Fly or not fly? That’s the question that people think more likely to grow. Sometimes taking the plane as a can choose, maybe when time is tight or when a lover is living far away.
I think we can fly as part of a sustainable future – but if we put some mistakes to rest the effects of global warming.
The first myth is called Durable fuel (SAF) can solve the problem. It is a complete misnomer, as the SAf turns away from lasting at all.
Here is why. There are three main types of saf. The first is fuel from waste products, especially cooking oil. The problem is, the whole waste of oil cooking can be sufficient in power 2 to 3 percent of trips. The second is synthetic safety, made from raw materials such as carbon dioxide with energy from modified sources. The process involved is ineffective (at least 2 kilowatt-time power input per 1 kwh of gasoline made) that it is a self-defeating self-use of our limited power. The third type of SAF is made from plants, so many farms are needed. The harmful pressure it places in our food system and nature is a big problem. The hard reality is that lasting fuel fuel is actually not a “game coser”.
The next piece of good thinking I always know is that we can disarvalize aviation by electrification or by using hydrogen as a fuel. Electrification can be practical only for dry-haul flights because the weight of batteries interprets it unnecessary for long operation. Hydrogen is happy because it takes a lot of space, even if pressured 700 times atmospheric pressure. This means it should be kept in large, pressurized cylinders, to make it bad compared to liquid fuel.
The good news is that I also see some clear opportunities without getting enough attention.
The closest thing we have had a bad silver bullet to make the aviation greener flown under the radar so far. Contracts – Those HighClouds are like streaks left with airline fumes – amount over 60 percent of climate change effect, as, 20 years.
They do this by reflecting the heat released on the surface of the ground backward, which acts like a blanket. But the overall impact of a Contractil is complex. They don’t just trapped in the ground hot, but on a hot day they could have an impact on repair by reflecting future sunshine. It happened during the day, and they cooled the most if contractils were above a more cloudy face, like the sea. The more frequent, the effect of warming most of the night when it happens hot, dark surfaces.
It is possible to manage contracils by creating small tweaks of flight paths: taking a plane above, below or around or in a particular pocket of time they can form. If the flight of a bright ocean, it can still be an advantage to deliberately doing it. Small tweaks of 1.7 percent of all flight paths can have an effect on cutting effect on contraint heating at around 60 percent. All that is needed is some real-time modeling built in calculating the way to fly, and no more flexible than ever applying to prevent storms and other airplanes.
This is a cheap cheap solution, one that only requires the aviation industry to get it. Once contracil management is in place, it may still have a paper for the SAF, because it can be burned cleaner and can be used to lighten the resistances of offensive trips.
Does this mean we can all relax about the flight climate effect? Sadly absent. But it helps us keep flying if we have a good reason to do it.
