This is really starting to suck! Gotta fing buffer for 5 minutes to watch a 2 minute video? WTF!!!!

Nikolai Tesla surely thinks, even from the grave, that most of us are morons.

@2 100% agree. everyone, read about Nikola Tesla for the truth on this topic.

#2 #3 I agree if anyone has done any research they will know the truth .
Thomas Edison was known by those who worked for him more as a thief of ideas than as an inventor of anything that was in any way useful. The most unfortunate decision of Nikola Tesla’s life was to go to work for Thomas Edison. Edison was notoriously disdainful of those whose brilliance outshone his, and the Tesla alliance did not last long. Later Tesla worked on furthering X-ray technology, as well as inventing the Tesla coil, a device still used in many wireless products today. There is no denying that Nikola Tesla was a genius when it came to invention, but he definitely lacked something Edison actually did possess: the ability to lie your ass of, and manipulate public opinion and intimidate others. This was Edison in a box.

#5 Tesla also clearly underestimated the importance of patenting his ideas, which was the underlying success of Edison.

patents suck, knowledge should be owned by every one

Actually #4 is right. I think this guy is a little overrated.

#8 Shhhh... don't tell the sheep. Or you'll end up like #4.

#8, #9 - you know it's for kids, right?

#10 Even if it is for kids I don't like the note that he leaves the discussion on. For a high level science educator I am not happy that he ends his talk by basically saying we should just accept the status quo. There are still plenty of technologies that can increase the efficiency of cars and there are technologies that can increase the range of fuels we can use. One of the biggest wastes of energy in cars is braking. Current conventional cars take the kinetic energy of a moving car and do nothing but turn that energy into wasted heat in the brake pads. There are systems of flywheels and hydraulic pressure drums that can take that kinetic energy and store it and then release that energy as mechanical energy for acceleration. The system can even capture the energy of an idling engine. Another potential technology is a steam car. A steam car can use a greater variety of fuel types to heat water which then creates pressure in a tank. That pressure is then released to create the mechanical energy for acceleration. As a science educator I would like to see Mr. Kaku put some emphasis on the technologies we CAN implement in the near future.

#11: totally agree with you about the technology and power waste etc BUT it's called "big think" not "big discuss". So maybe thats's the whole point of that 2 minutes speech? To make kids think about solutions on their own? Just my loose thought.
And to be honest I don't like Professor Kaku tv shows or lectures - way too shallow for me now but if I was ten or eight that'd be just perfect. If someone wants to get more answers or knowledge there's TED for example. Or a science educator

Michio Kaku did not say gasoline is better, nor did he encourage its use. He just explained that gasoline is more efficient and why. He did explain the potential of another source of energy in the future.
