Ski Lift can run on photovoltaic electricity of the summer
Batteries are getting cheaper and cheaper and will soon offer a cheap, short-term solution for storing energy for daily energy needs.
However, the long-term storage capacity of batteries, for example in an annual cycle, is not economically viable.
Although Pump Hydro Storage Technologies (PHS) is an economically viable choice for long-term energy storage with large capacities of more than 50 megawatts (MW) –
For locations where the energy storage requirements are often below 20 MW and have monthly or seasonal requirements, such as small islands and remote locations, this becomes expensive.
The research institute IIASA came up with a new investigation of the mechanical seasonal storage solution with sand and gravel in remote locations as part of larger off-grids or microgrids. The idea is as old as mining with cable cars.
With more fluctuating renewable energies going online, we will see more solutions like the Berg Gravitational Energy Storage. Perhaps we will see hundreds of ski lifts with a new summer purpose: store energy on peaks with gravel, sand or old concrete blocks and thus enable a completely solar-powered leisure activity even in the dark winter. On PV4.eu I have some weight to kwh calculator to calculate or to estimate lift costs.
Photovoltaic for Europe

Through a family business founded in 1985, I have been working independently with subsidiaries companies, for over 20 years in the field of computer science and renewable energies.
Even as a child, I was fascinated by the family's small hydropower plant in Styria and since then I have been in flames for sustainable solutions.

TOP 5 Most Efficient Commercial Available Solar Panels March of 2020
he photovoltaic industry has made tremendous progress and is the cheapest way to build new electricity production capacity worldwide. Another positive feature is that photovoltaics produce no emissions. Finally, the danger of fine dust as a possible intensifier of the course of a coronavirus disease has also caught the attention of the media. ? We should focus much more on resilient and decentralized solar energy, also to improve the health, living conditions and financial
Calculate Corona doubling by yourself
"The greatest weakness of humanity is its inability to understand the exponential function," said physicist Al Bartlett in his book "The Essential Exponential!" written. For Example there are 112 (known) corona cases in Austria today and the rate of duplication (outside of China) is 4 days. So could there be 1 million cases in Austria in just over a month? Do the calculations yourself with this doubling calculator: http://www.pv4.eu/calculate-corona-doubling-by-yourself_2048.html But you can use
Are rare earths used in Solar Panels and Batteries
According to a report by ADEME , the earths are not so rare. Especially in photovoltaic or solar energy and battery technologies are not widely used. Despite their name, they are not that rare. The rare earth consumption in the area of the generation of renewable energies is mainly due to the use of permanent magnets for offshore wind energy, which are only used by a small part of the wind
How many Exponential Steps to Mars
When we want to understand the exponential impact to the biosphere Johan Rockström can help, speaking from the World Economic Forum in Zurich: If I take 35 linear steps, I’ll barely reach the coffee stand outside of this room. What happens if I take 35 exponential steps(Steps doubles up)? I’d reach Copenhagen after 21 steps. Three more steps, I’m in New York. Another two steps and I encircle the entire
