Re: Thermodynamics B/C

I think that they are putting more of an emphasis on the estimation part rather than the heat retention.

Re: Scioly Assassination 112: The Ides of March

Glasgow was the site of the first electricity-generating windmill. Just throwing it out there. (I did Wind Power so the name was familiar)

For the record, this is division B, right?
yes, Div B

Re: Wind Power B/C

I'm also curious to know this. Also, anyone know the top voltage scores? We came in 8th with 335 on low and 593 on high. Test was also ok (@ shadow flicker lol). RestingDoll, what were your blades like in terms of the questions above? We got 5th but failed the test, got 400 something on low and 600...

Re: Wind Power B/C

Do you happen to know what the resistance was? It's changed since last year (since now the resistance can be much more), but I suppose it was at 7.5ish ohms because our blade performed better at Nats than at my home setup. Oh I see. Our turbine got about 300 mV at States but i don't know what the r...

Re: Wind Power B/C

Every competition will have different scores in terms of voltage due to differences in motors/fans/resistance. As long as you do relatively well compared to others, you should be fine. Specific to last years nats, I think 1st place got 650 mV on high power and 450 mV on low power (check old forums)...

Re: Wind Power B/C

What would be considered to be a "great score" for blades in millivolts for Division C, given that a good score would get you placing in the top 10 in nats? I know things have changed since last year, but I kind of want to get a better estimate of how I (belatedly) did last year and what to improve...
