Energy Harvesting in the home
« on: November 29, 2015, 02:52:13 PM »
 I am paying my monthly bills and that got me thinking.  I have a lot of energy sources I pay for every month.  Gas (heat the house, hot water, cooking), electricity (lights Electronics, room heaters etc), phone line,  water, sewage,  gasoline for car etc

So I was wondering if people had given a lot of thought about harvesting energy from various sources to supplement other sources.

Example Phone Line contains about 48v and you can use this with a regulator to charge a battery (cell phone, ipad etc) https://youtu.be/cUxx-4bUo4Q
Water pressure is high enough to run water to a tank in the roof, with a shutoff valve filled during peak hours, generating hydro electricity into the grid. https://www.youtube.com/watch?v=j9FodZfH3VQ
I am sure there are a dozen or so methods we could use to leverage the power in energy sources we are already paying for to supplement our energy consumption.

Anyone have some good ideas to leverage one energy source to offset another.

1.  The phone line is about 48 V as you say, BUT what good is that
     because you can only draw a few milliamps from it.

2.  It will cost you $$$ to get that water up on the roof.  So the net benefit
     from using that roof water to drive a generator, will be a net LOSS.

3.  Come on now, surely you must already know these things.  Lol
                                                                                                                                  .

Sadly yes :-),  but after paying my electric bill and gas bill today I was hoping for someone with a quick win.  OH For $50 you can build a  .... and save .... on your ... bill.

At first I thought this would only be a comercial alternative for products like Insuladd (ceramic microspheres),Radiance color (aluminium )
or similar insulating paints ,
but I never thought about the possibility to use such products for this :

http://www.patentauction.com/patent.php?nb=11044
http://www.osmatech.net/page3.html

Look for their several different experiments and their results !

The price for a can: http://www.ccmostwanted.com/store/Insulating-Paint-By-Osma-Tech-Uspt-Pending-62-230-865_201415112155.html

Painting a  globe and using this as e-candle heater ?
http://www.heatstick.com/_glowwarm.htm

                                                                :o
5.    We can paint rooms with combo 2 and with a heat lamp in the rooms it is possible to heat the whole room with just a 60 or 100 watt heat lamp.

                      room,from a doll house ?  ::) Or magical reality ?  8) sqm ?
                                     average room temperature ? in-/outside

 Yes,it is clear: each room in our world can be heated with just a 60  or 100 watt heat lamp !
                           During the cold winter and during the hot summer !

As forced heat source for thermo-electric converter ?

Interesting concept, Thanks Sorry where is this patented ? I can't seem to find the patent nor any test data.

I am not patent selling agent or product seller ,
my interest is to save energy and the related costs !

Here is my power costs for electricity. 
Winter
 Weekends / Holidays    Off-peak   $0.083 per kWh
 Weekdays:    7:00 a.m. to 11:00 a.m.    On-peak   $0.175 per kWh
 11:00 a.m. to 5:00 p.m.    Mid-peak   $0.128 per kWh
 5:00 p.m. to 7:00 p.m.    On-peak   $0.175 per kWh
 7:00 p.m. to 7:00 a.m.    Off-peak   $0.083 per kWh

Summer
Weekends    Off-peak   $0.080 per kWh
 Weekdays:    7:00 a.m. to 11:00 a.m.    Mid-peak   $0.122 per kWh 
 11:00 a.m. to 5:00 p.m.    On-peak   $0.161 per kWh    I used  365.07kWh
 5:00 p.m. to 7:00 p.m.    Mid-peak   $0.122 per kWh   I used  276kWh (this included weekends)
 7:00 p.m. to 7:00 a.m.    Off-peak   $0.080 per kWh I used 1,133 kWh


Total bill is about $285 every 60 days (there is delivery charge $80, taxes, debt retirement charge ?? included in that $285 as well. 

With battery's I could convert all on / mid peak to off peak 365+276=640/60=~11kWh per day so assume 1kWh per battery I need 11 car batteries and an inverter but lets make it 12 to handle peaks. 

I can get car batteries for about $50 each so 12 is $600 and a good inverter relays etc I think I could salvage around for an inverter 2000W say $300  and a transformer to charge the batteries say another $300 so all up about $1200. 

This is probably about 4 year ROI and then my batteries start to die, inverters burn out etc  but I would get a battery backup system if I lose power for about 8 - 10 hours (if it happens when batteries are charged and not end of on peak period when i am flat.

Anyone done something like this ?
