Diesel-Hybrids Start Selling

Volvo has announced the V60 is now for sale and is pushing new promotional videos like this one that emphasize safety and low long-term costs — visit fuel stations just once a month. Only 40 views so far:

Peugeot also has announced a diesel-hybrid 508 RXH sports wagon (in brown, of course).

508 RXH

Marketed in France in 2011, and then the rest of Europe by the end of the year, it appears to be based on the diesel-hybrid technology developed for racing.

Peugeot’s diesel-hybrid version of its 908 sportscar underwent its first track test at Estoril, completing more than 300km in the hands of Nicolas Minassian, Stephane Sarrazin and Alexander Wurz.

The barriers to adoption of this far superior technology are price and availability. But if consumers factor in the huge time saving from visiting a gas station half as often or less…the cost concern evaporates. If they are sold in America the only question that remains will be whether they can build cars fast enough (pun not intended) to meet demand.

Steam Car for Sale

An auction tomorrow will be for a four-seater steam “quadricycle” with a range of 20 miles on 40 gallons of water — the 1884 De Dion Bouton Et Trepardoux Dos-A-Dos Steam Runabout.

De Dion’s little quadricycle can claim to be the first family car, despite its arcane power source. What makes it different from road-going locomotives dating back to Cugnot’s 1770 tractor is its sophisticated boiler, which can be steamed in 45 minutes. It is also compact at only nine feet long and relatively light at 2,100 pounds. But, it has four wheels, seats four, and can be driven by one person — like a modern car.

Steam Car

One of the oldest still functioning vehicles, and a promising early design, but it is said to have been expensive even back in 1884.

By 1889 you could buy a tricycle for 2,800 francs ($540) and a quadricycle for 4,400 francs ($850).

Those prices were certainly out of the reach for the average enthusiast, when a French laborer might make five francs a day, and sales were confined to the very rich.

Hmmm, 5 francs a day x 365 days = 1825 francs. So a tricycle would be double an annual salary. An American laborer might make $120 a day x 365 days = $43,800. So a car today, in relative terms, is about half the price of one “confined to the very rich” in the 1890s? That’s like saying a $60,000 car today is confined to the very rich. Am I missing something?

Price was surely a factor but it seems the real reason for demise was the allure of gasoline.

By 1893 gasoline was the up-and-coming power source, and steam devotee Trepardoux left the firm and presumably went back to toys. A celebrated duelist and ladies’ man, De Dion was keen on animal welfare and made a few large steam trucks in an effort to free horses from hauling heavy carts, and then he and Bouton focused on gasoline automobiles. They patented their transmission in 1895 and dominated the early years of the 20th century, with De Dion engines powering some of the first great marques, like Renault, Pierce-Arrow and Delage.

Water-bottles as light source

There seems to be some kind of buzz around a story on water-bottles as a light source. The past couple days it’s been mentioned numerous times. The story I heard first was from Brazil. This video was posted May, 2008:

Then in 2009 or 2010 I heard about it in Africa. Apparently the new story is from Indonesia, in an advertisement.

It’s a great story of finding efficiencies on several levels. It reminds me of the large tubes of water in some high-end solar homes that connect to the roof and not only light a room but heat it as well. They are more than just sun tunnels but actual vertical columns of water that run floor to ceiling in a room and radiate energy. Of course I can’t find any images of one right now…need some buzz to get them to appear again. Maybe the water-bottles will help.

LSE Report on Cycling Benefits

As I mentioned a few months ago, I attended the London School of Economics in the early 1990s and commuted every day by bicycle from outside of Greenwich to the Strand, about 10 miles each way.

No matter rain or shine, light or dark, I was pushing the pedals like a Victorian only 100 years late to the party. It was great fun although I was almost always the only cyclist on the road. In fact, come to think of it, I never saw another cyclist on the road back then, not even as I flew along with traffic above the banks of the Thames.

Crossing Tower Bridge in the rain at night on smooth metal grates in-between thundering lorries and at their speed is just one of the risks I learned to manage with skill and experience.

However, after six months I had to cut back and eventually stop riding due to the effects of harsh pollution on my lungs. The unregulated diesel fumes and particulates caused permanent damage and created the feeling of almost constant illness — a risk for which I tried but was unable to find any workaround. My GP literally told me to stop riding so far and so often because the London air was poisonous.

It is therefore amusing to me to read the brand new LSE report on the benefits of cycling that claims it can reduce illness.

Dr Alexander Grous of LSE’s Department of Management calculated a “Gross Cycling Product” by taking into account factors such as bicycle manufacturing, cycle and accessory retail and cycle related employment
[…]

  • Cycling to work is associated with less all-cause sickness absence. Mean absenteeism in cyclists is significantly lower than in non-cyclists with a significant relationship between frequent cycling and absenteeism, with regular cyclists taking 7.4 sick days per annum, compared to 8.7 sick days for non-cyclists
  • Frequent cyclists save the economy £128 million in absenteeism per year, projected to save a further £1.6 billion in absenteeism over the next 10 years
  • Compared with the rest of Europe, the UK has the highest number of sick days taken each year, with 225 million days estimated to have been taken in 2010 at a cost of £17 billion. This equates to around £600 per employee per annum, and an average of 7.7 days per person

I get the impression the report writers are not long-term cyclists as they leave out numerous other benefits. They definitely don’t read this blog. Even worse than the omission of the effects of pollution on cyclists is the omission of cycling benefits as a zero-emission transportation option. They also omit the benefits of social networking, as I’ve written about before in regard to an English propaganda movie. And the report omits the resilience of cyclists to natural disasters, as documented after the Japanese Tsunami; bicycles work without fuel supplies, fair roads, electric grids…they are the most effective form of transportation for national security and resilience to infrastructure failure.

It’s great to see cycling catch on in England but perhaps the greatest point of all is that England was full of cyclists after WWII for the reasons I mention above. Their decision to follow the US model of the automobile was a huge mistake if you run the numbers.

Thus, I find the LSE report a great start but embarrassingly weak analysis. Can they really directly attribute better health to cycling or is it just a correlation related to an overall lifestyle or even culture (e.g people who buy bikes already are healthy)? I would have added a long list of direct health and security benefits to the LSE report from cycling (e.g. zero emissions) to the gross product as well as call out the massive losses and costs since the decline of the last English cycling boom in the 1940s. Finally, I might even have tried to explain why cycling fell out of style.
