The first ingredient is materials and geometry, and that needs to be tightly coupled with the
energy
source.
And this is demonstrating that through random energy, we can build non-random shapes.
So we built a large rotating chamber, and people would come up and spin the chamber faster or slower, adding
energy
to the system and getting an intuitive understanding of how self-assembly works and how we could use this as a macroscale construction or manufacturing technique for products.
But it takes
energy
to store them in one place, and, thanks to our friend Albert Einstein, we know that
energy
and mass are related.
Plugging all those electrons and the
energy
it takes to hold them in the correct place for you to see the video, into that formula, we can figure out that one minute of YouTube video increases the mass of your computer by about 10 to the negative 19th grams.
That would be a waste of
energy
for a bird that doesn't know when it will get its next meal.
I've really tried to solve some big problems: counterterrorism, nuclear terrorism, and health care and diagnosing and treating cancer, but I started thinking about all these problems, and I realized that the really biggest problem we face, what all these other problems come down to, is energy, is electricity, the flow of electrons.
That's how much thermal
energy
the reactor's putting out to how much electricity it's producing.
So I really think that in the, say, 20 years it's going to take us to get fusion and make fusion a reality, this could be the source of
energy
that provides carbon-free electricity.
I think that I've designed this reactor here that can be an innovative source of energy, provide power for all kinds of neat scientific applications, and I'm really prepared to do this.
The
energy
that I'm able to talk to you today, while it was converted to chemical
energy
in my food, originally came from a nuclear reaction, and so there's something poetic about, in my opinion, perfecting nuclear fission and using it as a future source of innovative
energy.
And all the components are there which are now in common parlance, in our vocabulary, you know, 30-odd years later: wind energy, recycling, biomass, solar cells.
For example, if, in that Bucky-inspired phrase, we draw back and we look at planet Earth, and we take a kind of typical, industrialized society, then the
energy
consumed would be split between the buildings, 44 percent, transport, 34 percent, and industry.
If you looked at the buildings together with the associated transport, in other words, the transport of people, which is 26 percent, then 70 percent of the
energy
consumption is influenced by the way that our cites and infrastructure work together.
In other words, you take these comparable examples and the
energy
leap is enormous.
So basically, if you wanted to generalize, you can demonstrate that as the density increases along the bottom there, that the
energy
consumed reduces dramatically.
If you take China, and you just take Beijing, you can see on that traffic system, and the pollution associated with the consumption of
energy
as the cars expand at the price of the bicycles.
And particularly, how can it lead to the creation of buildings which consume less energy, create less pollution and are more socially responsible?
And a combination of devices here, the kind of heavy mass concrete of these book stacks, and the way in which that is enclosed by this skin, which enables the building to be ventilated, to consume dramatically less energy, and where it's really working with the forces of nature.
And you can measure the performance, in terms of
energy
consumption, of that building against a typical library.
And again, we can measure the reduction in terms of
energy
consumption.
Now, how about your household
energy
use?
A few
energy
geeks spread out across the room.
Harriet's paying attention to her
energy
use, and she is decidedly not an
energy
geek.
This is coal, the most common source of electricity on the planet, and there's enough
energy
in this coal to light this bulb for more than a year.
But unfortunately, between here and here, most of that
energy
is lost to things like transmission leakage and heat.
The bad news here is that, for every unit of
energy
we use, we waste nine.
That means there's good news, because for every unit of
energy
we save, we save the other nine.
So the question is, how can we get the people in this room and across the globe to start paying attention to the
energy
we're using, and start wasting less of it?
They had zero impact on
energy
consumption.
