Electric Heater using Light Bulbs as Heat Source-French Patent

[lancaIV]

Skywalker,  when you enter the Google  Lydie Gricourt patent site you will see several references, also another french patent FR2620519, from this you should expect for a bad insulated,  windy,  room with 250 sqft area andestimating 2,4 mtr. wall high 1500 Watt thermal energy need.Google search : Mark Harris, Voltage syntheziser, each 110 Volt string to transformer--------------All your experiments and measure results are not a lost : it is theory/practise experienceYou wrote about 35°F~ 1,7°C, here GB2203529 an ambient dehumidifier( enthalpy energy gains) and space heater
from 0° C to 15°C space warming (against condensation temperature, which bad for textile and rheumatism)like a "candle heater".

It's very simple - when you keep resistive heating wire at constant temperature it has also stable resistance - depending on material. Then in resonant tank circuit and with some electronics you can keep the current circulated with a little input. Pure resonance. Of course it's all theoretic because I didn't made a working prototype. But I don't see why it would not work - the main problem with heaters or lights is their filament resistance is variable - if you find a way to make it static you can limit input current.

A solution to your problem I highlighted above is to use a zero or near zero temperature coefficient resistive wire for the heater. See this link as one solution:  https://en.wikipedia.org/wiki/Manganin 
Probably the resistive wire used in hair driers, bread toasters etc also has a low temp coefficient (I do not know for sure), you can check it by measuring the DC resistance just after the moments you unplugged them from the mains (after 1-2 minute run time).

For an interesting patent application on induction heater for residential buildings, see German application DE202014001838 I mentioned it here a few minutes ago:  https://overunity.com/17861/bifilar-pancake-coil-overunity-experiment/msg526586/#msg526586

Exactly. I would prefer https://en.wikipedia.org/wiki/Constantan but in fact any resistive wire has some range of parameters where its resistance can be keep stable.

Hi all, Been working on designing and building a heater based on this french patent.
It will use 32 - 100 watt incandescent bulbs.
8 bulbs in parallel on each branch and 4 of these parallel branches in series, using 120 volts ac.
It will have an enclosure and a small fan for forced air convection.
Comments welcome.
peace love light
