The VW diesel scandal has changed opinions.

The VW diesel scandal has changed opinions.


Car sales people may need a new pitch to buyers after this change to government policy. ‘Clean diesel’ is dead.

The Government is reportedly considering a scrappage scheme for diesel cars to improve air quality, reports the Belfast Telegraph.

Drivers should think long and hard before buying a diesel car, the Transport Secretary has said. Chris Grayling suggested motorists should consider buying a low-emission vehicle rather than spending their money on a diesel.

His intervention follows reports the Government is considering a scrappage scheme for diesel cars to improve air quality. The reported scheme would see drivers offered a cash incentive for replacing an old diesel car with a low-emission vehicle.

The predictable war on diesel cars is underway. The days of promoting them as ‘climate-friendly’ are over, in the UK at least. Diesel trucks, vans and buses are overlooked.

London’s air pollution problem is so bad that just five days into 2017 Brixton had already used up its traffic fume allowance for the year, reports iNews.

Brixton has since been overtaken by Knightsbridge as Britain’s most polluted district so far this year. The wealthy west London suburb has exceeded the EU nitrogen dioxide (NO2) limit for a total of 52 hours already this year, nearly three times the legal annual allowance of 18 hours, according to the latest figures from Dr Gary Fuller at King’s College London.

But traffic pollution is by no means confined to these London hotspots.

Electric vehicles still in the foothills

As the author suggests, the wishful thinking of policy makers in the world’s better-off countries shows little sign of turning into success ‘on the ground’ when it comes to electric vehicles. Public concerns about cost, range, battery life, recharging and so on are not going away.

An article in Power Engineering International magazine in 2013 by Penny Hitchin identified progress in the development of electric vehicles, as well as the barriers to progress, writes PEI’s Diarmaid Williams.

Four years later, despite a relative surge in uptake of these vehicles, much of the same barriers remain. It’s anticipated that the evolution of the electric vehicle will transform the nature of electric power, but this evolution is unfolding at a slower rate than perhaps anticipated, or desired given the political expediency to decarbonise.

When Hitchin penned her piece, Charging ahead: EVs and the grid, there were 130,000 electric vehicles in the US. In December 2016 that figure was 542,000, according to Recode website, so there is an incremental rise, even if it’s not as rapid as hoped. The same problems are besetting countries around the world in moving away from fossil fuels and capitalising on the extraordinary progress of renewable power.

It’s a similar situation for cars.

Five million Euros to power a few street lights sounds expensive. What effect traffic has on the panels remains to be seen, but dirt could be an issue.

A solar panel road, claimed to be the world’s first, has opened in France, reports the Daily Mail Online.

The 0.6 miles (1km) stretch of road in the small Normandy village of Tourouvre-au-Perche is paved with 2,880 solar panels, which convert energy from the sun into electricity. It is hoped that the the road could eventually provide enough energy to power the small village’s street lights.

The ‘Wattway’ road features 2,800 sq m (9,186 sq ft) of panels and was showcased today at an inauguration ceremony attended by French minister for Ecology, Sustainable Development and Energy Ségolène Royal.

The road is expected to produce 280 MWh of electricity a year.

Achates engine design

Achates engine design


That’s the sales pitch for an opposed-piston alternative to today’s vehicle engines. No valves, no cylinder head. But will it get off the drawing board? WIRED reporting.

IF YOU POP THE hood on your car and yank out the plastic cover beneath it, you’ll see a beautiful bit of mind-boggling engineering: the internal combustion engine.

Today’s engines harness around 100 explosions of fuel and oxygen each second, generating massive power with minimal emissions. That’s great, but tightening pollution standards around the world mean automobiles must become increasingly efficient.

Electric cars offer one way forward, but they remain expensive and hobbled by range anxiety—the fear, often unfounded, that you’ll end up stranded with a dead battery. Internal combustion isn’t going anywhere anytime soon, with advancements like turbochargers, direct injection, and variable valve timing squeezing more miles from every gallon.

Achates Power in San Diego believes it has a better way: Ditch the design that has dominated engine design for the past 130 years in favor of an idea abandoned in the 1940s and see a 30 percent bump in efficiency.

Too good to be true? If not, what might the future hold for this innovation? Phys.org takes a look.

An Israeli firm says a super-efficient engine it has created could drastically reduce fuel consumption and help power an auto industry revolution as manufacturers search for environmentally sound alternatives.

Industry analysts, however, question the reinvented internal combustion engine’s chances of success at a time when purely electric car technology is advancing and attracting investors.

The invention from Israeli-based Aquarius Engines is currently being discussed by France’s Peugeot, the firm said.

One thing’s for sure – they won’t be adopting the Guardian’s solution of no more runways ever. When one battle ends another will start, as ITV News reports.

The Government will tomorrow make a decision on where a new runway for the south should be built and Heathrow is expected to be the winner.

But it is expected that Gatwick could also be allowed to expand at a later date. The decision will then be subject to consultation ahead of a vote by MP’s in early 2018.

Obama’s Electric Car Fail

Donna Laframboise does the unthinkable and waves one of the US president’s promises – or predictions – under his nose, pointing out its hopeless failure to come true. Trying to get people to limit their travels to 100 miles or so is about as likely to succeed as nailing jelly to the wall.

Big Picture News, Informed Analysis

Only 40% of Obama’s electric cars are on the road. None meet the 150-mile-per gallon standard he promised.

obama_electric_car_promise1

Last year 17.5 million cars, SUVs, and light-weight trucks were sold in America. A mere 115,000 of those (two-thirds of one percent) were electric vehicles. Let’s press the rewind button back to the 2008 presidential campaign trail, in which Barack Obama declared:

we will help states like Michigan build the fuel-efficient cars we need, and we will get one million 150 mile-per-gallon plug-in hybrids on our roads within six years. [bold added]

In March 2009, two months after he became President, Obama delivered a speech at the Southern California Edison Electric Vehicle Technical Center in which he similarly asserted:

we will put one million plug-in hybrid vehicles on America’s roads by 2015.

In these closing months of 2016, it’s reasonable to ask how those green promises worked out. In…

For at least 21 years now, the U.N. and the IPCC have been ringmaster to a troupe of thousands. They perform at massive annual conferences held in exotic locations, serviced by top hotels and airlines, and funded largely, directly or indirectly, by reluctant taxpayers. 

An estimated 45,000 attendees, including 114 from the Australian government, achieved nothing useful at Copenhagen and just more green tape in Paris. Each of these climate-fests is preceded by numerous meetings of bureaucrats drafting and redrafting their wish lists.

Now the U.N. Climateer-in-Chief, Ban Ki-moon, has jetted into the G20 summit in China to claim climate victory over climate skeptics.

Is there no end to this energy-wasting climate tourism? If they believe that the science is settled, no more conferences are needed.

What’s this – business before enviro-correctness? Shocking to some perhaps. Could be fun if Scotland’s air fares undercut England’s by a significant margin. BBC reporting.

Plans to cut and replace air passenger duty (APD) in Scotland have been met with a mixed response. The Scottish government wants to replace APD, with the tax to be reduced by 50% from April 2018 and eventually abolished.

Or they may not. Robotic futures tend not to work out as predicted, but here’s another one, as DW.COM reports.

One likely roadblock is the amount of electricity required to make it feasible. Another one could be public resistance…

By 2025, self-driving cars could lead to a steep decline in fossil fuels – and in personal car ownership. Smart electric vehicles will pick you up, drop you off, and mostly look after themselves. A realistic scenario?

So far there are no scrap metal collectors for space junk, as this Science/AAAS report illustrates.

Humans are messy, and not just here on Earth. Now, you can see all the junk we’ve launched into space for yourself with a data-driven animation created for the United Kingdom’s Royal Society by Stuart Grey, an astronomer at University College London.

It all begins in 1957 when the Soviet Union launches Sputnik, a 58.5-centimeter-wide ball emitting radio pulses. A piece of the rocket that took it into orbit was the very first piece of space junk. The United States launched its own satellite, Explorer 1, the next year.

The train now standing at Platform 1 is waiting for the wind to blow. Is that the future for Dutch railways? Peering through the hype, we may suspect other sources of power will have to be used if or when it’s not windy enough. TechXplore boards the green-tinged bandwagon:

Can the Dutch rail network run on wind? Julian Turner, writing in Railway-technology.com, reported that the Dutch rail network will run entirely on renewable wind energy by 2018.

The UK has an impressively large development budget for its so-far unimpressively small collection of electric cars, as Phys.org reports. Is there any high-tech cure for ‘range anxiety’?

Wireless charging technology that is built into the road, powering electric cars as they move, is to undergo trials on England’s offroads. Announced on Tuesday, the technology will address the need to power up electric and hybrid vehicles on England’s roads. The trials will get under way later this year.

The bad experience with batteries in London’s own-design hybrid buses hasn’t deterred further investment in the technology, reports E&T Magazine.

The first diesel buses converted to hybrid power will run on the streets of London early next year.

London is introducing an ultra low emission zone in 2020, so diesel buses will have to be replaced or converted to hybrid or all electric power.

While the price of fuel is rising, government subsidies are being cut. Vantage Power estimates that switching to hybrid power saves operators around £20,000 per bus per year and said retrofitting can convert four old buses for the price of one new one.

The so-called ‘Boris bus’ or London’s ‘new Routemaster’, hailed as a wonder of green technology, is turning out to be an embarrassment, reports BBC News:

I’m told that at the back of a bus depot, there is a large pile of power batteries that no longer work.

All have been removed from the new bus for London and are a crucial part of the hybrid system.

Drivers say that many buses across London are operating without them in place.

What effect will this have on public perceptions? Might help to consign climate change to the fringes of acceptability as an issue with any luck. The BBC reports:

Protesters disrupted flights at Heathrow Airport by cutting through a fence and chaining themselves together on a runway.

Direct action group Plane Stupid said 13 demonstrators opposed to the airport’s expansion plans got on to the northern runway at 03:30 BST.

The runway was closed for nearly three hours and 13 flights were cancelled.

The British Antarctic Survey has a new research station with a difference, reports the New Scientist:

CONSTANT darkness, bone-chilling temperatures and cut off from the rest of the world. Living in Antarctica isn’t for the faint-hearted – and I should know, I overwintered there a while back. But at least I lived in a base built on rock; it’s quite another matter when your home sits on top of a floating ice shelf. This is Halley VI, the Antarctic’s most futuristic construction so far.
