Aluminum Oxide has been around since the late 1800's. Artificial Sapphire is difficult to manufacture. Takes a lot of time and energy to create the boule and cut it. Although it sounds cool, it is not as flexible as Gorilla Glass so it has some disadvantages other than being more expensive. The military use it for bullet proof windows. Apple uses it for their touch 'button'. Sapphire has a higher dielectric constant so it is better for capacitive touch technologies.

Previous CO2 maps

The latest NASA satellite (OCO2) to measure CO2 shows results that are completely different from previous models & measurements. The satellite images prove our previous understanding of CO2 to be wrong. In fact if you average the 387 to 402.5 regions and notice that the tiny regions of high CO2 concentration are not in industrialized areas but in rain forest areas I would guess the current global concentration to be around 394ppm.
Saying that, 400ppm is 0.04% which is barely a trace gas. You wonder how plants survive at all. Once our oily fossil fuels run out we might even be as high as 460ppm which is still nothing. CO2 levels have been as high as 6000ppm when life flourished on earth.
A pending disaster is what'll happen when we run out of CO2 after fossil fuels are all used up. If plants starve so will we. Wasting trillions of $ trying to keep CO2 levels under an arbitrary level or 'the same' every year is futile. I'd worry more about industrial pollutions. Man made CO2 is not controlling global temperatures.

"Stanene"
Well, it sounds more like an ingredient for an ED medication. Viagra... now with 10% more Stanene. It took all my energy getting my hopes up for graphene... I can't handle another material at the moment.
Funny about tinfoil... should be called Alfoil... but it sounds too much like awful. lol. Do people really still call aluminum foil as tin foil? I remember calling it that decades ago. It's not actually written on packaging anywhere is it?
