I am not sure I understand your concern DrQuine. Are you afraid this tiny cell would explode mid-air? I think a bottle of high proof alcohol is more likely to create more damage, and that is even licensed for internal; consumption!...Kris
Any consumer product will need to be certified safe for travel (and ideally operation) in commercial aircraft. Will that be possible for a device operating at such a high temperature? What would happen if there were a car crash while such a device were in use by a passenger? If the safety issues can be resolved, certainly a long life power source will be much appreciated by our "plugged in" world.
I am still wondering how it operates at 510C? I assume that it must either be: heated or generate the heating from the fuel. Does this lower the achieved efficiency? And further, how does this device work in real life,510C is quite hot..
The missing piece here is that fuel cells need to be fed fuel to operate. I think that we are all curious as to what fuel these would consume and mechanically how it would be fed to chip-type fuel cells. Does anyone know?
What is the life of such a battery? If such battery has to replace a Lithium battery then the expected life should be around 5 years. This concept is very good for batteries used in medical implants like pace makers. Are these batteries explosion proof and safe to use in medical devices?
What does it mean with power rating at high temperature? Does it mean the battery can harvest heat energy into electricity? But what will the source for 510 degrees C? It would be useful if anyone can explain how this fuel cell works.
"achieving a power density of 155 milliwatts per square centimeter (at 510 degrees Celsius)" temperature a bit too high probably. Unless they can build proper heat dissipation mechanisms into the battery itself. Anyone know whats the power density for typical Li-Po battery used in cell phones etc? quick google search shows numbers in wide range from 0.5-75 mW/Cm^2!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
