Nepenthes burbidgeae 50% silica gel, 20% "Sphagnum" moss, 20% fir bark, and 10% peat moss chunks. The highest growth rates were exhibited by specimens in 50% leached perlite, 30% long fiber "Sphagnum" moss, 10% peat moss chunks, and 10% fir bark, as well as media without fir bark and with a higher percentage of "Sphagnum". "Nepenthes burbidgeae" was found to tolerate temperatures in the range of 9 to 41 °C (48° to 105 °F). A nighttime drop in temperature below 18 °C (65 °F) was necessary for good growth; plants that were not exposed to such a drop grew around 50% slower
Home fuel cell reduces overall energy bills. Retail outlets like fast food chains, coffee bars, and health clubs gain operational savings from hot water heating. Since it is in general not possible for a fuel cell to produce at all times exactly the needed amount of both electricity and heat, home fuel cells are typically not standalone installations. Instead they may rely on the grid when the electricity production is above or below what is needed. Additionally, a home fuel cell may be combined with a traditional furnace that produces only heat. For example, the German company Viessmann produces a home fuel cell
