Volt Harvest

Volt Harvest is an offline guide to renewable energy technologies for anyone who wants to understand how modern sources of power work. Explore 48 technologies, compare different approaches to energy generation, and build your knowledge through concise reference cards and a True or False challenge.

The catalog covers solar collectors, wind turbines, hydropower systems, geothermal stations, biomass boilers, hydrogen cells, and other renewable energy technologies. Each entry includes a visual marker, source type, installation scale, and a region where the technology is commonly used.

Open any technology to explore its information in three different formats. Read a continuous explanation, switch to a compact list for quick reference, or use the parameter table to see important characteristics in a structured form. Entries also include variations of the technology and a suggested companion that can form a useful energy combination.

Search the collection by name or use three rows of filters to narrow the catalog according to its available characteristics. Switch between grid and list layouts depending on how much information you want to see while browsing.

Save interesting technologies to your favorites for quick access later. Every technology you open is automatically added to your read collection, making it easy to distinguish familiar entries from those you have not explored yet.

The home screen brings your progress together in one place. See how much of each energy-source category you have covered, review represented regions, discover unread technologies, and open the featured Source of the Day. A Term of the Day provides another quick way to expand your renewable-energy vocabulary.

A separate activity tests your knowledge of installation peak power. Each round presents a statement and asks you to decide whether it is True or False. Choose between a 12- or 15-statement session before starting.

After completing the activity, the results screen shows your total score and a full review of every round. Compare your answer with the correct one and revisit the concepts that need another look.

Volt Harvest works completely offline. No registration, account, cloud synchronization, or internet connection is required. Your favorites, read entries, and latest challenge result remain stored locally on your device.
