Frustrations with BP's inability to contain the oil spill in the Gulf Of Mexico has everyone from independent experts to Hollywood celebrities offering potential solutions.

James Cameron, both Hollywood heavyweight and underwater expert, was among 28 scientists, and government and private-sector experts, who met last week to discuss solutions for the environmental calamity.

The group has filed a report to the government which has not yet been made public.

Editing the report was highly-respected Canadian ocean scientist Joe MacInnis, who has logged more than 5,000 hours undersea on 800 dives. He has worked extensively with Cameron, writing two books on the director's deep-sea expeditions.

He told Canada AM that BP's team is made up of "oil guys" and not enough underwater scientists have been involved.

"Let's get some science people in, who think inside the ocean, and see if they can come up with some kind of solution," he said of the idea behind the group's meeting.

However, MacInnis said the group came away with a higher regard for BP than they went in with.

While he could not comment on what was in the group's report, as it is before government agencies at the time being, he said there are "valid ideas" in it.

"It gives me some cause for optimism," he said.

Since the oil spill occurred BP has received more than 35,000 submissions on how to clean up the millions of litres of oil in the Gulf.

About 800 submissions have been forwarded to teams of engineers and scientists to test their validity, according to the company.

Bill Nye, the host of Disney's child science program "Bill Nye the Science Guy," said he himself has received about 1,000 ideas on his webpage.

However, he told Canada AM that many people do not fully comprehend the difficulty the atmospheric pressure at 1,500 metres under the surface has on capping the oil leak.

Additionally, he said while much of the focus of the cleanup operation is on the oil that has reached the surface, he speculated up to 4,000 barrels of oil a day are being trapped between the ocean floor and the surface.

While a containment cap has allowed BP to capture about 11,000 barrels a day leaking from the oil well. Government experts has estimated the well is leaking anywhere from 12,000 to 19,000 barrels of oil a day.
