2070-2079 Contents

2070

Fusion power is becoming widespread

Every leading country now has at least one fusion power plant either operational, or in the process of being constructed. Since they offer a clean, safe, abundant supply of power, these new reactors are revolutionising the world of energy production.

Expansion of Moon bases

Building on the success of the Helium-3 extraction programmes, a whole series of bases are appearing on the Moon. Other resources are now being mined including precious metals and minerals - resources which are becoming increasingly rare on Earth.

Perhaps more importantly, this is being combined with on-site processing and production, to build new structures and facilities around the original bases. Solar panels, tools and other equipment, for example, can be manufactured without needing to be delivered from Earth, whilst entire new buildings can be created with the help of robots and self-assembling nanofabricators. Paths can be carved out from the lunar regolith, with functional roads built on them using materials extracted nearby.

Meanwhile, small hydroponic farms - carefully controlled and maintained - are providing a continuous supply of food and water to the astronauts.

All of this is producing the critical mass needed for a thriving, self-sustaining presence on the Moon. A few decades from now, it will be open for civilian settlement.

Picotechnology is becoming practical

Technology on the scale of trillionths of a metre (10^-12) is becoming practical around this time.* This is orders of magnitude smaller than the nanotech of previous decades.* In the coming years, one significant development to come from this will be the Heisenberg compensators used in teleportation.

2074

The Green Wall of China is completed

A 73-year environmental project - to halt the advancing sands of the Gobi Desert - is finally completed this year.* Beijing and other cities along China's northeastern border are now protected from desertification by a 4,500 km barrier of newly planted trees.* This becomes the largest single ecological project of the century.

To build it, the government established a plan involving three approaches. Firstly, aerial seeding over vast swathes of land where the soil was less arid. Secondly, the paying of farmers to plant trees and shrubs in areas requiring greater attention. Thirdly, the construction of a huge fence along the perimeter.

Inside this gigantic new forest, sand-tolerant vegetation was arranged in optimised checkerboard patterns to create an artificial ecosystem that stabilised the dunes. A gravel platform held sand down and encouraged the formation of a soil crust. The government also funded research into genetically engineered plants, chemical dune stabilisation, grass strains bred in space, and even farming techniques that allowed rice to grow in sandy soil.

Prior to the Wall's erection, the Gobi had been advancing south at 3 km per year.

2075

London and other major cities are being flooded

Following a major flood - triggered by a combination of rising sea levels and extreme weather - the Thames Barrier in London has been replaced by a larger successor.*

The original barrier was raised a total of 62 times between 1983 and 2001. It was raised with increasing frequency as the decades went by. Towards the end of this century, its successor may have to be raised over 200 times every single year to cope with the combined impact of stronger storms and sea level rise.*

2076

Unmanned probes to Sedna

Sedna is a trans-Neptunian "dwarf planet", similar in size and composition to Pluto.* Discovered in 2003, it became the most distant object yet observed in the solar system, and the largest solar body to be found in over 70 years.

Its orbit is highly elliptical - taking it from 76 AU to about 975 AU over the course of 12,000 years.

In 2076, it reaches perihelion (its closest point to the Sun) and a series of unmanned probes are sent to explore it.

2079

Practical flying cars are entering the consumer market

Anti-gravity propulsion has been under development for almost a century now.* Initially seen in military applications, it eventually found its way to the consumer market. Here, it began showing up in various luxury items and devices, such as hoverboards and floating recliners.

Further refinement of this technology - together with advances in AI, microjets and collision avoidance systems - has led to the dawn of a new era in personal transportation. In the late 2070s, it is not uncommon to see what citizens of earlier decades might describe as "flying cars" moving through cities.

In fact, these are light-duty vehicles based on earlier military VTOL (Vertical Take-Off and Landing) craft, but with slimmed down functionality and costs. They come in a variety of models and sizes, but are typically around 4 metres wide, and limited to a maximum of one or two passengers. By the end of this decade, they are becoming cheap, safe and numerous enough to be regarded as a mainstream form of transport.

The craft have a number of advantages over established forms of mobility. Since they float above the ground, they can access terrain and environments that would easily defeat traditional automobiles. This makes them popular with adventurers and explorers. They are also substantially faster than normal cars, able to reach several hundred kilometres per hour if necessary. They are more versatile and manoeuvrable than aeroplanes and can utilise a much greater volume of airspace. Since the traffic they generate is decentralised and there is so much available airspace, this makes them safer than both cars and aeroplanes, too. Collisions are almost unheard of, in any case, due to the onboard software and AI.

In addition, they use considerably less fuel than earlier forms of transport and require less maintenance.

Some of the more expensive models are capable of reaching low Earth orbit for short periods. Others feature striking designs, often personalised by their owner - such as holographic decals and other accessories. These craft are being used by many businesses too (especially for rapid delivery of goods), as well as police and ambulance crews.

Further developments in anti-gravity will lead to bigger, more sophisticated versions - including recreational vehicles serving as truly mobile homes. Many previously inaccessible parts of Earth will become inhabited thanks to this, such as mountains and remote islands.
