WEBVTT

00:00:01.333 --> 00:00:02.533
Welcome, everyone!

00:00:03.271 --> 00:00:06.210
What I'm going to do is,
I'm going to explain to you

00:00:06.234 --> 00:00:08.262
an extreme green concept

00:00:08.286 --> 00:00:11.254
that was developed
at NASA's Glenn Research Center

00:00:11.278 --> 00:00:13.256
in Cleveland, Ohio.

00:00:13.280 --> 00:00:15.686
But before I do that, we have to go over

00:00:15.710 --> 00:00:17.234
the definition of what green is,

00:00:17.247 --> 00:00:20.220
'cause a lot of us have a
different definition of it.

00:00:20.244 --> 00:00:22.213
Green. The product is created through

00:00:22.237 --> 00:00:24.676
environmentally and socially
conscious means.

00:00:24.700 --> 00:00:27.864
There's plenty of things that
are being called green now.

00:00:27.888 --> 00:00:29.476
What does it actually mean?

00:00:29.500 --> 00:00:33.119
We use three metrics to determine green.

00:00:33.143 --> 00:00:36.211
The first metric is: Is it sustainable?

00:00:36.235 --> 00:00:39.735
Which means, are you preserving
what you are doing for future use

00:00:39.759 --> 00:00:42.230
or for future generations?

00:00:42.254 --> 00:00:46.203
Is it alternative? Is it different
than what is being used today,

00:00:46.227 --> 00:00:49.008
or does it have a lower carbon footprint

00:00:49.032 --> 00:00:51.592
than what's used conventionally?

00:00:51.616 --> 00:00:54.427
And three: Is it renewable?

00:00:54.451 --> 00:00:58.183
Does it come from Earth's
natural replenishing resources,

00:00:58.207 --> 00:01:01.283
such as sun, wind and water?

NOTE Paragraph

00:01:01.307 --> 00:01:04.815
Now, my task at NASA is to develop

00:01:04.839 --> 00:01:08.011
the next generation of aviation fuels.

00:01:08.035 --> 00:01:10.840
Extreme green. Why aviation?

00:01:10.864 --> 00:01:14.197
The field of aviation uses
more fuel than just about

00:01:14.221 --> 00:01:19.213
every other combined. We
need to find an alternative.

00:01:19.237 --> 00:01:22.213
Also it's a national
aeronautics directive.

00:01:22.237 --> 00:01:24.881
One of the national aeronautics
goals is to develop

00:01:24.905 --> 00:01:27.577
the next generation of fuels, biofuels,

00:01:27.601 --> 00:01:31.287
using domestic and safe,
friendly resources.

00:01:31.311 --> 00:01:34.155
Now, combating that challenge

00:01:34.179 --> 00:01:37.045
we have to also meet
the big three metric —

00:01:37.069 --> 00:01:40.858
Actually, extreme green
for us is all three together;

00:01:40.882 --> 00:01:43.644
that's why you see the plus
there. I was told to say that.

00:01:43.668 --> 00:01:48.245
So it has to be the big three at
GRC. That's another metric.

00:01:48.269 --> 00:01:54.196
Ninety-seven percent of the
world's water is saltwater.

00:01:54.220 --> 00:01:58.206
How about we use that?
Combine that with number three.

00:01:58.230 --> 00:02:01.238
Do not use arable land.

00:02:01.262 --> 00:02:03.453
Because crops are already
growing on that land

00:02:03.477 --> 00:02:06.215
that's very scarce around the world.

00:02:06.239 --> 00:02:09.222
Number two: Don't compete with food crops.

00:02:09.246 --> 00:02:13.639
That's already a well established
entity, they don't need another entry.

00:02:13.663 --> 00:02:17.587
And lastly the most precious
resource we have on this Earth

00:02:17.611 --> 00:02:22.247
is fresh water. Don't use fresh water.

00:02:22.271 --> 00:02:25.218
If 97.5 percent
of the world's water is saltwater,

00:02:25.242 --> 00:02:28.495
2.5 percent is fresh water.
Less than a half percent

00:02:28.519 --> 00:02:30.256
of that is accessible for human use.

00:02:30.280 --> 00:02:34.217
But 60 percent of the population
lives within that one percent.

NOTE Paragraph

00:02:34.241 --> 00:02:39.209
So, combating my problem was,
now I have to be extreme green

00:02:39.233 --> 00:02:41.457
and meet the big three.
Ladies and gentlemen,

00:02:41.481 --> 00:02:45.203
welcome to the GreenLab Research Facility.

00:02:45.227 --> 00:02:48.138
This is a facility dedicated
to the next generation

00:02:48.162 --> 00:02:51.283
of aviation fuels using halophytes.

00:02:51.307 --> 00:02:54.261
A halophyte is a salt-tolerating plant.

00:02:54.285 --> 00:02:58.289
Most plants don't like salt,
but halophytes tolerate salt.

00:02:58.313 --> 00:03:01.284
We also are using weeds

00:03:01.308 --> 00:03:04.215
and we are also using algae.

00:03:04.239 --> 00:03:06.239
The good thing about our lab is, we've had

00:03:06.263 --> 00:03:09.216
3,600 visitors in the last two years.

00:03:09.240 --> 00:03:11.218
Why do you think that's so?

00:03:11.242 --> 00:03:15.224
Because we are on to something special.

NOTE Paragraph

00:03:15.248 --> 00:03:17.793
So, in the lower you see
the GreenLab obviously,

00:03:17.817 --> 00:03:20.245
and on the right hand
side you'll see algae.

00:03:20.269 --> 00:03:23.198
If you are into the business
of the next generation

00:03:23.222 --> 00:03:25.518
of aviation fuels, algae
is a viable option,

00:03:25.542 --> 00:03:27.209
there's a lot of funding right now,

00:03:27.221 --> 00:03:29.218
and we have an algae to fuels program.

00:03:29.242 --> 00:03:31.218
There's two types of algae growing.

00:03:31.242 --> 00:03:34.211
One is a closed photobioreactor
that you see here,

00:03:34.235 --> 00:03:38.232
and what you see on the other
side is our species —

00:03:38.256 --> 00:03:42.202
we are currently using a species
called Scenedesmus dimorphus.

00:03:42.226 --> 00:03:46.508
Our job at NASA is to take the
experimental and computational

00:03:46.532 --> 00:03:51.203
and make a better mixing for
the closed photobioreactors.

00:03:51.227 --> 00:03:53.608
Now the problems with closed
photobioreactors are:

00:03:53.632 --> 00:03:55.971
They are quite expensive,
they are automated,

00:03:55.995 --> 00:03:58.999
and it's very difficult
to get them in large scale.

00:03:59.023 --> 00:04:00.690
So on large scale what do they use?

00:04:00.714 --> 00:04:04.117
We use open pond systems.
Now, around the world

00:04:04.141 --> 00:04:07.638
they are growing algae,
with this racetrack design

00:04:07.662 --> 00:04:10.087
that you see here. Looks like an oval with

00:04:10.111 --> 00:04:12.224
a paddle wheel and mixes really well,

00:04:12.248 --> 00:04:16.282
but when it gets around the last turn,
which I call turn four — it's stagnant.

00:04:16.306 --> 00:04:18.272
We actually have a solution for that.

00:04:18.296 --> 00:04:21.236
In the GreenLab in our open pond system

00:04:21.260 --> 00:04:24.251
we use something that happens
in nature: waves.

00:04:24.275 --> 00:04:27.943
We actually use wave technology
on our open pond systems.

00:04:27.967 --> 00:04:32.627
We have 95 percent mixing
and our lipid content is higher

00:04:32.651 --> 00:04:35.245
than a closed photobioreactor system,

00:04:35.269 --> 00:04:37.226
which we think is significant.

NOTE Paragraph

00:04:37.250 --> 00:04:41.258
There is a drawback to algae,
however: It's very expensive.

00:04:41.282 --> 00:04:46.361
Is there a way to produce
algae inexpensively?

00:04:46.385 --> 00:04:48.222
And the answer is: yes.

00:04:48.246 --> 00:04:51.245
We do the same thing
we do with halophytes,

00:04:51.269 --> 00:04:55.200
and that is: climatic adaptation.

00:04:55.224 --> 00:04:58.012
In our GreenLab we have
six primary ecosystems

00:04:58.036 --> 00:05:01.983
that range from freshwater
all the way to saltwater.

00:05:02.007 --> 00:05:05.742
What we do: We take a potential
species, we start at freshwater,

00:05:05.766 --> 00:05:08.470
we add a little bit more salt,
when the second tank here

00:05:08.494 --> 00:05:10.602
will be the same ecosystem as Brazil —

00:05:10.626 --> 00:05:13.698
right next to the sugar cane
fields you can have our plants —

00:05:13.722 --> 00:05:17.941
the next tank represents Africa,
the next tank represents Arizona,

00:05:17.965 --> 00:05:20.252
the next tank represents Florida,

00:05:20.276 --> 00:05:24.115
and the next tank represents
California or the open ocean.

00:05:24.139 --> 00:05:28.210
What we are trying to do is to
come up with a single species

00:05:28.234 --> 00:05:34.215
that can survive anywhere in the
world, where there's barren desert.

00:05:34.239 --> 00:05:36.253
We are being very successful so far.

NOTE Paragraph

00:05:36.277 --> 00:05:38.897
Now, here's one of the problems.

00:05:38.921 --> 00:05:44.624
If you are a farmer, you need five things
to be successful: You need seeds,

00:05:44.648 --> 00:05:48.239
you need soil, you need
water and you need sun,

00:05:48.263 --> 00:05:51.809
and the last thing that you
need is fertilizer.

00:05:51.833 --> 00:05:55.364
Most people use chemical fertilizers.
But guess what?

00:05:55.388 --> 00:05:58.064
We do not use chemical fertilizer.

00:05:58.088 --> 00:06:03.219
Wait a second! I just saw lots of greenery
in your GreenLab. You have to use fertilizer.

00:06:03.243 --> 00:06:07.424
Believe it or not, in our analysis
of our saltwater ecosystems

00:06:07.448 --> 00:06:11.224
80 percent of what we need
are in these tanks themselves.

00:06:11.248 --> 00:06:15.223
The 20 percent that's missing
is nitrogen and phosphorous.

00:06:15.247 --> 00:06:17.279
We have a natural solution: fish.

00:06:17.303 --> 00:06:21.167
No we don't cut up the fish
and put them in there.

00:06:21.191 --> 00:06:25.050
Fish waste is what we use.
As a matter of fact

00:06:25.074 --> 00:06:29.215
we use freshwater mollies, that we've
used our climatic adaptation technique

00:06:29.239 --> 00:06:32.237
from freshwater all the way to seawater.

00:06:32.261 --> 00:06:39.233
Freshwater mollies: cheap,
they love to make babies,

00:06:39.257 --> 00:06:41.042
and they love to go to the bathroom.

00:06:41.066 --> 00:06:43.197
And the more they go to the
bathroom, the more fertilizer we get,

00:06:43.221 --> 00:06:45.736
the better off we are, believe it or not.

00:06:45.760 --> 00:06:51.001
It should be noted that we use
sand as our soil,

00:06:51.025 --> 00:06:55.226
regular beach sand. Fossilized coral.

NOTE Paragraph

00:06:55.250 --> 00:06:59.197
So a lot of people ask me,
"How did you get started?"

00:06:59.221 --> 00:07:04.202
Well, we got started in what we
call the indoor biofuels lab.

00:07:04.226 --> 00:07:08.608
It's a seedling lab. We have 26
different species of halophytes,

00:07:08.632 --> 00:07:11.880
and five are winners. What we do here is —

00:07:11.904 --> 00:07:14.705
actually it should be called
a death lab, 'cause we try to

00:07:14.729 --> 00:07:17.294
kill the seedlings, make them rough —

00:07:17.318 --> 00:07:19.614
and then we come to the GreenLab.

00:07:19.638 --> 00:07:21.372
What you see in the lower corner

00:07:21.396 --> 00:07:23.560
is a wastewater treatment plant experiment

00:07:23.584 --> 00:07:27.253
that we are growing, a macro-algae
that I'll talk about in a minute.

00:07:27.277 --> 00:07:31.239
And lastly, it's me actually working
in the lab to prove to you I do work,

00:07:31.263 --> 00:07:34.971
I don't just talk about what I do.

00:07:34.995 --> 00:07:38.201
Here's the plant species.
Salicornia virginica.

00:07:38.225 --> 00:07:41.760
It's a wonderful plant. I love that plant.

00:07:41.784 --> 00:07:45.226
Everywhere we go we see it. It's
all over the place, from Maine

00:07:45.250 --> 00:07:48.237
all the way to California.
We love that plant.

00:07:48.261 --> 00:07:53.202
Second is Salicornia bigelovii. Very
difficult to get around the world.

00:07:53.226 --> 00:07:55.369
It is the highest lipid
content that we have,

00:07:55.393 --> 00:07:59.238
but it has a shortcoming: It's short.

00:07:59.262 --> 00:08:04.359
Now you take europaea, which is the
largest or the tallest plant that we have.

00:08:04.383 --> 00:08:06.277
And what we are trying to do

00:08:06.301 --> 00:08:10.658
with natural selection or adaptive
biology — combine all three

00:08:10.682 --> 00:08:14.774
to make a high-growth, high-lipid plant.

00:08:14.798 --> 00:08:22.038
Next, when a hurricane decimated the
Delaware Bay — soybean fields gone —

00:08:22.062 --> 00:08:24.902
we came up with an idea:
Can you have a plant

00:08:24.926 --> 00:08:30.213
that has a land reclamation positive
in Delaware? And the answer is yes.

00:08:30.237 --> 00:08:34.187
It's called seashore mallow.
Kosteletzkya virginica —

00:08:34.211 --> 00:08:37.205
say that five times fast if you can.

00:08:37.229 --> 00:08:44.793
This is a 100 percent usable plant. The
seeds: biofuels. The rest: cattle feed.

00:08:44.817 --> 00:08:48.232
It's there for 10 years;
it's working very well.

00:08:48.256 --> 00:08:51.559
Now we get to Chaetomorpha.

00:08:51.583 --> 00:08:54.781
This is a macro-algae that loves

00:08:54.805 --> 00:08:57.329
excess nutrients. If you
are in the aquarium industry

00:08:57.353 --> 00:09:00.014
you know we use it
to clean up dirty tanks.

00:09:00.038 --> 00:09:04.225
This species is so significant to us.

00:09:04.249 --> 00:09:08.196
The properties are very close to plastic.

00:09:08.220 --> 00:09:13.574
We are trying right now to convert
this macro-algae into a bioplastic.

00:09:13.598 --> 00:09:18.247
If we are successful, we will
revolutionize the plastics industry.

NOTE Paragraph

00:09:18.271 --> 00:09:21.769
So, we have a seed to fuel program.

00:09:21.793 --> 00:09:24.726
We have to do something with
this biomass that we have.

00:09:24.750 --> 00:09:29.235
And so we do G.C. extraction, lipid
optimization, so on and so forth,

00:09:29.259 --> 00:09:32.922
because our goal really is to come up with

00:09:32.946 --> 00:09:36.832
the next generation of aviation fuels,
aviation specifics, so on and so forth.

00:09:36.856 --> 00:09:41.252
So far we talked about water and fuel,

00:09:41.276 --> 00:09:48.196
but along the way we found out
something interesting about Salicornia:

00:09:48.220 --> 00:09:51.882
It's a food product.

00:09:51.906 --> 00:09:54.695
So we talk about ideas
worth spreading, right?

00:09:54.719 --> 00:10:01.549
How about this: In sub-Saharan
Africa, next to the sea, saltwater,

00:10:01.573 --> 00:10:06.408
barren desert,
how about we take that plant,

00:10:06.432 --> 00:10:11.240
plant it, half use for food,
half use for fuel.

00:10:11.264 --> 00:10:15.041
We can make that happen, inexpensively.

00:10:15.065 --> 00:10:17.739
You can see
there's a greenhouse in Germany

00:10:17.763 --> 00:10:20.203
that sells it as a health food product.

00:10:20.227 --> 00:10:25.429
This is harvested, and in the middle here
is a shrimp dish, and it's being pickled.

00:10:25.453 --> 00:10:30.042
So I have to tell you a joke.
Salicornia is known as sea beans,

00:10:30.066 --> 00:10:33.515
saltwater asparagus and pickle weed.

00:10:33.539 --> 00:10:36.246
So we are pickling pickle
weed in the middle.

00:10:36.270 --> 00:10:39.048
Oh, I thought it was funny. (Laughter)

00:10:39.072 --> 00:10:42.421
And at the bottom is seaman's mustard.
It does make sense,

00:10:42.445 --> 00:10:44.808
this is a logical snack. You have mustard,

00:10:44.832 --> 00:10:47.956
you are a seaman, you see the
halophyte, you mix it together,

00:10:47.980 --> 00:10:50.218
it's a great snack with some crackers.

00:10:50.242 --> 00:10:57.218
And last, garlic with Salicornia,
which is what I like.

00:10:57.242 --> 00:11:02.193
So, water, fuel and food.

NOTE Paragraph

00:11:02.217 --> 00:11:05.744
None of this is possible
without the GreenLab team.

00:11:05.768 --> 00:11:10.725
Just like the Miami Heat has the big
three, we have the big three at NASA GRC.

00:11:10.749 --> 00:11:16.204
That's myself, professor Bob Hendricks,
our fearless leader, and Dr. Arnon Chait.

00:11:16.228 --> 00:11:20.733
The backbone of the GreenLab is students.

00:11:20.757 --> 00:11:24.648
Over the last two years
we've had 35 different students

00:11:24.672 --> 00:11:27.803
from around the world working at GreenLab.

00:11:27.827 --> 00:11:32.212
As a matter fact my division chief says
a lot, "You have a green university."

00:11:32.236 --> 00:11:34.747
I say, "I'm okay with that,
'cause we are nurturing

00:11:34.771 --> 00:11:39.771
the next generation of extreme
green thinkers, which is significant."

NOTE Paragraph

00:11:39.795 --> 00:11:45.092
So, in first summary I presented
to you what we think

00:11:45.116 --> 00:11:51.219
is a global solution
for food, fuel and water.

00:11:51.243 --> 00:11:54.213
There's something missing to be complete.

00:11:54.237 --> 00:11:59.004
Clearly we use electricity.
We have a solution for you —

00:11:59.028 --> 00:12:02.253
We're using clean energy sources here.

00:12:02.277 --> 00:12:06.674
So, we have two wind turbines
connected to the GreenLab,

00:12:06.698 --> 00:12:10.201
we have four or five more
hopefully coming soon.

00:12:10.225 --> 00:12:13.811
We are also using something
that is quite interesting —

00:12:13.835 --> 00:12:18.434
there is a solar array field at
NASA's Glenn Research Center,

00:12:18.458 --> 00:12:21.576
hasn't been used for 15 years.

00:12:21.600 --> 00:12:24.339
Along with some of my electrical
engineering colleagues,

00:12:24.363 --> 00:12:26.482
we realized that they are still viable,

00:12:26.506 --> 00:12:29.238
so we are refurbishing them right now.

00:12:29.262 --> 00:12:34.274
In about 30 days or so they'll be
connected to the GreenLab.

NOTE Paragraph

00:12:34.298 --> 00:12:37.200
And the reason why you see
red, red and yellow, is

00:12:37.224 --> 00:12:40.467
a lot of people think NASA employees
don't work on Saturday —

00:12:40.491 --> 00:12:43.385
This is a picture taken on Saturday.

00:12:43.409 --> 00:12:48.010
There are no cars around, but you see my truck
in yellow. I work on Saturday. (Laughter)

00:12:48.034 --> 00:12:49.939
This is a proof to you that I'm working.

00:12:49.963 --> 00:12:53.743
'Cause we do what it takes to get the
job done, most people know that.

00:12:53.767 --> 00:12:56.621
Here's a concept with this:

00:12:56.645 --> 00:13:02.177
We are using the GreenLab
for a micro-grid test bed

00:13:02.201 --> 00:13:06.215
for the smart grid concept in Ohio.

00:13:06.239 --> 00:13:12.147
We have the ability to do that,
and I think it's going to work.

00:13:12.171 --> 00:13:17.240
So, GreenLab Research Facility.

00:13:17.264 --> 00:13:22.263
A self-sustainable renewable energy
ecosystem was presented today.

00:13:22.287 --> 00:13:28.210
We really, really hope this
concept catches on worldwide.

00:13:28.234 --> 00:13:37.260
We think we have a solution for food,
water, fuel and now energy. Complete.

00:13:37.284 --> 00:13:43.385
It's extreme green, it's sustainable,
alternative and renewable

00:13:43.409 --> 00:13:47.223
and it meets the big three at GRC:

00:13:47.247 --> 00:13:52.214
Don't use arable land, don't
compete with food crops,

00:13:52.238 --> 00:13:55.276
and most of all, don't use fresh water.

NOTE Paragraph

00:13:55.300 --> 00:14:00.250
So I get a lot of questions about,
"What are you doing in that lab?"

00:14:00.274 --> 00:14:06.003
And I usually say, "None of your business,
that's what I'm doing in the lab." (Laughter)

00:14:06.027 --> 00:14:09.546
And believe it or not, my number one goal

00:14:09.570 --> 00:14:12.256
for working on this project is

00:14:12.280 --> 00:14:17.231
I want to help save the world.
