Our cruise from Manhattan to Toronto continues on the Viking Octantis.  We are on the St. Laurence Seaway. Seaway, because there are locks on the western portion of the St. Lawrence River. River flows from the Great Lakes in a northeasterly direction from Lake Ontario into the North Atlantic Ocean, and is #2 to the Mississippi River in North America. Remember my saying that a drop of water takes about three months to travel the entire length of the Mississippi River to the Gulf of Mexico?  Similarly, this hypothetical drop takes 6 to 8 years to pass through Lake Ontario to the Atlantic Ocean.  Or, from the furthest Lake Superior extreme, more than 200 years. Among the highlights include: Is fresh until around the city of Quebec, and eventually is ocean salty near Tadoussac. Portions of the seaway have peak tides up to 20 feet twice daily.  You would thus think that tidal plants would be prominent, for studies estimate a potential of 1.5 gigawatts, or 1555 megawatts. ...

Energy Matters today from the American Energy Society's 19August2024 issue : Global warming remediation. Seems awfully expensive, but the largest Direct Air Capture and Storage of Carbon Dioxide, 36,000 tons of CO2/year, is the plant at Mammoth in Hellisheioi, Iceland. The biggest one in the U.S. was launched this month in Northern Oklahoma.  5.000 tons/year. Said to cost $200 per metric ton, about the highest of all the options. Carbon Capture and Storage (CCS)  can cost today as low as $50/ton. However, this "low" cost would still increase electricity cost by 5 cents/kilowatt-hour in a coal-fed powerplant. Implementation is increasing , but very slowly, because there is still no carbon tax. Industry is experimenting and will not move forward unless real decisions are made to combat global warming.   Cost prohibits any use at home, so applications range from heavy industry to natural gas processing to hydrogen production. CCS is especially necessary in synthetic fue...
