Green tour boat coming to San Francisco in 2009

There is an article at the link below that says a solar ferry (pun intended) boat will be coming to San Francisco in 2009.

In two years, tourists will likely be traveling to Alcatraz on green energy.

Australia's Solar Sailor has come up with a way to make large solar panels that can also act like sails.

Put one or more of the sails on a boat and the boat gets converted into a hybrid. The boat still has a diesel engine, but it mostly gets around on wind or sun power.

A tour boat in Sydney Harbor has an array of eight small solar sails.

The San Francisco boat (pictured) will likely be able to go several knots on wind power alone.

The sail on the San Francisco boat will approximately be 15 meters high. The boat will only have one sail. The Sydney boat has eight shorter sales that can be sailed in unison or individually. Computer studies, however, convinced Dane that the best design involves only one or two sails.

Pacific Ocean whipped into froth near Sydney

Last August the Pacific Ocean foamed from a beach near Sydney, Australia.

Foam swallowed an entire beach and half the nearby buildings in a freak display of nature at Yamba in New South Wales.

It was as if someone had poured tons of coffee and milk into the ocean, then switched on a giant blender.

One minute a group of teenage surfers were waiting to catch a wave, the next they were swallowed up in a giant bubble bath. The foam was so light that they could puff it out of their hands and watch it float away.

It stretched for 30 miles out into the Pacific in a phenomenon not seen at the beach for more than three decades.

Scientists explain that the foam is created by impurities in the ocean, such as salts, chemicals, dead plants, decomposed fish and excretions from seaweed.

All are churned up together by powerful currents, which cause the water to form bubbles.
