Neutral driving, particularly at downhill road section, has become something of a fashion among public transport minibus drivers and general motrists as a means to cope with the ever-rising cost of fuel.

This is despite the fact that there is no real consensus as to whether neutral driving offers any savings.

Experts argue that neutral driving can inflict damage onto the brakes and engine and can result in the driver failing to control the vehicle leading to accidents. They argue that driving a vehicle downhill saves a negligible amount of fuel, and poses several risks especially if the vehicle is traveling at a speed over 40 kilometers per hour.

The company is in talks with Proton, the national Malaysian car-maker to produce the cars at their facilities in South East Asia. It is also in negotiations with two other, as yet unnamed, auto manufacturers from Germany and the U.S.

Speaking at a prototype viewing at the Proton test circuit in Malaysia, Detroit Electric’s Chief Executive, Albert Lam said, “We believe in affordable electric vehicles for the public. That is our dream … to find innovative ways to counter global warming.”

The cars, a sportscar, a sedan and a subcompact car, will feature a li-ion battery with a range of 200 miles on a single 7-8 hour charge and a total life span of 125,000 miles. They will also contain electric motor technology produced in-house. According to Chief Scientist Frits van Breemen-Schneider, the motor is 4 to 12 times lighter than exisiting designs, giving it a superior power-to-weight ratio. This means that it can produce 5kw of power per kilogram, whereas the best electric car in existence can only currently produce 0.25 kw per kilogram.

A new report by the Massachusetts Institute of Technology (MIT) Energy Initiative predicts that a 30-50% reduction in fuel consumption is possible in the US over the next 25-30 years. Initially, this will be achieved through improved gasoline and diesel engines and transmissions, gasoline hybrids and reductions in vehicle weight and drag. In the longer term, the study concludes that plug-in hybrids and, later, hydrogen fuel cells may begin to have a significant impact on fuel use and emissions.

The report, ‘On the Road in 2035: Reducing Transportation’s Petroleum Consumption and GHG Emissions,’ summarizes the results of an MIT research project that assessed the technology of vehicles and fuels that could be developed and commercialized during the next 25 years.

The research team assessed the effect of new vehicle and fuel technologies on the performance, cost and lifecycle emissions of individual vehicles. It then assessed the effects on the total on-the-road fleet of introducing these technologies using “plausible assumptions about how rapidly they could be developed, manufactured and sold to buyers to replace existing vehicles and fuels or to add to the existing fleet.”

Other key findings include:

Your often too generous uptake of food and fuel for transport is actually placing a great strain on already depleting world resources, according to some British researchers at the London School of Hygiene and Tropical Medicine.

This may be too warm to handle… The finding adds that what compounds the weighty problem is that obese and overweight people require more fuel to transport them and the food they eat, and the problem will worsen as the population literally swells in size, adding to food shortages and higher energy prices.

By 2015, 2.3 billion adults will be overweight and more than 700 million will be obese, according to current World Health Organization (WHO) projections.

In modern times, trade between North and South has seen an increasing volume of trucks making the long, slow journey through narrow valleys, high passes, and long tunnels, many of which twist and spiral their way through the rugged mountain terrain. At the beginning of school holidays, tailbacks at the entrance to the 15 mile Gotthard road tunnel can reach 30 kilometres as droves of Northern Europeans migrate South for the food, wine and sunshine of Italy.

Concerned by the consequent increase in pollution (amplified as the narrow valleys trap particulate emissions from cars and trucks, which threatens the balance of delicate alpine eco-systems), the Swiss voted in 1994 to limit trans-alpine freight transport to 650,000 trucks per year. Achieving this will involve a massive engineering project, with 2,000 people working on the new Gotthard Base Tunnel, 24 hours a day, 365 days a year.

So how, does the eco-option for crossing this massive and barren landscape stack up against more modern technologies? This is a question posed regularly at EcoWorldly and I recently had the opportunity to put it to the test during a journey which took me from the ‘Gateway to the Sahara’ in Douz, Southern Tunisia, to Matmata, a desert village of cave dwellings famous for providing the location for Luke Skywalker’s home in the Star Wars movies.

(Note: the author only discovered this fact after arriving - this was not a pilgrimage.)

Our local guides presented us with two options: The camel - trusty ship of the desert, as used for centuries by desert dwellers, and the equally ubiquitous Toyota Land Cruiser 4×4 – the motor vehicle of choice for those needing to travel across challenging terrain.

We gave both modes of transport a thorough workout in an attempt to compare our eco camel against it’s more modern counterpart, making assessments on comfort, emissions, speed, reliability, off-road capability and fuel consumption. The testing process consisted of two days of travel across the desert by camel, camping overnight in the dunes, followed by a further day’s journey in the Land Cruiser.
