As you say it's just a liquid, it doesn't 'work' at all, and it certainly doesn't power cars. The burning of gasoline, really the exploding of gasoline, is what powers internal combustion engines.

Gasoline is ignited with a spark, inside a container, where the only escape route for the explosion is the direction we need to apply force.

>the TVs in question don't appear to fold or come apart

No shit, but it would be helpful if you provided an example of the TV in question? Looks like their largest commercial screen of 97" is 'coming soon', it's just under 1.3M in height, I just measured a standard door@1.97M.

I'd guess they take the doors off or worst case, remove a window, like with a normal TV and whatever example you've seen LOOKS as though it's larger than the property's doorways, but in actual fact you're estimation of relative size is off.

International trade is complicated.

Say we have 3 countries;

Country A

• has companies that produce steel
• has a manufacturing base that consumes steel
• has trade agreements with country B, and country C on steel trade providing lower than normal tarrifs

Country B

• has companies that consume steel

Country C

• has companies that produce steel

It's possible that country A's steel producers can make easier, or even higher profits selling steel in bulk to country B than if they were to service their manufacturing base.

At the same time, their manufacturing base could get cheaper steel from country C if, for example, it costs them less to make it.

Companies in country B, can't trade with companies in country C at the same cheaper rate, because the countries don't have a trade agreement setting lower costs on the steel trade for whatever reason.
