Fixing a Pentax *iST DL DSLR

Monday Aug 17, 2009

In the wake of the cash for clunkers scam, the planned obsolescence of a few million televisions, and some misguided efforts to prevent electronic devices from being reused or recycled outside of the U.S., the obvious solution when my digital SLR began acting up should've been to pitch it and get another one. I'd already investigated and discovered that a newer model could be purchased for less than it would cost to send mine in for repair. But since I had nothing to lose, I decided to give it a try. I'm happy to report that this minor repair was a success! One less bit of e-waste.

I intend to put more of this kind of content on opensourcemechanic.com so this blog can grow more focused on Sun/OpenSolaris specific issues.

CA$H for Wintel Clunkers and Common $ense

Thursday Aug 06, 2009

According to a CNN money article on the Cash for Clunkers program:

• The trade-in vehicle has to get a combined city and highway fuel economy rating of 18 miles per gallon or less.
• The average fuel economy of new vehicles being purchased under Cash for Clunkers is 25.4 mpg
• The average fuel economy increase from the old vehicle to the new is about 61%.

For this 61% fuel economy improvement in a relative small percentage of the U.S. car fleet, $1 Billion has been spent and another $2 Billion may soon be wasted. There are a number of problems with this program.

• U.S. fuel economy peaked in the late 1980s and vehicles exceeding 25 mpg have existed since AMC's 1959 Rambler, so only those who deliberatly chose the lowest mpg vehicles can avail of the program.
• Those who chose economy cars and other respectably efficient vehicles (Civics, Festivas...) are punished to subsidize those who chose inefficient vehicles (Hummers, Vipers...), in effect it is a regressive tax!
• The real mpg/person savings can be negative, for example when an 18mpg 8 passenger vehicle is replaced with a 25.4 mpg 4 passenger vehicle.
• The program also ignores the fact that it takes energy to crush an old but serviceable car and replace it with a newly built car.

If the Cash For Clunkers program had instead been directed to encourage companies and individuals to junk their Wintel PCs and replace them with Sun Ray thin clients, there is a potential for a 97.5% decrease in energy consumption. So why isn't there a Cash for Clunkers program for desktop personal computers?
