Solar panel
* absorb energy from the sun.
* are a major use of germanium
  - also lightweight, so it is easy to lift into orbit
  - at their maximum effectiveness during peak sunlight hours
  - devices that convert light into electricity
  - different to solar cells
  - located in roofs
  - now a common sight in the rural settings worldwide
  - one of the most popular sources of alternative energy for home power systems
  - simply a recharging system for battery powered energizers
  - still expensive to manufacture
* attract, store, and convert sunlight into electricity.
* can power solar motor , and LED
  - produce power during hot peak energy days in the summer when the winds are low
* charge truck batteries that drive the paddlewheels in the basins
  - up the battery in about six hours
* collect the energy needed to recharge the radios' batteries.
* convert light energy into electrical energy
  - radiant energy into electricity
* convert sunlight directly into electricity
* generate electricity to operate computers, printers and microscopes.
* generates electrical power that gets stored in the rechargeable batteries.
* give power to people.
* have no moving parts, require little or no maintenance and last for decades.
* help provide energy.
* keep the batteries charged.
* make renewable energy.
* produce enough energy for minimal needs.
* provide electricity for hot water and lights.
* provide power for lights and fans only - no electric plugs available
  - only, no electric plugs are available
  - gas lamps are provided for emergencies
  - medical and communication equipment
  - some electricity
* recharges batteries with indoor light.
* require continuous sunshine, unless the energy can be stored in batteries.
* transform light energy into electrical energy
* work by gathering solar rays from the sun.
  * ' get energy from the sun to create electricity. Solar panels make renewable energy. A common misconception about solar panels is that they produce energy from the sun's heat. They actually produce energy from the sun's light. Unlike a generator, a solar panel solid state way of producing electricity, meaning that it has no moving parts. Solar panels are often mounted on rooftops. Commercial or industrial installations are often on trackers mounted on the ground.

Spark plug
* Some spark plugs require a higher or lower voltage than others.
* are automotive products.
* are electrical components
  - one of the most misunderstood components of an engine
  - part of ignition
* give up heat slowly.
* help to remove the heat generated in the combustion chamber.
* is an electrical device
* thread into the center of the combustion chamber through wells cast into the head.

Surge protector
* Most surge protectors work by diverting an increase in voltage from hot to neutral or ground.
* are for surges in power.
* come in varying shapes and sizes.
* prevent electronics from being damaged by power surges produced by storms.

Surge suppressor
* Some surge suppressors fail in thermal runaway, can overheat and cause fires.
* act as a fast switch to divert electrical transients and equalize potential.
* are a second stage of an interior defense system
* can help with protection, but nothing beats physical disconnection.
* come in all sizes and types.
* protect against catastrophic transient events like lightning strikes.
