If you're in such a hurry, I would not attempt to do all you've outlined. As GillH007 noted, it's not realistic to do the desert in a day. Taking in the geysers, which you can drive to or possibly get a guide in taxi instead of doing a tour, is something that unfolds over time, from dawn to early light. There are magnificent changes in the light that occur, and different geysers and streams of water that come to life, that you need time there. But that means rising at a very early hour. And unless your idea of visiting a location is rushing from place to place, you will want to drink in all of the beauty and culture there is to see at the three locales you mentioned. Also as GillH007 mentioned, you're in the high desert. It's incredibly dry; I drank a 2-liter bottle of water and was still needing more water. It's very easy to get dehydrated, which is dangerous. And the altitude can lead to sickness, especially if you rush from low to high, or vice versa. In the morning, you'll feel like you're in the Northeast during winter. It can be below freezing when you set out in early morning. You'll need layers of clothing and to strip down to summer clothing by mid-afternoon. But regardless of the temperature, its very dry. If renting a car, you'll want 4WD, since many of the roads have potholes and lead off-road to the destinations. But there aren't a lot of gas stations, so you need to be sure you watch your gas and don't end up stuck on empty. I stayed 3 nights/4 days and could easily have stayed longer. There's great beauty and serenity in San Pedro de Atacama. Its whole vibe is to slow down and not rush. I wouldn't recommend a one-day trip.
