powered house that gets 100% of its energy from solar and does long
term storage of excess energy by storing hydrogen gas (produced from
electrolysis of water) and then using the hydrogen to power fuel cells.
This allows the house to capture excess power in the summer for use in
the winter (when the solar panels do not provide enough power). While
largely funded for research purposes the intent is that others
should be able to repeat this for a price of about US$100,000 (which is
still probably beyond economically justifiable).
Buffalo is making the PC-MV72DX/U2,
which is a video capture and playback device that includes a TV Tuner.
This does not have internal storage, it can be attached to a PC or a
NAS device to make a full-blown PVR.

One professional photographer's idea of what would make a great compact camera.
This is an interesting specification here are some thoughts about it:
- he calls for an APS-C sized sensor, which would be a very
good thing from the noise perspective (but this will make the lens
larger so he accepts a smaller zoom range). The resulting zoom
range of 28-70mm is useful for much photography (especially landscape
type work) but the 70mm end is going to be too short to appeal to a lot
of people. I have found that with the 28-210mm range of my Minolta A2 I
rarely need more zoom, and in the times I do I'm looking at something
so far away that I'd probably need a 500 or 1000mm lens to get a decent
photo anyway. Back in the late 70s and 80s when I did 35mm film
photography I typically found 135mm adequate and considered the 200mm
telephoto "exotic". The Minolta A2's lens is about the same
physical size as may 35mm camera's 50mm lens, largely because of the
film-size issue, the A2 has a smaller sensor that APS-C (but its larger
than somthing like the Canon G series), and I'm sure today that a
sensor of this size could be made with low noise up to at least
- I don't see much need for additional screw in optics (i.e
a 2x converter) as they tend to be so bulky (as big as this camera!) that
you're not going to be carrying them with you - it is better to make
the basic lens a bit bigger to get a bit more zoom range (using a
folded optical path you probably could fit a 28-150 or even 200 lens
with a bigger sensor in a pocket size camera).
- I agree with the need for standard screw-in filters, I
often make good use of a polarizing filter.
- I find his specification of only having a live-view LCD
and no optical view finder built in refreshing, he's missing two points
though, first you need the view finder to be articulated, both so you
can look down when shooting waist level and so you can look up at the
camera for an overhead shot; the second point is for you to be able to
do manual focusing the Minolta A2 shows you need at least a 900K pixel
resolution (and even then that's often not enough).
- The internal buffer should hold 10 shots in RAW, and in
motor drive mode it should pre-capture some frames (i.e. once the focus
is locked it should capture frames even before you finish pressing the
button) and save a number of these at the start of each sequence.
- The battery pack should be standard AA size (not another
custom lithium pack that needs a custom charger), using two NiMH cells
normally and regular AA cells if you get caught in a tight spot, I
wouldn't mind only getting 200-300 shots out of a single pair of NiMH
cells as they are so cheap you can always carry a few sets with you to
do something big.
- By super-heating cobalt ferrite to 2600F one can force it to release trapped oxygen, then by cooling it to 2000F it will capture an oxygen molecule from CO2 or steam. This can be used to make CO (carbon monoxide, which can be used as an organic chemistry building block) or hydrogen gas. This is being proposed as a way of reducing CO2 emissions from power plants (discussed here on Slashdot) by obtaining the necessary power to heat the cobalt ferrite from concentrated sunlight. However, much of the captured energy is not needed for this process due to the high value of the lower process temperature (i.e. 2000F) so the ultimate efficiency will be quite low and one probably would be better just using the solar power to generate steam to drive turbines to generate electricity and by doing so just reduce the amount of fossil fuel that must be burnt in the first place. 
- A new approach to thermoelectric conversion using rough silicon nanowires could raise the efficiency of these devices to useful levels. Referred to here and discussed here. While I don't see much merit in using body heat to recharge things like cell phones as there are better ways to do this (like small solar panels), if this technology could give you something like a 5% efficiency then it could offer a new approach to small scale solar power for the home, but allowing systems that capture solar energy and store it as hot water to be used to provide useful electrical power in addition to space and water heating.

some handy addons for Windows desktops. They have a nice demo-maker called
HyperCam that captures what you are doing on your screen and saves it as an AVI
file, I tried their demo and it worked first time on both Windows NT
4.0 and Windows 2000 (which is more than I can say for the other three
packages I tried - two of which did not even install successfully).

- An article that is critical (and justly so) about recent changes to the SSL certificate warnings in Firefox 3. This is discussed here on Slashdot. The approach I would favor would be to have two indicators: one to indicate that you are using SSL encryption to protect the communications with the web server and the second to indicate that you are talking to an authenticated web site. In this way if one was talking to a self-signed site (or one that is signed by an unrecognized authority) only the encrypted status would be shown. Of course this makes things a bit more complicated for the user, but it would be less intrusive than the current solution. More criticism of it here and here (with good screen captures) and further discussion on Slashdot here. 
- The nanoantenna is small enough to capture infrared radiation and turn it into electricity. 
- A rather odd looking ball-shaped wind turbine from Sweden. This article has a better view of the blade shape. 
- XDepth 48 is an attempt at moving JPEGs to 16 bits per color (i.e. 48 bits per pixel). This would be a very good thing as it would allow camera manufacturers to build systems to capture a greater dynamic range (without having to resort to RAW formats).  
- Windspire's vertical axis turbine for the housing market claims to be able to provide about have the average household's electric power (though the cited figure of 2000kWh annually seems rather low). 
- The GoPro HD Hero Naked is a 1080P HD camera capable of 30 and 60 frames per second, it comes in a protective waterproof housing for first person perspective action photography. It also has a time lapse still photography mode that can be set to capture photos from once every 2 to 60 seconds until stopped (which would be useful for documenting a wilderness trail). 
- Photosynthetic man-made material that is based on frog-foam that can capture carbon dioxide. 
- A new process to generate electricity from both light and heat could lead to more efficient solar power capture, but will it be less expensive?
