AFO Fire Ball, ABC Fire Extinguisher, Fire Suppression Device, Fire Safety Product With Sign - - Amazon.com
Interesting, a ball of fire extinguisher. It melts/expands over a fire, so stick it over something that might catch fire and it will effectively snuff itself out, without some fancy halon system.

The water footprint of water conservation using shade balls in California | Nature Sustainability
So reservoir shade balls might be a net negative unless they stay floating in the lake for a while (say 3 years of drought)

Macroscale superlubricity enabled by graphene nanoscroll formation
So right now this only works with amorphous diamond surfaces, but couple this with that diamond bearing coating that was recently announced, and you might have something good here.

Coo Space CO.,LTD.
Traditional ball bearings have some sort of cage to prevent coincidental impact and friction against adjacent balls, but the separation cage introduces additional friction. These guys claim they can get better performance, by eliminating the cage, and introducing a divot in the ball bearing race, which causes slightly uneven movement which somehow prevents adjacent bearings from impacting each other.

Research of Graphene-reinforced Aluminum Matrix Nanocomposites
Seems like if the powder grind/mix is well done, you get pretty awesome graphene nanoflake reinforced aluminum composites. Apparently they got over a previous issue, where CNT's in an aluminum matrix turned into aluminum carbide, lowering materials properties.

NEC puts household carbon footprint data online ::: Pink Tentacle
A smart little tie-up between a consumer electronics firm and an ISP to get people to buy into a green power monitoring program. This is an interesting strategic move, trying to gain control of power statistical data of ISP customers, potentially as and end run around the electric utilities, so the utilities are forced to pay the data gatekeepers, the ISP, with a cut for the monitoring hardware maker. And since japanese can be utter sheep when someone trots out a green label, there is the potential for significant traction, especially if the ISP is willing to take a loss on the hardware in expectation of revenue from monthly subscribers plus data delivery to users of such data. All the more reason there needs to be open standards and zero barriers to data usage by the original data creators, the end consumer, or else you will have a fantastic data lock-in monopoly.
