Energy question of the week: Is it possible to fly on nothing but solar power?

In cruise ships, electrical propulsion units – powered by diesel engines – are now standard equipment. Every day, buses with electric motors powered by fuel cells ply the streets of Hamburg. Now the first aircraft powered solely by electric motors are taking off. However, in the quest to find exciting, original and climate-friendly propulsion, are solar cells powerful enough to get an aircraft off the ground? read more

Energy question of the week: How can electricity be generated from hydrogen?

Fuel cells are surely the most elegant way of converting energy-rich fuels into electricity without emitting any carbon dioxide or other exhaust gases if hydrogen is the type of fuel used. Back in 1838, the German-Swiss chemist Christian Friedrich Schönbein successfully generated an electrical voltage from hydrogen and oxygen for the first time, using two platinum wires to accomplish this feat. Since then, many different types of fuel cells have been developed to a commercially marketable standard. What underlying principle do they all have in common? read more
