A graduate student Julian Melchiorri has
created a biological leaf. That has the ability to absorb water and carbon
dioxide to produce oxygen just like a plant. Julian did this by suspending
chloroplasts in a mixture made out of silk protein. He believed it can be used
for several things but the most incredible one is the thought that it could be
used for long distance space travel. Plants do not grow in space, but this
synthetic material can be used to produce oxygen in a hostile environment. The
silk Leaf is composed of chloroplasts suspended in silk proteins, for
the express purpose of long-distance space travel.
He says; plants don't grow in zero gravity.
Therefore; "NASA is researching diverse ways to create oxygen for
long-distance space journeys to let us live in space. This material could allow
us to explore space much further than we can now. This incredible finished
product functions like a plant in the sense that it is biological and produces
oxygen, but its synthetic packaging makes it more likely to be able to survive
in extraterrestrial environments.
Interestingly just like a real plant, it only requires light
and water to survive and photosynthesize:
Because Silk Leaf is the first man-made biological leaf and it is very
light, low energy-consuming, entirely biological. Therefore; it is really very
convenient and can extend even further, as making lamps out of Silk Leaf kills
two birds with one stone. My idea was to increase the efficiency of nature in a
man-made environment. I created some lighting out of this material, using the light
to illuminate the house but at the same time to create oxygen for us.
