Navy Demonstrates Fuel From Seawater Production

A team of US Navy research scientists has developed a method to produce liquid fuel from seawater, using CO2 and hydrogen extracted from the ocean and then processed with a metal catalyst to produce liquid fuel. As a demonstration of the concept, an unmodified scale airplane has been flown with the seawater fuel.

The concentration of CO2 is about 140 times higher in seawater than it is in the atmosphere. Carbon dioxide and hydrogen are the two feedstocks needed to make hydrocarbons. The process relies on "an iron-based catalyst [which] has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production in favor of longer-chain unsaturated hydrocarbons (olefins)." The process is claimed to be the first technology of this type with the potential for commercial implementation.

"The predicted cost of jet fuel using these technologies is in the range of cialis from india tadalafil $3-$6 per gallon, and with sufficient funding and partnerships, this approach could be commercially viable within the next seven to generic levitra ten years."

Oh how wonderful

Now we can look forward to our oceans being polluted by olefins. There is also the risk that the olefins are further processed and used in fast food ingredients.

Dangerous technology like this should be outlawed before commercial interests become too entrenched in it.

This is wonderful news for it can reduce CO2 in the water and atmosphere significantly. Keep up this outstanding work.

We have been pray for this many year. Seawater is solution to all problems. It is possible to convert sea water into many different products.

Some things: Fuel for submarine, fuel for motor bike, fuel for public bus, fuel for the street kitchen making the nice curry, fuel for sewage pumps.

After convert to fuel can then convert into elaborate item like Lego brick, syrop and automotive use.
