Our Invention


Our invention is a solar powered car. The solar powered car is basically like a regular car, but it has been changed and the engine and motor are attached to a solar panel. It is pretty cheap, and it sells for only $2,000-4,000 more than a regular car. Here is a video of our car in action

Introducing...the Emcar!

1.1 Information Of Problem-Summary of Project


Our group consists of Nicole, Nellie, and Jacqueline. We have chosen solar power as our renewable energy. We all believe that solar energy is a great and efficient way to power our stuff. We make think solar energy is a great way to power up things because it helps the environment also known as, saving energy.

1.2 Information Needed- Questions




1. Why isn’t everything solar powered? Shouldn't they have put a solar panel on everything by now?
Everything isn’t solar powered now because it is too expensive. Also, sometimes something (like a car) consumes too much energy to be totally solar powered. http://wiki.answers.com/Q/Why_isn't_everthing_powered_with_solar_energy

2. How does the solar energy get absorbed into the cell?
Older solar technology uses large crystals made out of silicon, which produces an electrical current when struck by light. Silicon can do this because the electrons in the crystal get up and move when exposed to light instead of just jiggling in place to make heat. The silicon turns a good portion of light energy into electricity, but it is expensive because big crystals are hard to grow.
Newer materials use smaller, cheaper crystals, such as copper-indium-gallium-selenide, a compound semiconductor material composed of copper, indium, gallium, and selenium, that can be shaped into flexible films. This "thin-film" solar technology, however, is not as good as silicon at turning light into electricity. http://www.scientificamerican.com/article.cfm?id=how-does-solar-power-work

3. Why was solar power invented?
Solar power was invented because people needed a more efficient way to power things. It was discovered in the middle of the big oil crisis in 1970’s, because we needed a renewable way to power things. http://wiki.answers.com/Q/Why_was_solar_power_invent

4. How does solar power compare with coal power?
Solar power is efficient and dependent on sunshine, and although much of the USA is quite cloudy during certain times of the year, solar power can power a lot of things in a cleaner way. Coal is far lest costly and reliable , but it is inefficient and pollutes our planet. http://wiki.answers.com/Q/What_is_the_relationship_between_coal_and_solar_power

5. Why are solar powered things usually expensive?
Solar Powered things are usually expensive because it helps save energy. Also there is not a lot of silicon (which solar panels run on) but there is a lot of coal. http://www.solarpoweristhefuture.com/why-are-solar-panels-so-expensive.shtml

6. Why should people buy solar powered things?
People should buy solar powered things because it helps the environment.Not a lot of people buy it though because when you buy solar panels, they cost a lot of money. This is because there is not a lot of silicon. http://www.articlesbase.com/environment-articles/why-more-people-should-buy-solar-panels-556703.html

7. How much more efficient are solar panels than coal power?
So far solar photovoltaic panels have achieved max: 20 % efficiency. Although they are not totally efficient, they are getting better day by day, where as fossil fuels have failed to get any efficiency. http://solar.calfinder.com/blog/solar-information/coal-power-vs-solar-power/

8. Who invented Solar panels? why?
Check out __http://www.eia.doe.gov/kids/energy.cfm?page=solar_home-basics__
1839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develope when light fell upon the electrode.

9 How many people use Solar panels?
It is estimated that only .1 percent of the United States' electricity and power come from solar panels and solar energy, which is hardly enough to make a difference in the amount of fossil fuels used. http://ezinearticles.com/?How-Many-People-Are-Using-Solar-Panels?&id=341159
10. What is a solar cell?
A solar cell is a panel that absorbs sun light into the cell and help create energy to power up electric devices. http://en.wikipedia.org/wiki/Solar_cell

2nd Set
What is the photovoltaic effect?
The photovoltaic effect is an method to create voltage, and to build up voltage between two different bands of a material.
Why are silicon crystals so hard to grow to form solar panels?
Silicons are hard to grow because they have an very large mass, and it is hard forming with covalent bonds, which is an form of chemical bonding between electrons and atoms. That is why though silicon panels work, it is hard getting the crystals and the electrons to get together.
Can you see the solar cells turning into light?
Using the photovoltaic effect, yes. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.
Why do certain things react with light?
The crystals in the thing, such as silicon, reacts to light, gets up and moves, thus turning into an electric current.
How big are solar panels?
It depends, from big ones for buildings, to small ones for toys.
How do photovoltaic cells covert light into electricity?
First, electrons are emitted from matter, like silicon, because their absorption of light, and then go through an electric current.
What is CSP?
CSP is concentrated solar power , and they use glass or lenses, to absorb an large area of light into an smaller one, and electrical currents are produced when the concentrated light is converted to heat, which drives an heat engine, which is connected to an electric power generator.
How did Charles Fritts invent the solar cell?
Charles Fritts coated selenium with an thin sheet of gold. It worked, but not very well.
How much do solar panels usually cost?
If it is an big one, probably $30-40,000 , but if it is an small one, probably $15 or $20.
What are photons?
It is a particle representing a bit of light or other electromagnetic radiation. It carries energy just like to the radiation frequency except it doesn't have any rest mass.

2nd Set questions are all found in Wikipedia. (Silicon, Solar Panels, Solar Energy, CSP)
We've decided to present the 1st Set of questions.

Scratch Project

6.1/6.2 Judge The Product and Judge the Process


We did well on the product, and here's a list of the advantages and disadvantages.
Advantages: Disadvantages:
6.1/6.2

Group:It is a toy and in reality, you can’t really drive it. It is rather fragile and cannot power that well on foggy days. It can also work by very strong flashlights.

Nicole: I think it is a very cool toy for kids. The advantages are that it can power up with strong flashlights and it saves up energy. The disadvantages of our product is that it won’t work on foggy days and you it doesn’t come with an controller.

Nellie: I think that this is a really good toy car because it will never run out of batteries unless its a dark or foggy day. The disadvantages are that when it runs out of solar when its in the winter or on dark days.

Jackie: I think its a really good toy car because it actually works. But the disadvantage is that it is too fragile

Others: It is made of lego and can actually work
