Because it’s hydrogen, the only emissions will be water vapor. Still, outside experts caution that the environmental impact of such water-vapor “contrails” remains unknown in a real-world or large-scale scenario.The International Energy Agency says air travel is responsible for about 2% of global emissions of carbon dioxide.

Hydrogen has been used in flights for decades but as a gas, not a liquid. Use of liquid hydrogen will take time to scale up. Fossil fuels, which are cheaper and more efficient, still produce most hydrogen today.Many governments want to, but for now, the world can’t make enough clean electricity for power needs on land, let alone to generate enough for wide-scale use by planes in the air.

In the last year, the team has built the cockpit shell, started building the wing spar, and finalized interior components. They include swivel seats, a bunk and a stationary bicycle-like workout system to promote blood circulation for the co-pilots who will be cramped in a small cockpit in low-oxygen conditions over the nine days.

The hardest parts await.Nothing was said about the

who raced to develop the country’s infrastructure for the World Cup tournament three years ago, or Qatar’s, which makes possible such elaborate central planning.

The Republican president’s admiration reflects an aesthetic and political vision at odds with American tradition. After declaring independence from the British monarchy, the Founding Fathers wanted to eschew anything that suggested royalty. Even as the United States emerged as the global superpower, the country and its leaders emphasized a facade of humility.But that’s never been Trump’s style. The billionaire’s New York City penthouse is embellished with gold and marble, and parts of his Mar-a-Lago club in Florida are modeled after France’s Palace of Versailles.
