Where is the titanium in salt water ? the headline and the story don't make sense ?!

Sun, salt water could make fuel, scientists say.


Researchers from the University of New South Wales say harnessing the sun to create fuel from salt water could be a commercial reality more quickly if research was better funded.
The scientists are working to improve the ability of a commonly used white powder to absorb sunlight.
Dr Leigh Sheppard from the Centre for Materials Research in Energy Conservation says titanium dioxide could become a key part of a no-emission technology.
"We're promising to produce a fuel, hydrogen fuel which is very clean," Dr Sheppard said.
"When you combust it, it produces water, it doesn't produce carbon dioxide, which is a greenhouse gas.
"There's a lot of promise, we just need sunlight and salt water, and we have a sustainable clean fuel."
Dr Shepherd says it is hard to get commercial investment to match the Federal Government's low emission technology funding when the technology is a decade away, but it could become available sooner if there was more research money.
