A review of the Canon
9900 large format printer. As for the cost of ink here is some info
Speaking with Canon,
I found the
Of course, every
image is different, but in Canon's testing, the company used the ISO
Standard #5 image to estimate inktank usage. (This image provides a
fair and accurate ratio of colors to approximate the average digital
photograph.) Here are the results, according to Canon:
Cyan: 1100 pages
Yellow: 540 pages
Photo Cyan: 380
Photo Magenta: 280 pages
Green: 2300 pages
new red and
green tanks, obviously, are used far less often than the others because
they're primarily used for accent work. They're the last tanks you'd
have to replace.

Based on CDN$20 per cartridge (current pricing seems to be in the $15 -
$19 range) this would work out as $0.24 per print. What the poster did
not mention was what the print size was... in a follow up it was said
to be 8x10 on standard printer settings, using Canon Photo Paper Pro
Here is some more information:
I purchased the i9900
about 6 weeks ago
to replace my S9000. The
S9000 is no slouch and a top rated printer from 2 years ago but i9900
is much better. I now shoot with a Canon 10D and Canon L lenses even
though I have thousands of transparencies to scan on a Canon FS4000US
film scanner. The 10D was purchased just prior to a trip to Rome where
I shot about 1000 images.
I just finished
assembling 170 of
the best Rome images into an album using Canon PhotoRecord software
that comes with most Canon digital products. I printed the album on
both Epson dual-sided matte paper and Pictorico dual-sided semi-gloss
paper. The results are amazing. Both papers work extremely well with
the i9900 although they each have their own subtle tinting difference.
This can be corrected easily with color adjustment through the printer
driver. Printing the entire album on the dualsided 8.5 x 11 stock (68
pages total) used no more than half of some of the ink cartridges and
almost none of the red and green. People who have viewed the album are
stunned and amazed with the quality and can't believe it came from an
inkjet printer. The color punch and tone is incredible and the level of
detail and resolution equals or exceeds wet chemistry printing. If you
want to see dots you'll need at least a 4X loupe and there is
absolutely no banding.
It is a mistake to
not consider this
printer because of the limited selection of Canon papers. Epson papers
work extremely well on the Canon printers as do Pictorico, Mitsubishi
and Konica. These are the only papers I've had the opportunity to try.
Needless to say, I am very happy
I bought this printer.

which is pretty impressive).

 The world's largest Solar
Tower may be built in Australia, will it also be destroyed a short
time later by the world's largest tornado? In 2010 plans for another solar updraft tower to be built in Arizona appeared, this called for a 2400 foot tower fed by a 4 square mile green house to produce 200MW. The stated power does not seem reasonable for such a large project, as 4 square miles is just over 10 square km, and each square km has about 1GW of solar radiation (1000W/m2 x 1000m x 1000m = 1GW), so 200MW/10GW = 0.02 or only a 2% collection efficiency which seems rather low.

Wind Power in Cold Stores, this is really a case of intelligent
load averaging, and thus, swapping some conventional power requirements
for wind generated power. For one to really make the claim of "storing
power" one should be able to place energy into the storage device and
then return some of that energy back to its original form for later
use. That said, this is a good example of "low-hanging fruit", there
are probably plenty of power users that could be tailored to make use
of alternative power sources when those are abundant (for example
commercial green houses, swimming pool heating, ice rink cooling...).
solar cells (DSSC) are being developed at Ohio State, these promise
to produce power for about 1/4 the cost of conventional cells.

 Here's an interesting twist, for $199 you can buy a mini-ITX motherboard, RAM and disk drive from Walmart, what you do is purchase their Everex green PC, and then gut it for the mini-ITX motherboard that it contains. This gets discussed here on Slashdot. A review of this PC along with more discussion on Slashdot. PCMag didn't find much to like about this system.

 Sustainable Websites is a web hosting service that uses 100% green sourced power.  Hyperion plans to build a factory to manufacture small nuclear power modules (they call them batteries). These would be hot tub sized devices capable of producing about 27MW. These have a uranium hydride core surrounded by a hydrogen atmosphere and need to be connected to a steam powered generator. It is supposed to be self regulating with no moving parts. They now claim to have a backlog of $2G worth of orders for more than 100 devices (discussed on Slashdot) and one potential application is in providing power to tar sands oil extraction (which could also reduce green house gas emissions by replacing the natural gas that is used for this today).  Shuttle is going to produce the KPC a low end small form factor box intended for use with Linux, complete at $199 and barebones at $99. Discussed here on Slashdot. There is some more information on this here, the complete system will have a Celeron processor, a 945GC chipset, 512MB of RAM and a small shard drive. From this it sounds like it might be using something like the Intel D201GLY2 mini-ITX form factor motherboard. Tom's Hardware has a look at this here. Some more coverage of this on The Tech Report. The Shuttle web site on the KPC, looks like it has gigabit ethernet and 5.1 audio but no DVI monitor port - just VGA. The KPC is finally ready to star shipping, Engadget reports it at $299 for the full unit (which originally was supposed to be $199), the Shuttle site does mention a $199 version but does not give any details yet. A review of this can be found here. Building a small home server with a KPC system.

 The Linutop 2 mini PC is another entry into the small Linux based green computing platform - though its more expensive than some of the competition like the Koolu.  Green Freedom is a project to extract CO2 from the air and turn it back into fuel. They don't say where they are getting the energy from that will be needed to turn the CO2 (along with water) back into hydrocarbons, but as their press release is liberally sprinkled with the word "nuclear" and this is a team that is headed by Los Alamos National Laboratory it's a safe bet they are planning to use electricity from nuclear power plants - so this is really no different from the typical "hydrogen economy" babble.  Ars Technica looks at building a green PC, discussed here on Slashdot. They build a lower power (say under 150W) box for game playing and then try to build an extreme green box which uses something in the range of 20-30W. On the extreme box they went overboard on the hard drive and used a 32GB SSD unit which cost $725, they would have done better to have selected a 2.5 inch laptop drive for about $100 (which would have used almost the same power) or found a way to use a 1.8 inch drive (or the kind intended for PMP devices), or use a 16GB CF card mounted in an IDE adapter (they talk about doing this later).  Battery adapters that allow one to use a AA sized battery in a
device that only takes C
cell or D
cell sized batteries. American Science and Surplus also has a
set. Here is one that takes two AA cells and makes them into a D-cell.

 The Triac from Green Vehicles will launch in July - finally an affordable electric car.  Green Plug is an attempt to create a universal charging standard for electronic devices. They have signed up Westinghouse as the first potential producer of products using this. Slashdot's coverage of this has a good discussion of the limitations of doing this sort of thing using USB (including that USB devices must negotiate for more than 100mA to a maximum of 500mA). After a year this universal power adapter initiative is struggling for support.  The Green Machine from ElectraTherm converts waste heat (for example 200F water) into electricity. With a current minimum size of 30KW its a lot larger than a typical home could use, but if they were to produce a smaller module in the 1-5KW range then it is conceivable that one could use conventional solar hot water collector panels to supply the "waste" heat and maybe this would be less expensive than a photo-voltaic solar system. They are claiming a 30KW output from 200F liquid at an input flow rate of 100 gallons per minute, so a smaller module (say 3KW) might have a 10 gpm flow rate which sounds plausible.  An almost fully enclosed electric motorcycle, it won't get you a date but it might keep the rain off. A recumbent seating design would look a lot neater.  Texas wants to blow away all other states in the development of wind power. Slashdot discusses the new green and windy outlook of Texas.
 Managing Meetings talks about using red, yellow and green cards to manage the flow of questions from the floor during a meeting.  Chrysler is starting to get serious about producing some electric vehicles, maybe we'll actually see something by late 2010.  VirtualBox is a machine virtualization package, which is free for personal use (and available for commercial use too). With it you can install multiple guest machines onto a host machine and run them at the same time. So if you are running Windows XP and want to play with Linux (or even Windows 3.1!) you can now have some fun. It gets some coverage here and here. Another short note from a satisfied user.  Slashdot discusses Kleiner Perkins, a venture capital investment firm that has been investing in a number of green-technology companies.   The market melt down of fall 2008 could have been caused by "bad data" being fed into risk calculation programs. More on this as Alan Greenspan testifies about his role in this.  Western Digital has won the race to deliver the first 2TB drive.  The KanaMicro digital audio player is packaged like a USB thumb drive, you really can't get an MP3 player much smaller than this.   The GreenWheel is a replacement hub assembly for bicycle wheels that contains an electric motor and batteries. This allows just about any bicycle wheel to be converted into an electric drive system. It claims to have a range of up to about 25 miles (which should be more than enough for most city use). Hopefully they have designed this so that the guts can be easily accessed in case service (i.e. battery replacement) is needed, otherwise a design that does not integrate the battery would be far superior. One advantage of this approach is that you could put two of these on a single bicycle for two wheel drive, which might be useful in winter cycling.  Apparently methane trapping hydrate formations will absorb CO2 and the CO2 will replace the methane allowing the methane to be extracted.

Dell has made one of its parking lots "green" by installing solar panels that also act as sun shields for the cars parked below. There is a lot of space in parking lots around the world, lets hope others follow suit.  An article on handling out-of-memory conditions in C with some examples of different approaches from Glib, SQLite, Git, lighttpd and Redis.  Why is C++ so bad?  In the past technology has often advanced to address military needs (the space program is probably the best example of this). Now the US has figured out that fuel cells could be a better way to power UAVs for long missions (using 550W hydrogen cells) perhaps we'll see this technology advance faster. A hybrid car that combines a medium sized fuel cell (perhaps in the 10KW range) with a battery pack might be a better alternative to the current internal combustion hybrids.  If the supervolcano in Yellowstone park ever blows we're not going to have to worry about green house gasses.  The US military has been testing a trash to fuel system built by Green Power Inc that sounds rather promising. Green Power has been given the green light to build a commercial trash-to-gas plant in Washington.  How Fisher-Yates shuffling works.   A team of students at Imperial College in London have built an electric car with a 248 mile range and are planning to take it for a spin on a 15,000 mile trek down the Pan American Highway (and it sounds like a TV show may document the adventure too).
