IT’S not so much clean and green as clean and white.
The world’s largest solar-powered boat, the Turanor PlanetSolar, is sailing into Brisbane, after crossing the Pacific from the Panama Canal.
She will go on show on Sunday at Brisbane’s Riverside Centre Pontoon and remain open for inspection until June 2.
The 95 tonne Turanor is making its only Australian stop on a world circumnavigation, aimed at showing that renewable energy technologies work.
She is the idea of Swiss businessman and electrical engineer Raphael Domjan, who is sailing the boat without the need for sails or a clattering, pollution-producing diesel engine chewing non-renewable fuel.
Pushing it along on its 50,000km world-first voyage is a solar photovoltaic surface area of 537sq m, with 38,000 solar cells.
Nearing Australia it struck big seas and overcast conditions, reducing the boat’s speed to just 37km a day, way down on its 200km-plus legs in fairer weather.
Her crew’s aim is to sail her at an average speed of 7.5 knots – just on 14km/h – which, they say, is about what a conventionally-powered oil tanker makes.
Solar panels are attached to outriggers that can be retracted in stormy weather. Energy is stored in batteries which can power the vessel’s electric motors without sunlight for three days at 7.5 knots.
Mr Domjan’s log details tough conditions for a solar-powered craft on Wednesday, with nose-on squalls to 74km/h.
“Distance covered during the last 24 hours: 20 sea miles (37km),” Mr Domjan said.
It was the first time the catamaran faced such tough conditions.
“We take every hit of the unchained ocean against our superstructure. The roar of the wind against our hull is deafening. One could have the impression of being in a cabin perched in the high mountains,” he said.
“…After more than 7500 miles in the Pacific Ocean which we covered in relative tranquillity, I believe that the greatest of all oceans has decided to show us how powerful it can be.”

KUALA LUMPUR: Petronas Dagangan Bhd has launched its latest RON 95 petrol – Primax 95 Xtra – which was previously known as the Mystery Fuel in the several blind tests that has been proven to offer better engine performance and fuel economy.
While being a much improved product, Primax 95 Xtra which is now available in over 950 Petronas service stations nationwide is still sold at the same regulated price of RON 95 fuel at RM1.90 per litre.
Primax 95 Xtra, whose development is inspired by Formula 1 technology, features a combination of advanced combustion improver and friction modifier to produce efficient combustion and reduce internal friction to extract maximum work for every drop of fuel burned.
In addition, the new synthetic detergent used in the fuel also provides a superior edge in cleaning the engine and maintaining its cleanliness for optimum performance.
The new fuel was launched by Prime Minister Datuk Seri Najib Tun Razak at the Twin Towers Live Concert held in conjunction with the Malaysian GP. Continue reading
One of the things that appears clear from some of the changes at Microsoft is that Steve Ballmer is pulling down some of the traditional siloes, and forcing groups to work together more closely. On stage at CES, Steve showcased four products, Windows 7 with an ARM future, Windows Phone 7, Xbox Kinect, and Surface. While he didn’t specifically talk about the new Windows 8 (the name for the next generation of Windows has not yet been decided), the proximity of these technologies has many of us wondering whether Windows 8 could be the Mother of all Microsoft OS offerings.

Antennas that use plasma to focus beams of radio waves could bring us superfast wireless networks
BEFORE you leave for work in the morning, your smartphone downloads the latest episode of a television series. Your drive to work is easy in spite of fog, thanks to in-car radar and the intelligent transport software that automatically guides you around traffic jams, allowing you to arrive in time for a presentation in which high-definition video is streamed flawlessly to your tablet computer in real time.
This vision of the future may not be far off, thanks to a new type of antenna that makes use of plasma consisting of only electrons. It could revolutionise high-speed wireless communications, miniature radar and even energy weapons.
Existing directional antennas that transmit high-frequency radio waves require expensive materials or precise manufacturing. But the new antenna, called Plasma Silicon Antenna, or PSiAN, relies on existing low-cost manufacturing techniques developed for silicon chips. It has been developed by Plasma Antennas of Winchester, UK.

Salam and greetings to all.
There’s this buzz about YTL’s Yes 4G mobile internet with voice. So I decided to check it out myself.
Yes. 4G is about network created for mobile internet with voice, where 3G is about voice network with data added. That’s why 3G mobile internet is sluggish.
You can already register your interest, reserving an email address to you, and even choose what mobile number that you want to use. Well, 018-3318469 number is no longer available.
Some of the early facts about Yes 4G mobile internet that I gathered from the website
- There’s no multiple plan for multiple speed and quota
- Pay only for what you use, just like electricity
- 65% of covered during the first launch, so it’s not the Klang Valley to use first thing
- No SIM card required to use this, even you can use it on your existing phone
So, since it’s no string attached thingy, just go and register you interest here.
And they better reveal something good, 12 days from now. That will be on, 19th November 2010.
There has been more talk about 4G (fourth generation) mobile broadband recently and Nokia Siemens Networks (NSN’s) has announced that the first 4G field trials have been completed in Berlin.
As 4G seems to have taken a step closer to reality, I decided to do some research and find out what advantages 4G may offer over 3G. The specifications for 4G are not standardized yet but the following 3G vs 4G table gives an idea of what 4G is likely to provide.
|Frequency band||1.8 – 2.5GHz||2 – 8GHz|
|Data rate||Up to 2Mbps||100Mbps moving – 1Gbps stationary|
|Access||W-CDMA||VSF-OFCDM and VSF-CDMA|
The existing 3G W-CDMA standard will be replaced in 4G by VSF-OFCDM and VSF-CDMA. VSF-OFCDM allows extremely high downlink connections, both indoors and outdoors. VSF-CDMA provides high-efficiency, high-speed packet transmissions for the uplink.
The 4G adoption of concatenated FEC (Forward Error Correction) will allow much larger data packets to be transmitted and at the same time reduce the bit error rate. This will increase the overall data through-put.
One of the main advantages that 4G technology will have over 3G is higher data rates. This will benefit the end user by allowing faster access to multimedia and video while on the move.
We may still have to wait a while for 4G though, as it looks like 4G networks won’t be launched until 2008 and won’t become widely available until 2010.
