Yea those bars are much larger for cooling block. It definitely would make for a much better setup using those. I mean the gpu cooling blocks arent expensive, but have limited space. I will do one that way though for the other large tank.

Its the same in the usa, regulators are trying to get rid of net metering like it somehow hurts them when in actuality, it makes the grid MUCH more reliable and stable. The more people feeding in with solar, the less their grid costs to operate as it evens out the power load because your loads...

I think im just cautious with 2-3 just so they run minimal power to each raising their efficiency and also as a just in case as Michigan winters can be unpredictable. Most well insulated and air tight designed homes can take less than 20,000btus to be heated with no outside heat sources like...

You mean 1000w of solar panels right? Btw, if you are getting solar panels, get them from sun electronics. They are the cheapest for solar panels you can get. Usually way less than $0.30/watt. Will the system be just dc to feed the leds with a battery buffer or will you use a grid tie inverter...

It really is quite sad. If everyone knew all the tech that is out there and the insanely fast returns on investment just by using them, we would be living in quite a different world right now. I know some people are super stubborn in their ways, that might be a big reason. I know a lot of...

I actually have an electric car and all power tools and lawn equipment is electric as well. As a matter of a fact my quads are electric, electric dirtbike, electric bicycle, working on converting a go kart to electric, and converting my boat to electric probably next year. Plan is to have a well...

Not only that but combine with slate floors and walls where the light touches and the rock can save heat from during the day and release it at night. Lots of cool design features like that can really cut costs across the board.

Thats about right. Lots of renewable resources to go after. Im in a really crappy area for solar however... Tons of trees that i cannot get rid of Because the property is only 1/5of an acre and trees practically surround it. My next home will have more land and a solid southern facing roof for...

Its more experiment to see how much it does, im not expecting those numbers, just would be cool if it did.

Yea. It basically slows the transfer of heat which may ruin cobs...better test with the $2 chinese ones lol

The idea is that heating the one side of the plate directly with the cobs mounted to it and mounting the other side of the plate directly to the water block. As the heat flows through the plate, it creates a current recovering somewhere between 10%-30% of the heat that goes through it converting...

Has anyone ever dealt with peltier plates? Im wondering if the difference in heat between the water block and the cobs could create power to be fed back through? I know they are only at most 30% efficient, but if i can take 30% of 150watts of waste heat, then the overall efficiency jumps up...

Ok, so original plan was one citi 1212 4000k gen 5 cob on a heatsink, then they wanted an entire small room they built to be lit up with one single light, so i quickly put together a system of 4 citi 1212 5000k cobs that i had on hand using a long bar water block and a radiator in the barrel to...

Well not too much going on under there, just drain from bell syphon, then the pump is down in the bottom pumping up to the grow bed. Im relying on pics from the in-laws so its an accomplishment actually getting anything to show lol. I still gotta get their final led system set up. Its pretty low...

I dont understand why cree has become stagnant on their products.they used to be at the forefront of leds and had record after record for efficiency. Now companies like citizen keep improving to the point where there isnt any reason to buy cree cobs other than for their binning of high end cobs...
