There's cloud computing, and then there's CLOUD computing

Skipping straight from the engineering of holographic information storage to its geo-tech conclusion, here's a dramatic thought from BLDGBLOG: Could we write data directly to the Earth's magnetic field?

For several years I've been fascinated by what might be called the geological nature of harddrives – how certain mineral arrangements of metal and ferromagnetism result in our technological ability to store memories, save information, and leave previous versions of the present behind.

...This reminds me of another ongoing fantasy of mine, which is that perhaps someday we won't actually need harddrives at all: we'll simply use geology itself.

In other words, what if we could manipulate the earth's own magnetic field and thus program data into the natural energy curtains of the planet?
