# Quick Answer: Can Machines Be 100% Efficient?

## What happens if you bypass your electric meter?

Bypassing or meddling with an electricity meter involves moving, connecting and disconnecting live electrical wires.

And whilst domestic properties have “low voltage” it’s still enough to give you, your children, or pets a nasty electric shock, or cause an electrical fire..

## Did Tesla get free energy?

One of the Nikola Tesla’s attempt to provide everyone in the world with free energy was his World Power System, a method of broadcasting electrical energy without wires, through the ground that was never finished, but his dream of providing energy to all points on the globe is still alive today [1].

## How can you be 100% efficient?

Heat, sound, and mechanical energy are all unwanted byproducts. So if you put in 100 watts of power and get 50 watts of light the system is 100% efficient. There is a principle called “unity efficiency” that can allow you to produce MORE than 100% of the input.

## Is Carnot engine 100 efficient?

In order to achieve 100% efficiency (η=1), Q2 must be equal to 0 which means that all the heat form the source is converted to work. The temperature of sink means a negative temperature on the absolute scale at which the temperature is greater than unity.

## Is it possible to have a 100 efficient machine?

The short answer is: It can’t. Almost all machines require energy to offset the effects of gravity, friction, and air/wind resistance. Thus, no machine can continually operate at 100 percent efficiency.

## Which machine has highest efficiency?

The most efficient electrical machine is the transformer. Transformers have efficiency above 95%. The autotransformer has an efficiency of close to 98%. The maximum efficiency is achieved under the fully loaded condition.

## What is the least efficient animal?

“I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. And, humans came in with a rather unimpressive showing, about a third of the way down the list.

## What prevents machines from being 100 efficient?

Why are machines not 100% efficient? Machines are not 100% efficient because some of the work done by a machine is used to overcome friction. So work output is always less than work input.

## How can I get free energy?

How to make money from nothing (free energy)to build huge hydroelectric dams that produce electricity from the energy of falling water and running water.build solar farms that collect the Sun power.harvest the wind energy using wind turbines.use nuclear fission to generate electricity.More items…

## How can you make a machine more efficient?

Because all machines lose input work to friction, one way to improve the efficiency of a machine is by reducing friction. Oil is used to reduce friction between the moving parts of car engines. The use of oil makes engines more efficient. Another machine that loses input work is a bicycle.

## Why is a system not 100 efficient?

It is not possible to have an efficiency of greater than 1 or an efficiency percentage greater than 100%. This would mean that more energy is being transferred than is being supplied, which would mean that energy is being created. This would break the law of conservation of energy.

## What is the most efficient animal?

JellyfishAnd with the Jellyfish being the most efficient animal at moving due to its relaxed approach to movement, it seems that slow and steady wins the race!

## Can we start a machine without energy?

A perpetual motion machine is a hypothetical machine that can do work infinitely without an energy source. This kind of machine is impossible, as it would violate the first or second law of thermodynamics.

## What animal is always active?

Diurnal animals, including squirrels and songbirds, are active during the daytime. Crepuscular species, such as rabbits, skunks, tigers, and hyenas, are often erroneously referred to as nocturnal. Cathemeral species, such as fossas and lions, are active both in the day and at night.

## What is the hardest working animal?

The hardest working members of animal kingdomSalmon: Once a year adult salmon migrate back from the ocean to the river where they were born. … Ants: The workers and soldiers bring food, grow food, keep the nest clean and fight off enemies. … Honeybees: Finding flowers and then taking their nectar is very difficult because flower nectar is mostly water.More items…•

## What is the most energy efficient electric motor?

Tests carried out on a 44 megawatt 6-pole synchronous ABB motor shortly before delivery showed an efficiency 0.25 percent greater than the 98.8 percent stipulated in the contract, resulting in the world record for electric motor efficiency.
