With respect to burning iron - they do state that the combustion process only gets 40% of the energy back as electricity, which is near perfect Carnot efficiency, but still a big loss.

You are correct that there are more efficient competitors. Using the iron to make a battery would have a lot less motion and labour (making it much cheaper), would be easily scalable from home-use to grid-capacity, and would be over 90% efficient.

"UK contact-tracing apps start to talk to each other"

My brain is slower than usual in the morning and I was imagining the apps chatting to each other on social media there for a while.

New Zealand's finally starting to do a proper test of its covid-card...

The test is only for a week so how well it works should be known in a couple of weeks, at a guess.
