Future Ships Could Float On Bubbles 314

MattSparkes writes, "Creating a layer of bubbles underneath a ship's hull could improve fuel efficiency by 20%. When you consider that 90% of the world's goods are transported by sea, the importance of this discovery is obvious. 'Conjured up from thin air at the flick of a switch, this slippery blanket will help transport a fully laden tanker or container ship across the ocean at higher speed, and using far less fuel, than ever before... There is currently no other technique in naval architecture that can promise such savings.'" The article looks in some detail at the engineering problems that will need to be overcome before this technique is practical.

The work by Engelbart (from PARC) directly led to the advances at Xerox PARC. Several people went from SRI to Xerox PARC in the early 1970's (where I worked).

The Xerox PARC team codified the WIMP (windows, icons, menus and pointers) paradigm, first pioneered on the Xerox Alto experimental computer, but which eventually appeared commercially in the Xerox 8010 ('Star') system in 1981

Hey, I remember an exchange with you in the past where you said something funny, and I put in my sig (see below). You also made some valid point about the topic, which I can't recall now. Anyway, I wanted to get in touch with you now because I'm considering a law degree and was hoping for some pointers. Your email address is hidden, so I'm stuck posting this reply and looking like a bit of a tool. :-) Anyway, you can email me at steveh (at) amnesiac.net

Thanks.

But how big is the code? Can it be handled over dialup?

Just another thing to teach my parents how to use. They need a button marked "set time on VCR."
