Team+SCRUB

Today we started to pt the new wheels on our car. We attached two wheels in the back on a wooden axel that was attached to the chassis with straws. Our other wheel was attached in the front "today it's sunny with a slight chance of rain with not very much clouds" says Matt, but back to the car, Nitro Dax put some wood on the car and a bumper of foam in the front. Matt dropped the wheel at the most important part but it was OK.

Depending on how well we work today. Today we successfully attached a motor, and batterys. Jessie was not here today. She will probably be here tommorrow. Now that we have finished successfully creating a solar charged car we are not being very productive on the scientific aspect of the vehicle and more on the creative side of the assignment. More tomorrow. Or perhaps not. Because tomorrow is grandparents day. Our car is really working!!!!! We put rubber bands on the car to increase the traction.

OK. I think our car is the fastest. It has some problem with steering though. We will soon burn out the battery and have to figure out our whole solar thing.

Our car had a problem with the smaller gear on the motor coming away from the Bigger gear on the axle, but Nitro Dax and Matt solved the problem by attaching a rubber band that pulls the smaller motor toward the bigger one, our car is awesome! Matt's quote for the day "Rubber bands make beautiful sculptures.

We finished making a solar panel charger thing. i think it works!

ok. Our stupid car is not working because the rest of the group decided to put glue on the rivet thing. SO NOW WE ARE STARTING OVER.

we are going to make it just a wooden frame to make it more aerodynamic.

our car is crap...

not that there is anything with that ...

well there is. so now we are making a new car.

yay.  now jessie and henry are sanding dowels and matt is cutting a place for the gear.

this is going to be a stream line vehicle able to surpace speeds such as 0-5 in 6 secs! //The word energy derives from// [|//Greek//] //ἐνέργεια (energeia), which appears for the first time in the work// [|//Nicomachean Ethics//][|//[4//]] //of// [|//Aristotle//] //in the 4th century BC. In 1021 AD, the// [|//Arabian physicist//]//,// [|//Alhazen//]//, in the// [|//Book of Optics//]//, held// [|//light//] //rays to be streams of minute// [|//energy particles//]//, stating that "the smallest parts of light" retain "only properties that can be treated by geometry and verified by// [|//experiment//]//" and "they lack all sensible qualities except energy."//[|//[5//]] //In 1121,// [|//Al-Khazini//]//, in The Book of the Balance of Wisdom, proposed that the// [|//gravitational potential energy//] //of a body varies depending on its distance from the centre of the Earth.//[|//[6//]] //The// [|//concept//] //of energy emerged out of the idea of// [|//vis viva//]//, which// [|//Leibniz//] //defined as the product of the mass of an object and its velocity squared; he believed that total vis viva was conserved. To account for slowing due to friction, Leibniz theorized that heat consisted of the random motion of the constituent parts of matter, a view shared by// [|//Isaac Newton//]//, although it would be more than a century until this was generally accepted. In 1807,//[|//Thomas Young//] //was the first to use the term "energy" instead of// [|//vis viva//]//, in its modern sense.//[|//[7//]] [|//Gustave-Gaspard Coriolis//] //described "//[|//kinetic energy//]//" in 1829 in its modern sense, and in 1853,// [|//William Rankine//] //coined the term "//[|//potential energy//]//." It was argued for some years whether energy was a substance (the// [|//caloric//]//) or merely a physical quantity, such as// [|//momentum//]//.// //William Thomson (//[|//Lord Kelvin//]//) amalgamated all of these laws into the laws of// [|//thermodynamics//]//, which aided in the rapid development of explanations of chemical processes using the concept of energy by// [|//Rudolf Clausius//]//,// [|//Josiah Willard Gibbs//]//, and// [|//Walther Nernst//]//. It also led to a mathematical formulation of the concept of// [|//entropy//] //by Clausius and to the introduction of laws of// [|//radiant energy//] //by// [|//Jožef Stefan//]//.// //During a 1961 lecture//[|//[8//]] //for undergraduate students at the// [|//California Institute of Technology//]//,// [|//Richard Feynman//]//, a celebrated physics teacher and// [|//Nobel Laureate//]//, said this about the concept of energy://

//There is a fact, or if you wish, a law, governing natural phenomena that are known to date. There is no known exception to this law; it is exact, so far we know. The law is called// [|//conservation of energy//]//; it states that there is a certain quantity, which we call energy, that does not change in manifold changes which nature undergoes. That is a most abstract idea, because it is a mathematical principle; it says that there is a numerical quantity, which does not change when something happens. It is not a description of a mechanism, or anything concrete; it is just a strange fact that we can calculate some number, and when we finish watching nature go through her tricks and calculate the number again, it is the same.////—The Feynman Lectures on Physics//[|//[8//]] //Since 1918 it has been known that the law of// [|//conservation of energy//] //is the direct mathematical consequence of the// [|//translational symmetry//] //of the quantity// [|//conjugate//] //to energy, namely// [|//time//]//. That is, energy is conserved because the laws of physics do not distinguish between different moments of time (see// [|//Noether's theorem//]//).

~ http://en.wikipedia.org/wiki/Energy// //With regard to producing usable transportation fuel from solar energy, there are two systems:

• Concentrating Solar Power (CSP): in this system, reflective materials concentrate the sun's energy, creating high temperatures. The corresponding heat powers a generator which converts it to electricity.

• The advantage to this somewhat inexpensive option is that the derived power could be used in electric cars and hydrogen fuel cells. However, this system contributes some pollutants into the atmosphere because it uses fossil fuels such as natural gas.

• Photovoltaics (PV):Photovoltaics use cells (think solar panels) to convert solar energy directly into electricity.

• To that end, the advantage of PVs is that they are likely to be on-board vehicle power sources with zero emissions. The chief disadvantage is that currently, PV cells are very inefficient, capable of converting only about 15% of the solar energy they receive into electricity.//

Today we finished the frame and added the dowels and because i have nothing else to say on the matter of our car i have decided to post more informational pieces from wikipedia and the like...

// Solar chemical processes use solar energy to drive chemical reactions. These processes offset energy that would otherwise come from an alternate source and can convert solar energy into storable and transportable fuels. Solar induced chemical reactions can be divided into thermochemical or [|photochemical].[|[74]] [|Hydrogen production] technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2300-2600 °C).[|[75]]Another approach uses the heat from solar concentrators to drive the [|steam reformation] of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods.[|[76]] Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the [|Weizmann Institute] uses a 1 MW solar furnace to decompose [|zinc oxide] (ZnO) at temperatures above 1200 °C. This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.[|[77]] [|Sandia's] Sunshine to Petrol (S2P) technology uses the high temperatures generated by concentrating sunlight along with a [|zirconia]/[|ferrite] catalyst to break down atmospheric carbon dioxide into oxygen and [|carbon monoxide] (CO). The carbon monoxide can then be used to synthesize conventional fuels such as methanol, gasoline and jet fuel.[|[78]] A photogalvanic device is a type of battery in which the cell solution (or equivalent) forms energy-rich chemical intermediates when illuminated. These energy-rich intermediates can potentially be stored and subsequently reacted at the electrodes to produce an electric potential. The ferric-thionine chemical cell is an example of this technology.[|[79]] Photoelectrochemical cells or PECs consist of a semiconductor, typically titanium dioxide or related titanates, immersed in an electrolyte. When the semiconductor is illuminated an electrical potential develops. There are two types of photoelectrochemical cells: photoelectric cells that convert light into electricity and photochemical cells that use light to drive chemical reactions such as [|electrolysis].[|[80]

** Solar vehicles **
//[|Main articles:][|Solar vehicle], [|Electric boat], and [|Solar balloon]// Australia hosts the [|World Solar Challenge]where solar cars like the Nuna3 race through a 3,021 km (1,877 mi) course from Darwin to Adelaide. Development of a solar powered car has been an engineering goal since the 1980s. The [|World Solar Challenge] is a biannual solar-powered car race, where teams from universities and enterprises compete over 3,021 kilometres (1,877 mi) across central Australia from [|Darwin] to [|Adelaide]. In 1987, when it was founded, the winner's average speed was 67 kilometres per hour (42 mph) and by 2007 the winner's average speed had improved to 90.87 kilometres per hour (56.46 mph).[|[81]] The [|North American Solar Challenge] and the planned [|South African Solar Challenge] are comparable competitions that reflect an international interest in the engineering and development of solar powered vehicles.[|[82]][|[83]] Some vehicles use solar panels for auxiliary power, such as for air conditioning, to keep the interior cool, thus reducing fuel consumption.[|[84]][|[85]] In 1975, the first practical solar boat was constructed in England.[|[86]] By 1995, passenger boats incorporating PV panels began appearing and are now used extensively.[|[87]] In 1996, [|Kenichi Horie] made the first solar powered crossing of the Pacific Ocean, and the//sun21// catamaran made the first solar powered crossing of the Atlantic Ocean in the winter of 2006–2007.[|[88]] There are plans to circumnavigate the globe in 2010.[|[89]] Helios UAV in solar powered flight. In 1974, the unmanned [|AstroFlight Sunrise] plane made the first solar flight. On 29 April 1979, the //[|Solar Riser]// made the first flight in a solar powered, fully controlled, man carrying flying machine, reaching an altitude of 40 feet (12 m). In 1980, the //[|Gossamer Penguin]//made the first piloted flights powered solely by photovoltaics. This was quickly followed by the //[|Solar Challenger]// which crossed the English Channel in July 1981. In 1990 [|Eric Raymond] in 21 hops flew from California to North Carolina using solar power.[|[90]]Developments then turned back to unmanned aerial vehicles (UAV) with the //[|Pathfinder]// (1997) and subsequent designs, culminating in the //[|Helios]// which set the altitude record for a non-rocket-propelled aircraft at 29,524 metres (96,864 ft) in 2001.[|[91]] The //[|Zephyr]//, developed by [|BAE Systems], is the latest in a line of record-breaking solar aircraft, making a 54-hour flight in 2007, and month-long flights are envisioned by 2010.[|[92]] A [|solar balloon] is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward [|buoyancy] force, much like an artificially heated [|hot air balloon]. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.[|[93]] [|Solar sails] are a proposed form of spacecraft propulsion using large membrane mirrors to exploit radiation pressure from the Sun. Unlike rockets, solar sails require no fuel. Although the thrust is small compared to rockets, it continues as long as the Sun shines onto the deployed sail and in the vacuum of space significant speeds can eventually be achieved.[|[94]]

[|The][|High-altitude airship] (HAA) is an unmanned, long-duration, lighter-than-air vehicle using [|helium] gas for lift, and thin-film solar cells for power. The [|United States Department of Defense] Missile Defense Agency has contracted [|Lockheed Martin] to construct it to enhance the [|Ballistic Missile Defense System] (BMDS).[|[95]] Airships have some advantages for solar-powered flight: they do not require power to remain aloft, and an airship's envelope presents a large area to the Sun.]

//"Aerodynamic" redirects here. For other uses, see [|Aerodynamic (disambiguation)].// A [|vortex] is created by the passage of an aircraft wing, revealed by smoke. Vortices are one of the many phenomena associated to the study of aerodynamics. The equations of aerodynamics show that the vortex is created by the difference in pressure between the upper and lower surface of the wing. At the end of the wing, the lower surface effectively tries to 'reach over' to the low pressure side, creating rotation and the vortex. Aerodynamic problems can be identified in a number of ways. The flow environment defines the first classification criterion. //External// aerodynamics is the study of flow around solid objects of various shapes. Evaluating the [|lift] and [|drag] on an [|airplane] or the [|shock waves] that form in front of the nose of a[|rocket] are examples of external aerodynamics. //Internal// aerodynamics is the study of flow through passages in solid objects. For instance, internal aerodynamics encompasses the study of the airflow through a [|jet engine] or through an [|air conditioning] pipe. The ratio of the problem's characteristic flow speed to the [|speed of sound] comprises a second classification of aerodynamic problems. A problem is called subsonic if all the speeds in the problem are less than the speed of sound, [|transonic] if speeds both below and above the speed of sound are present (normally when the characteristic speed is approximately the speed of sound), [|supersonic] when the characteristic flow speed is greater than the speed of sound, and [|hypersonic] when the flow speed is much greater than the speed of sound. Aerodynamicists disagree over the precise definition of hypersonic flow; minimum [|Mach numbers] for hypersonic flow range from 3 to 12. The influence of [|viscosity] in the flow dictates a third classification. Some problems may encounter only very small viscous effects on the solution, in which case viscosity can be considered to be negligible. The approximations to these problems are called [|inviscid flows]. Flows for which viscosity cannot be neglected are called viscous flows.
 * Aerodynamics** is a branch of [|dynamics] concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a subfield of [|fluid dynamics] and [|gas dynamics], with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with the difference being that gas dynamics applies to all gases. Understanding the motion of air (often called a flow field) around an object enables the calculation of forces and moments acting on the object. Typical properties calculated for a flow field include [|velocity], [|pressure], [|density] and [|temperature] as a function of position and time. By defining a [|control volume] around the flow field, equations for the conservation of mass, momentum, and energy can be defined and used to solve for the properties. The use of aerodynamics through mathematical analysis, empirical approximation and wind tunnel experimentation form the scientific basis for [|heavier-than-air flight].

From Wikipedia, the free encyclopedia
The [|Nissan Leaf] goes on sale at the end of 2010 in limited quantities and to select markets, with global availability scheduled for 2012.[|[1]]The [|tzero] on the left can go up to 300 miles (480 km) at 70 mph (110 km/h) using Li-ion batteries, while the [|EV1] on the right has a range of 160 miles at 65 mph using NiMh batteries, or 80 miles (130 km) with lead acid ones. An **electric car** is an [|alternative fuel] [|automobile] that uses [|electric motors] and [|motor controllers] for [|propulsion], in place of more common propulsion methods such as the [|internal combustion engine] (ICE). Electric cars have the potential of significantly reducing [|city pollution] by having zero [|tail pipe emissions].[|[2]][|[3]][|[4]] Vehicle [|greenhouse gas]savings depend on how the electricity is generated. With the U.S. energy mix using an electric car would result in a 30% reduction in[|carbon dioxide] emissions.[|[5]][|[6]][|[7]][|[8]] Given the current energy mixes in other countries, it has been predicted that such emissions would decrease by 40% in the UK[|[9]], 19% in China[|[10]], and as little as 1% in Germany.[|[11]][|[12]] Electric cars are commonly powered by on-board battery packs, and as such are [|battery electric vehicles] (BEVs). Although electric cars often give good acceleration and have generally acceptable top speed, the poorer energy capacity of batteries compared to that of fossil fuels means that electric cars have relatively poor range between charges, and recharging can take significant lengths of time. However, for everyday use, rather than long journeys, electric cars are very practical forms of transportation and can be inexpensively recharged overnight. Other on-board energy storage methods that may give more range or faster recharge are areas of research. Electric cars are expected to have a major impact in the auto industry[|[13]][|[14]] given advantages in [|city pollution], less dependence on oil, and expected rise in gasoline prices.[|[15]][|[16]]

FIRST SOLAR CAR RACES
Hans Tholstrup and Larry Perkins were the first solar car racers who completed a Solar Trek from Perth to Sydney, [|Australia] in 1983. Next in 1986, [|Denis Bartel] drove the first solar powered vehicle named 'The Spirit of Adelaide", to cross Australia from North to South (Darwin to [|Adelaide]).
