IIRC, too much energy required to separate the oil and water.

If you inject a hotel into the jet stream you only need to fly up and down. Of course, in each hemisphere it's only one way.

Vodka from the air:

Amid the coronavirus pandemic, climate change still demands global attention, which is why a green movement is sweeping the wine and spirits world.

Did you know that synthetic bioluminescence from bacteria could make lighting in wineries more sustainable? Or that distillers can use solar power to create vodka out of thin air and water? These are among the surprising things I learned at a forum on wine and climate change at Vinexpo Paris in February, before social distancing became a way of life and air travel a memory
www.sciencemag.org/news: Ammonia—a renewable fuel made from sun, air, and water—could power the globe without carbon
Quote:
(That's where MacFarlane comes in.) For the past 4 years, he has been working on a fuel cell that can convert renewable electricity into a carbon-free fuel: ammonia. Fuel cells typically use the energy stored in chemical bonds to make electricity; MacFarlane's operates in reverse. In his third-floor laboratory, he shows off one of the devices, about the size of a hockey puck and clad in stainless steel. Two plastic tubes on its backside feed it nitrogen gas and water, and a power cord supplies electricity. Through a third tube on its front, it silently exhales gaseous ammonia, all without the heat, pressure, and carbon emissions normally needed to make the chemical. "This is breathing nitrogen in and breathing ammonia out," MacFarlane says, beaming like a proud father.

Quote:
Well before the oil price rout caused by the coronavirus pandemic, commentators and shareholders were calling on Big Oil to make step-out energy transition acquisitions.

Now, with economies in lockdown and corporates fighting to survive, the oil sector’s incremental move into new energy looks over-cautious.

As the value of their fossil fuel assets tumbles, the coronavirus lays bare these companies’ exposure to a world of massively smaller oil and gas demand, offering a glimpse of the EV revolution to come.
