From: David Roberson … my main concern with the induction cooktop is the mismatch between the heating coil and the typical shape of the fuel cores. If researchers change the form factor of the fuel into a planar design … then that issue can be somewhat resolved.
Dave, one more thing I keep forgetting to bring up… think of the induction cooktop as a potential substitute for the ultrasonic transducer. The first patent granted on these things talks about ultrasound (GE invented them). If the fuel could be arranged as a nanoporous solid of nickel powder and other ingredients, so that internal compression of the core forces cavitation. These cooktop operates in the same ultrasound range as sonofusion, even though the waves are nominally electromagnetic, rather than phonons. The result can be effectively the same. As for shape - configuring the fuel core as a pancake is possible. This would mean that hydrogen release must be more gradual - high pressure is avoided, and of course and that means that a moderate temperature not be exceeded. A temperature can be chosen which is near the hydrogen release temperature of TiH2 – somewhere around 300C after the gain has kicked in. Look at it this way – there is evidence in the literature that ultrasonic cavitation is effective for LENR – as well as the Letts/Cravens magnetic effects - and the induction cooktop could be providing both ! This is including a strong power level exceeding a kilowatt, which is more intense than most piezos. So there could be two advantages to this as a power source – magnetic waves combined with ultrasonic cavitation. There are papers on ultrasound in solids - in the literature, but none which include the aspect of LENR. The key could be creating a molded fuel which is a nano-porous pancake disk – which is a nominally solid fuel mix, but which is ductile enough to allow internal cavitation due to nano-porosity, but with slow hydrogen release. This seems possible… but would require a lot of engineering.
