BP Oil Spill Containment Plan Flawed

Of course ice formed in the dome. The flow was restricted. The outlet is too small. They need a large diameter pipe. It should not be sealed at the bottom. That way the water can settle out. The Remote Operated Vehicles (ROV) can maintain its position until it can be anchored. The right design is more like a chimney. It can withstand changes in pressure. 12 inch pipe is readily available. That is a good starting point. I've emailed them. Please if you are with the press or government make BP realize this.
