PostSubject: New renewable energy source?????   Mon Apr 04, 2011 10:12 am

OK in one of my classes we have this proect. Well here is the problem statement.
Quote :
2011 ASME Student Design Competition
H2Go: The Untapped Energy Source?
Green energy is being used more each day. Wind turbines, wave turbines,
hydroelectric dams, geothermal heating/cooling, biofuels and solar panels are all being
constantly improved to be more efficient and environmentally friendly. Roughly 7% of
the world’s energy is currently generated from these sources
[http://www.eia.doe.gov/fuelrenewable.html]. However, there is a green source of
energy that has not yet been fully tapped ‐rain. The potential energy of 1 inch of rainfall
on the average single‐story house, if captured at the roof height provides approximately
120 kJ of energy, even more if the rain can be captured in motion. Devices to convert
and store this energy could be created and an untapped and readily available energy
source utilized. In addition, the water itself could be stored for a variety of everyday
uses.
Your challenge is to design a scaled, proof of concept prototype for rain energy
conversion. Your prototype device will propel a model car as far as possible in a straight
line by converting the potential energy of one liter of water at one meter height. All
water must be contained within the device and a penalty will be assessed for any water
spilled.
Course Description
At the competition, a funnel will be provided (1.5 L minimum volume within the
funnel body) with a 1.5 cm +/‐ 0.25 cm diameter opening suspended with the opening at
a height of 1 m +/‐ 1 cm. The unobstructed area beneath the funnel will be a minimum
of 0.5 m on all sides of the funnel opening.
The competition surface will be the available flooring at the contest venue. This
surface may be indoor/outdoor carpeting, industrial/commercial carpeting or hard
flooring. Contestants must be prepared to compete on any of the above surfaces, as the
contest venue’s flooring will not be specified prior to the competition.
Device Requirements
1. The only power source to be used is the 1 L of water. If any stored energy is
used in the device besides the elevated water, teams must prove that the
amount of additional stored energy after the device operates is equal to or
greater than the initial stored energy.
2. The device must have an easily removable and drainable water storage container
capable of storing at least 1.1 L of water.
3. The device must fit, fully assembled and ready to operate, within a box
measuring, on the inside, 370 x 165 x 165 mm. Any expansion or extension must
be done by the device itself during the competition run.
4. Each team will provide their own car which must:
1. Have a mass of 10 ‐ 90 gram
2. Be 25 mm to 45 mm wide
3. Be 65 mm to 100 mm long
4. Not be used as a projectile
Contest Operation
At the start signal a team member will pour the 1 L of water into the funnel. No one
may touch the device other than to pour the water. The entire liter of water must be
poured continuously in no more than 20 seconds.
At the end of the run, the water will be measured to ensure no loss.
Distance traveled will be measured using a string. The straight line distance from the
initial location of the model car to the final position will be recorded. A single point on
the car will be chosen for measuring and used at initial and final locations.
Each team will be given two runs. The second run will begin immediately after
measurements have been made from the first. The team may manually reset their
device between runs.
Scoring and Penalties
The winning device will have the highest score S where:
  

 
2
1
100
i
i i S D W
D = Distance car traveled in mm
W = Water spilled over 25 mL in mL
i = run number
Any damage to the course will result in an immediate disqualification.
Any device not meeting the device requirements will be immediately disqualified.
Judging Ties
Each SPDC must have a winner. If two cars travel the same distance (they go so far that
they hit a wall) then a runoff must be done to determine a winner. A suggestion is to go
to a venue that has more space such as a basketball court (long hallway) or a place that
has a rougher surface such as a parking lot.

Ok, i am wondering if anyone know of any model car or something that can be used for this project. or any way to start this. still have no idea how to really start making this.

We had to do a rain energy project. Biggest waste of time. We had to design a system to capture rain water energy from a roof. The payoff on the project were measured in thousands of years. It's a dumb project setup by tree hugging liberals. The future is nuclear energy.

maybe make a paddle wheel on the axle of the car so that the water flow makes the axle turn? 1L of water in a roughly 2" x 4" car doesnt seem too practical though.
