  • The electrostatic field lines around a point charge and a cylinder.   The electric fields are shown by placing the two charged objects in a pan filled with cooking oil and pepper flakes.  The pepper flakes align in the electric field and allow visualization of the field.  In this image the left point is charged to -30,000 volts while the right ring has a potential of + 30,000 volts.  This image is part of a series showing different charging conditions.  Of special importance is the lack of fields showing inside the cylinder.  This is the classic case of no electrical fields inside an electrical conductor.  In this image the cylinder acts as a Faraday cage and shields the enclosed area from any external electrical fields..

  • The electrostatic field lines around  a point charge and a plate.The electric field is shown by placing the two plates below a pan filled with cooking oil and pepper flakes.  The pepper flakes align in the electric field and allow visualization of the field.  In this image the left point is charged to -30,000 volts while the right plate has a potential of + 30,000 volts.   This image is part of a series showing different charging conditions.

  • X-Ray of the  Chinese lantern plant, (Physalis alkekengi) also called the winter cherry or bladder cherry is a member of the potato family.  The chinese lantern plant is used mostly for decorative purposes, but is also harvested for its fruit. The fruit has twice the Vitamin C of lemons and resembles a blonde-red cherry tomato.

  • The electrostatic field lines around two parallel plates are shown by placing the two plates below a pan filled with cooking oil and pepper flakes.  The pepper flakes align in the electric field and allow visualization of the field.  In this image the left and right plates have idential gharge of +30,000 volts. This image is part of a series showing different charging conditions.

  • A velomobile or bicycle car is a human-powered vehicle, enclosed for protection from weather and collisions.  Here a young man is peddling the velomobile in a recumbent position.  The velomobile is built on a recumbent bike frame with two steerable wheels in the front and one wheel in the back.  This tricycle design allows for a stable vehicle on wet roads.  The vehicle is air streamed to decrease wind resistance and shield the rider from rain.  As fuel consumption becomes more of an issue, more commuters will switch to human powered vehicles.
