Giant Ants in Ancient North America

Big insects once roamed the US. They were very big. Ants were the size of small birds 50 million years ago. They are thought to have crossed the arctic land bridge that once existed between Europe and the US. The Green River site in Wyoming has given up many new finds in the past.

Bruce Archibald of Simon Fraser University in British Columbia noted that the fossil was similar to one found in Germany. Only the queen of the Dorylus wilverthi species of ant living today reaches this size. Fittingly, the new ant has been named Titanomyrma lubei. Louis Lube found the specimen. While this ant is big for North America, big ants probably lived in other parts of the world because large fossils of other creatures have been found there.

Large ants only live a tropical climate in the present so North America was tropical millions of years ago. It is a mystery how they crossed the temperate Arctic region then. For brief periods this area became quite warm, up to 8 degrees Celsius, though not tropical. Bursts of carbon dioxide into the atmosphere from sediment was the culprit. With two sources for ancient giant ants now known it may be possible to identify where they originated.

Power Generation Via Hydrogen Is Not Taking Off

It is amazing how many will see something new, then run with it to the extreme saying this will change the world. This is true for virtually all non-fossil energy producing systems, but all of them have drawbacks and none have revolutionized the power sector. The two major problems have been high cost and inconstant energy production during the 24 hour period.

Scientists have worked on hydrogen systems for decades and success seems very distant. It is not being accepted for widespread use. Actually, hydrogen is a "byproduct" of energy production. When electricity is generated by any method the excess not used at a point in time is passed through water. It splits in oxygen and hydrogen via electrolysis with the fuel being stored to be used in the future. When hydrogen is recombined with oxygen, electricity is generate. Heat from the process can also be used directly for heating purposes.

As with other environmentally friendly electricity producing methods time will tell if hydrogen is accepted for general use. Perhaps hydrogen can be made in significant quantities from solar and wind generation. It could potentially make for a hybrid system producing electricity 24 hours a day. Until now, governments have been the main source of funding for hydrogen experiments. Apparently, the private sector sees little future in it. For non-fossil energy systems to flourish it is necessary for the community to work together. Unfortunately, individualism is the norm. Perhaps this is why there is very little progress.

New Finds of Early Humans Do Not Change the Basic Theory

Darwin got it right. Well actually he may not have. Fossils of early humans do not alter basic scientific thought in relation to evolution, Finds do not show a linear development toward advanced Man. Evolution though does tend to predict what new discoveries show. Claims that a particular fossil find is a breakthrough are just not true.

New dinosaur fossils, however, tend to be groundbreaking with regular identification of new type of dinosaurs. Indeed, they seem to have roamed on every continent. The book on dinosaur evolution has not yet been written. Time will tell how clear an understanding of it we can get.

New research teams need to be formed to go to all parts of the world and seek answers to evolution of mammals and reptiles, if indeed dinosaurs were reptiles. Some specialists today even question this view.

New Solar Power Station in Western Australia

Australia goes its own way in lower carbon power generation by opening a solar-diesel power station, the world's first, in Western Australia. Solar panels track the sun during the day. The station is built in a location that holds the record for the most days of maximum temperature. Use of the solar panels will lessen greenhouse gas emissions by 1119 tonnes a year.

the local Aboriginal community if fully supportive of the power plant in the Pilbara. Aboriginals named it Pippunyah, the name of the river nearby. Funding came from the Federal Government in its renewable remote power generation program via the Office of Energy in Western Australia.

It is unfortunate that solar power generation had to be combined with fossil fuel generation. Even getting natural gas there would have been better than diesel. It seems there is no perfect solution to the pollution problem. New systems only seem to meet requirements half way.
