ADVISORY: With any technology, you take a high risk to invest significant time or money unless (1) independent testing has thoroughly corroborated the technology, (2) the group involved has intellectual rights to the technology, and (3) the group has the ability to make a success of the endeavor.

Uhh... Fuel additives will not void a new vehicle warranty UNLESS:

The additive causes physical damage, or
The additve adversely affects the emissions or the emissions system.
Acetone IS corrosive to many cheap plastics, but it does not harm most common metals such as steel or aluminum... If you dump a few gallons of acetone in the gas tank, then expect physical damage to the fuel injectors or other plastic parts in the fuel system. However, at the extremely low concentrations of acetone present (At one ounce per 10 gallons of fuel, that's 200 parts per million, or a 0.0025% concentration of acetone), the fuel system will not be harmed; ergo, any warranty will not be voided by the use of acetone in this manner. For the most part, if the plastics in your fuel system are designed to handle gasoline, then they will handle the tiny amount of acetone just fine.

GM's Hy-wire fuel cell vehicle is on display at the Greater Rochester International Auto Show today through Sunday at the Riverside Convention Center.

The Hy-wire prototype has been touring the world.

But it's the first time that the vehicle has been to Rochester, even though much of the research and development that went into building the car's skateboard-like chassis was done at GM's Fuel Cell Activities Center in Honeoye Falls.

Controlled thermonuclear fusion of hydrogen isotopes (deuterium and tritium) into helium offers the possibility of a virtually unlimited source of energy. There are primarily two experimentally different methods to cause controlled fusion of hydrogen to occur.

A magnetic field can be used to heat and confine hot hydrogen plasma for a time long enough for hydrogen atoms to fuse. Magnetic confinement "machines" such as the Tokamaks, Stellerators, and Magnetic Mirror devices fit into this category. Studies of the magnetic confinement fusion systems began in the 1940's. The current budget trend for magnetic confinement fusion research is downward and several significant programs have been terminated.

A second method of achieving controlled thermonuclear fusion uses laser or ion beams to deliver megajoules of energy in a few nanoseconds to the surface of a spherical mass of hydrogen. The hydrogen is driven radially inward at very high velocities. When the high velocity material stagnates, the temperature and density increase to extremely high values. The hydrogen can be compressed to a density of more than 20 g/cc and to temperatures of more than 100 million Kelvins. At these temperatures, the confinement time of a few nanoseconds owing to the inertial forces, is sufficient to allow the hydrogen atoms to collide often enough, and with sufficient energy, to fuse. Laser driven fusion was proposed by John Nuckolls shortly after the demonstration of a ruby laser by Ted Maiman at Hughes in the early 1960s. However, it was not until the early 1970s that well funded studies of laser driven Inertial Confinement Fusion (ICF) began. The ICF program is currently alive and well and several large projects at several laboratories are well funded. The major ICF projects in the United States are located at the Lawrence Livermore National Laboratory and Los Alamos National Laboratory (both operated by the University of California), Sandia National Laboratory Albuquerque, the Laser Laboratory for Energetics (operated by the University of Rochester, NY), and the US Naval Research Laboratory. The projects are funded by the US government through the Department of Energy

Apparently, the amount of energy used to produce a given amount of ethanol is actually greater than the amount of energy that is actually _in_ that amount of ethanol.
