How this ex-pool boy is changing water | Ravi Kurani | TEDxSalinas


thousands of people died in London in

1854 cholera was the killer cholera is a

disease that kills within days so there

was this guy John Snow who walked around

the Soho district of London knocking

from door to door to door and he asked

has there been a death in the family and

he got an answer why yes my mother died

yesterday he went to the next house and

he asked ma’am has there been a death in

the family and he got an answer no not

here

but up the street at 64 Lexington a

little girl died two days ago he took

all these deaths and he put them up on a

map these little black lines here show

us what he actually saw I’ve exaggerated

this data so you can actually see it a

little better on this screen John snow

had a sneaking suspicion that the water

pump was the reason for the transport of

cholera do you guys notice anything

particular about this data when I layer

over where the pumps were in the city it

becomes very obvious at the corner of

broad and Lexington this pump was to

blame John snow figured this out and

they call him the father of modern day

epidemiology the study of how health and

disease moves throughout a city now what

John snow did is great I think it’s

awesome however it is not scalable right

think about how many pumps there are

around the world how many wells there

are and how many people are affected by

disease and illness from this water you

need to hire millions if not billions of

John snows and they would need to knock

on all of these doors every single day

he would need to ask is there a disease

is there an illness

has there been a death water testing

today is reactive we need to make it

proactive we’re trying to find solutions

for water but we don’t understand what

the problem actually is how can you find

a solution if you don’t understand the

problem space I’ve made it my life’s

goal to figure out what this problem is

let’s have a conversation about how we

can hack water and what the future of

water is about how we can build millions

of John snows and put them around the

world I used to work at a venture

capital fund in India think like Shark

Tank but India without the Mark Cuban

and the really cool thing about this

venture capital fund is we only gave

money to companies who were building

products that focused on people our

populations that earned less than $2 a

day and one really cool thing that I saw

about this company was we saw a ton of

business plans that came through the

door there was one in particular that

sticks out it was this company in South

India that was actually developing a

water filter something that purifies our

water however the only issue is is it

was way too expensive it was not

accessible to the population it was

targeting and what’s even worse is when

we went down to this geography that they

were looking to do their first

deployment in turns out there is a

simple five cent solution that was a

chlorine pill now I want to get one

thing straight I am NOT for simple

solutions I do believe in long-term

Social Development and let’s figure out

progress on how we can actually

implement it properly however if your

goal is to get people out of hospital

beds let’s do the short term solution

first figure out what the problem is and

then build a solution around that this

got me really interested in water and so

I started doing a ton of research and I

figured out here in the u.s. about 70%

of our water is primarily used for

energy generation and agriculture the

rest of it is used for stuff that we’re

used to like taking a shower wash

our hands and drinking water but one

really interesting thing that I learned

is that water is different for each

application you use it for and what I

mean by this is for agriculture or for

drinking water or for your swimming pool

right let’s take a swimming pool for

example if you were to go to your

swimming pool you would need to measure

the water now you go to your backyard

and you’d say the chlorine is low this

is how you understand what the data is

and after you understand that the

chlorine is low let’s say it needs to be

up to five parts per million or ppm and

you’re down to one you add chlorine you

fix the water this loop is different for

everything right so you wouldn’t take

the swimming pool water and put it into

your tap to drink you wouldn’t take the

swimming pool water and let’s say for

example you’re brewing beer right water

is a really big part of brewing beer you

don’t want your swimming pool water to

brew that beer and the really cool thing

that I figured out is that there’s a

bunch of these little little small loops

everywhere you go and after looking at

it there’s one thing that I really want

to get across is that water is different

it comes in different shapes and

different flavors and different sizes

you can think about it as like a big

control board right you have all these

levers triggers and switches and if you

have a swimming pool you’re going to

increase the chlorine if you have an

agriculture you’re going to increase the

nitrates you may add levers you may

subtract levers

there’s picture over years of the

Olympics in Rio the green pool on the

side it doesn’t look so good right it

was a loop it was a measure understand

fixed loop that was not managed properly

the chlorine was low which ended up

causing algae to grow thus causing a

green pool all this talk about pools by

the way I actually used to be a pool boy

down down in Southern California my

parents used to own a chain of pool and

spa supply stores and by the way I

looked absolutely amazing and semuc

little short you know lifeguard red

shorts

I still remember riding around the

pickup truck we would go from house to

house like a pool boy does and they

would take a test of the water take the

little four drops if any of you have

ever tested a pool before you look at

the pH you look at the chlorine I would

figure out this is what it needs and you

would put the chlorine in to give a safe

environment for these homeowners to

swimmin fast forward a few years my

company up in San Francisco we had this

idea why don’t we automate this process

why don’t we build a robot in a sense of

John snow that can automatically measure

the pool chemistry tell you what your

chemicals are and then you go ahead and

put it in and we built just that we have

a little floating robot Wi-Fi connected

have your app tells you what chemicals

to put in and if you don’t have them we

use your Hamazon primer credit card get

it delivered to your house the next day

and we looked at and we said there is

more to water than just pools right

these loops exist everywhere how do we

take this this robot that we built and

deployed around the world so we don’t

have problems like Jon Snow did in

London right how do we how do we get

when we started looking at this we

realized that because of these little

measure understand fixed loops you need

to have a library of understanding of if

this water is going to be used for a

swimming pool you need to put chlorine

here’s the equations that go with that

if you need to use this water for

agriculture you need to put more

nitrates here’s the equation that goes

with that what you end up building is

this library or this instruction book of

all these little mini instructions of

how you’re going to use the water that’s

coming in for the purpose you need to

use it for just like the human genome

what if we had built the water genome

and when we ask this question we started

looking at where water is a problem

around the world is it just John snow is

it this isolated incident in London or

does it happen around the world and so

there’s three stories I want to talk

about today of how this genome and this

robotics platform can change the way

that we look at water the first let’s go

to Flint Michigan in Flint they move the

water source to the Flint River

and this chemical cocktail inside of

this new water source was slightly

different than what they were actually

getting their water from as this water

percolated through the piping and ended

up into the houses turn on your tap pour

yourself a glass of water what ended up

happening is this cocktail activated

lead in the pipes in a particular area

you now have lead in your water

thousands of children have unsafe levels

of lead in them right now by the way

this is in 2012 not in 1854 second place

I want to take you to is Kenya the World

Health Organisation says that water and

water related diseases are the largest

killer in the world outside of wars

outside of terrorism waterborne

illnesses are a serious thing and people

travel miles to go get their water right

what if we could take this robotics

platform with the water genome and

deploy them at a well in say Kenya or in

Nigeria or in India or heck hey here in

Flint what if the thing measured the

chemistry at the well and we sent a text

message to the to the village head we

said hey well number 364 has an issue do

not drink from that well better yet we

sent the message to a nonprofit that is

maybe managing that well this well needs

more chemicals now I take you here close

to home in the Salinas Valley

water is a lifeblood for people here in

the valley and for any agrarian

community I was actually talking to a

daughter of a farmer the other day and I

want for one second all of us to

abstract ourselves of what we think

water is take yourself away from the

shower from the tap from the swimming

pool water pays this girl is ballerina

classes it pays for her college tuition

now imagine what the drought did to the

Parma’s here and as this drought

affected the farmers in the valley they

had to dig deeper and deeper and deeper

underground in search for water

to grow so need to feed the us and as

the water came out they had to over

fertilize right they have to make up for

the nutrients in the well and as they

over fertilize they planted the crops

this water ended up going into runoff

and now they’ve over fertilized this

water that’s going back into the

groundwater they’re polluting these

ground wells what if we could take this

robotics platform coupled with the

genome project put it at the input water

source we know what the water chemistry

is coming out hey mr. and mrs. farmer

add this particular fertilizer and after

it comes out for the runoff

let’s take a look at it if it’s too

polluted to go into the ground we’ll

stop it and put it somewhere else

everything I said just touches the tip

of the iceberg we need a better

understanding of water because we cannot

live without it the next time you open

up your tap just understand when you

look at that glass of water being filled

up water is more than just water join

the revolution there’s plenty of room

for all of us thank you [Applause]
