For FIFTY YEARS scientists have known about global warming. This excerpt is from the well known educational documentary "Unchained Goddess" produced by Frank Capra for Bell Labs for their television program "The Bell Telephone Hour." It was so well made, that it went on to live a continued life in middle school science classrooms across the nation for decades.
Nearly half a century before Al Gore's "Inconvenient Truth," this film was made. But what does it reveal? That our scientists have known for over two generations about this danger, but our politicians and citizenry have chosen to ignore the dangerous implications of this fact until it really is too late to avoid the preventable consequences.
Perhaps we deserve our fate.

DIY Safe Hydrogen Storage
How to make graphitic carbon nitride from Urea and Table sugar in a Kiln. to 200C to dry and react at 550C.
Stores 10% by weight hydrogen. And needs 300C to release gas. I assume to capture gas as well.

Abstract
In this work, the Complex Fast Fourier Transform (CFFT) method is introduced to predict the roof temperature and heat gain in the tropical country of Singapore. The cost-effectiveness of cool paint and roof ventilation are evaluated through life-cycle analysis.
Cool paint and roof ventilation can provide annual cooling energy savings of 33-57 USD/m2 for the top-floor residential units. The payback period of cool paint is shorter than 2 months in unventilated roof and shorter than 6 months in ventilated roof. Both cool paint and roof ventilation are very energy-efficient and cost-effective in tropical climate.
