Na, we should get rid of that idea completely. If everyone used one time like UTC (other time zones are available) and just align your working hours etc to your location.

Then 14:00 is 14:00 everywhere, just that some are asleep then, others are awake!

That’s always been true of city warfare though. Tanks are not designed for that.

That requires lots of cropland though. Hydrogen can effectively be made by offshore wind farms etc.

It might work if we reduce standard fuel requirements for cars etc enough.

Electricity has been around that long too though, yet there are no serious electric passenger planes (with a decent range)

It has it’s flaws, but it may have a higher ceiling in terms of usefulness. They say they can make it work, which is more than I hear about electric planes for example.

We should be financially encouraging 0 carbon planes, without controlling how, then let the engineers work what tech to do it with.

What are the other 0 carbon flight options? They are all flawed.

We can engineer our way through flaws with enough effort though.

…then there should be regulatory actions to help make them viable

Wait, really?

So you need a visa to transit through the US?

You can hear to some level, the boats and actions in the vicinity of the cable. So it might provide evidence in case of a break.

It also lets you know if the cable is moving round on the seabed etc, this is useful as it can cause wear.

I seem to remember it being used to check the health of power cables too (they have fibre cables embedded within them)
