I have blogged about this strange theoretical invention before. Here is another more detailed view of exactly how a device would work that uses a tacyon stream to send internet signals into the past.  Actually how this would work is that the moment the first of these devices that accelerate tacyons beyond the speed of light is activated, the operator would start to receive signals from his future self. 

Google the future?  Well yes, a google search would be initiated, then the scientist, in the future time targeted by the search would send the search results into the time machine on the tacyon stream.  The result, gathered in the future, would immediately appear in present time.

This would allow the person controlling the machine to win every lottery and beat the stock market.  This would violate the cause/effect reality that we depend upon for our very existence.  Given the inevitable leak of this technology to wider and wider audiences, our whole frame of reference would disintegrate.  Pretty strange.

But how could the titanic amount of energy necessary be generated and controlled?  My idea is that a solar orbiting satelite could be built to collect the intense radiation from the sun to create a circular field that is needed to accelerate the tachyon stream beyond light speed and send it intro the past.

The information would be sent with laser communication to and from the satelite, and the satelite based accelerator would be used to google the future.  It's a good sci-fi plot, but let's hope it never happens!
