How does a raft work?

The whole system takes the form of a raft, which is loaded with flat-plate collectors, thermoelectric modules, electrolysers and storage tanks for hydrogen and oxygen gases. Two kinds of inexhaustible resources, solar energy and sea water, are fully utilized in this method.

What is a raft based PV system?

Qi-energy and Candock have developed a raft-based system for utility-scale floating PV plants, based on special high-density polyethylene “dock cubes” supporting a nonmetallic frame.

What is a HEC raft?

The HEC is a 38-meter-long, 12 meter in height and 8 meter in width floating raft that maximizes energy efficiency through its hybrid design. Featuring six vertical wind turbines generate 300 kW and solar panels producing between 50 to 80 kW. The system is anchored by its ability to harness wave power with a total output of around 1 megawatt (MW).

What is a raft forming system?

Another type of raft-forming system consists of gel-forming solution (e.g., sodium alginate) containing effervescent agents that form a gel on contact with the gastric fluid. This solution generates a gel upon swelling with entrapped CO 2 and floats on the gastric contents forming a “raft.” Antacids are delivered feasibly using these raft systems.

What is a modular raft & how does it work?

The modular design allows for energy generation even during lower wave heights, providing continuous power output in various sea conditions. On top of the wave-energy platform, the raft is equipped with wind turbines designed to harness offshore wind. This makes it being stronger and more consistent than onshore wind.

Why should you use a raft?

“A rafted solution has much more flexibility in terms of buoyancy and can be designed to cater for much higher foot traffic associated with regular cleaning in certain regions.” The cubes are also placed much higher in the water, he said. This ensures that cables, combiners and inverters are out of harm’s way.
