Future technology: 22 ideas about to change our world.
The future is coming, and sooner than you think. These emerging technologies will change the way we live, how we look after our bodies and help us avert a climate disaster.
Technology moves at a relentlessly fast pace in the modern world. It can sometimes feel like every single day there are new technologies and innovations that will change our futures forever. But in a steady stream of announcements about new massive futuristic technological upgrades and cool gadgets, it is easy to lose track of the amazing ways the world is progressing.
For instance, there are artificial intelligence programs writing poems from scratch and making images from nothing more than a worded prompt. There are 3D-printed eyes, new holograms, lab-grown food and brain-reading robots.
All of this just scratches the surface of what is out there, so we've curated a guide to the most exciting future technologies, listing them all below.
Necrobotics
Sand batteries
Not every technology bettering our future has to be complicated, some are simple, yet extremely effective.
ChatGPT, creating poems from scratch, explaining complex theories with ease and having full-length conversations like it is a human.
ChatGPT is powered by a software known as GPT-3, trained on billions of examples of texts, then taught how to form coherent and logical sentences.
ChatGPT is an example of AI and its future. It has proven its ability to make completely new websites from scratch, write entire length books and even make jokes... although, it clearly still hasn't mastered humour yet.
Boom-free supersonic flight
NASA’s X-59 ‘quiet’ supersonic aircraft is set to take to the skies for its first test flight at the Armstrong Flight Research Center later this year. The plane is currently being assembled in a hangar at Lockheed Martin’s Skunk Works facility in Palmdale, California.
Its fuselage, wings and tail have been specially designed to control the airflow around the plane as it flies, with the ultimate aim of preventing a loud sonic boom from disturbing people on the ground below when it breaks the sound barrier. If the initial test goes to plan, the space agency aims to carry out further test flights over inhabited areas to gauge the public’s response to aircraft in 2024.
Self-healing 'living concrete'
Scientists have developed what they call living concrete by using sand, gel and bacteria.
Researchers said this building material has structural load-bearing function, is capable of self-healing and is more environmentally friendly than concrete – which is the second most-consumed material on Earth after water.
The team from the University of Colorado Boulder believe their work paves the way for future building structures that could “heal their own cracks, suck up dangerous toxins from the air or even glow on command”.
Fuel from thin air
Chemical engineers from Switzerland’s École Polytechnique Fédérale de Lausanne have created a prototype device that can produce hydrogen fuel from the water found in air.
Inspired by leaves, the device is made from semiconducting materials that harvest energy from sunlight and use it to produce hydrogen gas from water molecules found in the atmosphere. The gas could then, potentially, be converted for use as liquid fuels.
Internet for everyone
We can’t seem to live without the internet (how else would you read sciencefocus.com?), but still only around half the world’s population is connected. There are many reasons for this, including economic and social reasons, but for some the internet just isn’t accessible because they have no connection.
Google is slowly trying to solve the problem using helium balloons to beam the internet to inaccessible areas, while Facebook has abandoned plans to do the same using drones, which means companies like Hiber are stealing a march. They have taken a different approach by launching their own network of shoebox-sized microsatellites into low Earth orbit, which wake up a modem plugged into your computer or device when it flies over and delivers your data.
Their satellites orbit the Earth 16 times a day and are already being used by organisations like The British Antarctic Survey to provide internet access to very extreme of our planet.
3D-printed eye tissue
Researchers at the National Eye Institute in the US have produced retinal tissue using stem cells and 3D bioprinting. The new technique may help scientists model the human eye to better understand – and develop treatments for – diseases and conditions that affect people’s vision, such as age-related macular degeneration (AMD).
The researchers created tissue found in the outer blood-retina barrier, which is the area AMD is known to start in, by printing stem cells taken from patients into a gel and allowing them to grow over several weeks. They are currently using the tissue to study the progression of AMD and are experimenting with adding additional cell types to model more of the human eye.
Car batteries that charge in 10 minutes
Fast-charging of electric vehicles is seen as key to their take-up, so motorists can stop at a service station and fully charge their car in the time it takes to get a coffee and use the toilet – taking no longer than a conventional break.
But rapid charging of lithium-ion batteries can degrade the batteries, researchers at Penn State University in the US say. This is because the flow of lithium particles known as ions from one electrode to another to charge the unit and hold the energy ready for use does not happen smoothly with rapid charging at lower temperatures.
However, they have now found that if the batteries could heat to 60°C for just 10 minutes and then rapidly cool again to ambient temperatures, lithium spikes would not form and heat damage would be avoided.
The battery design they have come up with is self-heating, using a thin nickel foil which creates an electrical circuit that heats in less than 30 seconds to warm the inside of the battery. The rapid cooling that would be needed after the battery is charged would be done using the cooling system designed into the car.
Their study, published in the journal Joule, showed they could fully charge an electrical vehicle in 10 minutes.
Artificial neurons on silicon chips
Scientists have found a way to attach artificial neurons onto silicon chips, mimicking the neurons in our nervous system and copying their electrical properties.
“Until now neurons have been like black boxes, but we have managed to open the black box and peer inside,” said Professor Alain Nogaret, from the University of Bath, who led the project.
“Our work is paradigm-changing because it provides a robust method to reproduce the electrical properties of real neurons in minute detail.
“But it’s wider than that, because our neurons only need 140 nanowatts of power. That’s a billionth the power requirement of a microprocessor, which other attempts to make synthetic neurons have used.
Researchers hope their work could be used in medical implants to treat conditions such as heart failure and Alzheimer’s as it requires so little power.
