The biggest problem of photovoltaic is to bring offer and demand together. Study about possible solutions.
|
| Biomass wood
| | |
The wood ofen will become a luxury, instead of 4,3 kWh heat by burning, we will invest 10 kWh electric power to produce 1,65 methanol from 1 kg wood.
|
| Photovoltaic 30% yearly increase
| | |
Against the prognosis of the Energy Watch Groip, reduction of the crude oil production to 39 million barrels a day in 2030, is a 30% increase of the photovoltaic world market not enough.
|
| War economy: extreme increase of photovoltaic world production
| | |
From 2010 to 2014 radical increase of the photovoltaic world production with 200% per year until 1000 GW yearly production is reached, further extension with 10% per year.
|
| Biomass in the change of time
| | |
Biomass is in the present seen as a supplier for energy, but this will change in the future to a supplier of raw material requiring energy for processing.

Fair report from the building and living February 14 to 17 2007 in Salzburg.
|
| 2008 News about energy, building and live
| | |
A time of fast change. Nothing remains in the energy sector like it was. Project designers have to learn to think with a complete new cost structure.
|
| Heat pump: the enemies of the heat pump calculate wrong
| | |
The enemies of the heat pump calculate wrong. The electric power consumption of the oil heating system is ignored, the development of the electric power production is wrong foreseen.
|
| IEA: Forward, we have to go back
| | |
Dramatic change in the prognosis: WEO 2006 more and more oil production, Energy Watch Group 2007: decrease of oil production. Will the WEO 2008 be worse than EWG 2007?
|
| Photovoltaic vs nuclear fusion
| | |
We write the year 2040. The resarch ober nuclear fusion has made the necessary progress for a commercial operation, but what is with the economy?
|
| The responsibility of the IEA
| | |
Most politicans have trusted the prognosises of the IEA very much. For this trust, they are ne reprehended by the IEA, because they did not enough for energy efficiency.
|
| IEA oil prognosis
| | |
The IEA wants to change from a demand oriented prognosis to a prognosis based on the production possibilities of crude oil and natural gas.
|
| Rationality 1992
| | |
What would be, if starting with 1992, the year I invented the GEMINI house, the photovoltaic world production would have been increased by 60% per year?
|
| Solar duty instead of universal conscription
| | |
Since thousands of years is the draft an extreme life-threatening concern. What would be compared to this a solar duty for roofs.
|
| Replace crude oil by photovoltaic
| | |
From all methods to produce energy is only with photovoltaic the magnitude reachable necessary to solve the problems of humanity.
|
| Dessert and dry areas
| | |
A sea water desalination system supplied by solar electric power near the shore needs for the photovoltaic only 0.8% of the surface to irrigate with 500mm water a year.
|
| Scenarios of energy development
| | |
Description for the 4 different szenarios of photovoltaik world market development.
Explanation for the increasing amount of electric power to replace 1 litre of crude oil.
|
| Replace crude oil by electric power
| | |
The amount of electric power to replace an unit of fossile energy can, depending on application, be complete different.
|
| Electric power saving competition
| | |
The ''Bund der Energieverbraucher'' (energy user association) in Germany starts a competition to save electric power. Each saved kWh is rewarded by 2.-EUR
|
| Ilisu dam
| | |
The plan is to produce 3833 GWh electric power per year by a 313 km² large artificial lake. 78,000 humans have to be resettled.

On the caravan show is outside an overview about the numerouse offers of mobile homes. From cheap mobil homes up to low energy house standard.
|
| Photovoltaic or solar collector
|
| 
| | |
Best of all 100% of the roof surface with photovoltaik and 100% with Sonenkollektoren. This goes by a new technology which unites both functions in the same surface perfectly.
|
| Franz Alt! 18 degrees.No! Thanks!
| | |
Franz Alt propagates 18 instead of 24 degrees of ambient temperature, however, there is nothing more superfluous than to freeze at 18 degrees in a solar house with an electric power and warmth combination system.
|
| Smart House terrace

| | |
About 200 m² ground in a settlement of such compact homes in a beautiful landscape, efordable living in the green, so that there is enough money left.
|
| Roof areas for the generation of energy
| | |
It does not matter to south, west, east or even a little bit towards north. Each roof surface, each partway sunny facade is urgent necessary for the generation of energy.
|
| Electric power and heat of wood
|
| 
| | |
The oil price is rising, Peak oil dreaded by the economy gets closer. Which role can play wood in the future of our mobility and energy supply?
