The U.S. is currently seeing the effects of the first in real-time. The last major space weather event struck Earth in 1859. Smaller, but still significant, space weather events occur regularly.

Wearable electronics powered by the user's own body heat could help tackle the issue of how to storage energy.

Thanks to rapid computing developments in the last decade and the miniaturisation of electronic components, people can, for example, track their movements and monitor their health in real time by wearing tiny computers. Researchers are now looking at how best to power these devices by turning to the user's own body heat and working with garments, polka dots and know-how from the textile industry.
