Salutations,
Here's my last 2022 drawing providing an overview on IH aspects of some long reflection that still causes me immense regrets today, especially because of the potential remaining to realize:
The image itself still contains errors, it was mainly intended to fuel eventual discussions that never started, unfortunately. At best 2 or 3 rare braves would politely argue they feel intimidated while the rest will promptly express their displease through a typical consumerist reaction, always in extremely vague terms nonetheless.

A brief search on Google tells me that we now have an option to acquire non-rechargeable batteries capable of providing about 3.6 Volts @ 2600 mAh in 14500 format, which amounts to a grand total of about 7.2 Volts x 2.6 A = 18.72 Watts in peak burst mode. So if we account for energy conversion losses, say 15%, then that's 85% of 18.72 or 15.912 Watts (max).
Let's round it up to 15.9 Watts trying to estimate warm-up time, i.e.: 100 Joules ÷ 15.9 Watts ~ 6.3 seconds for a single Hybrid Core (made of a « susceptor » sandwiched between a pair of SiC layers), or else 12.6 seconds for my 200 Joules LAVACapsule design. All fitting into the volume of King Size cigarette packs...
Too bad today's rechargeable cells continue to cap under 900 mAh, which would stretch the preheating time by a factor close to 3. In other words we'll need to wait for energy densities to increase before such novel idea becomes viable from a user's point of view - who by the way will certainly refuse to pay $40/2 cells, not to mention those got to be rendered suitable for power applications lasting at least half a minute just to guarantee a reasonable safety margin.
M'well, lets not despair: « It's already been done before, just not yet!! »...

My previous drawings mentioned the use of magnetic flux concentration to compensate for my previous aerial windings, i'm talking about raising the bar to 18 poles in a double-sided version instead of only 1 for an air-core selenoïd whose single field is only aligned to its central axis. In comparison, the transition to 3 dimensions should greatly increase sensitivity to microphonic effects (in the presence of permanent magnets, illustrated in blue). Not only would a pair of Hall-Effect current sensors help to implement effective over-current protection, in addition their galvanically-isolated analog outputs can provide an I•Q signal suitable for synchronous quadrature demodulation, e.g. quite enough to capture tap-commands given directly through the consumption tool itself, hence without any need for other buttons - nor even any display or LED for that matter, since one may also assume this could make it possible to induce audible vibrations into that very same handle-shaped tool. In other words i foresee some novel solution suitable for a group of customers ignored by an industry where it's expected of all clients to have equal ease to use their visual & tactile/manual capabilities.
Finally, since the laws of dame Nature are immutable, it becomes imperative to make the most of these starting with this simple formula:
Considering the mass of an IH heating element never varies and we totally control the amplitude of power pulses this implies that such technology will someday allow designers of the future to precisely dose the amount of energy in plain accordance with a desired « workload » size for each inhalation, thus offering individual consumers a real opportunity to multiply their chances of experiencing something other than just systemic dosing abuse as with the "joint" which we tend to finish until the end. In conclusion, do more with less!
The bets are open. How long do we still have to wait to witness the future come true??
Good day, have fun!!
