Agrivoltaics (Agri-PV, AV)—the joint use of land for the generation agricultural products and energy—has recently been rapidly gaining popularity, as it can significantly increase income per unit area. In a broad sense, AV systems include converters solar energy, also energy from any other local renewable source, including bioenergy. Current approaches to represent evolutionary development agroecology integrated PV power supply grid, result in nearly doubled could provide basis revolution...

Abstract. Global warming provokes permafrost thawing, which leads to landscape changes and infrastructure damage, problems that have intensified worldwide in all regions. This study numerically investigates the impact of different thermal stabilization methods prevent or delay thawing. To test technical methods, an alpine mountain site with nearby prone damage is investigated. Model simulations represent one-dimensional effect heat fluxes across complex system snow-ice-permafrost layers,...

Agrivoltaics (Agri-PV, AV) – the joint use of land for production agricultural products and energy has recently been rapidly gaining popularity, as it can significantly increase income per unit area. In a broad sense, AV systems include converters not only solar, but also from any other local renewable source, including bioenergy. Current approach to represents an evolutionary development agroecology integrated PV power supply grid. That results in nearly doubled While could...

We suggested earlier a new sustainable method for permafrost thermal stabilization that combines passive screening of solar radiation and precipitation with active solar-powered cooling the near-surface soil layer thus preventing heat penetration in depth. Feasibility this has been shown by calculations, but needed experimental proof. In article, we are presenting results temperature measurements obtained at implementation outside area which actually meant higher loads than area. have is...

The capacity of electric air conditioning and heating systems is growing rapidly, as the nameplate PV power plants. While demand for cooling has a positive correlation with solar irradiance, an opposite relation. In this study, different approaches to design (aggregation; thermal, battery, implicit storage) control (frequency conversion; variable adaptive load) their effects on efficiency off-grid active thermal stabilisation system based solar-powered heat pump are analysed. case considered...

Ice cellars are a traditional way of long-term storage meat and fish near the places their commercial production in Arctic during warm season. Due to degradation permafrost, these structures state disrepair everywhere. Using example Chukchi national village Lorino, where hunting sea animals is preserved, we have considered options for solving problem preserving caught meat. Economic assessments show that use permafrost facility reasonable storing more than 100 tons products; smaller volumes,...

The present way of building utility scale photovoltaic (PV) power plants is rather extensive: land use price often higher than for the relevant solar cell area, and lack faced in a well-developed area. Building an integrated PV more intensive way, although, area available optimum modules positioning limited. Another issue large construction wiring grid connection. recent trend getting output voltages over 1 kV. This reduces length (due to serial connection) cross-section lower current), as...

In this paper, we review practical limitations to laser space propulsion that have been discussed in the literature. These are as follows: (1) thermal coupling propelled payload, which might melt it; (2) a decrease mechanical with number of pulses, has observed some cases; and (3) destruction solar panels debris removal proposals create more rather than less. Previously, lack data prevented definite assessments. Now, new on multipulse vacuum impulse coefficient <mml:math...

In this work, we consider the concept of using a distributed solar power plant, setup on right-of-way railroad. The proposed solution allows to shave peaks electricity consumption without additional land alienation, existing grids. includes panels alienated PV can be placed directly cross ties damping elements, embankment slopes and land. This minimizing cost installation along railway tracks. North Caucasus was considered assess gross, technical economic potential solution. operational...

As a possible solution for the prevention of global warming induced thawing permafrost embankments, we have considered solar-powered heat-pump systems. This approach combines passive shielding solar radiation and precipitation with active cooling in summer; it is compared to currently used methods maintaining soil frozen. The main advantages such are power output positive feedback irradiation, no need fuel supplies, possibility combination existing thermosiphons. We shown using suggested...

Since stabilizes rock, its and will become a growing risk for mountainous countries like Switzerland, with potential implications rockfall magnitude frequency, mountain infrastructure, ecosystems, tourism. The long-term trend thickening of active layer thus subsidence table Swiss Alps is well observed documented. However, less known about how sub-seasonal seasonal variability atmospheric...

For instance, traditional passive techniques do provide rapid substantial soil stabilization. Meanwhile, active present financial constraints have yet achieved complete efficiency. Here we a novel...

It is hard to overestimate the role of winter roads in land logistics northern regions. In recent years, climate change has not only significantly reduced service life roads, but also made them less predictable. This forces transportation increase intensity, often at expense safety, or stop that suddenly, leaving vehicles and equipment unused for long periods disrupting project deadlines. Therefore, extending reducing dependence on local weather conditions a very urgent task. To solve it, we...

The projected increase in heatwave intensity and frequency will have far-reaching consequences for the human natural environment of Switzerland. Two particularly important are heat-related excess mortality low-lying areas acceleration climate-change-induced alpine permafrost thawing high-elevation areas. latter potentially impacts on hazards, ecosystems, infrastructure, tourism. In this interdisciplinary project, we assess potential using subseasonal predictions as a basis early warning...
