The plane reduces the noise of the sonic boom — a loud bang caused by shockwaves created by an object moving faster than the speed of sound. “This noise has been the main limit, if not the only one, preventing the opening of lines other than transatlantic ones for the Concorde aircraft,” the patent says. The plane does that by being “near-vertical,” like a rocket, while ramping up to supersonic speed and its cruising altitude of 30,000 to 35,000 meters — 20 kilometers higher than conventional commercial aircraft.
From wind-energy to gas. It’s a great opportunity for the Dutch
The Netherlands had always a lot of gas in the North East but the gas is decreasing. Since a few years, renewable energy is growing fast with solar panels and wind parks. But storage of electricity remains a question.
ECN examined the role of power-to-gas in the Dutch energy system of the future.
Power-to-Gas (P2G) is a technique in which electrical energy is converted by electrolysis gas. A way to store renewable energy.
