International Electrotechnical Commission : World Plugs

International Electrotechnical Commission has a very handy (especially before travelling to a foreign country) list of different plugs (a total of 14 at the time of this writing), mapped to countries of the world.  So if you don’t have one of these:


make sure you check the list of adapters & converters worth buying before you fly out.  And while on the topic of this great variety, IEC also explains why there are so many and if this annoyance will ever be sold:

The IEC issued its International Standard for a universal plug in the 1970s; so far it has been adopted by Brazil and South Africa. It is unlikely that there will be a run on the standard in the near future. Literally hundreds of millions of plugs and sockets have been installed and who would convince a country to invest now in changing its whole infrastructure?

Most likely the future will lie with solutions such as the USB plug or possibly a multi-plug that can accommodate many different plugs, or even new technologies such as LVDC (low voltage direct current) or wireless charging mechanisms.

Current models of the engine weigh 500 pounds, easily fitting into the engine area of a conventionally-designed vehicle. According to CEO Charles Stevens, just one gram of the substance yields more energy than 7,396 gallons (28,000 L) of gasoline and 8 grams would power the typical car for a century.

The idea of using thorium is not new. In 2009, Loren Kulesus designed the Cadillac World Thorium Fuel Concept Car. LPS is developing the technology so it can be mass-produced.
