There are important and vital reasons related to air vehicles. Friends of the Earth revealed that the flight to the emergence of the fastest source of greenhouse gases. The report was written in 2008 and tried to prove that the airlines will contribute 1.5 billion tons of carbon dioxide into the air until 2025.
Electric Aircraft's flying from dream to reality
With numbers like that, it is not surprising that the European Commission wanted to shift some costs of pollution such as returning to the airlines themselves. And with numbers like those, are very welcome to read the plans of the European Aeronautics Defence and Space Company (EADS, for short) to develop all-electric aircraft are expected to fly the skies in 20 years.
Here's how the idea-that EADS calls a "concept of upstream research, rather than short-term commercial approach"-will work. The VoltAir, such as aircraft for the time being dubbed, will be supported by a large lithium-ion batteries, with energy density of 1000 Wh / kg. (Extrapolating from recent advances in battery research and development, EADS think this goal is achieved in two decades.) Jumbo battery will then power the motor, which will encourage the counter-rotating propellers at the end of the tail. And as if some of the toys, after the plane has landed, the airline can only swap out the used battery with a pre-cost, cutting down the time spent during refueling. An animated concept, which was presented at the Paris Air Show recently, can be seen here.
Regulate matters of conscience aside, EADS think all-electric aircraft would also lend itself to increased experience in general aviation. The aircraft will be quieter, for one thing, either because the machine would be inherently less noisy and because they will be sequestered in the back of the plane. Imagine a novel form of EADS aircraft will also make for a wider cabin, which means less climbing over fellow passengers or squeeze awkwardly past them in the hallway.
EADS is not the first to envision an all-electric aircraft. The model-sized aircraft has flown for decades, in fact. In 2007, several scientists made a splash by suggesting all-electric aircraft powered by superconducting motors could be on horizon. And "power", of course, is not a panacea. While undoubtedly greener than what we have today-plane VoltAir will not emit any carbon dioxide or nitrogen oxides in-flight aircraft even electricity is guaranteed to be completely green. That a large battery to be charged somehow, after all, and if it's coal power plants that do charge, it will still greenhouse gas emissions are large enough to be involved.
Finally, the design raises all sorts of questions on the fail-safes and backups. Are there any additional power or an emergency of some sort? As a commenter on Inhabitat recently noted, here is an example where a dead battery would be something much more than a mere interruption.
