But why is it inefficient? Also one little question: would I need to connect them in series or parallel?

A simple answer I got searching the web to as why we can't split atoms of non-radioactive elements is that they are stable.So,why can't we make stable elements unstable(radioactive)? Is this possible at least in theory?

If I were to make millions of contacts or "spots" on a long wire,and connect them in series(or parallel?),then make half of them warmer than the other half,would I get any useful voltage,i.e. electrical energy I could use to power something?

Yes you are right,we don't need any of that useless IR,but a little UV is good for some plants.I know there are lot of LED panels intended for plant growing,but I think they are not yet perfected,because some plants might grow well under them,but others don't.(also...the price...)Since I have...

Thanks guys for all your replies.I think I should've been more clear of what I need,I need an artificial light source that mimics the sun as closely as possible,I don't think any visible spectrum LEDs can do that.I mean,to get the same spectrum of light provided by fluorescent and HID lights...

Hello,I'm new to the physics forum.I have a question regarding fluorescence,and I didn't know where to post it exactly,so I decided to do it here... I like growing plants,and am forced to grow them under artificial lights during winter.I am always on the lookout for more efficient lights,that...
