DNA Will Be Construction Material of the Future

Church: Oh, life science will co-opt almost every other field of manufacturing. It’s not limited to agriculture and medicine. We can even use biology in ways that biology never has evolved to be used. DNA molecules for example could be used as three-dimensional scaffolding for inorganic materials, and this with atomic precision. You can design almost any structure you want with a computer, then you push a button — and there it is, built-in DNA.

SPIEGEL: DNA as the building material of the future?

Church: Exactly. And it’s amazing. Biology is good at making things that are really precise. Take trees for example. Trees are extremely complicated, at least on a molecular basis. However, they are so cheap, that we burn them or convert them into tables. Trees cost about $50 a ton. This means that you can make things that are nearly atomically precise for five cents a kilo.

SPIEGEL: You are seriously proposing to build all kinds of machines — cars, computers or coffee machines — out of DNA?

Church: I think it is very likely that this is possible. In fact, computers made of DNA will be better than the current computers, because they will have even smaller processors and be more energy efficient.

SPIEGEL: Let’s go through a couple of different applications of synthetic biology. How long will it take, for example, until we can fill our tanks with fuel that has been produced using synthentic microbes?

Church: The fact is that we already have organisms that can produce fuel compatible with current car engines. These organisms convert carbon dioxide and light into fuels by basically using photosynthesis.

SPIEGEL: And they do so in an economically acceptable way?

Church: If you consider $1.30 a gallon for fuel a good number, then yeah. And the price will go down. Most of these systems are at least a factor of five away from theoretical limits, maybe even a factor of 10.
