' ..... Hence we can conclude that New Free Electron Wire is 1000/(2×10−6)=5×108 times more energy efficient than any metal wire of its kind. ..... '
[0075] Now, we will take the general example of a high speed 48 inch ceiling fan. We know on an average a domestic, high speed, 48″ ceiling fan consumes at about 75 watt of current.
[0076] We know that—
Watt (W)=volt (V)×ampere (A) (ix)
Thus the amount of current consumed by the fan will be—
Or A=W/V
Or A=75/230=0.33 A
Our aim is to make this sample ceiling fan highly energy efficient. Thus we will try to find out if we can drive the fan by supplying only less than 1 watt of electricity. ........ '

Super-insulated clothing could eliminate need for indoor heating
Quote from: hartiberlin on June 04, 2006, 12:21:56 PM
For those of you , who are looking to build your own heat pump
to reduce your heating costs you might have a look at this
ebay offer I just found:
http://cgi1.ebay.de/ws/eBayISAPI.dll?MakeTrack&item=6062510507 (http://partners.webmasterplan.com/click.asp?ref=284148&site=1382&subid=&type=text&tnb=32&diurl=http%3A%2F%2Fadfarm.mediaplex.com%2Fad%2Fck%2F707-3922-3266-17%3Fmpro%3Dhttp%253A%252F%252Fcgi.ebay.de%252Fws%252FeBayISAPI.dll%253FViewItem%2526item%253D6062510507)
Heat pumps are yet another craziness.
Effect will be -overloaded electric grid, blackouts and high price of electricity.
For every house that was heated by 10kW gas/wood or coal - with a heat pump they will consume 3-5kW electric energy more.
Another thing that is overlooked by "green Talibs" is DIVERSITY.
Once you eliminate gas,wood and coal from space heating mosaic and go for electric energy only, you will be dependent from one source. That is dangerous and expose population to threat of black outs, high energy prices due to energy monopoly .
Didn't you Germans learned a lesson from exposing yourselves to russian gas monopoly? :o
Cheers,

Pix,the E.U. energetic prgram has 3 steps,from nearly zero to net zero and final :
Zero energy ,means zero grid energy : no grid anymore !
In situ = local/consumer site ,energy generation !
How release camper ( caravans,RV and trailer owners) their energetic ( and water ) needs technically !?

p.s.: the russian/siberian gas ( but also shale-gas from/in Northamerica) gave the opportunity to hold the oil prices global down ( peakoil versus peakgas) !
Ucraine and Poland got Billions per year for gas pipeline distribution through their countries to western countries ,which now will become missed in their estatal budgets !
Each Billion western tributation x estatal credit lever 8 (reference : ERP-Funds) :
For each western paid Billion pipeline tax up to 8 Billions less estate budget PER YEAR ! It WAS lucrative !

;D You are kidding?
1. EU industry will collapse, due to overregulation, taxes and high energy/production/labour costs already biggest producers are moving away from EU. CO2 will be produced in wast amounts in countries who don't give a f*** about your eco-mania. India, China, Africa ect.
2. Every socialist utopia ends up in powerty, social unrests (see France example) and hunger. EU climatic and energy policy is such utopia that is already costing EU citizens extra money.
3. I wish you a very success , please put PV panels on your roof, put a tonne of storage batteries in your basement, install a heat pump and disconnect from the grid . Are you disconnected already? ;D ;D ;D

No,not due overregulation,but 3-/4-times credit activa leveraging( estate,comercial,private bugets +) ,now as final participant : the ECB ! Similar U.S.-society/F.E.D. !
Many producers in the E.U. losts /are actually loosing their temporary granted monopolist patent rights,they are now in challenge with world-wide low income/low regulation/low energy costs WTO-members !
CO2 is an industrial product,diverting C and O you get two chemical elements to work with !
2. Every socialist utopia ends up in powerty, social unrests (see France example) and hunger. EU climatic and energy policy is such utopia that is already costing EU citizens extra money.
The first ' socialist utopia' ? Sowjetucraine,constitued 1919 ,the U.S.S.R. later,1922 !

Actually I do not need it ,disconnection ! It is affordable enough ,the grid service ! ;) The E.U. program and outlook : final stage 2050 ! :)
Much tea-time !
Taking the 2022-2100 preview for Africa its population and the 20% migration quote( near,far emigration ) I expect 50% africanide population soon in 2050 : in Peninsula IBERICA !
E.U. : 1/3, Eurafrique Union ,E.A.U.,to differ from l'eau

As usual you contradict yourself.
First you say " grid no more needed". Then at second reply you admit you do not disconnect from the grid. ???
Please get in some kind of agreement with yourself.

I do not plan for yesterday and before,but today for the un-dated " tomorrow",2030-2040-2050- ...... !I have my priorities ! And financial aspects ! And idleness,based by cheap serving culture by others !
Not I ' say/write' about ' no grid anymore' ,it is actually E.U. program for the next DECADES ,not for today ! :D Give the people/peuple TIME and RELAXATION to change their thinking and habits !

Another sociologic 90' term : Factor 10 ; ten times faster,cheaper,lighter
90% less bureaucracy = 1000%+ efficiency
An example,here ,300 meters away :
A 3d house constructed in 24 hours on plot,the bureaucratic ' estatal' licence wait time for this house construction : up to 1,5 years !
500 days - 1 day = negavolution
Estate maior value versus Estate minor-value
Solar panels on the roof ?
Why not 'solar' better : artificial photo-/later phono-voltaic tubes in-door,under/on tect fixed,not ground place losts ?
Much battery capacity ? 1-1,5 KWh for modern private 3-4 capita households enough !

the foam-tect/-walls comercial energetic experiment results and we get in 0°C minimum climate zones and wished 18-20°C indoor climate ( eternal spring) an energetic heat need about 600 Wp per hour,this translates as heat pump C.O.P. 10 an electric Wp of 60 per hour !
600 Wp/66,5 sqm as improved actually 665 Wp PE/66,5 sqm Passive House energetic demand ! 10 Wp/sqm
Let us assume 100 eWp,the C.O.P. 10 is an average performance over the heating saison result,outdoor colder temperatures( and energy content in air) gives lower numbers !
E.U.- member Ireland only let now buildings being construct by Passive House,10 Wp PE/sqm, condition !PE = Primary Energy ;
In countries with older fossil derivate power plants and low/no RE production we can calculate with up to 2,6 KWh PE per KWh electricity consume,
a comercial ,not motor consume controlled inverter incorporated,air/air heat pump reaches a C.O.P. 2,5 all-time performance( Fraunhofer Institute comercial heat pump work performance comparison )
= C.O.P. heat pump / 1KWh electric EE in PE ~ Near C.O.P. 1
