Privacy is a public concern

March began interestingly for me this year, with two big meetings back-to-back, in Panglao, a tiny island in the Philippines. The first was with Privacy International, the London-based public service PI_Gang_Panglao.pngorganisation. It has worked tirelessly for over two decades to keep public awareness of personal privacy rights.

Surprisingly, for most people who hardly ever need to think twice about such an obvious attribute of free people, this right is fast vanishing around the world, and most dismayingly, in democratic countries. Continue reading

Doing less with more, or, fossil fools

I know. That could be about just about anything we humans do with the natural resources at our disposal – except manage the residue, it seems.

But this post is about spectrum usage, and energy. Odd combination. Eager readers of my tireless prose might wonder, since I have already posted here about alternate energy conversion routes, and about spectrum, at length (friends assure me it is entirely too much length, in fact. As Garth Brooks put it, I’ve got friends. On the other hand, maybe I don’t have a lot of readers).

Wind Power Sails Ahead

(Based on an email posting by Ralph – figment at boone stop com – following an inspiration from Dr Win Wenger: design and development by Ralph, including linked drawings. Thanks to Prem Saran for the link.
Following an angry comment from a reader that the post is obscure and turgidly written, I have made an effort to edit and hopefully improve it. I have put my ‘comments’ as asides, however, both Ralph’s original post and my comments are in first person voice)

(This is a) design for a wind-powered energy system that can tap at least 60 times as much energy as the United States Renewable Energy Laboratories states is available in a square meter of wind. The system does this not by some magical process (it is extremely mundane) but apparently by tapping into very large volumes of moving air, as seen in the sails of large sailing ships. With it, you should be able to easily reach single-digits megawatt/hours of power in windspeeds as low as 10 statute-miles- per-hour, or drive a pump with thousands of horsepower of kinetic energy in those same winds.

Less Power, More Power

A Little Energy Goes a Long Way

Somehow the concepts of ‘less is more’ and ‘small is beautiful’ do not ring out loud and clear in the community networking environment. Perhaps they are just too obvious: however, I suspect that for urban-focused networks, with their routers and access points dangling from eaves and out of windows, drawing energy from house utility connections, it is really irrelevant.

In the countryside, things are different. Networks stretch across the kilometers, lonely towers in remote spots relaying signals between clusters of homes, over jungle and desert, from hilltop to distant peak and down to the shaded valley below. In this scenario, efficient power solutions mean less money spent on expensive solar power, generated locally and guarded from the depredations of monkeys and men.

Needless to say, the deliverable goes further. In older systems of information delivery, mankind sought to create efficiency by centralising content creation in one place, transmitting across the world with megawatt transmitters, pumping powerful shortwave signals across the world. What price such efficiency, focusing on the packaging till the words became meaningless, the songs capsuled till the music couldn’t be heard.

How many times have I heard techies and engineers shake their heads and mutter, “There has to be a better way“? In the world of information exchange, evolved and transforming the age-old traditions of information dissemination, we find a semantic that neatly divides the e-Generation from its elders and [not-so-?]betters.
