Why does my “Spidey Sense” activate every time I hear something about Alta? Something going on there…
The program will simply be called “Bike Share Toronto” and will be operated daily by Alta Bicycle Share , a Portland, Oregon-based company operating bike share systems in New York, Chicago, Boston and Melbourne, Australia.
The new logo will look almost identical to Toronto Parking logos except with a bike instead of a green P, said Marie Casista, vice-president of real estate, development and marketing for TPA.
“(The name) really represents what it is,” Casista said, “and what we’re doing.”
The beleaguered urban cycling program, which started in 2011, has struggled financially, telling the city last year it could no longer make payments on a $3.9-million city loan.
In December, Bixi’s creator Quebec-based Public Bike System Company and the city came to a deal to transfer all Toronto assets , with TPA set to run the program as of April 1. In January, the Public Bike System Company filed for bankruptcy protection.

Citibike, that is.
A new study out of NYU: http://wagner.nyu.edu/rudincenter/wp-content/uploads/2014/03/CitiBikeTakesNewYork_.pdf
Citi Bike has become a vital element of the city’s transportation network, providing a new flexible mode for many New Yorkers. Trips that were once 20-minute walks are now 5-minute bike rides, and places previously inacces- sible by public transit are now linked to the network.
In its first six months of operation, Citi Bike riders took more than 6 million trips, and by early January, nearly 100,000 riders spent $95 to become annual members.
Bikeshare proven now to be among the safest forms of transport.

Somebody tell me what to think about this.
Bixi owes the city $31.6 million on a $37-million city loan. Montreal also guaranteed a line of credit on which Bixi owes $6.4 million.That means Montreal taxpayers could be stuck with a $38-million bill, though the city hopes a sale of the international part of the business will cut that amount.Bixi also owes its suppliers $9 million.In total, then, Bixis total debt is at least $47 million.Bixi is also embroiled in multimillion-dollar lawsuits with a former software supplier.

Attention news reporters, editors, producers and quacking heads: The US burns about 18.5 million barrels per day, and produces 7.7.
18.5 – 7.7 is 10.8.
These numbers are from the freakin EIA itself: http://www.eia.gov/petroleum/supply/weekly/pdf/table1.pdf
No wonder the Koreans are kicking our tails in math. We get reports like this, all over the internet and on NPR:
In October, for the first time since February 1995, the U.S. produced more crude oil than it imported, the Energy Information Administration said this week.
EIA, the Energy Department’s nonpartisan statistical arm, said U.S. crude oil production averaged 7.7 million barrels per day in October while 7.6 million barrels per day were imported.
Even if that were true, all it would mean is that we still have to import half the oil we burn. But we’re not there yet, and may never be (again).

Via MIT. Looking at 2005:
… Total combustion emissions in the U.S. account for about 200,000 (90% CI: 90,000–362,000) premature deaths per year in the U.S. due to changes in PM2.5 concentrations, and about 10,000 (90% CI: −1000 to 21,000) deaths due to changes in ozone concentrations. The largest contributors for both pollutant-related mortalities are road transportation, causing ∼53,000 (90% CI: 24,000–95,000) PM2.5-related deaths and ∼5000 (90% CI: −900 to 11,000) ozone-related early deaths per year, and power generation, causing ∼52,000 (90% CI: 23,000–94,000) PM2.5-related and ∼2000 (90% CI: −300 to 4000) ozone-related premature mortalities per year. Industrial emissions contribute to ∼41,000 (90% CI: 18,000–74,000) early deaths from PM2.5 and ∼2000 (90% CI: 0–4000) early deaths from ozone. The results are indicative of the extent to which policy measures could be undertaken in order to mitigate the impact of specific emissions from different sectors — in particular black carbon emissions from road transportation and sulfur dioxide emissions from power generation.

Blending butane into gasoline is why gas prices fall in the fall, according to Robert Rapier. RVP = Reid vapor pressure, the higher the RVP the faster the evaporation. EPA sets limits on RVP of gasoline which are more stringent in summer months than in winter, allowing the increased blending of cheap, yet highly evaporative (word?) butane:
Butane has an RVP of 52 psi, which means pure butane is a gas at normal pressures and temperatures. But butane can be blended into gasoline, and its fractional contribution to the blend roughly determines its fractional contribution to the overall vapor pressure of the mixture. As long as the vapor pressure of the total blend does not exceed normal atmospheric pressure (again, ~14.7 psi) then butane can exist as a liquid component in a gasoline blend.
But with a vapor pressure as high as 52 psi, butane can’t make a large contribution to summer blends where the vapor pressure limit is 7.8 psi. For example, if a gasoline blend contained 10 percent butane, butane’s contribution to the vapor pressure limit is already 5.2 psi and you would still have 90 percent of the blend to go. It isn’t feasible to blend much butane into gasoline when the vapor pressure requirement is low. But when the limit increases by 5 or 7 psi, it becomes feasible to blend large quantities of butane.
Why do we care about blending butane anyway? Because it is abundant and cheap. Butane can routinely trade at a $1/gallon discount to crude oil or gasoline. Butane is a byproduct of oil refining, but is also a component of natural gas liquids (NGLs), which are condensed out during natural gas production. Given the huge expansion of natural gas production in the US, it should come as no surprise that NGL production is also on the rise.

Just like everywhere else…
DENVER – A new report from the Colorado Public Interest Research Foundations shows Coloradans have cut their per-person driving miles by 11.4 percent since 2005.
Since 2005. But is it headed back up compared to last year?
