Yes that's why I'm considering a supercharger type of positive displacement blower.

I know it doesn't take much power to lift an hovercraft barely above flat ground. Thats exactly what I want to do. My problem is with the dimension of the hovercraft. The smaller it is, the more power it requires for the same weight... "SIMPLE! Just make it bigger!" That's exactly the opposite...

Thank you but I am actually looking for something smaller

Yes! That would be right! Well... I'm just the average Joe and I may be wrong but that's what I believe would be right! Haha

Thank you very much for the reply! Actually, I'm not even sure if the minimum cfm for my device to work would be 400. In fact, I just based this requirement on an observation from some experiment seen on youtube. Since you've been kind enough to take the time to answer me, I'll reveal a bit more...

To my understanding you have: - 1 bulb requiring 0.3 Amp at 1.5V You want to figure how many batteries to power it. - Batteries giving 1200 mAh at 1.5V Since 1200 mAh = 1.2 Amps/hour Then with only 1 battery you could power your bulb for 4 hours: 4h × 0.3amps = 1.2 amps/hour (1200 mAh)

Hi! I'm trying to figure out what kind of specs a small electric motor would need to power some small "positive displacement" blower. According to my design, the total amount of space in the chambers would be approx 50 cubic inches (0,0861 cu feet). Then to reach a required 400 cfm it would...
