^ I have no idea what that means

It helps settle upset stomach, which I have due to eating too much KFC

Well, before all that..:laugh3:.. I was thinking about (without too much detail here) why is it that the theoretical maximum efficiency for a sterling-cycle engine / concentrator mirror apparatus has a higher efficiency than a solid-state semiconductor solar cell?? Sterling&solar could achieve mid 30% max efficiency theoretical, and silicon solar cells could achieve 25% max. Well, that sounds backwards! There must be some way to up the efficiency of a PV cell using newer tech. :confused:

Dude no way! I was just thinking the same exact thing!:stunned:

 

Except I think silicon solar cells could potentially reach 30% max, but Im a little too optimistic sometimes.:laugh3:

Yay! I just bought O.A.R.'s new album "All Sides" and it's freakin AWESOME!:D:D:D

^ I know right? lol

Are you talking about the album?

Cool! Isn't it amazing? What's your favorite song on it?

I really like Shattered

Same here. Also This Town. I also love Living in the End and Something Coming Over from the MSG performance.

damn it!

i need to save some money for next year

I HAVE TO SEE Coldplay live this time!

I'll have to find a job

Wow! Well, now that's a Vulcan thing!:stunned:... Yes, it's a problem with the basic design; some electrons get re-captured, others are lost in crystal defects; so the best with regular NP junctions is around 25% according to the books. Still, these PV cells work in the red light area of the spectrum. You can do some things to create cells that respond to the other colors, but then it's layering, etc. Might hit 30%. I had thought about a light antenna array, if you could get a filter or something to make sunlight coherent (but that drops efficiency too!).. Well, someone tried artificial photosynthesis (making hydrogen instead), but that's maybe 1-3% (pathetic at the present!):laugh3:.. So, maybe some way of putting the semiconductor atoms atop carbon nanotubes, to capture more electrons from the semiconductor-dopant element?? Or, maybe caging the semiconductor in a carbon nanotube in such a way so that the electron is more apt to escape into the conductive tube?? Hmm..

I'm going to panic until I see these tix at my door!!! (I've literally never had to pay for Coldplay tix before, so I'm going to be nervous til I have 'em in my hot, shaking, sweaty little hand,lol.)

I'm so tired...

I should catch up on some sleep but I'm afraid I will only think of them... :undecided:

This is a great song!

I'm hungry and bored.
