Nothing beats a cold beer, and few things are worse than a cold beer gone warm. The latter might not ever happen again:
Beer bottles that use solar power to keep their precious contents cool in the height of summer could be a welcome fringe benefit of thin-film technology currently under development.
The material being developed by researchers at the US Rensselaer Polytechnic Institute sticks solar cells and heat pumps onto surfaces, and could ultimately turn walls, windows and even beer bottles into climate control systems.
