Saw this advert - shower head with LEDs to illuminate the water stream,
coulour indicates temperature.

<http://www.coolproductsusa.com/shop/led-shower-head-with-temperature-sensor/?fb_action_ids=3921615035746&fb_action_types=og.likes&fb_source=hovercard&fb_aggregation_id=246965925417366>


Supposedly without batteries or external power.

"No batteries and external power supply needed.
The color change tells you the water temperature.
Bright LED light.
Approved by CE & RoHS certificates.
Electricity is generated by hydraulic mechanism."


I wonder what mecahnism they use to generate the power & if it really is
as bright as the marketing pictures depict!


No doubt they will make a few dollars out of it!

You could in theory have a shower head that delivered 50 watts or so of
electrical power from the pressure drop.

Well, remove the restrictor, and you get that back.

So, the generator can be set (designed) to spool up until the drop
matches what a proper, restricted head would deliver.

They would always be red with me. My showers are 125 degrees.

EEs should be legally exempt from having to use low-flow shower heads. We get
all our best ideas in a good hot shower.

I get my best ones when having a brewsky. So should we exempt EEs from
DUI laws? Oh wait, something like that has already been done in ... you
guessed it ... Ireland:

Agreed!

Last year, when I did that three month gig on Long Island, I was holed
up in an Extended America Hotel with a typical weeny shower head.

So I went to the local Lowe's and bought two channel-lock and one
needle-node pliers and a European-style hand-shower.

Unscrewed the original shower head, and replaced it with mine (flow
restrictor removed) for the duration. (Probably a crime in NY State
:)

FedEx'd it back to myself when I left, and put the pliers and
hand-shower into my extended travel kit ;-)

If any of you ever remembers the others, you should go see a doctor and
get help for all of them, leaving just one. Hopefully, it will be the
one with half a brain.

My guess is, it has a vane in there the water must pass over and forces

it to spin. THis is most likely a magnetic coupled generator and simply
spins up with the force of the water..

It does not take much to light up LEDS.

It says in the description:

"Electricity is generated by hydraulic mechanism"

So Jamie's probably right.
