After a Long time

Finally, I think this site's gonna get a well deserved makeover. I've not been able to update this blog for long.
Now, after exams, change is in the air.

Hey you have some great ideas,hope you keep it up



Experimentally I have developed a system of warming of water very special, based on the radiation of the black body. Since you they will know the typical systems they paint negro the panels (which are of copper), because of it the costs are very high. The black color is essential.
Well, simply one day I thought why not paint negro’s water? This way the water will absorb directly the solar radiation and us we avoid the copper.
How I can use the heat was absorb with this black water?. Simple, with a heat interchanger water - water . Then I set to work in this experimental project and it leads it to end.
The scheme consists of a panel of aislapol identical of black face painted, on it 30 meters of transparent hose, glasses to cover the frontal face of the panel, a small pump to re-circulate the black water, a coil of recooked copper and two pots one for the circuit of black water and other one to store the clean water.
The pump makes circulate the black water along the panel, then absorve heat and it transmits it to the clean water, this on having passed for the coil of copper that one places inside the container of clean water. In the experimental installation I uses a photovoltaic panel of 35 watts to give energy to the pump. The pump belongs to 12 volts, consumes 2 Amperes and delivers a flow of 4 liters per minute. In conclusion all the energy used to warm the water was “A” “Solar power”, so much thermal as electrical.
The results are:
With this super-economic panel it is possible to to warm to 60ÂșC a daily volume of 70 liters of water. Only I use 30 meters of transparent hose (6.000 $ Chilean CLP), if you want to warm up more waters, simply it is necessary to to add more hose tranparente, the pump serves to be used even with 120 meters of length, for which there are no more modifications.
The reservoir of clean water you can place it where it accommodates you, not necessarily in the roof as the typical ones.
The occupied space was about 1 m2, the weight of the panel about three kg. Therefore, if you want , you can cover the complete roof with these panels, it will not affect the structures of roof house.
If they want to implement it in his houses they can contact me, if they have doubts, I will answer them tast.

Hi, I have seen a sun tracking system that used refrigerant in pipes around the collector to adjust the direction, it was on this TV program about buildings that used big fiber optics to transfer light from the roof to the rooms inside. I wonder do you know anything about it? I'd like to find out More details. kzin(at)paradise(dot)net(dot)nz

Hi, i am, thanks very much for youe comments.
Now , is you can make one solar tracking system , i prefer use small Photovoltaic cell with voltage max. on 5 volts , low current, The small cell is as sensor, you can conect that to electronic control with analogs inputs 1-5 volts. You will need install aprox. 12 cells , each one on diferent position to sun, next step you can make register on controlles, after that you can make logic program on controller ,.
Controller will send the output to one servomotor. The servomotor move and ajust the direction to tacking the sun.
In case do you need contat me , send me email to

I would like to hear more about how you plan to create your renewable energy in your rented room. Going green is great and we all need to add a vertical wind turbine or solar panels for homes to generate our power.

Good work Mridul. I am working on feasibilities of small capacity generation through Reneable Energy in India. I am sure your blog would be useful for giving benefits of Renewable energy to low income and remotely located population in India
