The Download: sleeping in VR, and promising clean energy projects
This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.
Inside the cozy but creepy world of VR sleep rooms
People are gathering in virtual spaces to relax, and even sleep, with their headsets on. VR sleep rooms are becoming popular among people who suffer from insomnia or loneliness, offering cozy enclaves where strangers can safely find relaxation and company-most of the time.
Each VR sleep room is created to induce calm. Some imitate beaches and campsites with bonfires, while others re-create hotel rooms or cabins. Soundtracks vary from relaxing beats to nature sounds to absolute silence, while lighting can range from neon disco balls to pitch-black darkness.
The opportunity to sleep in groups can be particularly appealing to isolated or lonely people who want to feel less alone, and safe enough to fall asleep. The trouble is, what if the experience doesn't make you feel that way? Read the full story.

Inside the conference where researchers are solving the clean-energy puzzle
There are plenty of tried-and-true solutions that can begin to address climate change right now: wind and solar power are being deployed at massive scales, electric vehicles are coming to the mainstream, and new technologies are helping companies make even fossil-fuel production less polluting.
But as we knock out the easy climate wins, we'll also need to get creative to tackle harder-to-solve sectors and reach net-zero emissions.
Our climate reporter Casey Crownhart spent last week in Washington, DC, at the annual Advanced Research Projects Agency for Energy summit where high-risk, high-reward projects are showcased. Read about some of the most intriguing projects that caught Casey's eye.

The big story
How we drained California dry
The residents of California's flatlands have learned to watch the sky with an uncanny eye. Some days when the brutal summer sun sparks wildfires, they breathe the worst air in the world. Drought won't loosen its grip on the land, and the insufferable heat lasts well into October.
During the driest decade in state history, valley farmers haven't diminished their footprint to meet water's scarcity but have added a half-million more acres of permanent crops-more almonds, pistachios, mandarins.
They've lowered their pumps by hundreds of feet to chase dwindling water sources, sucking many millions of acre-feet of water out of the earth that the land is sinking. This subsidence is collapsing the canals and ditches, reducing the flow of the very aqueduct that the state built to create the flow itself. Read the full story.
