PROLOGUE
The year is 2050, the first few flying cars are beginning to appear around the globe, only the super rich can afford them, but there is already a whole set of laws and regulation for those cars; maximum height, maximum speed, expensive licenses and so on.
Planes for International flights and travelling for vacation in foreign countries is a luxury no mundane civilian could afford as planes were banned all over the world around the year 2022, allegedly to prevent the spread of diseases.
For years, people stopped travelling, stayed home and most countries had to adjust and evolve in different ways, but mainly towards self sufficiency.
Countries that couldn't make it merged together, reshaping the world gradually and reducing its number of countries from about 200 to only 50 by 2040.
The number of language went from hundreds to 6, enforced and regulated so there would be no visible dialects in any of them; English, French, Mandarin, Russian, Spanish and Hindi.
The Vatican grew exponentially strong between 2020 and 2035, so much the entire world was on the verge of uniting under a single emblem, almost becoming one single country called; Earthopia. Prayers, restrictions, disciplines, good, evil... the usual brain washing and primal control. The Elite almost won.
But as the economy was stabilizing and poverty was turning into prosperity, the flock disbanded from God as fast as they had gone back to it in times of need.
The major cause of this downfall though, was the inventions of the Hydro-Gravicity Generator (HGG), a mechanical device using water and gravity to cause rapid movement of an object within a tube to produce electricity. Multiple prototypes were created in 2020 but it didn't spread much until the year 2035. Free and almost infinite electricity at a cost so cheap, everyone with a little brain and basic tools could make its own HGG to power their entire house and more.
The Vatican had been strongly opposed to the HGG, warning people against it, but free electricity spread faster than their lies and soon everyone had them and no one felt unsafe using it. The lies of the Vatican festered and people saw the truth behind all of it.
The HGG quickly became the new power source for everything, especially electric cars, providing an infinite range, but none was able to make one work in high altitude. The air density being reduced at higher altitude made the generator weak and unable to power large planes. Concerns about environment forced airlines to stop producing large planes using fossil fuel and for an HGG to produce enough energy to power a large plane, it had to be almost as large as the plane itself.
USA, Mexico and Canada although each successful in becoming self sufficient, merged into one single country, becoming one of three global superpower under the single banner of; Canamerico, although most simply call it The Amerix.
As of now, in the year 2050, everything is powered by HGGs, some as small as the typical AA Battery, used to power every small devices same as those batteries used to do, and some as large as a house, powering large buildings and skyscraper, but mainly, the typical HGG is the size of a couch and is enough to power a single house. Silent, causing no pollution at all and using components that won't break often, the HGG brought a level of independence people had never known before. Adding to the fact that most people had to grow their own food to survive and in large cities, people had to work together into creating gardens wherever they could, turning rooftops into Greenhouses, parks into gardens and even streets into gardens, the arrival of the flying cars marks the beginning of a new change to come.
People will be able to travel again, flying at about 200 km/h in a car that doesn't need to refuel since it's powered by an HGG.
Everything is not perfect, and people are still returning to old habits of consuming too much unnecessary things and as of now, besides those few little details; HGG, Greenhouses everywhere, and the newly flying Cars, life in 2050 has returned to be almost identical to how life was in the year 2019, before it all went to shit.
