Electric Motor
Grahm siad that we would need about 7kW to power our car.
If that is a good amount of power then keep in mind that electric motors are rated by how much power they can make constantly for a long period of time. A motor that is rated at 7kW might use less than 7kW most of the time while the car is cruising. Also a motor rated at 7kW should be able to produce at least 1okW of power for short bursts (acceleration). The only thing that stops the motor from producing 1okW of power constantly is overheating. So if we want to save weight and money we might be able to use say, a 5kW moter that can produce 7kW under accelleration.

NEW TEAM NAME!!!
Alright guys...this is it. We finally chose a team name! :D
GREEN ENERGY TEAM
or G.E.T.
So we hope that each team member can come up with some kind of design for this logo, and by next week we can decide on a final idea. I myself have some cool designs and I'm looking forward to sharing them with everyone! See you guys next week!
http://www.logomaker.com/ is really useful for coming up with ideas that we can build on. To log in on Logo Maker use the user name: reducethejuicewci and the password: reducethejuice . If you save the logo when your done then others can see you ideas as well as edit them and save them as a new logo. If you know how to use HTML then you can use free web logo button to get the code to insert the logo on the blog. Don't put the logo on the blog in any way other than pasting the text in though because any other way is ILLEGAL according to the terms of service.
Here is one idea I think might work:
(this is designed for a white background,look at it in the blog editor)

Solar Panels Energy Information and Cost
In order to have our car accelerate at "x" metres per second, than we must have xy watts of power, where "x" is the acceleration and "y" is the mass of the car in kilograms. With the batteries we're going to be sticking in the car, we will likely end up having a mass of about 1000 kg. Also, a good speed of acceleration would be about 7 metres per second, therefore making it so that we need 7000 watts to power our car, or 7 kilowatts. 7kW = 10 horsepower
Retail price for solar cells are currently running at 4.85 US dollars per watt. This makes it so that it would cost $33,950 to buy enough solar panels to constantly run the car. However, with batteries, it would be z=xy, where "z" is kilowatt hours, "x" is kilowatts the solar cells can generate, and "y" is time the cells are charging. I am not sure how long we want our car to run for, but if it is, say, 1 hour, than we would either need to charge $33,950 worth of solar cells for one hour, or $16,975 worth of solar cells for two hours, or $11316.67 worth of solar cells for three hours, etc.
NOTE: If we are able to get a sponsorship from Arise Technology Information, than they might either give us solar cells at a reduced rate for one of their solar cell projects.

RTJ Website
Hey Everyone!
I've linked this blog to the RTJ site www.reducethejuice.ca (it may take a few days to show up though). You should all check it out, and let me know if anyone thinks of cool ideas to put up on the site - send me as much as you can!
See you all tomorrow!

Another Car Site
This car building site seems to be a great model for us to reference. Project designs, processes, philosophies, videos, sponsors etc...are all posted on the site.
