The main hurdle in the development of our world is the lack of affordable and environment-friendly energy sources. If billionaires and millionaires don't come forward now to share their dreams about the universal development of mankind, there will be no chance of human civilization going forward. If scientists came out with a solid solution to the energy crisis, half our problems would be solved. Thousands of super-rich people have lived on Earth, but unless they gave toward the betterment of mankind, no one remembers them.
