Faucet attachment seems wasteful

Charging from a stream seems great, if one's available.  If you have a stream of rainwater coming off a roof, it looks like it could work OK as long as the rain lasted.

I'm not happy with the idea of attaching it to a faucet.  They say "only one gallon per minute" but a 2..3 hour charging time seems like it would often mean running 120..180 gallons of clean drinking water down the drain.  Power generation runs a pump, which pushes water through a network of pipes, which turns the HydroBee generator, which charges some batteries.  Then there's whatever energy is spent on water treatment and running the local sewage plant.  The faucet attachment seems like a really low efficency approach to charging batteries.

I guess this hydropower generator will require a flowing stream for mechanical rotation .

May be the rain water will not be able to create that much rotating torque.

I too like the concept of the personal hydro power turbine. How much flow of water is needed for the turbine to function properly? Does it work with rain or does it need smooth flow of water?

My vote goes to the "Personal Hydroelectric generator". It will be great help for those campers and trekers  exploring wildlife, those surfers and water rafters. They can keep their mobiles charged while away in the wilderness.

self-healing?

Scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have created a self-healing battery electrode, which could help pave the way toward more robust high-capacity batteries for electric vehicles and portable electronics.

So, what's the catch? What is standing in the way of getting this technology out of the labs?

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
