  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Renewable Energy from Evaporating Water

"Simple devices made of bacterial spores, glue, and plastic may allow capturing energy from evaporating water. This video explains the motivation behind our work and the exciting process of scientifically driven innovation. The contents are based on the publication: 'Scaling up nanoscale water-driven energy conversion into evaporation-driven engines and generators,'" Nature Communications, 6:7346 (2015).

This seems extremely silly when promoted as a potential source of renewable energy.

Interesting science for sure. Lots of new ideas and applications to learn from but..

Solar Energy + Batteries = Best Solution

I saw this the other day on the tube, and noticed that the energy produced must be far less than the energy used to pump the water to the top of the 'motor', as much of the pumped water evaporates to the atmosphere, going unused by the machine. That makes this interesting, but more as art than a useful device in most cases, unless it's installed below a natural water source, in which case why not just do micro hydro.

Upvote. Not for current applications but for pure science.

I think there could be successful applications of this if employed as a power source for extremely-small-scale, possibly autonomous and/or remote, systems.

Effort put into recording the video > energy "produced" by devices.
