"I know we'll be particularly interested to the answer to how beneficiary feedback has informed your current design."

We regularly iterate our design based on feedback from pilot users. For example, we changed the ash out removal system to make it both faster and easier, which lowered the O&M costs. We also added an optional CHP feature, when we learned just how important having heat could be to aid in the processing and drying of crops.  It's safe to say we are in an almost non-stop process of innovation and improvement, as we learn more about the places and ways in which these are intended to be used, and the wide range of potential fuels available for their use.

It would be great if you could tell us more about the feedback you've obtained from beneficiaries. Are you aiming to benefit small holder farmers? Farmers using agro-industrial processors? How will this idea benefit them? Specifically, can you tell us more about how you have tested this idea with your intended beneficiaries?

The goal is to make an energy device that benefits the whole agricultural value chain. We hear over and over that up to 40+% of crop yield can be wasted due to an inability to process it before spoiling, and that's often due to the lack of affordable power. So if we can get in there at the intersection of agriculture and industry, where there is machinery available to dry and process and preserve crops, and do it with various forms of agricultural waste, then that seems very worth doing.

We have tested this idea in a wide range of contexts. In Costa Rica, using coffee bean husks to run a dryer and roaster, in Uganda, to run a corn flour producer on corn cobs, etc.

What has become clear through this process over the last four years or so is the following:
1) Agricultural waste is much more affordable than diesel fuel. On average, diesel costs $.33USD per kilowatt hour of energy produced, compared to $.05USD for biomass.
2) Materials handling is more with biomass, but can be offset by lower cost of fuel
3) A more fuel flexible reactor design would enable wider use
4) The carbon benefits of using ag waste for energy, with biochar production and capture, hasn't been fully realized.

Who is using it?
Wide range of users around the world. Not all the same. Depends on where they are and what their energy needs. Most concise destription is as as drop in replacement for diesel power generation.

What training do they need?
Basic mechanical aptitude. We can generally train someone to use it appropriately in about 3-4 days.

Which businesses and communities are most relevant targets?
SMEs in communities with agricultural production.  So yes, the ag processors, but also all the other businesses that need power in the community (auto repair, small kiosk shops, small manufacturers that need high amperage power to run welders/saws/machinery).

The idea - at least as described here - seems to be focused on the invention and not the practical adoption.
We are happy to talk in great detail about either! Having been at market with four previous versions over six years, we have tens of thousands of data points from customers expressing interest, which gives us a clear image of how people would like to use it and with what fuel.
Consider: a PP20 Power Pallet, because of the high capacity factor, is equal to 80kW of solar power--yet it's only 4' on a side. And it works day or night, rain or shine. So all the places solar can't fit or won't work ( monsoon areas, etc ), this will.

I'm interested in market size and scale. I'd be curious to know what will help costs drop in 18 months. Is it material availability? Design improvements? Scale?
Primarily scaling. We are building these one at a time by hand in Berkeley, California, probably one of the most expensive places in the world to manufacture things. Just this week we are outsourcing a single component, and are seeing costs drop on that from $1400 to $300.  We are confident ( and able to back up ) our assertion that building at scale can cut the total unit cost in half.
Concurrent with that are improvements in power output, and reductions in O&M costs. A planned change to engine and generator components will boost power output by 20%, and changes in the last month have cut tar production by 60%, which dramatically lowers O&M costs.

This technology would be relevant where there is an abundance of feedstock and a need for high amperage. This would likely not be at the community level (unless there is an existing grid) but, more likely, at the agro-industrial level.
We don't see those as distinct--many communities have ag production surrounding a commercial center. Both need power.

Is there a possibility for co-gen of heat with this machinery? (Product drying, etc.)
Yes-optional CHP module produces 40kW in heat, along with power output.

I have questions about: <> Feedstock - what is the business for chipping, drying, storage, etc? <>Service - who can maintain, what is the lifecycle of machinery, which parts likely to break?
We can train operators, two year warranty, lifecycle 5 years +

<>Power - how is this power being distributed and stored? Does it get funneled into the grid or does the syngas get stored? Can the grid distribute appropriately? In the absence of a grid, how do stakeholders benefit?
It's made as needed, not stored--the fuel is the battery. Can be grid tied or work independently. Absent existing grid can tie directly to power using devices as needed. Very flexible.

That's all I can answer here I've used up all my allotted space!

Our vision is to replace the tens of millions of diesel generators in Africa and other parts of the developing world with biomass generators that can make power for less money, while sequestering carbon. Our innovation right now costs about double what a comparably sized diesel generator does, but we think we can cut the cost in half in 18 months. If we can, then we think we'll start to see the kind of reception Tesla got when they finally introduced an electric car that cost the same as a gasoline one.   The opportunity is enormous, and the potential impact on carbon, climate, and sustainable development is equally massive.
