Re: Physical Science Lab
1.9 volts on high and we did it by making a cd fan.

Re: Physical Science Lab
how do you get 1.9 volts
our max was like 450 micro volts or something

Re: Physical Science Lab
It all depends on the fan. Some fans can get up to 2 or 3 volts and some can only get max 1 volt with a good windmill, so its hard to compare (for instance you could get 1 volt on one fan and 2.5 on another with the same windmill)

Re: Physical Science Lab
okay but what are some of the effective blade designs to capture all of those volts
we used a four bladed laminated paper design
which was the best one we had in total it only got 800mv
what is a good blade design for this

You understated yoyosciencekid23, especially since you were unable to test it with me, it was 479 on high and 288 on low power.yoyosciencekid23 wrote:how do you get 1.9 volts

Re: Physical Science Lab
i heard that a blade design out of cd's might work pretty well
any thoughts

Best at PA was 800-something I think, so 1.9 volts would probably do very well at nats.
