Galileo said that the Sun revolved around the Earth, and that the Earth was the center of the universe ! (:
Answer:
Explanation:
There are many avenues of "current" research, so to spark.
- Improved efficiency and lower-cost photovoltaic cells,
- Improved, and lower cost, battery technology,
- Systems for harnessing tidal and wave power from the oceans,
- Molten salt energy storage for solar reflector arrays,
- Hydrogen-powered motors for vehicles,
- Gas storage (hydrogen) for transportation.
- Energy storage systems such as flywheels, molten salts, hydro power, etc., and
- Higher efficiency motors and electromagnetic devices
- Replacement of fuel-powered motors with electrical motors in transportation, including vehicles, ships, and planes.
Finding less expensive, and non-toxic materials is important. Less-enpense, and safer, alternatives to rare earth metals is sought.
Jets streams play a key role in determining the weather because they usually separate colder air and warmer air.
