Science Buddies: "Ask an Expert"

Hey,

I am doing this project for my science fair.
And, I just have a few questions relating it if you don't mind.


1) Is there a possibility that one could use the voltage produced from the Seebeck effect to light up a LED?
Or anything at all? *I know for sure light bulbs wouldn't work because they would require much more volt than a LED....


2) Is there anything else I can add to this project ? If so, please specify.

Thanks a lot!

Hi Envious,
Sorry for the delayed response.
1. Not really. It's possible to power an LED that's extremely small, think kind of the fiber optic type application where you can use light to do switching / computing. However, nothing that can be used for illumination like a light.

2. I would suggest the topic under the "Make it your own" section of the experiment. You may also want to look at some of the standard thermocouple metal configuration and see if there's a combination of material that peek your interest.
Here's an example for your reference.

Good Luck!

Hey LeungWilley,

I am doing this project for my science fair.
Other than changing the temperature of the liquid, we (my partner and I ) haven't done much.
We also tested the voltage produced in water with diff. salt concentration - using distilled water, tap water, and salinated water. Because of the high amount of electrolytes in salinated water, it produced more Voltage.

What else could we do? We're stuck at the moment.
Anything would be helpful.
If you could please tell me the procedures, I would greatly appreciate it.

Thank you for your time.
Hoping for a well-descriptive answer.


Thanks,
Envious.
