so ive got an idea for you. do you remember those old fashioned pinball machines from the forties? you drop pinballs and watch them drop down the ramp full of pins bouncing around? what if you had a stainless steel ramp full of pins that was the right length and number of pins to keep a bath of beans falling down it for 9 to 20 minutes. maybe a small vibrator on the surface to keep them moving like the old football games. now set that trough out in the sun like the solar ovens the boyscouts made, but a little fancier being covered in greenhouse glass. the temperature would easily get to 400. freznel lense maybe to 450. a cheap experiment to run, where if it works all you'd need to do is pour coffee in the top and get your roast at the bottom when they finally made it there. coffee is always moving so no burning, maybe a little emergency solar cell that ran a few motors for a shake. id guess if you had a guy to weld you could make up a prototype in a day. if i lived somewhere like texas or nevada i'd do it myself. cheers!

For my graduation I recently designed a compact solar coffee roaster and water boiler using vacuum tubes originally designed for rooftop water heaters. Instead of converting sunlight into electricity and then back into heat I used solar heat directly. I was only able to produce very small batches and the roasting process was definitely not as controlled as usual but none the less quite a fun experiment. If you Google "living with the sun coffee" you can read more about it :).

“Little Green Beans”. :)

As an electrical engineering graduate, just wanna note that kW is a measure of power which in and of itself is a rate of energy delivery. So kWh is the actual measure of energy. The Bellwether being rated to 9kW means that it needs 9kWh of energy to run for an hour. If you multiply it by 3600 to get the output in the SI unit for energy, you get 3.24 MegaJoules. Also all of this doesn't account for energy lost in the conversion to battery and then from the battery to the actual roaster.

Here in Belgium we have a company already roasting 100% solar called Ray & Jules. They created their own solar roaster in 2019! ❤️

Great video, I think you just created a start-up truly, a chain of substainable coffee shops.

I'm learning one of the current constraints (beyond cost) in the US to adopt larger electric roasters like the 8kg Stronghold, are the requirements of 3 phase power. It also draws almost 35kW, meaning battery storage requires a huge array. I'm hopeful that as more large devices electrify, this will become easier to adopt.

Last year for fun, I roasted coffee on a cast iron pan, on a barbecue grill at -17C. All in all, it was far from the best I’ve ever had, but it certainly wasn’t the worse. Beans came out somewhere between medium and dark roast. I had to keep the lid 80% closed to keep the cold from cooling the bbq. I also continuously shook the pan to keep the beans moving… for 45 minutes! 🤪

One of the funny things about natural gas is that if your electric company is using natural gas, it is vastly more effecient (i.e. uses much less gas overall) and much cheapers to just pump the gas on site for heating applications than it is to use the gas to generate electricity, transfer the electricity, and use the electricity to make heat. Very recently, however, heat pumps have started to become effecient enough to not make that true anymore

​@@BillyBraga That's only with air conditioners (Americans call them heat pumps, because they also have ACs that can't produce heat, which is not a thing in Europe). Say a power plant has a 50% efficiency (that's quite high) and you burn 1kg of LPG. Just burning 1kg produces around 7kWh of heat energy. So, the power plant can produce 3.5kWh of electricity and the other 3.5kWh are just released as heat (that can either be dumped in the air, or used to directly heat homes, the latter of which is common in Europe). Transporting that electricity is not 100% efficient either, so you may get 3kWh of electricity. Plug that into a space heater and you get 3kWh of heat energy in your room. A gas heater will give you the whole 7kWh of heat by burning the gas locally. There are some transport losses and losses from the gas heater itself, but those are negligible compared to those of the power plant. An AC would avoid that by "moving" and "concentrating" heat from outside, which is a lot more efficient. An AC might be able to "move" 5kWh of heat from outside and only use 1kWh to do so. That would mean that you would get 15kWh of heat from an AC with the 3kWh mentioned above - so twice as much as burning the gas! A bit of napkin math, but that's the basic idea

James, this is way too wholesome, please buy a coffee flavoured soda and present us with a glorious rant again ;) lol.

I rate the physics about a B or B+. It was either entirely correct or mostly correct, but often enough James mixed up energy and power, kW and kWh, that I can't quite give top marks. Still, good effort overall, certainly well above the youtube average. Energy is, in many ways, the fundamental unit of the universe. All stuff that happens, loosely speaking, happens because some energy is available somehow by which to achieve the stuff that happens. Power, on the other hand, is energy-per-time. One ought not confuse energy, as a fundamental conserved quantity of the universe, with its rate, energy-per-time, aka power. A watt, and kilowatt, is a unit of power. It is energy-per-time. kilowatt-hours, naturally, is thus a unit of energy. (Physicists prefer to speak in joules, which is a watt-second, not kilowatt-hours, but electricity providers the world over use kWh.) A battery, which stores energy, should be spoken about in terms of kilowatt-hours, almost never plain kilowatts. Conversely, the power consumed by a machine as it operates is power, energy-per-time, kilowatts, not kilowatt-hours. So if a roaster consumes 3 kW of power while it operates, then running it for 1 hour consumes 3 kilowatt-hours. Running it for 5 hours consumes 15 kilowatt-hours. But when speaking of the machine in the abstract, the time of operation is left unspecified, so we must talk of power, energy-per-time, not energy. For reference for other household items, microwaves or high end gaming/workstation desktop computers consume around 1 kilowatt of power, when they're running at full tilt. Most modern LED lightbulbs consume around 10 watts, altho older incandescent bulbs were closer to 60-120 watts. (LEDs lights are fantastic for reducing household power consumption.) A modern smartphone tends to consume around 15 watts in most cases, altho if you're really stressing its chip with, say, a high definition live video call + GPS, it might draw up to around 30 watts of power. A router uses around 5 watts, and I think the actual wireless signal is broadcast at about 1 watt of power, but don't quote me on that. So a 3 kilowatt espresso machine is considerably more power hungry than even a fancy modern desktop, and much hungrier than lights or phones or routers. A 9 kilowatt roaster would be by far the biggest chugger in a household, tho it is of course a low end industrial roaster, not remotely any sort of consumer machine lol. For other reference, most modern solar panels tend to produce about 1 kilowatt per square meter of electricty from sunlight, altho the total power of sunlight hitting the ground anywhere on earth tends to be closer to 5 to 10 kilowatts per square meter (depending on time of day, season of the year, atmospheric content, etc etc). Consumer-grade car engines produce around 100-200 horsepower, which is around 75-150 kilowatts. This is why electrifying transportation is so damned difficult, because just moving a standard average car around takes as much power as 20-40ish residential households (depending), or around 10 of these electric roasters. An American diesel freight locomotive puts out around 4400hp ~ 3300 kilowatts, or around 400 of these electric roasters. A modern electric passenger high speed locomotive puts out around 8000 kilowatts to the wheels, which is like 900 or so of these roasters.

I got 2/3rds through this video before I started asking myself, _why is James roasting coffee via a solar battery in the middle of a rather American-looking desert?_ He just makes it seem so natural!
