is someone shooting at us? :)


I'm the enemy, 'cause I like to think, I like to read. I'm into freedom of speech, and freedom of choice. I'm the kinda guy that likes to sit in a greasy spoon and wonder, "Gee, should I have the T-bone steak or the jumbo rack of barbecue ribs with the side-order of gravy fries?" I want high cholesterol! I wanna eat bacon, and butter, and buckets of cheese, okay?! I wanna smoke a Cuban cigar the size of Cincinnati in the non-smoking section! I wanna run naked through the street, with green Jell-O all over my body, reading Playboy magazine. Why? Because I suddenly may feel the need to, okay, pal? I've SEEN the future. Do you know what it is? It's a 47-year-old virgin sitting around in his beige pajamas, drinking a banana-broccoli shake, singing "I'm an Oscar Meyer Wiene"

Oof, could you imagine technology behind a weapon powerful enough to push stars.

It's a sign Syfy should bring back the show Dark Matter :)

I loved that show and remember being surprised it got canceled but Killjoys survived.

Clearly someone has a Death Star. 😉

https://www.newscientist.com/article/2204442-high-tech-wood-could-keep-homes-cool-by-reflecting-the-suns-rays/

Liangbing Hu at the University of Maryland and his colleagues created the material by removing the lignin—a component of the cell walls in trees—from natural wood using hydrogen peroxide.

The remaining wood is mostly made of cellulose, another component of plant cell wall. Cellulose reflects visible light and only absorbs very low levels of near-infrared light. This means the cooling wood reflects most of the components of sunlight right back to the environment. As a result, a building made from this material would transmit barely any heat indoors.

The team also found that the material can absorb heat produced indoors, which is emitted at a different wavelength range to sunlight. During cooler nights, the wood helps release the heat outside, making it useful day and night.

Hu says the cooling wood is very dense and has a tensile strength of around 404 megapascals, making it 8.7 times stronger than natural wood and comparable to metal structure materials including steel.
