China Vows to Stop the Rain

Since the Olympic stadium doesn't have a roof, the Beijing Meteorological Bureau has been given the task of making sure the games remain dry. According to Zhang Qian, head of weather manipulation (best title to have on a business card ever) at the bureau, they've had success with light rain but heavy rain remains tough to control. I see a hurricane cannon in some lucky country's future.

what the post-opening propaganda will be like if that day turns out to have sunny blue skies...

Cloud seeding and cloud freezing?

Not exactly 'new' tech...the silver iodide version's been around forever, and the liquid nitrogen version doesn't sound particularly revolutionary.

It does, however, go along with the Chinese cultural desire to control the elements, which heretofore has been embodied mostly with the rivers--the legendary "Yellow Emperor" was the first to stop the flooding of the Yang Tze; the current government has thrown massive resources into the Three Gorges dam. Controlling the rivers has been traditionally (as far as I recall, anyway) seen as evidence of controlling the land, and thus of being a legitimate government.

Controlling the rain, then, would be an extension of this.

Controlling the water means you control the people, as well--remember, China has been, traditionally, a largely agricultural country, dependent upon a certain flood cycle.

If you control the rivers, you control the land they feed and drain. If you control the feeding and draining, you control the people who need that feeding and draining to survive, and to grow food. If you control the people who grow food, you control the people who need food--and that's more or less everyone.

It all comes back to the water.

Re:Rain's better than smog

That sure seems more reasonable. But what would make the most sense, to me, would be to have used some of that cheap labor to build some indoor stadiums and HEPA air filters. I mean, who wants to sit for hours outside breathing air that, on most days, is considered "very dangerous to breathe," raining or not?

Perhaps heat.

Believe it or not, the United States already has this technology. And it's in the hands of the rednecks.

There's a stock car track in Bristol, TN that holds 165,000 people, and has 43 800+ horsepower cars running around an oval just a shade over a half mile long. This generates a lot of heat-- body heat, engine heat, heat from tires cornering on concrete fast enough to turn fifteen second laps. Enough heat that, as long as the race is still running, rain clouds can blow over Bristol, drench the entire city with rain, but the pocket of high pressure due to the heat (and possibly some counter-clockwise swirling motion due to the cars) will keep the rain from passing directly over the track.

If the caution flag flies and the cars slow down for too long, thus slowing the heat output and cooling the track, the rain may start to fall on the track, but it takes one heck of a storm to make the rain fall while the race is green-flagged.
