Off-road bike rally

For my 40th birthday last year, my wife bought me what I can honestly say was the best present I’ve ever had.

I’d always wanted to have a go at off-road motorcycling but wasn’t serious enough about it to really get into it. And to be honest, I always felt a little nervous about the prospect, not being much of a biker.

Nevertheless, I took the plunge courtesy of a voucher for a day’s training and riding and what a day it was!

The training day was in deepest Shropshire and once we’d got the important but dull safety briefing and introduction to the bikes, we were off into the wilds.

All the requisite equipment and bike hire was of course included; the result being that you feel like the real deal; you just haven’t actually done it before!

My bike was a new Honda CRF450R and I can honestly say it was superb. After the necessary but boring training instruction, we were off across country. The trail took us across muddied fields, up and down some pretty steep hills, across rivers and streams, over gravel and rutted paths, and through woodland.

As the day wears on, you get more and more confident; for which read, you go a bit faster!

But the excellent Honda handled it all in its stride and I managed not to fall of which was a feat in itself.

The whole riding trip lasted about five hours. And to say it was exhilarating would be an understatement. I’d definitely do it again, but it didn’t grab me quite enough to go the whole hog and buy my own off-roader and start doing it really seriously. But for a once or twice a year experience and for a couple of hundred pounds, I’d thoroughly recommend it.

 

Human waste can power cars

Although biogas is a big thing in Swedish transport already, with over 15,000 cars, hundreds of buses and even a train powered by it, it’s generally associated with the use of organic waste like dead plants and animals, manure and kitchen waste, rather than human waste.
A car powered by human waste must be the ultimate example of sustainable human powered transport. There is a company in the UK that has already converted a VW Beetle to run on a combination of petrol and methane derived from human waste.  The prototype has been developed by a company called GENeco, which claims there is no reduction in performance with the BioBug compared to a conventional VW Beetle.
The equivalent of 70 trips to the toilet will produce enough methane to allow the BioBug to travel 10,000 miles – the distance an average UK driver covers in a year. The converted Beetle has two tanks – one for petrol and one for methane, but the petrol is used to start the car and then is there as a reserve to be used if the methane runs out.  In a way, it’s not really a true biogas car, it’s another form of hybrid. Yet projects like these show the potential for sustainable energy through processes such as anaerobic digestion – the breaking down of biodegradable material into methane gas.
So, how soon before we all fill up our car fuel tanks with a pipe connected from our bathrooms? Just think about how just a few years back, hybrid cars were considered a futuristic concept, while nowadays seeing a Toyota Prius or a Honda Insight is the most natural thing in the world. Obviously, it’s not that simple, and there is still a lot more development to be made in this kind of sustainable energy technology, before Honda cars include vehicles powered by human waste, but it’s just an indication of what will be possible in the future.

Compost-fuelled transport

With an ever increasing demand for cars run on renewable energy, it’s not surprising that the range of alternative fuels is growing.
Biomass fuels can be made from animal waste or plants.  Manure, woodchips and crop waste products can all be converted to biomass fuel.  However, these waste products can’t be used as fuel until they’ve been processed. First, the waste has to be mixed with bacteria to make it decompose. This process releases methane, otherwise known as natural gas or biogas.  There are already biogas plants in their thousands in China and India, and countries in Europe are following suit.
Biogas is considered as renewable as there is always more animal waste and plant waste being produced. In Sweden, biogas is big news. The country intends to become carbon free by 2050 and at the moment 25% of all Sweden’s energy comes from biomass sources.  Many buses are powered by biogas, and there are even trains that run on it. Company Svensk Biogas invested one million euros in developing a biogas train, the world’s first.  A 24m long standard diesel train was converted by replacing the diesel engines with two biogas bus engines and gas storage cyclinders to store the biogas fuel. The train runs a 75 mile track between the cities of Linkoeping and Vaestervik, can travel up to 400miles before refuelling and reaches up to 80mph.
In the UK, however, you won’t find many family cars running on biogas, although it is already possible to convert any petrol or diesel engine to run on it, including 4×4 cars and trucks. Biogas hasn’t caught the UK public’s imagination in the same way as hybrids or electric vehicles have as an alternative, greener way to drive just yet.

Hydrogen cars – the cars of the future

Hailed as the cleanest alternative fuel, hydrogen only emits water and is viewed as the fuel of the future. In 2008, Honda became the first company to manufacture a hydrogen production car, announcing the production of 200 FCX Clarity cars, which would be leased, rather than sold, to customers. The FCX Clarity was based on Honda’s first generation hydrogen fuel cell car – the FCX concept car, of which 34 were produced.
Actress Jamie Lee Curtis was one of the first customers to take delivery of an FCX Clarity.  In fact the first five cars were leased to Californian customers; probably because it is the easiest place to find hydrogen fuelling stations in the world.
The lack of fuelling stations for hydrogen vehicles is seen as the biggest obstacle to them becoming more commonplace.  Critics also dispute claims that hydrogen is emission-free, as hydrogen itself is produced through the burning of fossil fuels.
Other alternative fuels, including LPG and biofuel are easier to find than hydrogen, but undoubtedly the simplest way to be an eco-friendly driver at the moment is to drive a hybrid.
A hybrid car runs on a combination of a small petrol or diesel engine and an electric motor.  You can refuel at any normal petrol station and the electric motor recharges itself through a system called regenerative braking – where excess kinetic energy is stored for later use.  Although hybrids still produce some CO2 emissions as petrol is used, these are far lower than with a conventional car.
And as technology has advanced, hybrid batteries have become smaller and lighter. This leaves more room on board for better seat and boot space, so there are now a number of hybrid family cars as manufacturers answer the market demand for a hybrid that suits every kind of driver.

Running a car on wine

Can you run low emission cars on wine? Of course you can’t, so save that Sauvignon Blanc for the dinner table.But the idea isn’t quite as far-fetched as it may sound.For example, when Aston Martin learned that Prince Charles wanted to run his Aston Martin DB5 on bio-ethanol, they contacted the UK company, Green Fuels, for help.

The company promptly bought 8,000 litres of white wine from a West Country vineyard for just a penny a litre, and distilled it.And voila! The prince had his bio-ethanol fuel to run the DB5.Of course turning wine into car fuel all depends on distillation. By boiling off the wine’s c.11% alcohol, and by then removing any water in that distillation, you can produce 99.8% pure ethanol.

You then have perfectly viable green fuel; “green” in the sense that the fuel is renewable.Any alcoholic liquid can be distilled to produce fuel. The only waste is fruit juice, and even that can be used to produce biogas for electricity.

And any car can be converted to run on ethanol-based fuel. But that doesn’t mean we should all be setting up illegal “Dukes of Hazzard” stills in our garages because you need a huge amount of wine of produce a relatively small amount of fuel.

But it doesn’t need to be anything approaching “good” wine; it simply needs to have fermented, so any old rubbish will do!
The best way to produce ethanol on sufficient scale is to brew a “beer” of sorts and then to distill the ethanol out. Just don’t try it at home as it’s incredibly flammable.Instead, if you’re looking to go green and maximize your fuel efficiency, simply buy a hybrid car. It’s a lot easier and it’s a bit greener.

The UKs first hydrogen filling station

?The UK’s first commercial hydrogen filling station will open in Swindon in September. There are very few hydrogen cars on the UK roads at the moment, which makes sense as there isn’t anywhere to refuel. It is hoped that the Swindon filling station will be the first of a network across the nation.

The filling station will be installed and maintained by BOC, the industrial gases supplier. The company is also one of the project partners of the Hydrogen Highway Initiative. The partnership has been set up to promote alternative fuel technologies and the construction of hydrogen filling stations across the south west.

The South West England Regional Development Agency awarded a £250,000 grant to Forward Swindon, Swindon Borough Council’s regeneration body, to build the hydrogen fuel station at Honda’s South Marston plant.

Honda is the manufacturer of the world’s first commercially available hydrogen car,the FCX Clarity. It is hoped that the installation of this hydrogen filling station may encourage Honda to research and develop new hydrogen cars in Swindon. At the moment all of Honda’s hydrogen cars are manufactured in Japan.

Although there are very few hydrogen cars in the UK today, they are seen as the future of driving as they are environmentally friendly and low on emissions. Other low emission cars leading the fight against carbon dioxide emissions include hybrids and electric vehicles. In the UK, 21% of greenhouse gases emissions are caused through transport. Hybrid cars produce lower emissions than conventional cars as they are powered by a petrol or diesel engine assisted by an electric motor. During acceleration, the motor assists the engine, resulting in less burning of fuel, and therefore fewer CO2 emissions. It may be a while before we have a national network of hydrogen filling stations, but drivers could already be lowering emissions by driving hybrids and electric cars.
