This stove burns oil.

This stove uses kerosene.

The result is planes are 300 times

So the conclusion is planes and cars are roughly equally fuel efficient.

Normally, efficiency is crucial because the fuel cost of your engine over its life dwarfs the cost of the engine.

General Electric natural gas turbine, you'll get about 60 percent efficiency.

The only way that they're going to let themselves out of energy poverty is by adopting fuels that are more efficient, that are less expensive, that are better for human health, that are better for the environment, and that are more productive.

What happens is you have crossing over, and it's a surprisingly organized process.

Here. The Pirate Bay. And that's all.

Be fast.

Let's see how far we can go by bending rules as we estimate the fuel efficiency, the miles per gallon of a 747.

Anybody who's trying to sell you biofuels, or this kind of thing, what do you do about the thermodynamic inefficiency of combustion engines?

The coal in the stove is burning.

We only burn up a small amount of the uranium that's in there, we take it out and we stick it in a spent fuel pool.

It's not about the things that it brings.

There's a way to practice intelligently.

But the heaps that we were talking about the overhead is pretty raw and we get this kind of running time, the elapse should be pretty efficient.

And this next shot here is one of the lunchrooms.

That's gotta be convenient.

Maybe a decade, according to my friends in Detroit.

So the total running time ends up being we do (nlogk) operations.

So I'm going to talk about some projects that have explored these ideas.

A superorganism can basically take what it wants.

We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency.

Jet fuel.

In the middle eastern states which have access to forests and to agricultural waste, they might say, we're going to lead the nation in biofuels.

We also discovered that efficiency doesn't matter so much if your energy source is free.

let's compare that with a number I've just mentioned.

I made a promise that the next time I would fly around the world, it would be with no fuel, independent from fossil energies, in order to be safe, not to be threatened by the fuel gauge.

I need fuel.

Primary fuel?

Fuel supply?

Our fuel.

Also, we see how we measure the aerodynamic efficiency.

He's efficient, he's precise.

Another application is in local search.

you can see now the whole thing takes up far less space.

Mine fuel

Primary fuel 2893 KRG.

What is he saying about the fuel?

Fuel cells.

All that driving that we've been doing out in the suburbs, we have doubled the amount of miles we drive.

Fuel, Skripach, fuel...

Fuelinjected.

And if you do the energy budget, the data transmission comes for free highly energy efficient.
