Yeah, this sortof thing works if you have monopoly in the good bussiness and offer the bad bussiness for free with it. Like M$ did.
But here they have monopoly (not really but good enough) in the bad bussiness (AOL) and are trying to attach it to a good one with no monopoly (Time). Big mistake if you ask me...
Nope, it's not of the future. The HDD future belongs to something else: platter-level RAID systems. That is, you make a RAID with each head/platter being one unit. It has been tried in the past, but the problem was that the heads would get slightly misaligned in time and you'd have to reformat too often. I think that with the current technology it should be possible to decrease the data density (which is ok now) and use a stronger recording signal (fatter tracks) to allow for some head alignment change.
Once you do this then ALL heads will be able to read or write simultaneously (in parallel) rather than one at a time as they do now.
Only question is -- how long till they decide to go for it.
Hmm, their "turbine" looks very similar to the waterpump on my VW. And that VW pump was designed so well that they kept that design from around 1974 till 1999 (that is my WP fits any 4-cyl VWs in that year range!).
I think if you design the output slot right you'll get most of the radial flow pushed up the exit. The only thing they missed is a curved intake (pointed forward), but that's minor. Might add some drag at 200mph though!

The way I see it the impeller can actually be the rim and not rotating with respect to the tire, thus it wouldn't need seals/bearings like a regular waterpump does.
On the other hand, there has to be a wheel cap stationary with respect to the body, that has a rear-facing slot for the propulsion jet. Now between this cap and the rim you'd need a seal, but if you make the cap ultralight then the seal won't be that hammered.
Of course, you could put the impeller on bearings and work it out that way, but I don't think that's necessary.
Well, they talk about coastal tidal currents (which are local), not the Gulf stream and such.
Anyways, the problem I see with this is that strong tidal currents are not found everywhere. It smells like what they are using is the effect you get when a lot of water rushes from the ocean through narrow straits to fill the gulf behind. This creates useful high-speed currents that can spin your turbines. I doubt, however, that normal tides along an open beach would produce currents strong enough for the job.
So the application might be useful in Norway which has ALOT of fjords along its coast to create those straits with gulfs behind, but may actually be too limited to be useful in the grand scheme of things.

But look mister new internet connection customer. If you get AOL you get the Time magazine online for free, otherwise you don't!
Might get a few Joes to decide quicker, but if you ask me I doubt those who do it would have had the balls to choose something else anyways.

Yeah it doesn't address latency, just data rate. The neat thing is that you can still make an external RAID of these.
