Interesting product

[Dennis]

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!

[amdx]

They're out of stock! The faucet unit is only $6.99, for that price
I'd tear it apart just to see how it works.
I expect someone to explain it. ;-)

Green water is colder than blue water? That's wrong!

It cannot be that hard to generate the juice required to fully
illuminate 20 LEDs.

English power cord... The BROWN wire is always 'the hot'. It is easy
to remember if one just remembers hot and cold.

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.

Yeah you could but how would you do it in a consumer product flogged for
$10.

Found a video here, doesn't look as bright as in the advert:

In an apartment, where the water is free, one could use such a device
to generate some of their electrical need. Wasting much free water, of
course. But folks do that all the time these days.

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 ;-)

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.

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

Now you are talking shit. Errrr I mean sewage.

Miles of pipe under most cities. Don't forget storm water. I still don't
get why we build houses now with a roof then effectively install another
roof (solar panels) on top to be efficient.
I guess the problem is there must be a dollar in it.

The above mentioned product (I am unable to follow the link at the moment
thank you Telstra) I assume is designed to be replaceable over serviceable.
I am also guessing at the mentioned price they plan to flood the market.

Businesses are in business to make money.

Then you must live in one of the following countries...U.S.A... Liberia...Myanmar.

If you live in the US and don't work in a technical field then you are probably just
ignorant of the real extent of metrification. The unit of temperature is just the lowest
common denominator in the sensible (metric) units vs. silly (US/Imperial) units
debate which was won a long time ago by near universal consensus. (Except for the
obstinate and stupid trio of the U.S.A., Liberia and Myanmar)

http://science.howstuffworks.com/why-us-not-on-metric-system.htm
"Many myths swirl around the metric system and U.S. involvement with it. Let's dispel a few. First, the relationship between the
metric system and the United States dates back to the 18th century, not the 1970s. Second, all countries have either fully adopted
or legally sanctioned the International System of Units, or SI, the modern form of the metric system. That includes the U.S.,
Liberia and Myanmar, three countries often listed as the sad-sack metric losers."

Nothing like a good Euro-hand-shower, especially when you are holed up
in a lonely yank hotel...........can't get no...... satisfaction etc......

When you're onto a good thing, stick to it. (or vice versa!)
