hello friends, do you know the proof for 0!=1?
here it is...

0! = 1?
n!/((n-n)!n!) = 1
(n-n)! = n!/n!
0! = 1
Another method
n! = (n+1) ! / (n+1)

7! = 8!/8
6! = 7!/7
0! = 1!/1 =1

2 power 0?

yeah friends, for many year anything to the power zero is one...
do you know the proof?.... now here it is for you....

20 = 1 …………………….?
     Log 20= log x
   0*log 2=log x
              0=log x
Antilog 0= x
           1=x or x=1

Another method:



Since the end of the 80's, Raphael from Plant Solar imagines and dreams to achieve a world tour while using a minimum of energy. He first imagines achieving it with the help of an amphibious microlight.
In 2003, with the partners of the company Horus Networks, they are the first in the world to propose to their clients a Web hosting and solar-energy powered electronic mails.
It is in 2004 that Raphael thinks about achieving the first tour of the world in a solar boat. At that time, it is not yet fashionable. He will thus have to first convince the future sponsors and the schools. To do this, he brings together and motivates a team of enthusiasts ready to follow him in this adventure.
Today, more than 100 persons are working, across the world, for the PlanetSolar project...


PlanetSolar is a multlihull vessel topped by a large array of photovoltaic solar panels, constructed by Knierim Yacht Club, in Kiel, Germany. Built in 14 months, the biggest solar boat ever built has impressive dimensions and is yet both silent and clean. The goal is to navigate around the world at an average speed of 7.5 knots - no mean feat for a solar-powered craft.
The multihull will be home to four sailors during the round-the-world attempt, and can accommodate up to forty people during the promotional trips planned at each port of call.
The ideal shape and size of the boat for the chosen route will be determined by in-depth research. The PlanetSolar engineers have to factor in a host of parameters - propulsion, solar panel design, energy storage, materials, and the external environment. A whole range of studies will need to be conducted in areas such as the boat's hydro and aerodynamics, the materials used, the management and storage of energy and, finally, the power plant and the optimal routing. A concentration of futuristic technology

planetsolar is a catamaran that runs solely on energy found in light. The additional removable parts allow it to expose a total of 537 sq.m of photovoltaic surface(solar panels) to the sun. This impressive data make it the biggest solar run ship in the world.
  • Length: 31 m
  • Width: 15 m
  • Length with flaps: 35 m
  • Width with flaps: 23 m
  • Height: 6.1 m
  • Weight: 95 t
  • Surface of solar modules: 537 sq.m
  • PV installed power: 93.5 kW(127.0HP)
  • Average engine consumption: 20 KW(26.8 HP)
  • Average speed: 7.5 Kt(14 km/h)
  • Maximum speed : 14 kt( 25 km/h)
  • Crew: 6 people
  • People that can go onboard: 40
  • Autonomy: Never-ending solar navigation.

Round the world in 160 days
In 2011, the first round-the-world trip powered by solar energy will be realized, with stopovers along the equator, where the maximum amount of sunlight is available. The over 50,000-km voyage will last 160 days, for an average speed of 7.5 knots. PlanetSolar's six-men crew will cross the Atlantic Ocean, the Panama Canal, the Pacific Ocean, the Indian Ocean and finally the Suez Canal, to return to the Mediterranean. After a roadshow with the village that will cross Switzerland in 2009, the boat will stop in cities like New-York, San Francisco, Singapour and Abu-Dhabi.

The stopovers (Miami, Cancun, San Francisco, Sydney, Singapour, Abu Dhabi) will be organised in large port cities; they will give the project a high profile, and will be used as a promotional platform for renewable energies, especially solar.
