I think greenhouses require an infra red absorber inside in order to work.Baluncore said:Maybe a sheet of clear polythene over the top, to get some local greenhouse effect.
While I think, your 'IR absorber', (a wavelength converter to IR), would be the soil that was first sprinkled onto the surface. The clear film reduces the loss of half the IR, before the IR can melt the snow.tech99 said:I think greenhouses require an infra red absorber inside in order to work.
Sprinkling soil on the ice wall around your driveway can help increase traction and promote melting. The dark color of the soil absorbs more sunlight, which can accelerate the melting process of the ice. Additionally, the soil provides a gritty surface that can help prevent slips and falls.
Soil is not necessarily more effective than salt for melting ice. Salt lowers the freezing point of water, which directly causes ice to melt. However, soil can be a good alternative or supplement, especially if you're concerned about the environmental impact of salt or if you need additional traction on the ice.
Coarse, gritty soil or sand is most effective for sprinkling on ice walls. Fine soil or loam may not provide as much traction and can be less effective at absorbing sunlight. Sand, in particular, is often recommended because of its abrasive properties.
Using soil or sand on ice walls is generally considered environmentally friendly compared to salt, which can harm plants, soil, and water sources. However, excessive use of soil can lead to sediment runoff and may require cleanup once the ice melts. It's important to use an appropriate amount to balance safety and environmental impact.
The frequency of application depends on the weather conditions and the amount of ice buildup. Generally, you should sprinkle soil whenever you notice that the ice is becoming slippery or if the existing soil layer has been covered by new ice or snow. Regular application during icy conditions can help maintain safety and promote quicker melting.
