A pair of new technologies could reduce the cost of capturing carbon dioxide from coal plants and help utilities comply with existing and proposed environmental regulations, including requirements to reduce greenhouse-gas emissions. Both involve burning coal in the presence of pure oxygen rather than air, which is mostly nitrogen. The basic idea of burning fossil fuels in pure oxygen is not new. The drawback is that it is more expensive than conventional coal plant technology, because it requires additional equipment to separate oxygen and nitrogen. The new technologies attempt to offset at least some of this cost by improving efficiency and reducing capital costs in other areas of a coal plant.

When investigators try to discover what caused an airliner to crash, the first thing they hope to find are the flight data recorders, popularly known as “black boxes”. These devices, usually painted bright orange, record how the aircraft was flying and the last 30 minutes or so of conversation in the cockpit. The information extracted from them has helped to determine the cause of air crashes and to improve aviation safety. Similar recording systems are fitted to some trains, ships and lorries. Now a bill in America’s Congress seeks to make it compulsory for data recorders to be fitted to all cars by 2015.
The idea is that data captured by the recorders would give investigators and road-safety officials a better understanding of how certain crashes come about.
