Research Papers About The Duture Of Cars

Uber has shaken up the taxi industry and is trying to put driverless cars on our roads. Now the company aims to have flying ride-sharing vehicles in our skies by 2020.

Uber is not alone in working towards flying cars. But is this realistic, or just marketing hype?

To many of us, the concept of flying cars is synonymous with the future, just like silver jumpsuits and gourmet food in the form of a pill. Those dreams have not yet materialised so what about flying cars?

How is this a car?

The classic idea of a flying car was just that: a car that could somehow fly.

In fiction, the author Ian Fleming was a fan of flying cars, writing his novel Chitty Chitty Bang Bang around the concept in 1963. He also included a flying car in his James Bond novel (1964) and subsequent film, The Man with The Golden Gun. These concepts are based on a car with wheels that can drive on the road but is also capable of flying when required.

Science fiction writers and directors have often dispensed with the need to have future vehicles ever drive on the road. Instead, the “cars” are simply small aircraft such as the one Anakin Skywalker used in the Star Wars film Attack of the Clones.

The recent flying car announcements vary in type from single-seat, multi-copter drone-type aircraft, to road-style cars that turn into light aircraft and small flying boats that hover above the water.

It would appear that almost any small flying vehicle capable of transporting a person is now referred to as a flying car. But clearly they are really just a kind of small aircraft.

How safe?

Any potential passenger will want to know: “How safe is this contraption?”

The likely answer right now is “not very safe”, as with all early-stage technology. Companies are working feverishly to make their aircraft “safe enough” in the hope of convincing regulators and governments that the vehicles can be entrusted with human lives.

But there are incredible safety challenges. One of the biggest is what to do when things go badly wrong.

With a normal car, you can often just slow to a halt and stop. But a flying car might fall out of the sky, killing not only its occupants but potentially bystanders too.

The Chinese company Ehang is proposing to equip its flying car service in Dubai with a parachute. This service will apparently take a single occupant from the roof of one Dubai skyscraper to the roof of another.

Should the parachute deploy, it is not clear whether the vehicle will have any way to control where it lands, or how safely.

In the existing aviation industry, much of the mechanics of flying is automated. Given the challenges of a person flying compared to driving a car, and the efforts to reduce human error in aviation, there is even more likelihood of flying cars becoming automated so that no human pilot is needed.

But there will be differences between existing aviation practice and flying cars. Passenger jet air travel owes much of its impressive safety record to improvements in aircraft maintenance procedures and our understanding of failures. It is unlikely that the business case for small flying cars will allow for such rigorous practices.

Instead, flying cars will be less complex than modern jets, and the latest demonstrators show exactly that.

The use of large numbers of small electric motors, such as in the Lilium all-electric aircraft, reduces the maintenance complexity drastically. It also provides an inbuilt measure of redundancy in case one motor fails.

How fast, how far?

Wouldn’t it be great to avoid the traffic and public transport congestion of our major cities? We think so.

For example, it currently takes 23 minutes to drive the 19km from our offices in Brisbane to the domestic airport, when traffic is freely flowing.

If we could fly from our office roof (and there is a pad on our roof that is ideally suited to deploying a flying car), the trip would only take 8 minutes.

We’d get a double boost, first from flying at an average speed of (say) 100kmh, and second by taking the straightest path, a mere 13km.

This example journey is well within the capabilities of the flying cars being demonstrated today.

Of course it may be that authorities mandate that we stick to flight corridors reserved for flying cars, so a direct route is not always an option. These corridors may be strategically located over low-risk areas of land that have minimal population.

How easy?

There are lots of things about flying cars that are hard, but some problems may become easier.

There is a lot more space available for cars when you when you have access to three dimensions for travel, as long as the navigation challenges are solved.

Using the several hundred metres of space above the ground means you can potentially have a lot less traffic congestion. You also don’t need to build and maintain expensive road infrastructure.

For self-driving flying cars, moving into the sky actually makes some aspects of planning and traffic control easier.

How much?

It is too early to know how the economics of flying cars will work.

Given the huge regulatory hurdles, the safety issues to overcome, and the lack of special infrastructure to support flying cars (such as take-off and landing areas and charging points for the all-electric aircraft), it is difficult to estimate what a trip should cost.

The current non-flying car ride-sharing companies such as Uber appear to be operating at a massive loss.

The price paid by the consumer in an Uber vehicle is reported to be on average less than half the actual cost of the trip, but the company is hoping to recoup some of these costs by implementing driverless cars. Given that there’s even more chance that flying cars will be driverless, maybe the economics will be favourable.

What would a consumer be willing to pay to possibly get to their destination in half the time? There’s at least one famous historical example in Concorde that posed that same question, and had safety issues. Sadly, its supersonic passenger flights are not available any more.

How long the before I can fly to work?

There is still so much to do before flying cars can become common. The technology has come a long way, mainly due to the rapid development of drones. But the technology of the flying machine itself is just one part of a very complex system.

Like ground-based self-driving cars, it’s likely that if they ever happen, flying cars will occur in certain priority areas first.

Imagine a cheaper but still expensive option for high-level executives, such as the Dubai proposal.

For the rest of us, we may already be walking around in silver jumpsuits and eating meals in a pill before we get to ride in a flying car.

Canada has committed to cutting GHG emissions 30 per cent by 2030 from 2005 levels. Can Canada's oil capital lead the charge? New research shows it's within reach with bold actions on several fronts.

Elon Musk is a master of keeping investors believing in the dream of Tesla, but analysis of the company’s output and financials reveal a darker picture.

There is a rapid shift in production of electric cars all over the world. But how will it benefit ordinary people?

The future of electric vehicles according to experts in the energy sector

The overall analysis of the results of the new Energy Market Barometer confirms that the road to a change in the dominant mobility model is still long.

Self-driving, shared, electric vehicles and increasing urban density represent four disruptions that will transform city life. But a transport utopia isn't a guaranteed outcome of their interactions.

Despite persistent buzz, the falling cost of electric cars isn't enough to guarantee sales in Australia.

There's a reason the next generation of cars look eerily familiar – and we may have a long wait for something completely different.

While other countries race into the distance, Australia is still on the starting grid when it comes to electric cars. Why so slow? Because we don't have a proper recharging network.

Australian vehicles have been accused of creating more emissions than their manufacturers advertise. But are Australian testing standards up to scratch?

Could we really reduce the number of vehicles on our roads from 37m to 9m?

Are mobility scooters harbingers of a future where small and versatile electric vehicles roam our cities?

Time's up for the internal combustion engine.

Governments racing to grab a lead in the global quest to position their countries for the car industry of the future.

The great dream of cars running on sustainable petrol has not bitten the dust. Here's why.

Volvo might be the first car company to go all-electric, but it's far from the market leader and petrol will continue to be relied upon.

Aston Martin has rarely been considered an eco-friendly brand, but it has announced an electric car of considerable heft.

When manufacturers are chasing sales and more and more customers are plugging in, is the writing on the wall for F1?

New research shows it only takes a few countries to kick-start the kind of global transformation required to meet the Paris Agreement’s long-term goals.

By boosting the demand for energy from the grid, electric cars could help create an incentive for more renewable energy investment, while smoothing over issues with supply and demand.

Standards, like electrical plugs, are usually so simple we don't even really notice them. But they're extremely important: Good ones can drive innovation; bad ones can stifle growth.
