Currently, propeller pitch control uses three approaches: it is based upon either hydrolic oil pressure, mechanical control using lateral motion along the axis of the drive shaft, or electric motor control with the drive motor embedded in the hub. All three of these techniques are either expensive to manufacture and install, or expensive to maintain due to high wear rates or the close machine tolerances required.

BACKGROUND. Heretofore, soft body armor using Kevlar layering, or heavy armor employing hardened alloys and ceramics have provided substantial, yet marginal, protection for our troops and police against bullets and IED shrapnel.
Computational estimates involving meteorite impacts, thin-shell lamina, and the design of ablating re-entry vehicles, suggest a composite layering for helmets and body armor that can defeat penetrations by extraordinarily high velocity projectiles.
HOW THE ARMOR IS MADE. See Figure 1. Recent advances in

This device combines the action of a vehicle’s shock absorber and springs. Two of the major components of a suspension system are shock absorbers and springs. At first glance, they seem to have completely opposite effects; the spring bounces back, and the shock absorber keeps you from bouncing back. In actual fact, however, the difference is simply a matter of how energy is used. In the case of a spring, the energy from the movement

One of the major causes of cold in winter is simply that sunlight falls at a shallower angle than during summer, resulting in less heating per unit area than during summer. The other cause is, of course, cold air masses. While these are caused by the sunlight angle, they also explain why a bright sunny day can be freezing cold. This unit allows sunlight to be focused directly on any required point. Each unit consists

Current metropolitan passenger movement is generally concentrated in three areas: automobile, bus and rail, with user numbers descending in that order and potential energy efficiency ascending in the same order. The attraction of the automobile is mainly convenience for the owner, so alternatives must take this into account, but metropolitan stop and start travel is detrimental to mileage and causes increased emissions. Bus routes provide a partial alternative but they offer inflexible operation regarding routes

Problem: Severe storms (hurricanes & tornados) and their devastation.
Example: In August 2005 hurricane Katrina devastated the southern US coastal region and cost ~$110-billion in damages.
Solution: attenuate, redirect or terminate the storm by cooling down the warm airmass and by increasing barometric pressure.
Plan: Using transport aircraft for cooling hurricanes with dry ice. Using guided missiles for bursting tornados with explosives.
Experience: Those Storm Chasers have a lot of storm data and experiences flying

As the world witnessed the price of oil skyrocket to record highs in 2008, the need for alternate sources of energy have never been more self-evident. The proposed Lightning Power Generation System (LPGS) provides a means to directly capture the energy in lightning strikes, potentially providing an immense amount of pollution-free power to the commercial power grid. An average cloud-to-ground lightning bolt bringing negative charge to earth produces a peak current of 30 kiloamps (currents
