Mouse Creater, Douglas Engelbart Turns 85 Today

Douglas Engelbart apart from the First Computer Mouse invention, is credited with many other inventions

Mention the name ‘Engelbart’ in any circle — preferrably a tech group — and you will have people saying, “Isn’t that the guy who created the mouse?” This would indeed be right but Engelbart, who turns 85 on Saturday, was also responsible for a lot of other creations.


In fact, he and his team showed so many new technologies on Dec 9, 1968 in San Francisco that this is usually hailed as ‘The Mother of All Demos’. Some of the things demonstrated at this convention — apart from the ubiquitous mouse — include email and hypertext, something that all of us use. Things that not everybody uses, but are still popular, were videoconferencing and a collaborative real-time editor, which were also shown at the demo.

But this said, Engelbart remains firmly entrenched in our minds as inventor of the mouse, probably because this is a solid, physical object that we use to interact with computers on a daily basis.


As dougengelbart.org puts it, “Doug Engelbart is best known for inventing the mouse and other seminal computing tools; however, his greatest innovations have been in the visionary strategy he devised for bootstrapping the innovation process, creating a very fast sort of turbo-charged learning curve in his lab, out of which emerged unprecedented levels of breakthrough innovation.”

Much of his innovation was driven by the fact that he had at one time been a radar technician and, therefore, understood how information could be shown on a screen. He felt that one day, everybody would be sitting in front of such screens, communicating and collaborating with each other. Nobody could have described today’s world of the Web better.


Of course, in his time, not many could have understood the concept of what the Web could offer - in fact, even in the mid-90s, when the Web was operational, many people had difficulty in understanding what its true potential was. The greatness of Engelbart lies in the fact that he could envisage a future before anybody saw it,
and more importantly, contribute towards making it happen.

No doubt, people in his time would have ridiculed him for some of his ideas, which may have seemed like sci-fi then, but as he put it so succinctly, “The rate at which a person can mature is directly proportional to the amount of embarrassment he can tolerate.”

NICE TO KNOW

• The pointer device was called a mouse because the wire connecting it to a computer looks like the tail of a mouse
• The pointer that the mouse moves on the screen was originally called a bug
• Engelbart never received any royalties for his mouse invention

Wow!!! A Car that Runs Solely on Water.

TOKYO: Tired of petrol prices rising daily at the pump? A Japanese company has invented an electric-powered, and environmentally-friendly car that it says runs solely on water.

Genepax said that a litre of any kind of water – rain, river or sea – is all you will need to get the engine going for about an hour at a speed of 80 km.

“The car will continue to run as long as you have a bottle of water to top up from time to time,” Genepax CEO Kiyoshi Hirasawa said. “It does not require you to build up an infrastructure to recharge your batteries, which is usually the case for most electric cars,” he added.

Once the water is poured into the tank at the back of the car, a generator breaks it down and uses it to create electrical power.

The company said that a proprietary unit splits the water into hydrogen and oxygen using a chemical reaction, which provides fuel for a hydrogen fuel cell to run the car.

It also insists that the new process produces hydrogen from water for a longer time than the existing method.

Genepax informed that power is generated by its Water Energy System (WES) by supplying water and air to the fuel and air electrodes, the system being similar to that of a standard fuel cell.

Its fuel cell system – the company added – has an output of 300W. Genepax has mounted this system in the luggage room of a compact electric vehicle ‘Reva’, manufactured by Takeoka Mini Car Products Co Ltd.

Now, Genepax is planning to provide 1kw-class generation systems for use in electric vehicles and for residential applications.

While the current production cost is about $18,522 (Rs 8 lakh approx), it is estimated to be reduced to $5,000 and even lower if the company succeeds in mass production. ANI
