I’ll take ‘Violations of the Magnuson-Moss Warranty Act’.

Batteries are expensive, short lived, less efficient, and polluting. They’re better than fossil fuels, but if they can be avoided they should.

Solar also isn’t very practical in CBDs, so you end up generating excess power in more rural areas and transporting it into densely populated areas, like most other commodities.

Indeed, the US has a major lack of fixed-line competition and lack of regulation. Starlink doesn’t really help with that, at least in urban areas.

I’m not familiar with the wireless situation. You’re saying that there are significant coverage discrepancies to the point where many if not most consumers are choosing a carrier based on coverage, not pricing/plans? There’s always areas with unequal coverage but I didn’t think they were that common.

Here in NZ, the state funding for very rural 4G broadband (Rural Broadband Initiative 2 / RBI-2) went to the Rural Connectivity Group, setting up sites used and owned equally by all three providers, to reduce costs where capacity isn’t the constraint.

Starlink plugs the rural coverage gaps, but in urban areas it’s still more expensive than either conventional fixed-line connections or wireless (4G/5G) broadband. Even in rural areas, while it’s the best option, it’s rarely the cheapest, at least in the NZ market I’m familiar with.

It also doesn’t have the bandwidth per square kilometre/mile to serve urban areas well, and it’s probably never going to work in apartment buildings.

This is a funding/subsidisation issue, not so much a technical one. I imagine Starlink connections are eligible for the current subsidy, but in most cases it’s probably going to conventional DSL/cable/fibre/4G connections.

Aggregate bandwidth now rivals or slightly exceeds gigabit wired connections.

Where that aggregate bandwidth is shared amongst large numbers of users, bandwidth per user can suffer dramatically.

Low density areas may be fine, but cube farms are an issue especially when staff are doing data intensive or latency sensitive tasks.

If you’re giving employees docking stations for their laptops, running ethernet to those docking stations is a no-brainer.

Moving most of the traffic to wired connections frees up spectrum/bandwidth for situations that do need to be wireless.

Properly managed, groundwater can be sustainable.

The issue is that the energy required per litre of water is poor, even with high humidity. Other options, like long pipelines from other areas or desalination, start looking very appealing.

The issue is always energy density and round-trip efficiency, and I don’t see numbers for either of these. Remember that you do have to actually liquify the air first, and that takes power.
