How much further would we be technologically if we had embraced Nikola Tesla’s ideas and not Thomas Edison’s?

Nikola Tesla was the father of alternating current (AC), which is the most common form of electricity today. Thomas Edison favored direct current (DC), the type of electricity in batteries.

However at the beginning of the 20th century, Tesla invented and had perfected a method of transmitting electricty via the atmosphere, known as the Tesla coil. This method of distribution, would have allowed our homes, buildings, and vehicles to run without the use of fossil fuels or wires. Simply put, free energy for everyone.

Edison favored a land-line wire method of distribution and ultimately won, because there was money to be made. The people with the money obviously weren’t in the business to fund a completely free method of power distribution. Ultimately, we ended up with a monthly electric bill.

Where do you think humantiy would be today, if we had adopted this free, unteathered method of power distribution?

Can we use light to travel in space?

Light is a form is engery can it be used to travel in space iam not talkin abt solar power or anything like that.. i heard that light exerts a small force which we dont feel but can be deteched using advanced equipments and comlicated experiments… But the question stil remain can we use light to travel like we fuel in our vehicels.. What do u think about it..plz answer both questions

Religious devotion is a form of psychiatric disorder?

If I told my doctor I saw visions of the Virgin Mary, spoke with God and could ‘heal’ people with the power of my mind, I’d be commited to a psychiatric clinic and be given anti-depressant and psycho-tropic drugs , shock treatment, hypnosis, aversion therapy and be shunned by society.

Christians believe Jesus walked on water, brought Lazarus back from the dead, the Immaculate Conception. Crazy.

Do you believe they really did break the laws of thermodynamics?

There’s a small Irish high-tech company claiming they discovered a way of creating unlimited free energy. That goes against one of our most fundamental ways of understanding the universe: the principle of conservation of energy that says ‘energy can neither be created nor destroyed, it can only change form.’

If they are right it means we would never have to recharge our mobile phones or refuel our cars.

They challenged the scientific community to prove them wrong

The Challenge was published in The Economist magazine.

Here’s the link to the company:

Here’s the news from an accredited media source:

I am very sceptical about their claim, but if they are right this would be the most bombastic discovery in human history, it would change global economy forever.

What do you think?

What do you think?

why is it that most cellular reactions require energy in the form of ATP?

pls relate to the concept of gibbs free energy.
