1 million candlepower single LED

[L.E.D.]

Hmmmm....I wonder if this would EVER be possible?

 

[L.E.D.]

no seriously. A lightsaber wouldn't be one. How would they stop the photons at a certain point? and it would be a laser too. Or was it the lightsaber you wer refering to?

Well seriously, I been thinking of a flexible lasser, like the one that appeared on the movie Johnny Mnemonic (Kennau Reeves) the one used to chop up doors people etc. it has a cool factor of 10 in my scale anyway, maybe a fiber optic with a megawatt lasser attached to one end could do it, just dreamming

There is much info out there about light sabers and many replicas that are almost exact.

These, however, are not just the handle, but also a plasma tube attached that is fully functional. My friend has one, and it looks awesome!

I even saw one that the guy was able to excite the plasma molecules in such a way that it would look like it's extending when it was turned on, and retracting when shut off!

Unfortunately, I can't remember the websites I saw them at.

The sabers I saw ranged between about $300 and $2000.

I think a 1M CP LED is possible now if it is focused tightly enough

 

[lightlover]

1 million CP - that's amazing - even if it was focused absurdly tight.

machspass, please find the links for those *things*.

On a similar subject, there is a book called "The Physics of Star Trek" http://www.amazon.com/exec/obidos/ASIN/0060977108/qid=1013798884/sr=8 -1/ref=sr_8_71_1/002-5783277-6362458

What physics would we have to overcome to "do the stuff on Star Trek". It is a lighthearted, but serious non-fiction book.

The summary from amazon.com:
---------------------
Sure, we all know Star Trek is fiction, but warp drives and transporters and holodecks don't seem altogether implausible. Are any of these futuristic inventions fundamentally outlawed by physics as we understand it today? The Physics of Star Trek takes a lighthearted look at this subject, speculating on how the wonders of Star Trek technology might actually work--and, in some cases, revealing why the inventions are impossible or impractical even for an advanced civilization. (Example: "dematerializing" a person for transport would require about as much energy as is released by a 100-megaton hydrogen bomb). The Physics of Star Trek deserves merit for providing a refresher course on topics such as relativity and antimatter, but let's face it: the reason most people will want to read this book is simply that it's fun to poke holes in the premises of their favorite science fiction shows!

------------

It is written by by Lawrence M. Krauss, and Stephen Hawking.

It makes for interesting reading.

They discuss going to "light speed" (warp drive). I don't have the specifics, but they discuss that if "warp" were possible, it would take hundreds of years to accelerate to warp speed at a rate that a human body could withstand (the g-force). Star Trek overcomes this by the use of "inertal damnpers".

what about a 125 LUX LED?

 

[Chris M.]

what about a 125 LUX LED?

Measured at what point? Lux (and the imperial "Foot Candles" variant) are just point measurements depending on distance, angle, etc, from the lihgt source- and the closer you get, the higher the value.

Do you mean Lumens? That`d be good....hang on in there a few years and it`ll probably happen, believe me

 

[L.E.D.]

yes, I did mean Lumens, sorry.

did some one say lightsaber?

oh yeah i have one

here's my holding it with all my motorcycle gear on
