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)

This video is not a paid endorsement and I receive no

compensation for making this video.

All product links in the description below are affiliate

links and I may receive commissions if you purchase

products from these links.

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.
