eventually we would hope to get there, but, we are trying to have an edge somewhere that isn't the literal most refined and large capex part of the market first. if we can have a 10x edge

oxygen works and might be worth it for a stationary application like a powerplant for an AI data center. but NOx breaks down exothermically. so our approach if you hold the flame at >1300 C for less than a second or so you can destroy mo

fuel cells have trouble being cheap, lightweight, high efficiency, and long lasting, all at the same time. I think this could have better scaling on all those dimensions, plus could use natural gas or propane or other fuels for when you don

we don't see any degradation in sapphire tubes, though quartz, which is more convenient to work with because it almost completely resists thermoshock, does degrade slowly. there is a layer of salt on the tube which becomes transparent

that's correct. the mass of the power related systems are a moving target based on what we're developing. but we are aiming for a medium term target of > 1 kW / kg for e.g. DC power to a drone or a hybrid drone power syste

we're not aiming to break records with the absolute heat exchanger efficiency, which can get into the high 90s (%) if you're willing to devote a lot of space and mass, but we are innovating in the heat exchanger area. to capture m

you need at least valves/regulators, but for self pressurized fuels like propane, butane, or even natural gas (CNG or LNG) you can probably get away with only that, and fans for air intake and cell cooling.

we're bootstrapping off the multijunction production while using just a single junction that matches the sodium D light well

indeed yes; the sodium is added as sodium chloride. in molten form, it wicks along sapphire and alumina surfaces, similar to a candle. it reforms into sodium chloride as the temperature drops below its boiling point -- 1400 C. we're ex

maybe so. i don't know about attritable for the first applications though. may long range or duration oversight. a large % of the cost is these specialty cells which have not been scaled up to mass production. in the denominator is the

it can work purely from heat, however our process requires high temperature heat for power density.

hey! this is the inventor, danielle fong. thanks to curl-up who posted this, whoever you are. since it came up, "wire-to-wire" efficiency is what I intended to coin a synonym for electrical to electrical efficiency, with hydrogen
