Plants fare well in 'smart' greenhouse - Duration: 2:02.Worldwide, about nine million acres are covered in greenhouse vegetable production.
And that's roughly the size—two times the size—of New Jersey.
So, that's a considerable amount.
So, we can save an awful lot of climate-changing greenhouse gas emissions if that electricity
was generated onsite.
A solar greenhouse is a dual-use facility.
It can be used for growing plants but it also generates it's own electricity.
That electricity is then used to support functions of the greenhouse.
We've grown a variety of of different crops, many of which are important to the central
California—central coastal region—around UC Santa Cruz, including strawberries, tomatoes, lettuce.
But in this study we found that most species grew just fine under the altered light conditions.
The growth of tomatoes and the number of tomatoes was pretty much the same under the pink-colored
glass house compared to the clear conventional glasshouse.
This technology developed by Sue Carter and Glenn Alers of the Department of Physics at UC Santa Cruz.
So, the color of these is because of the dye that's embedded in windows.
And the dye absorbs part of the sunlight and delivers it to thin photovoltaic strips that
are embedded in the plastic.
And that's where the electricity is actually generated.
The visible wavelengths of sunlight include all the colors of the spectrum.
These panels absorb the green, which plants don't use, and part of the blue.
And that's part of why we weren't sure how plants would grow and develop,
because plants like blue light and they like red light.
When we measured photosynthesis, we also get a measurement of how much water the plants are using.
And we find, actually, that they use about five percent less water when they're growing
underneath the pink glasshouses.
If you multiply that by nine million acres globally, that's a potential huge amount of water savings.

UPDATED Zooz, GE, Lutron, and Leviton Smart Wall Switch Review - Duration: 12:14.- Looking for smart in-wall switches to
enhance your smart home?
Today we're gonna look at the new Z-Wave plus
smart switches from GE and Leviton.
And the new kid on the block, which is Zooz.
Stay tuned.
(tech music)

compensation for making this video.
All product links in the description below are affiliate

Some of the switches shown in this video were provided
to me for free from manufacturer, however the video should
not be considered an endorsement for any of these products.
Hi again, John Stone the DIY smart home guy on
the channel that's all about helping you make
intelligent home automation decisions for your
affordable smart home and if you're looking
for an in-wall smart switch, this video is for you.
Last year I made a similar video about the GE
and Leviton Z-Wave switches and include the Lutron
Caseta switch for good measure.
Since GE and Leviton have released Z-Wave plus versions,
I decided to update the video.
There's new stuff going on so even if you've
watched the old video, it's worth your time
to see what's new.
Mainly because there's this new kid on the block.
The folks over at thesmartesthouse.com were kind
enough to send over their entire line of Zooz Z-Wave
plus smart in-wall switches.
Zooz is the house brand for thesmartesthouse.com
and so far, these switches seem pretty cool.
They also have a number of other products that you
can check out on their website.
It's also important to note that since my last video,
Leviton has updated their switch design
which makes me pretty happy.
In short, the new design encompasses a true
rocker panel instead of the old switch that
was pretty much stuck spring loaded in the on
position and to turn the switch on and off
you always had to push down to the off position.
And in case you're wondering, let's get
into why Z-Wave plus is better than regular old Z-Wave.
I left a link to a video that goes into more detail
about Z-Wave plus in the description,
but in short, Z-Wave plus is comprised of a new
Z-Wave standard and a new chip.
The chip offers a 67% improvement in range
which makes your mesh network stronger.
It also boasts a 50% increase in battery life
and a 250% increase in bandwidth.
These features should help improve the response speed of
the device as well as improve the signal reliability.
Now I don't plan to run out and change all of
my normal Z-Wave switches all at once,
but I do plan to replace them over time.
Each of these switches costs between 30 and 45 bucks,
so let's break down the prices as found on
a popular shopping website.
So when we're looking at the standard paddle-style
switch for the on/off, you can find the Zooz paddle
switches for about $33, the GEs for 38,
the Levitons for 45, that Lutron switch
is usually gonna be 50 to 60 bucks so I put
it down for 55.
Now all three of these have a three-way on/off
capability, but the nice thing about that Zooz
switch is you can use a regular three-way
switch as the add-on switch.
Now what that means is for the GEs and the Leviton,
you're gonna be paying anywhere between 10 to 18 dollars
for that add-on capability.
Where with the Zooz you can just reuse that three-way
switch to make your three-way configuration with
the Zooz smart switch.
On the Lutron side, you're gonna need a pico
remote if you wanna three-way configuration.
When we look at those paddle dimmers,
those are a little bit more expensive
even on the Zooz side you're gonna find
that Zooz for about $40.
GE Dimmer 38, Leviton around 45,
and that Lutron those prices stayed pretty consistent.
Now, again you're gonna need the add-on switch
for all of these other switches.
You don't need one with the Zooz,
however because you're using a regular three-way switch,
you're not gonna get the dimming capability out of
that secondary switch box, so the Zooz
on the primary one will be the only one
that will allow you to do the dimming,
you're just gonna hold it down and it's gonna
turn the brightness of the light up,
hold it down, turn the brightness down.
But on the secondary side, this is still
only gonna turn it off and on.
Now the nice thing about this is when you
turn it on from the remote's switch,
it will remember the last of the dim position,
but if you turn it on and it's not bright
enough, you are gonna need to go over to
the other switch and turn the switch up
manually or you're gonna need to do it
from an app or from your Amazon Alexa or Google Home.
Now when you look at these switches side-by-side,
they're all gonna look pretty similar.
Some minor differences are going to be
the way the indicator light comes in here,
I can't find an indicator light on this
particular Leviton model.
But the Zooz and that GE switch look
pretty similar.
Both the Zooz and the GE have the
fins on the side here, in case you
don't know, that's what these little
things here are, is their heat sink fins.
If you put these next to each other
into a wall box, you're gonna need to
remove those fins so everything fits
in there just fine.
So that's that.
The Leviton switch does not have the
heat sink fins on the side,
it looks like they found another way
to solve their heat problem.
When we turn these things over,
again, the GE and the Zooz are
gonna look pretty similar.
And the Leviton does look different
and you have more of the little vent slots there.
These again are all Z-Wave plus switches
and they're all pretty nice.
Now let's rock them over on the side real quick
and just look at the profile of those rocker switches.
So you can see the lowest profile of them all
is pretty much on that Zooz right here,
it's got a nice action to it.
It's kind of firm to touch.
That GE switch, it's a little more
(mumbles) of the bezel than that Zooz is,
and again it's kind of firm to the touch.
And that Leviton switch, but it's got
a nice light touch to it.
Very responsive, you don't have to push it real hard.
So it's not the big positive action that you
have to get on the Zooz and the GE switch.
But all in all, these are all three really nice
Z-Wave plus in-wall switches.
As I mentioned, thesmartesthouse.com sent me
these switches for free in hopes that I would
mention their website.
I haven't decided if I will or not.
♫ I bet you think this song is about you, don't you
That was creepy.
But anyway, there's a link to thesmartesthouse.com
in the description below.
They were also nice enough to provide
a coupon code for DIY smart home guy channel supporters.
This coupon will get you 10% off of purchasing products.
You can find the coupon code over on my patrion page,
that's patrion.com/diysmarthomeguy.
Now the Zooz switches come in these normal
decor or paddle-style switches as we
were showing you earlier.
And they also have these toggle-style switches.
And these are available as both dimming and non-dimming.
One of the things that people complain about
a little bit, and this is with all of the
toggle-style smart switches, not just the Zooz,
is that these things stick straight out.
And some people don't like that, they're just
used to all their life seeing these things
at that angle and they don't like the
fact that it sits there in the middle.
But the paddle switches, you know,
these rest in the center also but because
they're such a low profile there, you don't
really tend to notice that they rest
in that center configuration as much.
And again, when it comes to that three-way
switch configuration, not needing that
add-on switch can be a big deal to some people.
As Edward recently asked, "If I use a Z-Wave
"smart switch, do I need an add-on switch?"
This is one of the most popular questions
on my three-way switch installation video.
And if you're using a GE, Leviton or Lutron
switch, the answer is yes.
You'll need to spend an extra $15 to $20 on a
special add-on switch or pico remote.
But that's not the case with the Zooz in-wall switches.
They designed their switches to work with
a normal three-way switch in the auxiliary box.
Meaning, the box that doesn't have the smart switch.
Now take note, you'll need to rewire the
regular three-way switch, but you don't
need to purchase an add-on.
I'll be showing you how to wire the Zooz
in a three-way application in an upcoming video.
So now's a good time to subscribe.
You'll also wanna slap that bell icon
to be notified when new videos are released
or if I stream a live broadcast.
Another popular question that I get is
"Do I need a neutral wire to make this switch work?"
For the Zooz, GE, and Leviton switches,
the answer is absolutely yes.
Now I've seen advice on some message boards
that recommend using a bare ground wire
in place of the neutral wire if you don't have
the white neutral, but I'm not really
gonna recommend that here.
If you're absolutely sure that you don't have
a neutral, you may want to check out the Lutron
Caseda line of switches.
I did a video that installed this switch
not too long ago.
You'll recognize this switch as the one
that I use to control my bar light.
It's a great switch and it gets pretty good reviews.
So let's talk about how to get this Zooz
installed into the smart things app.
When you go to bring this thing into your
smart things, or wink up,
you'll notice that the instructions tell
you to turn the switch off, then on, then off.
This is a no-go according to Zooz.
The proper way to do this is to
tap on the switch three times in the up
position within a couple of seconds.
So let's get this into the smart things app.
So we're gonna come over and we're gonna
hit that little plus right there in the
upper right hand corner.
Let's...
Okay, so we tap that up three times
and you can see that the light came on,
that's annoying, and that brought it
in as a Z-Wave dimmer.
So we'll select that.
And we'll rename that.
Okay, so we're gonna go in, we're gonna
look at that dimmer.
Right off the bat you can see that you
have on and off.
And you can see that that brightness level
came up to the last level that it was set at.
And you can just swipe that around on the app.
And hit that down pretty low.
So lets see how low we can get it.
Sometimes how low the light will go is
a function of the light bulb more than it
is the switch or the app.
Okay, removing it should be just as easy.
Let's go into that Zooz dimmer there.
And this time we're going up into settings
and we're just gonna say remove.
And we'll go tap that three times.
This time I did it three times in the down position
and it has been removed, there you go.
Okay so let's go over to the wink app
and we'll essentially do the same thing.
Okay so on the wink up, we're gonna follow
the same process.
This time we're gonna go down to
add a device.
Scroll down here to lights.
And you won't see the Zooz on here.
I'm gonna have a little bit of fun.
I'm just gonna actually click the
GE in-wall smart dimmer.
Just for fun.
Connect now and we're gonna tap up
three times on top of that switch.
And we have a success.
Done.
So that's the thing.
I believe personally, that the way
wink does this, is as long as the device
is similar to the one you're trying
to pair, it's gonna bring it in just fine.
So you don't have to worry about it too much.
We could have just used a generic Z-Wave switch
and that should have worked as well.
But in this case, I just wanted to try using
the GE and it did fine.
So we'll bring that in, there it is.
So it's the one called light bulb.
We are going to turn that light bulb off
and it's gonna ramp down.
Now the folks over at Zooz also told me that
at this time you can not control the ramp rate
of that switch, however they are working on
a firmware update to allow you to do that.
So we'll be looking for that very soon as well.
But again, same features that you'd have
here in the wink up, turn it off and on,
as well as control that brightness level.
So I gotta admit, the last product that had
me this excited was the Innovelis two channel
plug-in module.
So it's definitely worth checking out.
If it passes my lab burn in test,
this is my new go to wall switch.
Especially considering the price.

That was creepy.

Hello World Smart Contract With Solidity | Ep 2 - Duration: 8:42.Hi guys and welcome to the second episode of Eat The Blocks. Today we are going
to create a simple hello world smart contract with solidity so let's jump to
the terminal to first create the file of our smart contract - touch HelloWorld.sol
As you can see the file extension of solidity contract is called sol. Ok
cool so we have our file so now let's jump to our editor and open
the file HelloWorld ok so first we're going to
introduce the pragma statement so the pragma statement is used to tell the
compiler which version of solidity to use so type pragma solidity and then you can
specify which version of solidity you want so let's first try with a mistake so
actually the version of solidity that I've installed is 0.4.18 but in
this example I'm trying to use 0.4.19 which is not
available so let's see what happens if we try to compile this
so to compile a solidity contract there are different ways but as I showed you in the
previous episode I use an NPM package that already embeds the solidity compiler
in a easy to use command-line tool so let's just use this. So it's called
solcjs and then we need to specify the name of the file and then we need to
give it a command-line argument so --bin which means compile the bytecode of this
contract. So let's first try see what is going to
say. Parser error okay so I forgot a semicolon
so let's add this okay let's try again
Okay so now we have another error so source file requires different compiler
version. Current compiler is 4.18 but we asked for 4.19. Okay so let's fix this so
you're gonna replace 19 by 18 okay.
Let's recompile and this time it's going to work. Okay so now what happens if we
try another version lower than our compiler. Does it compile? Yes it compiles.
Okay but we're just going to switch back to the version exactly of our compiler.
Okay so now we're going to decrease the size of our terminal and we're going to
create our first contract statement. So in a single solidity file you
can actually have several contracts but for this episode we're just going to
have one contract so let me write it. contract hello world and then I'm going
to open the curly brace okay so now I have my contract and all my code is
going to be inside this contract statement then in solidity we have
variables. Each variable we for each variable we need to specify the type
because solidity is a statically typed language so it's not like JavaScript
where you can just use directly a variable. In solidity you have to first think
about the type that will be used for your variable. So one of the most common
type of variable is string but we don't generally use the string type in
solidity but we use another type which is called bytes. And we can specify
exactly the type of this bytes type. So we're going
to say bytes32 and then we're going to specify the
name of our variable so bytes32 message okay so now we have one variable. Next
we're going to create a contract constructor. So the contract constructor
is a method that has exactly the same name as the contract. So I'm going to use
the keyword function and then I'm gonna use the same name of our contract
HelloWorld and then my constructor method can accept some parameters so I'm going to
accept the parameter of type bytes32 which will be my message and then in the
body of my constructor what I'm going to do is I'm going to assign the value of
myMessage to my message variable which is defined above so call my message okay.
So when this contract will be created for the first time it will be passed a
myMessage argument and this myMessage argument will be assigned to our
internal variable message and this variable message will be stored in a
smart contract and we will be able to access it but in order to access it
actually we need to create another function for this so let's do this.
function and you will be called getMessage. Okay so this function doesn't
take any arguments however this function is going to return an argument so we
need to specify the type of the returned argument with the keyword returns. We
need to open the bracket and we're going to return a type bytes32. Okay and then we
open the curly brace and we very simply just going to return
message. Okay and that's it! We just finished our smart contract. So now back to the
console and we will try to compile it to see if there is no error. So we're going
to repeat the last command. Let's see if everything works fine. Okay so let's see
what does the compiler tell us. So we have a warning here: "no visibility
specified". Okay so we're going to study this topic in the next episodes but
basically you can specify the visibility of methods and variables. And then we have
another warning:?function state mutability". Okay there is another keyword
that specify another property but we can just ignore this. Those are just warnings.
So now if I inspect the content of my folder I will find that I have another
file which I didn't have before so this file here "HelloWorld_sol_HelloWorld.bin".
So this contains the bytecode of my smart contract so let's try to inspect
this. Let's use "less".
okay so this is the bytecode of my contract. So we're going to use this
artifact in the next episode to send our smart contract to the network and have
it in the blockchain. That's it for today we did quite a bit. We learn about the
"pragma" statement, the "contract" statement, how to define a variable, how to define
its type, how to define a constructor, how to define function arguments, how to
specify the written type of a function. Tomorrow we're going to deploy our
contract to the testnet. Thanks for watching! If you like this channel please
subscribe. Bye bye!

QUT Smart Cities - Duration: 2:41.NARRATOR: In a single day, on this planet, more than 360,000 people are born.
The more people we have, the more complex our needs become.
The more complex our needs, the busier our cities become.
The busier our cities, the smarter we have to be.
And those needs can change in the blink of an eye.
As young people, we want our city to inspire us and enlighten us, to excite us and surprise us.
As parents, we want our city to be safe and secure, reliable like clockwork.
And when we're older, we want to know them and be empowered by them, a place of endless
opportunity.
But that's hard to expect from a city because sometimes things don't work as intended,
the lights go out, the traffic jams and for all our clever designs and plans, it feels
like our system just can't take it.
We need something new.
We walk around with the entire collective of human knowledge, with more technology that
they use to get to the moon, right in our pockets.
So why don't we use it?
Life shouldn't be made to fit a city, cities should be made to fit our lives.
We're going to build it from the ground up, with all the data we can round up, precinct
by precinct.
The Smart City.
We've got the ideas and the expertise, connecting research degrees and industries, turning big
ideas into realities.
We'll innovate and collaborate with business and government, the community and anyone that
wants to be a part of the unity, in creating tomorrow.
It's QUT, it's IFE, the Institute for Future Environments.
