$10 to Ride Across Canada

A trip across Canada in 30 days for less than $10 in total power cost (watt-hours) is explained by Justin Lemire-Elmore in the following video. He gives four reasons for his summer 2008 journey:

  1. Meet electric bike enthusiasts dispersed across Canada
  2. Examine feasibility of touring by electric motor
  3. Develop products such as LED lights, 100-140 km range battery, and on-the-fly recharge
  4. Prove to the world the low-cost efficiency of electric bicycles

That $10 is actually donated from random 120V stops along the way.

Every building had outlets on the side

He was intercepted just once and asked to pay a dollar, which he declined because his battery only draws $0.06 for a recharge. He spends just $0.86 for the ride from Vancouver to Lake Louise, with a target of 12 watt/hr per km. There is quite a bit of classic hacker behavior such as trip segments starting at 2am and breakfast as the only meal of the day. Fresh fruit stands also are often mentioned, as recharge stops for the rider.

Also notable is the discussion of engineering feats such as odd hand-built bicycles and even tunnels in the Rockies that stand above the road in summertime — built to prevent impact of avalanches.

Electric Car Facts

I hate stories like this one by the Associated Press.

Electric cars are also more limited than their gas-guzzling cousins, running 40 and 120 miles (60 to 200 kilometers) on a charge, while taking anywhere from two to seven hours to fully recharge.

The problem with this? Although the article gives a negative tone with phrases like “more limited” the perfect fit for electric vehicles is the urban and suburban driver who never go more than 120 miles per day and are stationary for at least two hours a day. This technology is not meant to replace the fantasy of the open road trip; the one people in the suburbs always talk about but rarely ever act upon. They could rent an exotic non-guzzling turbo-diesel performance vehicle for those days.

Here is another example:

Jay Nagley, the publisher of Clean Green Cars, a British online guide to environmentally friendly vehicles, said the G-Wiz, while ubiquitous, is technically not a car but an “electronic quadricycle.”

He said the G-Wiz had limited appeal outside the British capital, where wealthier residents use it mostly to avoid parking fees and the city’s hefty congestion charge.

“It’s pretty expensive paying seven grand for a four-wheeled motorcycle. You’d be pretty brave to take it outside the city center,” he said.

First of all, seven grand is peanuts for a new high-end motorcycle in London, especially one to carry two passengers and baggage. When you factor in the maintenance and gas consumption of a motorcycle then the G-Wiz doesn’t seem “pretty expensive”. It also is a tiny sum compared with the cost of property in London. Finally, why should an urban vehicle have appeal outside the British capital? That seems to me a lot like saying an airplane doesn’t do very well as a ferry on the Thames. This chicken does not taste like beef. There should be more attention paid to the objectives of new transportation with better efficiency and less noise about the old fantasies, habits and fashions.

Some of the more meaningful things that the article could have mentioned is a reduction in risk that comes from smaller vehicles, lower insurance rates, etc.. It also could have mentioned stats like the average daily distance traveled by American drivers; seems like it is around 50 miles, perfect for a small electric bike with two or four wheels.

American Water Safety History

Every so often I am reminded about the need for safe water. A site called GOOD has put forth a list of disasters related to water in American history. They start with the latest one, a tragic story that has directly impacted the health of soldiers at home:

For years, U.S. health officials have claimed that although the drinking water at North Carolina’s Camp Lejeune is contaminated, it poses no danger to Marines or their families. This April, the government reversed itself, saying that its assessment of the water contained “omissions” and “inaccuracies,” and adding that a million people over the course of three decades may have been exposed to the carcinogen benzene in their water. Fifteen hundred former Lejeune Marines, some of whom are now afflicted with rare lymphomas, have filed lawsuits seeking more than $33 billion. Sadly, Lejeune is just one of the many recent poisoned-water cover-ups in American history. There are others going on all the time. Here are some more of the worst.

A phrase like “some of the worst” is a research cop-out. Inquiring minds want to know what are the worst? Where is the baseline for “worst”. Number of people affected? Area? Length of time? Where is the comprehensive list of disasters? I don’t ask just to be facetious but also because I think it will help put cybersecurity in perspective, especially with regard to SCADA systems.

4 Day Work Week

The Scientific American reports on Environmental and Economic Pluses of the 4-Day Workweek

Local governments in particular have had their eyes on Utah over the last year; the state redefined the workday for more than 17,000 of its employees last August. For those workplaces, there’s no longer a need to turn on the lights, elevators or computers on Fridays—nor do janitors need to clean vacant buildings. Electric bills have dropped even further during the summer, thanks to less air-conditioning: Friday’s midday hours have been replaced by cooler mornings and evenings on Monday through Thursday. As of May, the state had saved $1.8 million.

No word on how this helps security, but clearly happier employees are less likely to become a risk (reduces motive). Although the time in the office is the same, I suspect the shift to longer days and fewer of them is also less risk (potentially reduces opportunity). Just as employees are on the road 20 percent less, they also potentially need authorization 20 percent less. The article does mention that health issues are reduced, surely because commuting and work-family pressures are reduced as well.

“Utah employees actually show decreased health complaints, less stress and fewer sick days,” Wadsworth says, noting previous research finding that fatigue is typically triggered by workdays over 12 hours. Early results from another multicity survey indicate that just 20 percent of respondents said they felt they ate more fast food and only 30 percent said they worked out less. In fact, 30 percent said they exercised more. Anecdotal evidence from Utah also points to an unexpected benefit: increased volunteerism.

That suggests four day work weeks are the limit. No need to get excited about trying the three day model. Another benefit might be more time at brick-and-mortar retail, which could boost the economy as well, and have more people outside for more days potentially reducing street crime.
