Coffee: it’s every workaholic’s go-to beverage and, astoundingly, perfect for manufacturing sportswear. Nowadays, it isn’t just perfect for a pick-me-up — it’s potentially fueling London’s signature double-decker buses.
“Instead of sending a tonne of waste coffee grounds to landfill where it degrades and releases methane and CO2, we collect it, recycle it and turn it into a renewable fuel which is then used to replace further conventional fuels – so it’s a double saving”, [said] Bio-bean founder Arthur Kay.
Among the heaviest Americano consumers, Londoners contribute up to 200,000 tons of coffee waste annually. To make the most out of discarded grounds, Bio-bean is extracting 6,000 liters of oil to mix into fuel. The final blend is of 20% biofuel, which will also help to reduce carbon emissions.
“We’re not saying that it’s going to totally replace fossil fuels overnight,” Kay said.
“The amount of diesel produced globally is always going to be more than the amount of coffee.”
Considering London buses run nearly 2 billion trips a year, Bio-bean’s initiative could encourage alternative energy use. Perhaps a beer fuel may even be in talks.
With a rising number of electric buses and taxis headed for the streets, roads are having to undergo adjustments, too. Los Angeles is home to an excess of both trucks and smog. To revamp the deadly duo into something more eco-friendly, Siemens has installed its first electric highway where trucks can charge on-the-go.
“To have the road electrified and have these heavy trucks electrified is just far more efficient from the perspective that you don’t waste fuel, you save energy because the electric motor is far more efficient than the gas motor, and you have no emissions at all,” says Andreas Thon, the head of turnkey projects and electrification in North America.
The trucks are rigged onto overhead wires that run the entire length of the highway. The trucks themselves are cost-efficient, requiring significantly less maintenance than diesel motors. The highway also alleviates battery problems, as they don’t generate enough energy for heavy loads.
Thon says, “With this technology, you permanently feed energy into the truck.”
Siemens also hopes to install charging technology beneath road surfaces — but that will have to wait. After all, it does require a lot more science and a lot more money.
It’s been a year of firsts for the railway system — from going solar to launching its fastest model. Pushing its limits even further, China is test-driving its Autonomous Rail Rapid Transit system, which is fully electric and trackless.
ART bears the physical appearance of a train but it doesn’t rely on following a track. Instead, it follows a virtual route using an electric powertrain and tires. It’s expected to function much like an urban train or a tram, but since there’s no investment cost in laying down rails, it should be much cheaper to implement.
The train can only travel 15 kilometers at a time, but can fully recharge in just 10 minutes. Environmentalists will likely tip their hats off to the new system — it’s entirely emissions free! Smoggy China could surely use more sustainable public transport alternatives. Thankfully, its government has been taking other measures to ensure that its locals don’t further experience pollution-caused health issues.
40 percent of China’s factories have been shut down, and authorities are reportedly working on a timetable to end the sale of gas- and diesel-powered cars.
A round of applause for China — sounds fresh!
The steady rise of electric vehicles will soon leave petrol and diesel cars in the dust. BMW is launching electric buses all over Europe, while the London Taxi Company is replacing old cabs. A few months later, the U.K. remains on top of the eco-ladder, with Oxford planning to eliminate non-electric vehicles.
The scheme aims to cut levels of nitrogen dioxide, the majority of which comes from traffic fumes, by three-quarters.
To give distributors leeway, Oxford will be imposing the ban in 2020, increasing the affected zone by 2035. We all know electric vehicles aren’t the most affordable, so locals may have to do some walking. The plan is projected to cost £7 million, but the city council deems the shift will be well worth it.
Oxford city councillor John Tanner said a “step change” is urgently needed as toxic air pollution is “damaging the health” of residents.
It’s a bold move, Oxford, but hopefully a successful one.
Developers have been doing everything to ensure the eco-friendliness of future vehicles. They are engineering sustainable commutes and even air-purifying bicycles. However, no one has gone as far as scientist Peter Mooij, whose brainchild is a wooden motorcycle powered by algae.
The single-sided swingarm is made with birch and oak, with an oiled cork/oak damper and a cork insert to provide a compression zone in the spring. The rear single-sided swingarm is made from solid oak, with some cork between the arm and the frame.
A fully functional wooden vehicle? I thought those were called wagons. As for the bike’s eco-fuel, microalgae produce oil, which is perfect for a diesel engine.
“Algae oil has some great advantages. Algae do photosynthesis and by this process algae convert CO2 from the atmosphere into oil. If this oil is burnt in Rits’ motorcycle CO2 is emitted, but the amount of CO2 emitted exactly equals the amount of CO2 the algae took up from the atmosphere.”
To put it simply, we lose nothing, which is pretty darn practical. Mooij is still working towards an enhanced model of the motorcycle. In the meantime, an extensive Google search on microalgae may be on my agenda.
