For 1 MW, the surface needed shall be 330000 cm² ... 33 m². With a thickness of 100 µm, we arrive at 3.3 dm³. It's not costly indeed for the benefit it has.
I'm more worried about structural body, loss heat, and control it will imply with such lower power density. That's engineering. -----Original Message----- From: Jones Beene [mailto:[email protected]] Sent: vendredi 17 août 2012 17:44 To: [email protected] Subject: RE: [Vo]:Stunning slide from Technova -----Original Message----- From: Arnaud Kodeck > With Celani, the experiment shown at ICCF-17 reaches around 3W/cm² which is very good in itself but not enough for a commercial product. Why do you say that 3W/cm² is not enough for a commercial product ? We are talking about an alloy that costs only $20/kg (US) in large volume lots.
