2. Solar-powered flashlight - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_flashlight

   A solar flashlight with built-in radio. Solar powered flashlights (American English) or solar powered torches (British English) are flashlights powered by solar energy stored in rechargeable batteries. Most of these flashlights use light-emitting diodes lamps [1] [2] since they have lower energy consumption compared to incandescent light bulbs. [3]

3. Solar-powered refrigerator - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_refrigerator

   The use of Kerosene as a fuel is now widely discouraged for three reasons: The recurrent cost of fuel, the difficulty of maintaining accurate temperature, and risk of causing fires. [4] In 2019, a solar powered portable refrigerator utilizing a brushless compressor, a lithium battery, and solar panels was introduced. [5]

4. Comparison of commercial battery types - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_commercial...

   Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.

5. Home energy storage - Wikipedia

   en.wikipedia.org/wiki/Home_Energy_Storage

   The stored energy commonly originates from on-site solar photovoltaic panels, generated during daylight hours, and the stored electricity consumed after sundown, when domestic energy demand peaks in homes unoccupied during the day. Small wind turbines are less common but still available for home use as a complement or alternative to solar panels.

6. Aluminium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Aluminium-ion_battery

   Rechargeable aluminium-based batteries offer the possibilities of low cost and low flammability, together with high capacity. [7] The inertness and ease of handling of aluminium in an ambient environment offer safety improvements compared with Li-ion batteries. Al-ion batteries can be smaller and may also have more charge-discharge cycles.

7. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   Electric fans used for ventilation may be powered by solar panels instead of mains current. This is an attractive option because once the capital costs of the solar panel have been covered, the resulting electricity is free. If ventilation needs are greatest during sunny weather, a solar-powered fan can be suitable.
