Answer: It’s generally more efficient to have a single, larger generator at the bottom of the mountain than a series of smaller cascading generators. Here’s why: However, there are some potential advantages to a cascading system in specific situations: In Conclusion: While there might be specific niche scenarios where a … Continue reading

How Much Land Needed to Install a Solar Plant with a Capacity of 11.1 GW?
Question: Assuming that virtually unlimited flat land is available in a desolate desert, how many square kilometers would be required to install a solar plant with a capacity of 11.1 GW? Answer: Here’s an estimate of the land area required for an 11.1 GW solar plant, along with some important … Continue reading
How Much Solar to Produce 611,800,000,000 kg of Hydrogen/Year?
Question: Given: a recent breakthrough of researchers at the University of Adelaide has yielded an electrolysis process that is 100% efficient with a catalyst that prevents the anode and cathode from decay; the amount of hydrogen desired is 611,800,000,000 kg per year; the temperature of the seawater is 60 degrees … Continue reading
Required Number of Rooftops Equipped With Solar Panels to Produce 611,800,000,000 kg of Hydrogen
The first step in this estimation is access the Global Solar Atlas; click on the specific location and look for ‘specific photovoltaic power output’, or PVOUT. This estimates the annual productivity of solar panels for a given location, measured in kilowatt-hours generated per kilowatt of peak capacity (kWh/kWp). For purposes … Continue reading
