In the air, the Airbus A320 passenger plane is one of the most fuel-efficient single-aisle aircraft that airlines can invest in. On the ground, however, Airbus found a way to make at least the Airbus A320 series plane even more fuel-efficient, but not using the main engines. Of course, the only way that Airbus can […]

We’ve covered airplane fuel economy before, and there are a number of approaches to improving it, including use of lighter materials, lighter hybrid control systems, and more efficient engines. We often think of airplane fuel economy in terms of how many miles each seat can go per gallon, referred to as seat-miles per gallon [sMPG]. […]

A new refrigerant developed by Honeywell and Dupont, HFO-1234yf, will be required by law to replace R-134a, but Volkswagen is rejecting this and developing its own carbon dioxide air conditioning system. The new refrigerant, HFO-1234yf, is supposed to reduce greenhouse gas emissions by something like 99.7%. In spite of a new law in the EU […]
