Lost In The Fog

If you have an enclosed space like a tent and add 300w light/heat you probably have to use 300w of fan/cooling to get absolute room temp in that space again, like if the light never was on.

I'm pretty sure it doesn't work that way.

Think of a self contained regenerative cooling system which generates it's own electricity from the heat produced by the leds? ;)

Idk bout self contained regenerative. Maybe with a big chunk of heat storage through phase change material.

I do want to use some to power a couple canopy fans though. Sandwiched between the lights and a heat sink. I have not attempted to source said elements though. Too poor to mess with that yet haha

Lol stream lining it later would be a chore.

You know how big the first computer was in the days, now it fits on one of your fingernails.

How does it work then? :)

You got to try! These peltiers are getting really cheap now days. You can order a handfull from China just for a few bucks. Don't really know how the generating takes place in them and thresholds for it but I bet google can answer that.

On this topic, I've noticed the signs on the freeway are starting to use windmills to power the lights for the signs.... ingenious!
 
The temperature difference between hot and cold side creates a little bit of current. The idea would be in a water cooled system adding those would essentially give you "free" power for the canopy fans. It's not free your using power to run the mechanical water chiller. But adding the peltiers scavenges the needed energy for the fans.

Power recycling. :)

I've always wondered if solar panels under HPS lights could recycle enough juice to be useful. My guess is that the produced energy would be minimal in comparison to the cost to install solar.

I love the idea. Recycle that shizzz
:passitleft:
 
Love the ideas. It's doable but you would only be able to run a smaller fan maybe. Mount the panel on the side of the hps and take the reflector away, but that's lights taken from the plant in that way. The problem with these equations is that you never can harvest more than you put in. It's what every mad scientist dream of creating free energy. Replicate the sun in a small scale.

I have no background in mechanical engineering, but I do know that lights don't produce heat with 300 watts of electricity the way a heater would at the same wattage or they wouldn't be producing light! I also know that the wattage draw on the fan on the CPU of a computer doesn't need to be the same as the wattage draw of the CPU itself in order to remove the heat. I also know that moving hot air around doesn't require the same wattage as what it took to heat that air. There is no necessary equivalency between the wattage draw of the lights and the wattage needed to suck out the heat they create.
 
One other thought on water cooling vs fan cooling lights if I may. The only place I've seen at-home water cooling done is with computer towers, as heat in the metal case actually degrades the performance of the hottest parts (CPU's mostly, and hard drives). The cooler you make it, the better it runs. Lights don't run better when they're chilled so long as they're kept at a reasonable temperature (which is probably still pretty damn hot).
 
I get your thoughts shed. I'm not anyway looking to make the best cost effective way of cooling the lights. Is it possible, yes it sure is. Is it the best way of cooling lights, no by any means. Is it fun to do, it sure is. There are many ways to look at problems and many solutions. The situation that was unfolding this summer ment I couldn't grow my meds inside any more because of the heat generated by the lights. My fan was going full tilt on 80W, its a 160mm industrial fan. Sure I could buy another mobile AC but over here if u want something that's not a toy and over 1000w cooling you have to pay round 1000$ for this unit. That's alot of money. This is just another way of solving that problem.
