The LiFePo4 batteries have arrived

Ordered in mid-December, arrived on March 19. Low costs for electricity storage are a decisive factor for a real energy transition.

The doorbell rings, I rush to the door: "A package has arrived". This package turns out to be 5 large packages with just over 100 kg total weight.

These are difficult times, for the trip to the Hammerau I have to let me first in Hallein drill in the nose, the required COVID-19 test at the border.

On the left a box with a 120 Ah LiFePo4 battery, in the other 3 packages are 4 each 280 Ah LiFePo4 (Lithium Iron Phosphate) cells. 16 pieces of them will form a battery pack with 51,2 V. In the front is the BMS - Battery Management System for 16 cells. The minimum equipment from the house will be 3 battery packs of 14 kWh.

  Smash up stupid sayings and views


There are stupid sayings of supposedly serious professors like: “Without electricity storage the energy transition is technically impossible, with electricity storage the energy transition is economically impossible”.

These battery cells will be the sledgehammer to smash such stupid sayings and views.

GEMINI next Generation - energy + food + living comfort GEMINI next Generation - energy + food + living comfort
What can housing cost? Where can you build? How much Energy should a house produce? How much building material is needed? GEMINI n.G. is looking for completely new answers to these questions.


Prehistory of the GEMINI next Generation project
It started in autumn 1991 with the GEMINI habitable solar power plant, 2011 with the initiative Solar Building Land and 2018 with GEMINI 66 - we build our house ourselves.


Where can and should GEMINI next Generation be built? Where can and should GEMINI next Generation be built?
Using existing land better and building where conventional houses cannot or are not allowed is an important objective of the GEMINI next Generation project.


How much energy should a house generate? How much energy should a house generate?
As much as possible! Because we need to get out of oil, coal, biofuel, natural gas and uranium. Our houses should contribute as much as possible.

The heat pumps have arrived The heat pumps have arrived
On December 16, 2020 paid, on January 27 the ship arrived in the Slovenian port of Koper. On February 19, the 3 heat pumps could be picked up at a forwarding agency near Salzburg.


Rethinking cities Rethinking cities
The Green parliamentary group in the German Bundestag is hosting the online conference “Rethinking Cities” on March 19, 2021. We are participating in the virtual exhibition.


Rethinking the energy transition: The price lie Rethinking the energy transition: The price lie
The demand for “more money for climate protection” is based on the price lie. But we need more motivation, credit and opportunity for a real effective energy transition.


Summer / winter balancing of solar power - seasonal storage Summer / winter balancing of solar power - seasonal storage
Different approaches to summer/winter balancing compared. Seven different locations, from Oslo to Cairo, are examined for seasonal balancing.


Energy change - Food change - Social change Energy change - Food change - Social change
Everyone is only talking about the energy transition for climate protection, but we also need a change in food production and in the social sphere. A solution for all 3 changes.


Ventilation system with heat and moisture recovery Ventilation system with heat and moisture recovery
On May 13, the last of the ordered units is ready for pickup at a forwarding company. The trip was nearly for nothing, because the device only barely fit through the tailgate.


DIY test of thermal insulation of an alternative building material DIY test of thermal insulation of an alternative building material
Construction wood prices are rising dramatically spring 2021 and there are supply problems. But wood prices for other applications, such as this material, are falling slightly.


Would Germany be possible with 100% solar electricity? Would Germany be possible with 100% solar electricity?
The expansion of wind energy is faltering. Is wind energy really indispensable for the energy transition or would it even work with exclusively 100% solar power?


Ventilation systems with heat and moisture recovery Ventilation systems with heat and moisture recovery
Extremely economical and quiet, yet large power reserves to have the best indoor air quality even at a large party. Is of course part of the basic equipment.


More efficiency in heating, cooling and hot water by 3 new patents More efficiency in heating, cooling and hot water by 3 new patents
How can you achieve a higher COP with an air-source heat pump than with a ground-source heat pump, and how can you drastically reduce the amount of electricity needed to heat water?


Disruption at houses Disruption at houses
The market for homes is in as horrifying a state as the electric car market was in 2003: in the year Tesla was founded, the Peugeot 106 was a top electric car.

or how a house shrank to 2/3 of its size. Because of this visual misunderstanding, the video “Disruption in Houses” was published again with improved graphics.
