Bellwether Roaster
renatoa
Surely is BS because it simply breaks some thermodynamic laws...
The specific heat of green coffee was found to be around 1400 J/kgK, at room temperature, with a steady rise up to 4000 J/kgK until 120°C up, with a return to the start value about 245C degrees. So an average of about ... say 2400 J/kgK.
A Joule is one watt per second, thus 2400J / 300 Watts results 8 seconds required to increase the temperature of one kg of greens by one degree, using 300W, as stated...
To bring the beans into FC, at 200 C degrees, you need 8*200 = 1600 seconds = more than 25 minutes!
In very ideal conditions, no losses...

"To prove the possibility of electric, distributed roasting, James asked to do something that had never been done before – become the first person ever to roast coffee using sunlight by harvesting a day’s solar power and connecting it to a Bellwether Roaster. "

At present, China manufactures over 90% of the worlds solar panels. Toxic waste from the manufacture of and later disposal of solar panels is believed to exceed all other energy forms including nuclear. In addition, China is up to its old tricks of using forced labor for capture and processing the raw materials as well as in the manufacturing process.

They seem to expend more effort in proclaiming how "sustainable" this roaster is than telling how well it roasts coffee! Looks like if you sign up for their program, you'll also be getting their "sustainable" green coffee from "sustainable" coffee farms.

If anyone is interested in discovering the new age occult religious roots of the current sustainability movement, I've placed a document in our downloads section titled (Nefarious History of the Sustainability Movement). I've been studying it and the organization that created it for many years. I think most people would not believe it's dark roots unless they saw it for themselves.

Interesting machine, although I can't find any videos of it roasting in a real-world scenario.

There does seem to be nothing out there on this machine. I even searched Sébastien El Idrissi's site who did at least the basic overall design and no links to anything else I can see.

Another interesting thing is Mikafi deciding to use a model designation (MCR 1) that was already in use by Mill City Roasters
