It wows me and I like to see it in action. I'm just having a very hard time imagining it working on a larger scale and in situations where consistency are needed from roast to roast over years.

Once the roaster heats up, the roasting drum stays at a consistent temperature throughout the day. Much like a gas roaster, the temperature does drop when 30lbs of green are dropped into the drum. However, the second charge is quick, with temperatures leveling back at the desired temperature. It seems that with all new things, there are those who are naysayers. With this project, we have moved to a sunny city, with a dependable FREE ENERGY SOURCE. The sun is brilliant, and the coffee is great. Cheers.

I mean adding 30lbs green coffee beans to a hot drum cools it down dramatically. So maybe i should be asking, how powerful is the solar panels? Then on top of that how consistent can it roast? Will it roast cooler on cloudy days (Long roasts on cloudy days and very short roast on clear sunny days)? Will you be able to roast during monsoon season? We strive for consistency in the cup in this industry. To rely on this machine to do that when it relies on one of the most inconsistent things we live with, the weather, seems like not such a wise decision. Maybe as a back up roaster on "good" days it might be worth it. I wonder how temperature stable this system is? I mean adding 30lbs green coffee beans to a hot drum cools it down dramatically.
