The result is planes are 300 times

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

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.

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.

led by business for profit.

If it's bigger than both of those, put it at the top of the list and bump the list down and so forth.

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.

This is called energy density.

Our fuel.

I needed tools that were robust, modular, highly efficient and optimized,

But no vehicles will need oil.

When the soft jaws are held tight for cutting, the master jaws should be at the middle of their travel

And this next shot here is one of the lunchrooms.

That's gotta be convenient.

Copyright is a property system.

That'll ensure the maximum number of casualties.

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.

They are looking at how ants and bees find their food and their flowers in the most effective way as a whole hive.

Fish farms pollute most of them do anyway and they're inefficient.

Those are the two hardest and costliest parts of making a car.

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

So if you take, say, natural gas, which is the most prevalent hydrocarbon source fuel, if you burn that in a modern

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

There's a way to practice intelligently.

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

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.

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

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

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

Also, we see how we measure the aerodynamic efficiency.

We've talked about the soil erosion.

And it turns out that a sound like this is the most energy efficient and practical way to transmit their call across the fields and savannahs.

I need fuel.

Primary fuel?

Fuel supply?

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

He's efficient, he's precise.

It's chemically fueled.

What do you know?

Rp7 rocket fuel burns at 5.000 degrees.

A superorganism can basically take what it wants.
