The first video of the already famous 40 meter tank in Lisbon is here to see...enjoy.
I do not intend to criticise in any way this beautiful project that can be very useful to raise awareness about nature conservation... but it makes me think why they still call it Natural Aquarium.Assuming x10 flow for this tank that is 1600m3 per hour. My JBL consumes 23W doing 1500l/hr (1.5m3/hr). Thus roughly power needed is 23 x 1600/1,5 -> 23,000W and at electricity @ 15p/KWhr -> 23 * 0.15 * 24 * 365 -> £30,222 per year in electricity. Obviously bigger pumps will be more efficient and I expect they get cheaper electricity....
I have a 200W heater in 180l tank, they need 200 x 160,000/180 -> 170KW !!!!
