a solar powered oven works by getting sunlight in through it clear part. it guides the solar beams to the specif part making it cook. I don't know if this is right but thats what out science teacher tells me.

science teacher Answered:
A solar oven cooks by concentrating the sun's rays. The inside of the box is reflective and reflects the rays back to the center to hit the food. The cardboard box acts as an insulator to keep the heat in.

The project is not too simple if you follow the lab format and show the purpose, the materials the instructions, the observations and the conclusion.

There's a LOT of sites on google.
http://solarcooking.org/plans/ has pictures. plans are on a nearby link.
http://www.builditsolar.com/Projects/Coohas more links, 1 sort of looks like a pizza box (http://www.home.ix.netcom.com/~jdhowell/ but I think the bigger shiny area of other plans might work better. Oh, this isn't an oven, more like a cook top. (it heats a metal pan).

This is not a kiddish topic,cooking without using firewood or charcoal would help the environment in many areas. And help people save money too.

Industrial engineers could design more efficient procedural flows at any/all levels of the process.You could ensure that waste is minimized.Also, work stations can always be improved.

Logistics – the transfer of materials from one point to another such as building materials as well as things like power lines.

Ergonomics – putting into practice the best ways for things to be put together so that it makes for ease of use, ease of assembly or disassembly, ease of integration of new and old devices and technology into current and future projects.

Operations Research – study and application of systems of equations to determine the best use of resources.

Time Studies – use of systems such as MOST to determine current periods of time to complete certain operations and to find areas for improvement.

The above are some examples of how an indsutrial engineer might be able to work in the field of renewable energy. As renewable energy is relatively new area of development, all fields of engineering are open to assistance in this particular field. One trend with this particular field might be to think that its goal is to produce renewable energy that it focusses completely on the new technologies used to produce the actual energy we are going to use.

Consider the situation of a new company getting into renewable energy. They only have so much money to invest. If they do not focus on the right things or their predictions of what will work and what will not work are off or incorrect, they will have less money to work with in the future, both revenue and capital.

An engineer looking to get into this field would benefit from coming up with their own ideas about what they can do but should also talk to people currently in the field to find out what their needs are. Talk to as many people as you can, both engineers and non-engineers including manual labourers. You can look into programs being offered at schools at the university level and community colleges. Work on talking to people whom have been involved in new "green" buildings as well as other areas of industry such as production of pulp and paper. There is no limit to where renewable energy can be applied, just limits on where the people in charge want to focus their energies.

Consider the transfer of old power production technologies to new power production technologies. There must be a lot of room for an engineer to do work in that area. Brainstorm for both new ideas that nobody may have thought of as well as areas that people are currently working on.

You may just have to question your political soul.You are obviously what I would consider a wacko leftist, but you probably consider yourself thoughtful and open.The Hockey stick graph has been modified a number of times due to improper data, improper formulas mining the data for hockey sticks and exaggerating certain data to show a hockey stick.For example, what Mann did was check the data for correlations with modern warming and those proxies that showed correlation were greatly exaggerated by the formulas.They used a proxy from Bristlecone pines and related species that were extremely flawed.Their hockey stick broke when these flawed proxies were removed.I don't agree with everything they said.Humans have emitted enough to increase the concentration of CO2 in the atmosphere by about 150 ppmV (parts per million by volume).The CO2 has increased only 100 ppmV in the last hundred years or so but that is not a firm number.The CO2 concentration is based mostly on ice core data that is flawed and limited but alarmists treat it as gospel.Solar flares don't account for spikes in temperature but sun spots and there number do show some correlation to warm and cool periods historically.The exact reason or mechanism for this is unknown.It may be from variation in solar output and varying magnetic field strength.Water vapor may be 40 times as concentrated by CO2 per molecule has a greater effect.Water vapor can be up to 4% but CO2 is about 400 ppmV.I don't know where that 40 per cent came from.Clearly water vapor is more important.Alarmists depend of CO2 increasing H2O.Without that increase of water vapor, CO2 isn't all that much of a threat.

You can't go wrong with a nice presentation board, a slideshow, or a speech, if you do it well. How are you expected to show this?

Also, try to put in enough FACTS and COMMENTARY or EXPLINATIONS to keep it balanced and smart.

Try to keep it illustrated with stuff that's not too flashy, and VERY relevant to your topic.

If you do a speech, SPEAK UP! Make it sound like you KNOW what you say, and make them think you're an EXPERT. You don't really have to know it off the top of your head, but if you choose to, use SMALL CUE CARDS.

Just make it look smart, cool, and trustworthy, and you're good. (Unless you forgot to research it.)

Light Knight Answered:
1st Q:
No solar power does not need a special kind of light.However different photovoltaic cells respond better to different parts of the spectrum.

2nd Q:
Yes you could use a light wave outside of the visible spectrum, if the photovoltaic cells can handle it.
Some of the earliest photocells were tauted as being able to make electricity from the random radiation given off from radioactive material.
