94 % of electricity... Then 77 %... Then 94 % again. Without ever saying how much solar power was actually installed to begin with.

77 % is 91 % more than than 7.7 %. How the fuck are other systems supposed to be THAT inefficient? And now, just by not having a battery and a faster system response (that the others do not need to begin with) they get to 77 %?

Is this bullshit to get money?

The system harnessed, on average, over 94% of the electrical energy generated from the system’s solar panels to produce up to 5,000 liters of water per day

On average, the system directly used 77% of the available electrical energy produced by the solar panels, which the team estimated was 91% more than traditional solar powered electro-dialysis systems.

Throughout the trial, the prototype operated under a wide range of solar conditions, harnessing over 94 percent of the solar panel’s electrical energy, on average, to directly power desalination

Yeah, I agree that the lack of real numbers is incredibly annoying. However, 5,000 liters of water per day on solar power is pretty awesome. That could be life changing in certain areas. It might be too expensive for it to be installed in those placed, though.

It is only awesome if the same power could not have made 10x with the conventional systems. But who knows without absolute numbers?
