The increased need for, and the implementation of renewable or clean energy, questions the premise of its safety and reliability because it brings about the possibility of being threatened by hackers by way of theft or cyberattacks. The magnitude of real-time data and the distributed generation of energy make for easy gateways. Take charging an electric car, for example — a group of such vehicles are ultimately connected to a larger power unit, which can, if jeopardized, compromise the grid of an entire city.
Nerd alert: sci-fi has finally found a place in our lives; it looks like we’re going back to the future!
We’ve all heard a lot about Elon Musk and the future plans of his companies, particularly that of SpaceX, in recent times. For example, SpaceX’s next generation is reportedly going to bring extraterrestrial travel – and maybe even colonisation – to the masses in the next decade. Tesla, on the other hand, may have more down-to-earth goals.
The high levels of carbon dioxide (CO2) found in the Earth’s atmosphere is a consistent environmental and socioeconomic problem. Many scientists assert that it is a major contributing factor to overall global temperature trends. Even if this was not the case, it is also a prominent air pollutant, which affects the quality of life and respiratory health of millions worldwide. Some authorities have attempted to tackle abnormal ambient CO2 levels through such methods as carbon emissions taxes or the promotion of low-carbon transport solutions.
Smart home devices are becoming increasingly popular. They are marketed as electronics that can take the work out of monitoring your home, doing your shopping, turning on heating and monitoring your energy consumption. These Internet of Things (IoT) based products connect your home to the online world, by making shopping for things on websites such as Amazon easy or even automatic. However, it can be disappointing when you take a new connectable home and it doesn’t ‘talk’ to the other devices around it.
Elon Musk and his company Space X have some grand plans for the future of humanity – with details released last night, at 12:30AM ET, at the International Astronautical Congress held in Adelaide, Australia.
Graphene is a fascinating and relatively novel material that may have a whole range of applications in the areas of electronics and engineering in the near future. It is a superconductor that has recently demonstrated the ability to co-exist with silicon to enhance the capabilities of this complementary metal-oxide-semiconductor (CMOS). These capabilities include photonics: for example, silicon/graphene transistors have recently formed the basis of a sensor that can ‘see’ visible, IR and UV light simultaneously.
Some of us may think of robots as machines we’ve created to mimic human or animal motion, gait, gestures and forms. They are also very often designed to manipulate things in a way that approximates the human ability to do so, in order to complete tasks and automated processes. However, there are engineers and scientists who assert that robots would be more effective, adaptable and useful if they conformed to more unique or interchangeable form factors.
Solar energy involves using highly-specialised and engineered power cells to harvest the energy of sunlight and convert it into electricity that can be used by conventional appliances. Over the last 20 years, this concept has morphed from an unlikely pipe dream into a nearly-standard component of energy use in new buildings. Installations of sunlight-collecting panels in large numbers have become part of the everyday electricity grid in several countries, including China and Spain.
Most of us now realise that fish stocks in the world’s oceans are at an all-time low. But what many people fail to understand is that the age of the remaining fish within those stocks also has an important impact on the health of these marine communities, which we rely on as an important source of food.
The traditional route of taking medicines in tablet form for certain conditions could potentially be replaced by a small device similar to a pacemaker, researchers claim. The device is roughly the same size as a pacemaker, but instead of being implanted by the heart, it sits just below the left collarbone. The idea is that the device stimulates the vagus nerve, which runs from the brain to the abdomen and is responsible for maintaining our heart rate, as well as relaying signals to and from our spleen, lungs and digestive system.
Synthetic facial recognition is demonstrably making the transition from action or spy movies to real life. This technological revolution is based on the ability of cameras to pick up the image of a face to process, analyse and ultimately identify people based on their facial characteristics. Companies such as NEC believe that computerised facial recognition can form the backbone of a modern security system, be they public or corporate.
Imagine a classroom where a robot stands in front of a group of students, setting them individualised tasks and making sure each student completes this to the best of their ability. A human teacher is on hand to check on students’ work and to maintain discipline if necessary, but it’s the robot which will be responsible for creating learning plans for each student as well as monitoring their progress both within a lesson and over the course of an academic year.
Toys are an inseparable part of our childhood years, no matter where on the Earth we live or how poor or rich we are. The difference comes in the materials used to make the toys, and whether they are especially designed to be used as a toy with an educational purpose, or an ordinary object turned into a toy through the imagination of a child. Many of us remember folding an ordinary piece of paper into an intricate airplane and watching with delight as it flies through the sky. The toy market however, has advanced apace, driven by the technological revolution in our everyday life.
We are in need of novel new fuel sources for the future, with one potential solution being the possibility of converting fatty acids to hydrocarbons using an algal enzyme which is activated by light. The ability to scale this recently discovered reaction to an industrial level could well provide an environmentally friendly new source of hydrocarbon energy.
Storing natural energy sources like wind and solar energy is highly unpredictable, thus hastening the need to resort to alternate means. While some countries have taken to stockpiling hydroelectricity, other nations face challenges due to reasons like water scarcity or poor accessibility. Meanwhile, the daily requirements for energy via televisions, air conditioners, water heaters and so on, continue to escalate among both our homes and places of work.
Currently, one of the major drawback of electric cars is that they have a relatively small range of travel before they need to be recharged. This can take several hours which definitely cuts into the time required to travel long distances. Couple this with an expensive price tag and it seems as though it’s still going to take a bit more time before electric cars become more mainstream.
The flying car is not a thing – although technology enthusiasts born in the 1980s or later may be disappointed by that fact. Many of us may be secretly dissatisfied that having the choice between taking to the roads or the air is not an everyday amenity as yet. The technology that makes the personal or family flying vehicle is still in its very early stages. The most recent Consumer Electronics Show (CES) exhibitions showcased a few single-person planes or helicopters, but these were either concept showcases or prohibitively expensive.
The idea of teleportation is no more just in sci-fi movies or fiction books, it has become a real-world phenomenon! Also called teletransportation, this power is defined as the transfer of energy without traveling any physical space.
