The threat posed by climate change cannot be overstated, but even as warnings continue to pour in from scientists, conservationists, the United Nations and others, so engineers are working on possible solutions. Farming contributes approximately a third of greenhouse gas emissions, but thanks to creative engineering, it may be possible to reduce those emissions significantly.
NASA is currently the world leader when it comes to the latest in space travel technology, and their many years of experience and experimentation means that they have a deeper understanding of the difficulties of space travel than most.
In line with this, NASA has offered a large reward to anyone around the world that is able to offer some real progress on some of these ideas. Without enough time and the right investments, many of these ideas could change the way we handle our voyages into the dark void surrounding our planet.
