Casual Friday – Fotões viajam sempre sem bagagem
A photon checks into a hotel and is asked if he needs any help with his luggage. He says, “No, I’m traveling light.”
Um fotão entra num hotel e o empregado pergunta-lhe se quer ajuda com a bagagem. O fotão diz, “Não, eu viajo com a luz (light = luz /leve)

Hotel California: You can check out anytime you like, but you can never leave…
https://en.wikipedia.org/wiki/Hotel_California
The lyrics weave a surrealistic tale in which a weary traveler checks into a luxury hotel. The hotel at first appears inviting and tempting, but it turns out to be a nightmarish place where “you can check out anytime you like, but you can never leave”. The song is an allegory about hedonism, self-destruction, and greed in the music industry of the late 1970s.

Bem…
Gosto muito mais do “Photon Hotel”: After you check in, you actually become a lot more focused…

The initial globe design harvested up to 70% more solar energy than photovoltaic panels by using dual axis tracking. The sphere can be used to harvest sunlight for electricity or thermal energy, it can be fully integrated into the walls or ceilings of a building, and it suffers no weather impact. And, because it’s basically just a big crystal ball, it guarantees at least 99 percent transparency.
The solar sphere was a finalist in the World Technology Network Award 2013, which gave the Rawlemon team motivation to keep investigating, and now they’ve produced a second iteration, the Betaray, that’s even more polished than the last.
The Betaray is designed to concentrate diffuse light and generate a powerful beam of solar energy.
The Betaray can harness solar energy from the sun, the moon, or even the gray sky of a cloudy day, whereas conventional PV collectors need 4 times more incoming light before they start producing power.
