,tin, uranium, gem diamonds, platinum, copper, vanadium, salt, natural gasLand use: arable land: 10%permanent crops: 1%

It helps usto know what kind of environment we will be sending our floating houses to. It will help usmake good enhancements and changes to prototypes we create so they can work to their bestpotential. Knowing the amount of annual rainfall will especially help us with our designs. This is the South American Flag; although it isn’t essential to our research, it will be good to know.
    • This is a picture of the country South Africa, The exact location of where we will be shipping our houses is important for obvious reasons. A more detailed map of South Africa will help usdetermine where in South Africa needs the houses the most. Areas near rivers or coastlines aremost likely to floodNeedhttp://www.actsa.org/Pictures/UpImages/pdfs/ACTSA_South_Africa_country_profile.pdfPretoria – With the incessant rains introducing a whole new dynamic to the lives of millions ofSouth Africans, the nation has joined hands to deliver much needed relief to those who havebeen most adversely affected by the floods.
    • The Department of Social Development, business sector, civil society and faith basedorganizations have formed a task team, which will primarily coordinate humanitarian assistanceto people across the country.“The function of this team is to … respond to the immediate emergency priority needs, while atthe same time, laying the foundations for early and eventual long-term recovery of the affectedcommunities,” said Social Development Minister, Bathabile Dlamini, during a media briefing onSunday.South African authorities say at least 39 people have died in flooding and thunderstorms in theeastern part of the country.Provincial disaster management confirmed Friday that 26 people, including 4 children, havedied as a result of adverse weather conditions in the rural Eastern Cape province since mid-DecemberVISITOR FACT SHEET: THE DECLARED STATE OF DISASTER DUE TO FLOODS IN SOUTH AFRICA1. The general public, investor community and tourists are encouraged to continue with theirplanned projects in, and travel to, the areas where a state of disaster has been declared BUT toalso consider warnings given and other precautionary measures issued in respect of specificareas falling within and outside the borders of the declared areas.2. The numbers that foreign tourists / business people can call to get the latest informationon the state of floods in the country or the areas they intend travelling to are the following:· Weatherline: (+27) 082162.· EMS: (+27) 10177 (Emergency services)
    • Information from the visitor fact sheet will help us know what exactly we’re working against.Knowing locations of disaster areas will also help us know where people need our houses themost.In South Africa, weather-related incidents, including floods, lightning strikes and tornadoes, arethought to have killed 40 people between mid-December 2010 and 17 January 2011, and morethan 6,000 people had been displaced, according to the National Disaster Management Centre.Recyclable MaterialsAcceptable items are the same for the curbside program, drop-off locations and staffedrecycling centers except as noted below (see Exceptions):FIBER MATERIALSPAPER • White or mixed office paper, computer paper, file folders and manila and regular envelopes, mail items, junk mail, brown paper grocery bags, telephone books, and magazines/catalogs • Food-free pizza boxes, paperboard, cereal and gift boxes • Newspapers with slick advertising inserts • Flattened cardboard pieces no larger than approximately 2 ft x 2 ft • NO bound catalogs over 1 inch thick or glued bindings - NO plastic or foil backed paper • NO soiled or wax-coated cardboard like frozen food boxes and milk/juice cartons • NO wrapping paperCO-MINGLED MATERIALSGLASS • Food and drink bottles and jars (clear, brown, green, blue) - remove lids and rinse.

THANK YOU FOR DOING YOUR PART TO MAKE LOUISVILLE CLEANER AND GREENER!!
    • Tips for Recycling Metal Clothes HangersGary Barker with the Organic Consumers Association states that recycling wirehangers proves difficult for a few reasons:The hooks catch on recycling equipment causing jams and damage.There is also a petroleum polymer coating on the hangers that makes recyclingthe metal more of a challenge.Most recycling centers won’t accept metal hangers, due to the low percentage ofsteel reclaimed per hanger.If you live in an area that accepts wire hangers as part of curbside recycling, takeadvantage of it, or use Earth911 to locate recycling centers nearest you.
    • Otherwise, reuse is the best option. If you don’t want to keep wire hangersaround in your closet, use them for do-it-yourself projects such as uncloggingdrains. Lastly, many dry cleaners welcome metal hangers back to their facilitiesfor reuse.Buoyancy Why boats float and elephants sink (buoyancy) How does a boat or ship carrying hundreds of pounds worth of stuff float while that same stuff would sink to the bottom of the ocean if dumped overboard? How come when youre in a pool and you stretch your body out flat you float. But, if you wrap your arms around your legs and curl up into a ball you sink? Well, it all has to do with how much water is pushing against you and a little scientific principle called buoyancy or floatation. When you stretch out flat more water pushes against you since your body is laid out flatter. When you curl up into a ball, less water is pushing against you. Want to test this for yourself? Try this experiment: 1. Take a piece of clay and split it into 2 identically sized pieces. Take one of the pieces and roll it into a ball. Take the other piece and fashion it into a flat boat shaped object (if needed, get mom or dad to help - thats what theyre there for). 2. Now place both pieces into a sink full of water. Which one floats and which one sinks? Both? Neither? So you see, if the total area of the object that makes contact with the water is large enough, the object floats. The object must make room for its own volume by pushing aside, or displacing, an equivalent (or equal) volume of liquid. The object is exerting a downward force on the water and the water is therefore exerting a upward force on the object. Of course the floating objects weight comes into play also. The solid body floats when it has displaced just enough water to equal its own original weight. This principle is called buoyancy. Buoyancy is the loss in weight an
    • object seems to undergo when placed in a liquid, as compared to itsweight in air. Archimedes principle states that an object fully orpartly immersed in a liquid is buoyed upward by a force equal tothe weight of the liquid displaced by that object. From thisprinciple, he concluded that a floating object displaces an amount ofliquid equal to its own weight. (Note: if you dont understand theselast two paragraphs, dont worry. Theyre not on the test).Sources: World Book Encyclopedia (1997) University of Wisconsin Web Site
    • BuoyancyBuoyancy arises from the fact that fluid pressure increases with depth andfrom the fact that the increased pressure is exerted in all directions (Pascalsprinciple) so that there is an unbalanced upward force on the bottom of asubmerged object. Since the "water ball" at left is exactly supported by the difference in pressure and Index the solid object at right experiences Buoyancy exactly the same concepts pressure environment, it follows that the buoyant force on the solid object is equal to the weight of the water displaced (Archimedes principle). Objects of equal volume experience equal buoyant forces. Applications of buoyancy. Go BackHyperPhysics***** Mechanics ***** Fluids R Nave
    • Equal Volumes Feel Equal Buoyant ForcesSuppose you had equal sized balls of cork, aluminum and lead, with respectivespecific gravities of 0.2, 2.7, and 11.3 . If the volume of each is 10 cubic centimetersthen their masses are 2, 27, and 113 gm. Index Buoyancy Buoyancy conceptsEach would displace 10 grams of water, yielding apparent masses of -8 (thecork would accelerate upward), 17 and 103 grams respectively.The behavior of the three balls would certainly be different upon release fromrest in the water. The cork would bob up, the aluminum would sink, and thelead would sink more rapidly. But the buoyant force on each is the samebecause of identical pressure environments and equal water displacement. Thedifference in behavior comes from the comparison of that buoyant force withthe weight of the object. Behavior of sinking objects Go BackHyperPhysics***** Mechanics ***** Fluids R Nave
    • Archimedes Principle Hmm! The crown seems lighter under water! The buoyant force on a submerged object is equal to the weight of the Index liquid displaced by the object. For Archimedes water, with a discussion density of one gram per cubic Buoyancy centimeter, this concepts provides a convenient way to determine the volume of an irregularly shaped object and then to determine its density.

    • Archimedes PrincipleThe buoyant force on a submerged object is equal to the weight of the fluiddisplaced. This principle is useful for determining the volume and thereforethe density of an irregularly shaped object by measuring its mass in air and itseffective mass when submerged in water (density = 1 gram per cubiccentimeter). This effective mass under water will be its actual mass minus themass of the fluid displaced. The difference between the real and effectivemass therefore gives the mass of water displaced and allows the calculation ofthe volume of the irregularly shaped object (like the kings crown in theArchimedes story). The mass divided by the volume thus determined gives ameasure of the average density of the object. Archimedes found that thedensity of the kings supposedly gold crown was actually much less than thedensity of gold -- implying that it was either hollow or filled with a less densesubstance. Index Buoyancy conceptsExamination of the nature of buoyancy shows that the buoyant force on avolume of water and a submerged object of the same volume is the same.Since it exactly supports the volume of water, it follows that the buoyantforce on any submerged object is equal to the weight of the water displaced.This is the essence of Archimedes principle.

    • Current Viable Solutionshttp://morfis.wordpress.com/2010/11/19/futuristic-floating-dwellings/This is an article about the MORPHotel, a concept by Italian architect Gianluca Santosuosso it isa floating living space, however these are very complex structures so it’s a little different thanour project. The article isn’t very specific about the design of the dwellings, so maybe there arethings that can be applied to our design.http://www.holcimfoundation.org/T1228/A08AMngNG-prog10.htmThis article is about floating dwellings in a small village near Lagos, Nigeria. These dwellings, likeours are made mainly out of recycled materials. This project also launched a nonprofit businesscalled Hope Floats Initiative that we could use for our project. The team used recycled wood,plastic foils, used sheet metals, reeds and thatch.Using ideas other people have come up with is great to work off of in our own project. They canhelp us understand what we know works and what we know doesn’t. From this we can comeup with bigger and better ideas.CalculationsProofFriday, February 04, 20111:12 PMρ= density. Fresh water is 1000kg/m^3 Salt water is 1022 kg/m^3Let us assume that because there will be more molecules in any given cubic yard of floodedwater, then the mass will be greater, as is seen in freshwater to saltwater. So in a floodzone, thewater will have topsoil and other such minerals which will increase the density of the water.With this assumption there is now an ability to estimate the density of this dirt saturated water. The density of a tightly compacted cubic meter of average soil is 2002 kilograms/m^3. A rough estimate of the density of the water places the dirt to water ratio around 1:5. now, the approximate density can be calculated.
