+ - How About A Spherical Solar Collector ?-> 5

Submitted by Applehu Akbar
Applehu Akbar (2968043) writes "German architect André Broessel claims to have invented a solar collector that is far more efficient than today's flat panels, even flat panels with tracking. He calls it the Betaray. The idea is that a fixed transparent sphere can concentrate any available sunlight, direct or diffuse, and coming from any direction, to its center. At that point a small high-efficiency collector, presumably one that loves high temperatures, harvests the energy.

Broesser's orb is a lot prettier to look at than existing solar collectors, but for me two questions arise. For one, wouldn't a hemisphere work just as well and be cheaper to manufacture, easier to keep cool and more easily mounted? And if so, why not arrays of multiple, much smaller hemispheres as an efficient collector design for all those suburban rooftops?"

Hmm, maybe it was like in Kenya, where we "rented" books?

I spent 5 years (94-99) in Kenya, and every year, we would go to the moldy old book room to get books, which we would return at the year end (if you lost one, you had to replace at your own cost) I think they charged a fix rental, regardless of how many books, and they would regularly replace the books falling apart. I can't recall how much because we paid a lump sum every (four-month) term which included tuition, books and notebooks.

Which was good, because it was cheaper to rent books than to buy them out right, because with 35-36 textbooks for the 13 subjects we had, it would have prohibitively expensive.

If this is the same, then I guess maintaining digital copies is easier. You just issue a cheap tablet (a good chinese make cost for like ~$200 retail) and just copy the year's books on them.

I mean seriously, how far does this go?

I live in Pakistan, and I have a pressure cooker.

If I happen to be walking outside with my cooker, will I be carrying a WMD?

If a drone kills me, will I be counted as a terrorist?

Good luck carrying a utensil around. Frankly it's hilarious.

Hilarious, because cricket grounds are *much* bigger than baseball grounds ;p

Okay here is a deal: Explain me baseball, and I will explain you Cricket, because frankly baseball is totally whacky for me (not that cricket is any simpler, mind you...)

I *think* the idea is, pre-plan a route on your android device, then transfer/connect to the google glass, and wear that. Now you don't need to check your phone every time you face a corner, the route will be hovering over you all the time.

No more random wandering, checking map, wander some more...Leaves your hands free to drive, cycle, carry stuff etc. You could give it to pizza deliverers, bike messengers and post carriers, and pre-plan their route for the day, and even update it from base station.

( Whether this actually a good thing is a different question)

At least that's what I took from it. Anything else (take pictures, check calendar etc) can be done easier, better and possibly quicker from your cellphone (*most* of the time). Sure there will be time when PoV camera tricks would be beneficial, but I doubt the battery life would support that endeavor for long.

Funnily enough I recall a case of "vial infection", where a patient was administered a dose from a vial that had had minute fractures in it, causing its contents to be compromised, and the resulting injection severely disabled the patient (IIRC it was in the back bone, and he was left paralysed).

His lawsuit was dismissed, as I recall, because the administration could not have know about those minute fractures, and had otherwise taken all reasonable care to maintain those vials in proper condition.

Just a interesting anecdote I though i would share, sorry for the OT.

How many hardware guys does it take to change a light bulb? "Well the diagnostics say it's fine buddy, so it's a software problem."

Working...
