Erlingen, Germany: Solar-powered planes could offer a low-carbon air travel option, according to a new research report.
Air travel by plane is currently the most damaging to the planet. But using aircraft with lightweight batteries filled with a mixture of hydrogen and helium would produce one to five percent more emissions than conventional aircraft.
The only problem with using these airstrips is that it takes about two days and nights to travel from London to New York and three days and nights back if the winds are normal.

In a study published in the International Journal of Sustainable Energy, researchers say airships could be a more sustainable alternative to medium- and long-haul flights.
According to scientists, switching from jet fuel to hydrogen or electric power is currently not possible with the technology available in the future.
“If we rely on solar-powered aircraft, we can make air travel more environmentally friendly, relatively faster and more affordable,” said Professor Christoph Flom.
He said that according to the calculations of the researchers, solar airplanes can significantly reduce the cost of travel and the amount of carbon dioxide emitted in air travel.
