#REDIRECT [[Open Source Portable Forced Induction Thermoelectric Solid Fuel Stove]]
*TECHS for short
*A Device Similar to the "Biolite" stoves
*EXCEPT that it is maintainable, modular, (and perhaps better preforming (don't boast this till we can) )
 
=Industry Standards=
==Biolite==
===Biolite Campstove 1 and 2===
*The backpacking marketed one
*[https://www.bioliteenergy.com/products/campstove-2]
 
===Biolite Basecamp===
*Marketed for barbecues (the northern usa definition of the event with burgers etc, not the southern usa definition of a type of smoked food...), and was sold in a similar form as a smokeless stove, and low level energy source for underdeveloped areas
*[https://www.bioliteenergy.com/products/basecamp-pizzadome-bundle]
 
===Biolite FirePit===
*Uses the fan to make a smokeless fire pit
*DOES NOT have a teg module, and is thus battery powered
 
=Existing Open Source Design=
*Various teg desings (these tend to be of the lesser quality DIY/LIFEHACK type spam etc)
 
=Minimum Viable Product=
*3 Models:
**Soup can/standard biolite design size
**Rocket Stove Size
**Log Sized (~3 logs perhaps?)
*ALL MODELS have the TEG (the log sized biolite one DOES NOT, may be an advantage
*Perhaps devise method of removing ash better?
*Power Unit is modular, so betteries dieing do not "brick" the unit
*Fan mode adjustable from off to power generating minimum, to max heat/burn (perhaps even Solid Fuel Wok level, may be another good market (food enthusiasts) )
*Arduino nano perhaps (as simple control as possible)
*As many TEGs as possible to maximise the electricity generated
*Perhaps use the air inlet/fan as an air heatsink (at least partially) for the TEGs to preheat air, and cool the "cold side"
*Optional ceramic hearth (either ots or even printed with the [[d3d ceramic printer]] (Shatter risk, but increased heat retention and tolerance
*Uses the [[OSE Modular Battery]]
*Either a usb, or a car style barrel jack for DC output
*User buildable, and maintainable
*Ruggedized (won't rust, can handle some water (can't be submerged, but splashes and rain) , shock protection (may rule out ceramic, but if it's modular...) ) for backpackers etc to be able to ACTUALLY use it
*The modularity may lend itself to backpacking etc too due to being able to "spread out" the weight amongst packs (and not bring what you don't need)
 
=Basic Design=
==Frame==
*Welded stainless steel? Strong Plastic?
 
==Hearth==
*Either some sort of metal (most likely stainless steel), or ceramic (would lining with high temp mortar/cement work?)
 
==Fan Module==
*Small, yet powerful bldc motor?
*Needs to have high efficieny low speed capability, and relitivly high flow modes
*CAN drone motors etc do low speed (especially efficiently?)
 
==Control Module==
*Arduino nano, or a some other VERY small board of some sort
*WIFI and all that is not needed, and would just take up space and power
*Thermal Probe for hearth, air intake, and both sides of the TEGs (and perhaps ambient?)
 
==Battery Module==
*Not really needed, but some may want an integrated battery instead of an external one
*Make it a clip on module that goes over the power output?
*A simple supercapacitor, or nothing would work for most use cases (smooth out the variation, especially if a cheap power unit is used, yet not add mass/space
 
==IO==
*Indicator LEDs
*On/off switch
*Dial for modes?
 
=BOM=
==TEGs==
*Which is best for high heat combustion and air cooling?
* '''Needs more research'''
 
=CAD=
*
 
=Code=
*Should essentially be a relitively simple thermostat of sorts, along with leds for various data, and the different selectable "modes"
