I'm Roger Ely. And here at OSU
I'm an Associate Professor in the department of
Biological and Ecological Engineering.
Starting about seven or eight years ago,
about eight years ago, I wanted to get into
research dealing with sustainable energy, renewable energy.
And- so what we're doing now is what some people
call bio-solar hydrogen production.
Other people call it photo-biological hydrogen production.
But what that means is really that we work
with bacteria that use solar energy
to split water and make hydrogen.
Hydrogen is a very energy-rich compound.
It's about three times more energy-rich
on a pound basis- mass basis, than gasoline.
In general, we're working with organisms
called cyanobacteria.
And cyano is kind of like cyan the color,
you know a blue-green.
And the reason that we work with them is
that first of all they have a full complement
of photosynthetic capabilities. So they have
all of the photosynthetic enzymes that allow
them to carry out all of the functions of photosynthesis,
oxygenic photosynthesis, which means
they split water and make oxygen
Everything that we do is so dependent
on energy. And you look around you and
you know- this camera that's recording this,
if you were to actually look at
the amount of energy that's embodied in that camera
from the mining and the manufacturing of
whatever metals are there and whatever plastics
and etcetera, etcetera,
all the way to the marketing and getting it
to the store and buying it and all that.
There's a lot of energy that's there
that we don't think about.
And so I started think about issues
around the world and everything
came back to energy.
