A community about hydrogen and its use as a way to fight climate change.
All posts must be about hydrogen, fuel cells, or a related topic.
Posters that only attack hydrogen will not be tolerated.
Is it me, or does an invisible flame burner sound obscenely dangerous for a home cooktop?
I was more thinking it sounded like a horrible appliance to cook on. You can't tell how big the flames are if it's invisible.
I guess you're right though, perhaps it may pose a safety hazard.
This seems like they are just trying to find a way to sell more hydrogen, instead of trying to solve a real-world problem, or create something of actual value.
Using hydrogen to cook without fuel cells seems ... like a step back on energy efficiency.
Also it those nozzles malfunction ...
That's how you get mentioned in the same breath as she mona lisa 
Doing a little bit of research via Google on this, it seems that the 300 homes are the total for the hydrogen heating project. They are receiving hydrogen boilers presumably for hot water and central heating. An unspecified number of these appear to also be being provided with these hydrogen hobs. Safety fears have already been raised about leakage and safety in use. During demonstrations, they've added sodium carbonate at the burners to give an orange flame, but this will not be implemented for deployment in this project. Instead, they will use a light on each burner to indicate whether it is lit.
If my understanding of the above is correct, I struggle to see how this hob could be safe in use. Gas leakage is a major safety issue in a domestic setting. There's no mention whether they've been able to add a scent to detect a gas leak. Not being able to see the flame directly in daylight is another major issue and I'm surprised that having a lamp to indicate that the burner is ignited is considered sufficient. Quite apart from reliability issues, how obvious can it be that it means 'this bit is hot'?
