I’ve been talking to friends about how the waves can be tapped for electrical power here in the Philippines. I was telling them that the up and down motion of the waves can be used to drive a piston which would then drive a generator. The idea isn’t new, I’ve heard of it before but I was just wondering why it’s not being used in the country.

Now, the world’s first wave farm is up and running in Portugal. The Philippines could have done it if budget was allocated to it.

It’s free energy and is definitely eco-friendly. The Agucadoura which consists of three wave energy converters just like the one above currently produces a total of 2.25MW of electricity. Need more power? Just add more wave energy converters. I think I should build one of these when I get a house by the beach.

Art can be everywhere and in this case of nanotechnology demonstration, on nanotubes. Some guy in a white suit decided to etch the face of Barack Obama on a canvass so small you’ll need an electron microscope to see. Check it out below.

Soon, the days for finding Wi-Fi hotspots will be gone. Thanks to the companies who fought for the use of white-space - the unused television spectrum from 512MHz to 698MHz. Among these companies are Dell, HP and Google. With a vote of five to zero, the FCC had unanimously approved the conditional unlicensed use of white-space television spectrum.

What does this mean? Well, this means cheaper Wi-Fi with a wider coverage. What makes it cheaper is the fact that internet providers will need to put fewer base stations because this frequency range covers wider areas (think of television). Google co-founder Larry Page calls it Wi-Fi on Steroids. Dell on the other hand is taking steps by choosing to add a new wireless option to future laptops by installing radio chips that provide connectivity over the unused television spectrum.

I’m personally excited and want to see this technology implemented in the Philippines soon - but deep inside, I know I’ll have to wait.
