Over past four years, new vehicles became 14% more fuel-efficient in U.S.A.

Fueling 36547

Another step ahead.

After what seemed like an eternity of mostly stagnation, average fuel economy for new vehicles has been going up in the United States. Researchers at the University of Michigan have conducted a study showing that for current model year vehicles, fuel economy is 14% higher than just four years ago, which might not sound like much, but it’s much better than what we’ve got in the recent past.

The study concludes that average fuel economy…

Wave rotor motor

Piston engines are big, heavy, dirty, complicated, and expensive pieces of machinery that have been around for a century. It’s about time for something better, and one option could be wave disk engines, which are small, light, clean, simple, and cheap pieces of machinery that aren’t around yet. But they’re close.

Featured invention at the DaVinci Inventor Showcase 2010

HammerWings are an innovative new technology developed in Denver, Colorado in 2009, that shape the airflow around a vehicle to make the vehicle more aerodynamic. The tractor-trailors, trucks, vans, SUVs, and minivans that are using HammerWings currently experience a 2%–14% improvement in fuel economy (depending on vehicle, load, driver and road conditions).

Airbus “fantasy plane”

As soon as 2030, we might be flying in a new, more efficient aircraft with long, curled wings, a U-shaped tail, and a lightweight body — if manufacturer Airbus develops the “fantasy plane” it unveiled today at the Farnborough Airshow in the UK. The concept aircraft is more fuel efficient, boasts advanced interior systems, and, best of all, it’s quieter.
