Tech energy solutions 2024 -wind on the China water solar farm

 It’s the first time in China


The project sits 8 km (5 miles) off the coast and spans an impressive 1,223 hectares (3,023 acres). It uses 2,934 solar platforms that rest on large-scale offshore steel truss foundations, each platform measuring 60m (197 feet) by 35m (115 feet).

It’s the first time in China that a 66-kilovolt offshore cable paired with an onshore cable has been used for high-capacity, long-distance electricity transmission in the solar sector.

Once completed, this offshore solar farm is expected to generate 1.78 billion kilowatt-hours of electricity annually – enough to power around 2.67 million urban homes. It could also help save Carbon emissions

Benefits include


1) Less NIMBYism

2) Shades water for animals that prefer cooler water

3) Can be used in tandem with fish farms

4) Due to water having a higher albedo than land, there is more irradiance to pick up if the panels are bifacial, meaning higher panel efficiency

5) Cooling effects of water, also leading to higher panel efficiency

Can lighter than air vehicles (dirigibles) be the solution

Airships promise the speed of air freight with dramatically lower costs and direct door-to-door delivery. Picture one hovering above a factory. It lowers a winch to collect cargo, then floats silently across the ocean to deliver goods straight to their destination. No ports, no truck transfers, no delays. No unionized longshoremen.


Airships will also be able to go anywhere. Remote mining sites that currently depend on endless truck convoys could receive a week's worth of supplies in a single airship delivery. A family moving overseas could ship their belongings in days instead of months, at a fraction of today's costs. I could’ve used this. When planning my move to Abu Dhabi, movers quoted us $2,500 and a 22-week delivery time just to ship three boxes of kids’ toys.
Great facts about the cargo option for developers
