What interests me about this scheme is that it hints at a possible solution to the problems currently associated with the electric car. The mass roll out of the electric car is dogged by several persistent problems. There’s the limited battery life, high maintenance costs for the battery, as well as charge times in the order of hours (by contrast one can refuel a petrol powered car in minutes and a LPG tank in under an hour). The idea of using electric cars plugged into the grid to even out the peaks and troughs in a renewables dominated electric grids is often touted, and this article here from the IMECHE suggests the basic concept is sound (given a few changes to how the grid is managed and power distributed of course!). However, the effect that such a proposal would have on the battery life of cars (given that they’ll be being charged and discharged much more frequently this leads to a slight increase in the wear out rate of batteries) has not been adequately addressed.

But to me the “problems” with the electric car, or indeed hydrogen fuel cell powered cars for that matter, is only a problem so long as we remain wedded to the idea that the global car fleet need to be privately owned by individuals. That is to say that we are expected to purchase and maintain a car for ones own personal use, even though it spends 80-90% of its life parked up by the side of the road gathering rust. By contrast if we all share our cars via some sort of city wide rental system (not unlike the proposed Paris system except potentially for longer periods), or rent them of off a private company, then many of the above problems simply disappear. The maintenance and replacement issues with batteries become an issue for the car leasing organisation not the user. While they will ultimately need to pass on such costs to the end user, such costs will be greatly reduced due to the benefits of improved economies of scale. In essence it becomes more of a long term business decision, and assuming that they keep the car in more regular use and hired out (than a privately owned car that again spends 80-90% of its working life idle) , that should reduce those costs to a reasonable level.

The problem often highlighted regarding the lengthy charge times for electric cars (in this article a BBC reporter takes 4 days to drive a electric car from London to Edinburgh, largely due to the amount of time the car had to spend charging up the battery) also becomes less of a problem if they’re merely being rented temporarily than it being one’s own personal vehicle, as presumably there will always be charged up cars available on every street corner (might get a bit harder at peak times, but you’d be a fool to assume you can get a car at such times if not booked in advance, much like you’d a fool to think you’ll get a taxi just by putting you’re hand up at peak rush hour). You simply pick the one nearest to you, tap your fob from the leasing company on special panel (which unlocks the car and charges you’re account) and hop in, and plug it back it when you’re done. The issue mentioned above with regard to an increased wear in batteries due to using the batteries to balance out the gird is also resolved. The leasing company hires out the car’s and their batteries to the power utilities, who would presumably compensate them for the increased battery wear in return, as well as this providing a useful revenue stream for the leasing company to further reduce the hiring costs to the customers. Similarly the customer is rewarded if he keeps the car he’s hired plugged in while its parked up with say a discount in the rental costs, or maybe free parking spaces. Suddenly the electric car sound like a much more viable idea when you look at it like this.

Also the other problem with electric cars, that being the current limited range of such vehicles, becomes less of an issue. The vast majority of journeys undertaken by people today are less than 25 miles (at least in Europe anyway, America’s a slightly different kettle of fish) easily within the range of an electric vehicle. But its this “threat” of the occasional long journey that enforces the purchase of petrol powered cars instead. Currently with electric vehicles via the private motoring option you would be required to own two cars, one electric and one IC engined, which isn’t really convenient for someone with limited funds (i.e. can barely afford one car!) or parking facilities. Now, with shared ownership, if you suddenly find yourself needing to go on a long journey one that cannot be performed either by public transport or an electric car, you simply opt instead to hire one of a small fleet of IC or hybrid engined cars instead.

Such a scheme of collective car ownership would also solve a number of other problems. For example, I highlighted in a prior post the issue of “planned obsolescence” where products, notably cars, are often specifically designed with short operating lives. This is done both in order to increase sales (shorter operating life means demand for more cars), but also because consumers by and large demand products that are cheap and which they don’t actually intend hanging onto for very long. Obviously for a car leasing firm the purchase cost of a car matters little, it’s the overall lifetime cost of ownership that’s important. They will thus purchase cars with longer operating lives, more fuel efficient engines, lower maintenance costs and ultimately lower disposal costs, in preference to cars with a lower initial purchase costs but shorter lives (and thus higher life time costs). Now if a large portion of the motor cars worldwide are being bought by such organisations, then obviously the manufacturers will quickly change they’re tune and start building cars with longer operating lives, that are easier to maintain and more fuel efficient. This will greatly reduce the amount of resources that needs to get put into building cars in the first place and the pollution this causes, nevermind the benefits of reduced air pollution and elimination of tailpipe emissions that electric cars already provide. Also given that leasing companies will be trying to keep their cars constantly in use (or parked up and charging), the end result is you will need substantially less cars to support a nation’s motorists, which brings all sorts of benefits (less parking space required, less road building, less accidents, less thefts, etc.)

Also there’s been much talk recently about redressing the imbalance that is the absurd subsidy society gives to private motoring (in terms of the government paying for building the roads, maintaining and policing them, providing fire and emergency services cover, paying for the costs of climate change, and securing oil resources, but getting only a fraction of all of this back in road and petrol taxes). Congestion charges or a system of road pricing is often raised as fair and egalitarian way of resolving this issue. However, the problem with both is always implementing it (who in their right mind is going to fit a government GPS tracker to their car just so “big brother” can track and tax you!). Obviously, if the majority of cars on the roads are leased from companies (or local councils) it’s a simple matter of fitting them all with GPS units from day one.

Perhaps more critically this idea of “national car sharing” also helps to square the circle as far as public transport. Let be realistic for a minute. Public transport is a very efficient way of moving lots of people from A to B, but what if you want to go to C and live at D? Consider, its possible to go from London (Kings Cross) to say, Achnasheen (a small rural railway station in the middle of the Scottish highlands) in 10 hrs and 15 minutes, including stops (according to national rail enquires). Driving that same distance (596 miles) is doable in 10 hrs 25 minutes, according to Google maps, excluding stops (and to be realistic driving that far in one day, nevermind non-stop wouldn’t be a good idea, not unless you want to risk falling asleep at the wheel!). However, the problem is what do you do when you get to Achnasheen? Suppose you’re ultimate destination is down some remote highland glen or say, Torridon, a small village about 15 miles away down a very scenic valley surrounded by mountains (some of the oldest exposed rocks in the British isles in fact). There is no direct bus from there to Torridon. And in any event the timetable says you’d be arriving at 19:15 at night. If you’re a keen cyclist (like me) you could try biking it (but its fairly hilly!) but that’s not much good if you’re 60 years old or with kids and have lots of luggage. Furthermore getting bikes on trains these days isn’t easy. A taxi would be difficult to arrange and likely expensive. And of course you need get back to the station for the return journey to London! And what happens if you get back to the station and find the train has been delayed or cancelled or you simply missed it? And suppose that rather than living in central London, you live in a small Cothswold’s village and you thus have the same sort of problems at the other end!

Consequently it’s no surprise why so many people choose to get in their cars and drive the entire length of such a journey, even though strictly speaking a car is only necessary for the first and last 5-10% of the journey distance. This is why even in situations where it’s cheaper to use the train than drive, many people still opt to drive. Indeed on that point I would note that the cheapest single ticket for that case study journey I mentioned above was £173.50 while Google quotes an estimated driving cost of £114.40! The reason why the car triumphs over public transport every time has nothing to do with anything you’ll hear Jeremy Clarkson fluster about (or faking on Top Gear), it has everything to do with convenience and the assurance that you have a car sitting there ready to take you wherever you want to go at the drop of a hat.

But car sharing would allow us to square this circle. Now when I get off the train at 19:15, I simply hop in a car, drive onwards to my final destination, and plug it back into the nearest charge point. When I’m done, I hop in a car drive back to the station, plug it back in, fall asleep on the train, and hop in another car the other side which takes me home. Now nevermind cost, that’s the sort of system with a level of convince that stands some chance of temping people into travelling more by public transport. And if the usage of public transport goes up, then ticket prices begin to fall substantially (look at Ryanair, ever wonder why they can offer flights for a euro? Its because they make sure their planes are constantly in the air and as fully loaded as possible…oh! and btw I’m not related to these guys, “Ryan” is a very common Irish name so don’t e-mail me complaining about the time they lost you’re bags!).

Now some people will inevitably say, wait give up my own personal car for some sort of “collectivised” car ownership system…sounds a bit commie! Nobody’s suggesting we ban private cars or anything like that (well, not immediately anyway!). Inevitably the above system will not suit everyone’s needs or tastes. A travelling salesman (in say solar panels) or a farmer in a remote rural area, or a doctor or a plumber (plus all his tools!) will all probably find that they need they’re own personal and privately owned vehicle. And indeed while we’re at it, building electric vehicles capable of meeting these people’s needs would be technically challenging, nevermind electrifying long distance trucks, aircraft or cargo ships. Inevitably quite a bit of our transport network will still have to remain fuelled by oil in the short term, then probably biofuels taking over later, possibility eventually being superseded by hydrogen vehicles longer term. No doubt some petrol heads with more money than sense will still want they’re boys toys and I’m quite sure Ferrari and Porsche will still be around to satisfy their needs (i.e. sell them over-priced “anatomical extensions”). Although they may find, given that the welfare rug of public subsidy has been pulled from underneath them, such private car ownership will now be somewhat more expensive. But for the vast majority of us such a car sharing system would offer numerous benefits and advantages.

I would finally point out that robotic car technology, that being cars that can drive themselves, is progressing at quite a pace. One could see a convergence in the future between improving electric car technology and artificial intelligence, which could ultimately us all permanently relegated to the passenger seats. Indeed the BBC has another video here about a scheme using driverless pods in Heathrow airport, although these run on dedicated tracks. I’ve been hearing about such PRT systems for quite sometime, and while I’m not entirely convinced about them yet, certainly they could figure quite significantly in the future. If the price could be reduced and these pods developed such that they could run on the road network (even if only for short distances) this would truly close the loop between public transport and personal automotive transport.

Robotic cars offer numerous advantages, notably the fact that they don’t get drunk or distracted by the kids fighting in the back and run over granny’s, they provide better fuel economy and increased engine life (robots aren’t constantly sitting on the brakes and then speeding up or forgetting to change gear, etc.), they don’t get lost and refuse to look at a map, plus you can run robotic cars in bumper to bumper traffic at 70 mph!

Obviously if machines are going to start driving cars it makes little sense for us as individuals to own them anymore, far better to delegate such responsibilities and the maintenance of such vehicles (to avoid some very literal blue screen of death moments!) to a suitable authority (private company or government backed leasing scheme).

Bottom line, if the automobile is to survive the end of the age of oil, we have to adapt our car ownership system to suit the needs of the technologies that replaces oil, not try to adapt the technology to our peculiar and outdated traditions.

The car industry is currently undergoing a green revolution, with a number of exciting new technologies vying to challenge the predominance of petrol and diesel and put an end to the internal combustion engine’s negative effects on the environment.

For many years now, private cars have been a favourite target of environmental campaigners, mainly due to the harmful emissions that all internal-combustion engines release into the atmosphere. Their effect was illustrated starkly several times in the 1970s when ‘car-mad’ cities like Los Angeles and London were frequently shrouded in a thick, polluting smog. Car manufacturers have been working on improving their products’ environmental credentials for quite some time now. The most significant developments of the last quarter of a century include the rollout of unleaded fuel, as well as the mandatory fitment of catalytic converters, which remove many of the most harmful elements of vehicle exhaust fumes, to all new cars. But as the 21st century dawned, talk of diminishing oil supplies and the ongoing threat of global warming has incentivised both carmakers and governments to accelerate development of the technologies that will one day take over completely from those in the cars for sale today, which remain dependent on fossil fuels.

Hybrid cars, as the name suggests, represent a half-way house between traditional petrol- and diesel-engined models and the next generation of electrically propelled vehicles. Essentially, a hybrid car is one that combines an internal-combustion engine with an electric motor, powered by large batteries, to provide propulsion. There are two distinct forms of hybrid drivetrain: parallel and series. In a parallel hybrid, both the combustion engine and electric motor are connected to the transmission. Both engines are capable of powering the car, either at the same time or separately. In a series hybrid, only the electric motor is connected to the transmission, and it is solely responsible for propulsion. The combustion engine is connected to a generator to recharge the electric motor’s batteries; it is not responsible for any motion. There are already a number of hybrid cars for sale right now from various manufacturers, with the most popular and recognisable being Toyota’s Prius, now in its third generation. Japanese rival Honda has recently launched its second-generation Insight hybrid, and Toyota’s upmarket brand Lexus offers hybrid versions of its luxury SUVs and executive saloons. These are all parallel hybrids, but General Motors in the US is currently developing the Chevrolet Volt, which should be among the first series hybrid cars to go on sale to the general public.

In the longer term, however, it is likely that hybrids, which still require some fossil fuel, will be superseded by exclusively electric-powered cars. Many governments worldwide are undertaking initiatives to get electric cars for sale to the public as soon as possible. Indeed, a Norwegian minister has proposed banning the sale of all new petrol and diesel cars from 2015! The main obstacle to the growth of electric cars is the fact that their batteries need to be recharged with mains electricity, but seeing as they cannot yet store enough energy for long-distance travel, extensive recharging infrastructure will have to be put in place before the use of electric cars becomes widespread. This is something governments will have to make happen, while the manufacturers concentrate on prolonging the life of batteries and improving their recharging speed. Governments will also have to ensure that their national power grids produce electricity using environmentally friendly resources such as water, wind or the sun.

But electric cars won’t have the roads of the future all to themselves. A rival technology has emerged in the shape of hydrogen fuel cells, arguably the most groundbreaking method of alternative propulsion currently being developed. A hydrogen-powered car has a fuel tank that is filled with hydrogen in the same way a petrol-engined car’s tank is filled with petrol. The hydrogen reacts with oxygen inside the engine to produce electricity and water, which in turn power the car’s electric motor. The Honda FCX Clarity is probably the most widely known hydrogen fuel-cell-powered car, as it has been on limited trial sale in the United States and Japan since late last year. It’s powered by a 134hp, 57-litre hydrogen fuel-cell stack, and also uses a 288-volt lithium-ion battery. On a full tank of hydrogen, the Clarity can travel up to 280 miles, and, most importantly, the only waste product it produces is water. As with electric vehicles, the growth of hydrogen-fuelled cars is dependent on a network of suitable refuelling points being rolled out.

With development of all these innovative technologies currently proceeding at breakneck pace, it looks likely that it won’t be too long before none of the cars for sale on dealers’ forecourts have internal-combustion engines under the bonnet, something which will make a massive difference to the impact humans currently have on the planet’s environment.

Hybrid cars have well and truly entered the consciousness of the car-buying public in the last few years, as ‘greener motoring’ has become a hot topic. We have all heard that these cars are more eco-friendly than ‘normal’ vehicles and recently it has became trendy to own a hybrid. But how many of us know just what is under the bonnet of a hybrid car? Let’s take a look at exactly how a hybrid works and why it’s a greener option than a regular car.

Put simply, a hybrid car is one that combines an internal-combustion engine with an electric motor, powered by sizeable batteries, to propel the vehicle. There are two types of hybrid car: parallel and series (also known as serial). In the first case, both the combustion engine and electric motor are connected to the mechanical transmission, which means that both engines are capable of powering the car, at the same time or separately. In series hybrids, only the electric motor is linked to the transmission, and it alone propels the car. The combustion engine is connected to a generator and is used purely to recharge the electric motor’s batteries.

Nowadays, most hybrids use a combination of both systems, with power-split devices incorporated into the CVT transmission. The electric motor and the combustion engine are used to provide propulsion and the combustion engine is also connected to a generator that charges the batteries when needed. The device decides which motor to run and how to split the available power. The application of this system allows the use of an internal combustion engine with less power, which, in turn, reduces fuel consumption and emissions. So, when you’re driving at low speed, e.g. in heavy traffic, only the electric motor is used. As speed increases and the demand on the electric motor becomes too great, the combustion engine is started to not only aid in the propulsion of the car but also to recharge the batteries.

Another piece of technology that makes hybrids more efficient than regular vehicles is their ability to make use of the kinetic energy that would usually be lost while braking. When the brakes are applied in a hybrid car, the energy released is stored and used to recharge the electric motor’s batteries.

Today, there is a wide range of cars that incorporate these innovative systems. Last year, there were more hybrid launches than ever before as car manufacturers went head to head to try to meet the increased demand for these vehicles. The most popular and well-known hybrid model is the Toyota Prius; however, there are other models that are also worth attention. Honda offers a hybrid version of the popular Civic and there is also a brand-new original hybrid model from the firm, the Honda Insight. Meanwhile, more luxurious options are offered by Toyota’s upmarket Lexus division, in the shape of the GS450h, LS600h and RX400h.

European car makers Pininfarina and Bolloré have created BlueCar, a hybrid vehicle powered by lithium-polymer batteries. According to the car makers the first units of this electric car will be delivered in about a year. Leases for the BlueCar will be available in six European countries at a cost of €330 per month.

BlueCar will be able to be charged from a standard domestic main socket and will have a range of 250 km (153 miles). The car will have a top speed of 130 km/h (80 mph) and will feature potent acceleration, reaching 60 km/h from a standing start (0 to 37 mph) in 6.3 seconds. According to Pininfarina and Bollore the BlueCar will be able to run about 30 km (20 miles) on only a charge of a few minutes. The car will also be equipped with solar panels on the roof to help power the electrical equipments as well as its heating and air-conditioning system. Critics say the solar panels are a cool addition to the car but that it will make the car more expensive.

The lithium-polymer battery inside the BlueCar, also called LMP, will have an expected lifetime of about 200,000km (125,000 miles). BlueCar is also equipped with a battery pack and supercapacitors to capture energy when the car is braking

“In an electric car, supercapacitors draw and store energy generated while the car is braking and feed it back into the system when the car moves off again. The result is greater acceleration, increased range and a longer lifespan for the car’s battery.”

The seat covers are leather-like covers produced from vegetable sources. The BlueCar will be, according to early plans, only available in France, Italy, Germany, United Kingdom, Spain and Switzerland. Production numbers are set to 10,000 cars in 2010, 20,000 in 2011 and 30,000 in 2012.

Tesla Motors, the electric car startup company, recently unveiled their new Model S car in Los Angeles. The electric prototype car will cost $49,900, after a $7,500 tax credit and will be available for purchase in late 2011.

“Model S doesn’t compromise on performance, efficiency or utility — it’s truly the only car you need,” said Tesla CEO, Chairman and Product Architect Elon Musk. “Tesla is relentlessly driving down the cost of electric vehicle technology, and this is just the first of many mainstream cars we’re developing.”

The Tesla Model S will have a range of 300 miles with the possibility to buy less expensive batteries that will give you a range of 230 or 160 miles. The charging time is expected to take 4 hours, or 45 minutes by using a “quickcharge”. The car will do 0-60 mph in less than six seconds (5.6 seconds), a sport version of the car is promised to achieve 0-60 mph “well below five seconds”.

“Model S costs half as much as a Roadster, and it’s a better value than much cheaper cars,” Musk said. “The ownership cost of Model S, if you were to lease and then account for the much lower cost of electricity vs. gasoline at a likely future cost of $4 per gallon, is similar to a gasoline car with a sticker price of about $35,000. I’m positive this car will be the preferred choice of savvy consumers.”

The car will also have access to internet via 3G and be equipped with a 17-inch LCD screen in the center console. You will also be notified by SMS when the Model S has fully charged its batteries.
