Techbreak - January 2008

This car runs on air!

January 23rd 2008 11:11
I wrote about this earlier and it looks as if it's going to take off... Guy Negre, French inventor, created a car that runs on compressed air and Tata, the Indian car manufacturer is going to mass produce the vehicles, selling them for about $10 000.

Put your hands in the air like you just don't care!

Did you hear me? A car that runs on air and costs $10 000? This could be the spark we've been waiting for.

From Plenty Magazine, the car can run for about 60 miles on one tank of air, which can be filled by an industrial compressor in two minutes, or by plugging the vehicle in for four hours.


The car has plenty of critics... after all 60 miles isn't a lot, and at the end of the day, the car is still using electricity, which is polluting somewhere.

But this is a great start - and a brilliant one... a gasoline car uses the energy of the fuel to compress air... this just bypasses the fuel and uses compressed air to start. Efficient, I'd say, especially as the technology matures.

Yes, it's using electricity, but this way, we have more control over the efficiency of the energy generation, even mitigating the pollution by using other technologies, such as solar or hydro.

Of course, we'll have to see how this pans out... it's still unknown how safe the vehicle is, carrying around a tank of compressed air,

This will become increasingly more common as the bandwidth in all that dark fiber starts to get chewed up... ISPs used to offer unlimited download connections, but these programs were based on the idea that people use a connection sporadically.

Things have changed quickly since then, especially with the advent of Bittorrent, a fantastic method of downloading large files without using the hoster's bandwidth.

The service providers are a little frightened by this concept... after all, you let your Bittorrent client download all day and all night, pulling enormous files over your connection. The network is constantly being used and the ISP starts to lose its profits.


Time Warner in Texas is going to eliminate their unlimited broadband plan, and replace it with $50 for 500 GB.

Admittedly, 500 GB is a lot of information. Are there people downloading more than that? At 4 GB per DVD movie, that's 125 full length movies... who could watch that much?

The post is from Gizmondo, and you know they've got something else to say:

"Supposedly, consumption-based billing is aimed at all you assholes downloading movies from BitTorrent—"heavy users of large downloads," the purported 5 percent that swallows "up to 50 percent of network capacity" in order to improve network performance. But this is, at least partially, BS.

Everybody is using more bandwidth than ever, and that is going to continue ramping up with services like Netflix and iTunes that keep pushing these "large downloads" into the mainstream. So, it might only hit a small percentage of users really hard right now, but soon enough it'll be hitting everybody, which is the real point."

Exactly right - the ISPs will have to face this eventuality sooner or later... everyone in the media distribution business knows for a fact that we'll move to sending media over the internet - with HD-DVD and BluRay coming up strong, that means bigger file sizes.

Leave your wireless networks open

January 17th 2008 09:49
I've got a wireless router at home, turning our phone-delivered broadband into a sea of wireless connectivity. I love the idea, though in practice, it still has faults...

One thing we were quick to implement was locking down the network. By setting up a secret key on the system, we're able to prevent our connection from being hijacked and used for other people's dirty business.

Bruce Schneier on Wired wrote a hugely popular article on keeping your networks open, letting people use them freely.

"To me, it's basic politeness. Providing internet access to guests is kind of like providing heat and electricity, or a hot cup of tea."

It's an interesting idea... and one that has a lot of merit. One thing that stops people from working remotely is the hassles with finding an internet hotspot to connect to. Where?

Schneier proposes leaving your wireless network unprotected and open... it sounds crazy, as if people would definitely steal it, but there's an interesting point behind it.

Why don't people steal old, beatup cars? It's because they're not worth anything... it's the same with Internet connectivity. People want to steal it because it costs a lot of money, especially here in Australia.

Imagine if every house in the neighborhood was broadcasting an open connection? Why would you bother to steal it?

Of course, this ideal scenario depends on everyone having the disposable income to support this crazy scheme.

Still, let's get there!

iPhone profile Steve Jobs presentation at Macworld
This week, everyone's been reading this fantastic article in Wired, which goes behind-the-scenes at Apple, to give us the deal with the iPhone, the super-hyped cellphone that brings us closer to having just one device for everything...

The story is called "The Untold Story" and with good reason: when the iPhone came out, people got jittery jammed with anticipation. Apple products are always well-designed, with the user's needs put first
