Dreams do come true… The hoverboard in Back to the Future, Part II made me really, really want to be living in the year 2015 and had me daydreaming all the time, but as I get older my pragmatism and cynicism lead me to believe we would definitely not have hoverboards by that time. I might just be proven wrong in the most awesome way possible: by real hoverboards.
That’s because a group of physicists claim to have figured out how to reverse what’s known as the Casimir force, causing objects to repel from each other rather than be attracted.

The force is due to neither electrical charge or gravity, for example, but the fluctuations in all-pervasive energy fields in the intervening empty space between the objects and is one reason atoms stick together, also explaining a “dry glue” effect that enables a gecko to walk across a ceiling.
Now, using a special lens of a kind that has already been built, Prof Ulf Leonhardt and Dr Thomas Philbin report in the New Journal of Physics they can engineer the Casimir force to repel, rather than attract. Click on link to read more…

BTW, this is different from magnetic levitation or nitrogen thingy… This is really “THE” levitation… requiring only one part to do the work… OHHH!… I can’t wait…

NanoNuno® Umbrella

September 22, 2006

Finally, the humble umbrella has evolved. This umbrella does not create a mess or accidents indoors after coming in from the rain… just give it a good shake and it will be clean and dry right away. It just like any umbrella, but the difference is nanotechnology.

Developed in Switzerland and modelled on a natural phenomenon of the lotus leaf. In nature, a fascinating effect is produced by the microscopic, rough nanostructure on the leaves of the lotus plant: Dirt and moisture simply roll off. This is because there is a much smaller surface area to which things can stick than on a smooth surface. Nanotechnology… great stuff.
