If you follow the stories about this burning seawater (or the cancer cure variant) demo, note the reporter's name.
Or in many cases, evaporative cooling from cooling towers.TVP45 said:Dr. Roy, the materials scientist from Penn State, has stated that, despite appearances, the water is not burning. Philip Ball of Nature puts it a little more plainly, "Water is not a fuel."
You can always check the tailpipe of your car and note that water comes out as a product of burning. Or visit any power plant and note the clouds (water vapor) formed by burning.

You and I know that, and most PFers would understand, but I was thinking of the public at large. It's not just any power plant, but one's the burn fossil fuel. Some nuclear plants use cooling towers, and they put out a lot of water vapor. Some fossil plants use cooling towers, and they put out a lot more water vapor than the flue gas. Some local power plants put out brown flue gas, and I've seen brown clouds drifting east from horizon to horizon.TVP45 said:Yes, you do see clouds over the coolers, but I was referring to the flue gases.

russ_watters said:It all depends on the plant. Coal plants produce very little water vapor - gas turbine plants produce twice as much water as carbon dioxide.

Radiowaves are a form of electromagnetic radiation that can be used to heat objects. When radiowaves are directed towards saltwater, the water molecules absorb the energy and begin to vibrate, causing an increase in temperature. This increase in temperature can then be used to generate electricity through various methods, such as steam turbines or thermoelectric generators.
Yes, using radiowaves to heat saltwater is considered a renewable energy source. The energy from radiowaves is constantly being replenished by the sun, making it a sustainable option for generating electricity.
One potential benefit is that saltwater is readily available and covers a large portion of the Earth's surface, making it a widely accessible resource. Additionally, using radiowaves to heat saltwater does not produce any greenhouse gas emissions, making it a clean and environmentally friendly energy source.
One drawback is that the technology for harnessing radiowaves and converting them into usable energy is still in its early stages and may not be as efficient as other renewable energy sources. Additionally, the equipment and infrastructure needed for this method may be costly to implement.
Compared to other renewable energy sources such as solar and wind, using radiowaves to heat saltwater may have a more consistent and predictable energy output. However, it may not be as widely available and may require more advanced technology and infrastructure. It is important to consider all factors when evaluating the viability of using radiowaves to heat saltwater as an energy source.
