input: Gun laws in Texas

Texas has no laws regarding possession of any firearm regardless of age, without felony convictions; all existing restrictions in State law mirror Federal law. A person of any age, except certain Felons, can possess a firearm such as at a firing range. Texas and Federal law only regulate the ownership of all firearms to 18 years of age or older, and regulate the transfer of handguns to 21 years or older by FFL dealers. However, a private citizen may sell, gift, lease etc. a handgun to anyone over 18 who is not Felon. NFA weapons are also only subject to Federal restrictions; no State regulations exist. Municipal and county ordinances on possession and carry are generally overridden (preempted) due to the wording of the Texas Constitution, which gives the Texas Legislature (and it alone) the power to ''regulate the wearing of arms, with a view to prevent crime''. Penal Code Section 1.08 also prohibits local jurisdictions from enacting or enforcing any law that conflicts with State statute. Local ordinances restricting discharge of a firearm are generally allowed as State law has little or no specification thereof, but such restrictions do not preempt State law concerning justification of use of force and deadly force.

input: Alternative fuel vehicle

An alternative fuel vehicle is a vehicle that runs on a fuel other than traditional petroleum fuels (petrol or Diesel fuel); and also refers to any technology of powering an engine that does not involve solely petroleum (e.g. electric car, hybrid electric vehicles, solar powered). Because of a combination of factors, such as environmental concerns, high oil prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world.

input: Pressure-gradient force

The pressure-gradient force is the force which results when there is a difference in pressure across a surface. In general, a pressure is a force per unit area, across a surface. A difference in pressure across a surface then implies a difference in force, which can result in an acceleration according to Newton's second law of motion, if there is no additional force to balance it. The resulting force is always directed from the region of higher-pressure to the region of lower-pressure. When a fluid is in an equilibrium state (i.e. there are no net forces, and no acceleration), the system is referred to as being in hydrostatic equilibrium. In the case of atmospheres, the pressure gradient force is balanced by the gravitational force, maintaining hydrostatic equilibrium. In Earth's atmosphere, for example, air pressure decreases at altitudes above Earth's surface, thus providing a pressure gradient force which counteracts the force of gravity on the atmosphere.
with regard to the pressure gradient force air will always move from low to high pressure
