It's not good stuff, and it's from inefficient combustion, not from combustion itself.

Oxygen is needed for combustion.

We have more sharks, more biomass of snappers, more biomass of herbivores, too,

larger biomass inside the reserves.

Now what we see is huge biomass towards the poles and not much biomass in between.

The internal combustion engine is not sustainable.

Spontaneous human combustion is rare and scientifically unexplainable.

Any common denominators in cases of spontaneous combustion?

This is what we call the biomass pyramid.

But you can imagine the biomass that represents.

So this is our internal combustion engine for creativity.

And the biomass this is the most spectacular change 4.5 times greater biomass on average, just after five to seven years.

What about the internal combustion engine, which was invented in 1879?

And then we have a lower biomass of carnivores, and a lower biomass of top head, or the sharks, the large snappers, the large groupers.

Pollutants like this derive mainly from the combustion of fuel in car engines.

Some people have estimated that the biomass tied up in these microbes

The plant biomass, the phytoplankton, the zooplankton, it's what feeds the fish.

Carbon monoxide is a poisonous substance formed by the incomplete combustion of carbon compounds.

The internal combustion engine took off because weight mattered, because you were moving around.

As a matter of fact, I invented the combustion engine and the twoway nappy.

From playing with it, they learn some basic principles about fire, about intake, combustion, exhaust.

What we did was we found what were the locally available sources of biomass.

Most of the biomass in the ocean is made out of creatures like this.

Most people don't realize it, because they're invisible, but microbes make up about a half of the Earth's biomass, whereas all animals only make up about one one thousandth of all the biomass.

Atmospheric explosions, or full combustion, takes about 15,000 times longer than what happens in your car.

They reproduce very slowly they have a slow metabolism and, basically, they just maintain their biomass.

If you put that same fuel in an internal combustion engine car, you get about 20 percent efficiency.

There have been hundreds of millions of internal combustion engines built, compared to thousands of Stirling engines built.

The top head does account for most of the biomass, in some places up to 85 percent,

And if we think about the increase of biomass inside the reserves, this is like compound interest.

First of all, your pyramid, your inverted pyramid, showing 85 percent biomass in the predators, that seems impossible.

But that doesn't help because there were very few species and volume of biomass there in the first place.

land use change, rate of biodiversity loss, freshwater use, functions which regulate biomass on the planet, carbon sequestration, diversity.

But after the Stirling engine, Otto came along, and also, he didn't invent the internal combustion engine, he just refined it.

Most of the biomass is low on the food chain, the herbivores, the parrotfish, the surgeonfish that eat the algae.

So, basically, the production surplus of these guys down there is enough to maintain this biomass that is not moving.

It's basically a measure of how many tigers, toads, ticks or whatever on average of biomass of various species are around.

So it's the same idea as a jet engine, it's just the heat source was the reactor rather than the combustion of fuel.

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

Then you go to Palmyra Atoll that has more biomass of herbivores, and the dead corals are clean, and the corals are coming back.

and we're making great progress for this goal is to have a propulsion system based on hydrogen and fuel cells, designed and validated, that can go head to head with the internal combustion engine we're talking about obsoleting the internal combustion engine and do it in terms of its affordability, add skill volumes, its performance and its durability.

The fuel cell looked great one tenth as many moving parts and a fuel cell propulsion system as an internal combustion engine and it emits just water.

A project that we've been working on very recently is to design a new biomass power station so a power station that uses organic waste material.

living in the pours and the cracks of the sea floor and below rival the total amount of living biomass at the surface of the planet.

And all the components are there which are now in common parlance, in our vocabulary, you know, 30 odd years later wind energy, recycling, biomass, solar cells.
