Now, they get to turn their engines off and use electrical power. Sounds good, right? But where is the electrical power being generated? Some plant off in nevada or something. Now, instead of LA getting polluted, nevada is getting polluted.
Yeah, I see what you mean. That's the problem with living in a closed system. There isn't really an 'anywhere' to send anything to since all there is - is 'here.'
You are both right, however it seems easier (and definitely cheaper) to me if the amount of polluting entries (into the eco-system) is reduced and focus the the efforts of the collective brain trust into "fixing (only) that kind of pollution".
Besides that it would seem profitable as energy companies would invest in a more efficient grid. 220 Volt for the consumer, 300 kiloVolt for (inter)national distribution, like in (western) Europe. That way not that much of renewable energy is wasted and less natural resources are needed for the current national/regional energy requirements. An added bonus is that the brain trust will have more time to create a efficient network for hydrogen distribution.
Recently I found out that there is a new material (graphene) that seems to be the ideal candidate for hydrogen tanks. Besides being a better conductor than silicium, it is also extremely strong (especially when it comes in contact with hydrogen). Articles 1
