Silicon Out, Graphene In? [Gadgets]

Graphene also has a resistivity (opposition to the flow of electric current) of 1.0 microOhm-cm—which is 35% less than copper. That figure would also make graphene the lowest resistivity material at room temperature. However, impurities in graphine make it less effective than copper at transferring electrons (at least for the moment). Still, with some refinement, the future looks promising for graphene as our next "miracle material." [University of Maryland via Slashdot]
The Gadget: Olympus E-420, billed as the world's smallest and lightest DSLR
But in the end, the E-420 is not going to cut the mustard when facing off against the other DSLRs, although they do tend to list for $200 more. Its biggest weaknesses are focus speed and low-light shooting. In the standard Sensor AF mode, the lens has to back up and focus in every time; the Nikon D60, faster to begin with, doesn't work as hard refocusing on the same object a second time. In decent medium indoor light, the automatic shutter settings are just too slow. On top of that, there's no optical image stabilizer or vibration reduction, so you end up with a lot of frustrating shots like this one:
Or this one:
Then again, I was able to take some pretty nice pictures too, like this one:
In the end, the E-420 may be the smallest, the lightest, the cheapest and even the highest-tech, but it's not the fastest, and in this competition, speed matters one hell of a lot. [
Lina Fischer's coffee maker design is scrumptious and works rather like an espresso maker would, but is better looking (although less iconic than those little moka pots caffeine heads go bubbly over). It comes with its own induction-powered table station, but what really sets the Kahva apart from other coffee makers is what happens to the Joe when it's brewed.
As the water heats, the rising air pressure makes it flow upwards from the glass water chamber into the metal brewing unit. Once the coffee is ready, take it off the heat and the coffee will return through a filter into the Kahva's glass bottom via a vacuum that has been created by the cooling of the coffee maker. To pour, simply turn the grip and let the coffee flow. [
Samsung's latest introduction, the SCH-W420/W4200 in the video below, is a slender, iPhone-like handset with a 3.2" touchscreen, a lively user interface, and the kind of force feedback that the LG Prada phone could only dream of.
