Just because it’s not forbidden to post US politics somewhere does not mean you have to flood the place with it.

  • You could get a few stray drones exploding over the US mainland but do you think it would stop them from invading?

    Cuba can’t produce any significant amount of drones without imports. Being an island in the US backyard they can be blockaded with ease. Iran can still import their stuff over land.

    It’s relatively easy to bomb every launch site on a tiny island compared to Iran.

    It’s also easier to cover every path a drone could take from Cuba and still reach anything of value. You have tons on well supplied air bases that can use relatively cheap munitions launched from fighters instead of using dwindling supplies of patriot missiles.





  • Unless they use salt water they draw from the same supply of groundwater or surface water as drinking water.

    Drinking water is usually surface water or groundwater pumped from a lake/river or a drilled hole in the ground passed through a filter, an UV light to kill bacteria, and possibly some chemicals added to get the correct pH.

    The limiting factor for how much drinking water you can make is how much you can pump out of the ground/lake before it dries up.








  • How much does it cost to transport x kWh of electricity from outside of town into town?

    How much does it cost to build an elevated platform, lift the panel up there, rent a lift once in a while to enable routine maintenence?

    The reasons you don’t see this done is not because noone thought about it, it’s because it does not make economical sense (yet).


  • They only generate value when there are enough cars parked that need charging. How do you make sure that utilization is high?

    Solar panels are expensive buy and install. They are good when they are used to their full potential. But installing them anywhere just cause it’s a flat surface is not a good idea.
