The electric solar wind sail, or electric sail for short, is a new,
revolutionary method for moving in deep space. The electric sail
promises to solve a long-standing problem how to move about in the
solar system without consuming much rocket fuel. The electric sail was
invented in Finland in 2006 as a byproduct of basic research of space
plasma physics, and is now being pursued by an international team
consisting of different groups mainly in Europe.
The electric sail consists of

Solar Cells in a solar panel are universally series connected resulting in a high output voltage for the panel,but introducing a serious restriction on suitable installation sites: There must be no shadows. Shading a single cell destroys the output of the entire panel. A second drawback of the connection: The cells must be protected, individually or in groups, by diodes that prevent cell destruction by excessive back voltage in case of unintended shadows.

FCHTMC is an engine that works from any heat source.
In the home and business applications Solar, Geothermal and CNG energy are all possibly available.
As the device is specifically designed to waste as little energy as possible, it is more efficient than current generation systems by more than 50%. The device utilizes lightweight materials that do not absorb heat energy within. These same materials are fully dense and nearly as hard as diamond. Through simple

Coverts any vehicle to electric power whether on solar energy or any fuel energy.
The device reduces the weight of the vehicle while also reducing the complexity of the vehicle power system.
The device quadruples to sextuples fuel efficiency through more efficient operation and reduced energy loss.
The device increases reliability through adverse conditions and allowing vehicles to travel in water up the top of the wheel-wells without any danger of stalling. If on solar energy the water

Hybrid electric vehicles are often expensive and still use fossil fuels. Eventually there will be no choice but to turn away from fossil fuels in any case. Pure electric vehicles may leave you stranded if you try to go beyond their range. Increasing the battery capacity, also increases the weight, and power requirements. Most trips are still with one person per vehicle and in general we exercise too little and infrequently if at all. Grid

White Paper Grail Pneumatic Two-Stroke Engine
This is a proposed clean emissions pneumatic two-stroke engine that does not have normal Two-Stroke cross contamination of oil and fuel (oil and fuel are not mixed).
Intake occurs when piston moves up by creating a vacuum under Piston Check Valve (6) (closed) and Piston (8) within the Engine Crankcase (16), (One-way) Intake Reed Valve & Throttle Plate (9) (IRVTP 9 opens) allow outside ambient air to enter Engine Crankcase (16). Simultaneously

A heliostat is a device that orients a mirror to reflect sunlight continuously onto a desired target. Heliostat technology has been used for commercial power plants of 10MW and more and occasionally on a residential scale for water heating applications.
Two years ago I had the idea to utilize the same technology to provide direct home heating and lighting by reflecting sunlight continuously into north facing windows. Such a heliostat might consist of a flat mirror

PROBLEM:
Many people choose not to use public transportation due to the fact it is many times uncomfortable, personal safety is a concern, and it is inefficient.
SOLUTION:
The Personal Transport Pod (PTP) provides a low-cost solution to the energy crisis and the concerns over global warming.
HOW THE DESIGN WORKS:
The PTP blocks off one lane on major highways in major cities to install a light, overground rail system. Rather than everyone sharing a large compartment
