Offtopic > The emissions from travel it took to report this story were 0kg CO2. The digital emissions from this story are an estimated 1.2g to 3.6g CO2 per page view. Isn't 1.2g per page view huge amount? I wonder if we can have api for this.

Well, you exceeded that in 5 minutes yourself by just existing.

Some envelope math. From https://www.eia.gov/tools/faqs/faq.php?id=74&t=11 , I get .99 pounds of CO2 per kWh. That converts to 449 grams. Splitting the difference between 1.2g and 3.6g, we get 2.4g. 2.4/449= 0.00534 or ~0.53% of 1 kWh consumed, or 5.3 watt-hours. Which does strike me as rather high.

This helps control evaporation losses as well, the water flow in canals is more predictable which helps. Also there is a great potential for floating solar especially behind existing hydro as the grid infrastructure almost exists.

I wonder how this would affect the climate, the rains especially.

There was a proposal to do this to the California aqueduct, but it turns out they don’t lose much water from evaporation and it would be cheaper to put them on land. https://green.blogs.nytimes.com/2011/04/20/could-the-califor...

CA aqueduct proposal was floating panels. Not suspended above the canal.
