SECRET STORES OF ENERGY.

PROFESSOR EDDINGTON'S VISION.

THE UNSOLVED RIDDLE OF THE UNIVERSE.

But we must allow for the fact that the sun "will become leas spendthrift in its old age"; and its life as a waning star might be prolonged much beyond 15 billion yetirs.

A. S. Eddington addressed the World Power Conference on "Sub atomic energy." I am going to tantalise you," he began, with a vision of vast supplies of energy far surpassing the wildest desires of the engineer-resources so, illimitable that the idea of fuel economy is not to be thought of. The energy of

thing to say as to the conditions of release of sub-atomic energy. The answer appears to be quite definite, yet one cannot help regard ing it as incredible. The answer is that if you want to tap any really large supply of sub-atomic energy you must heat matter up to temperature of 40,000,000 degrees (Celsius). I will not guarantee that 40,000,000 is exactly the right gure. It may be 30,000,000 or perhaps a little less; but my poins is that there is a definite tempera türe somewhere about this magni- tude at which matters,„seems to yield up its energy prolifically, whereza a few million degrees lower the yield is practically nilIt is almost like a boiling point.

Energy in a Drop of Water.

"Einstein has shown us how to calculate the amount of energy stored away in matter-sub-atomic energy we call it. There is enough energy in a drop of water to furnish 200 horse-power for a year,

And this revelation of what is going on in the astronomical universe has core not by looking through a big tele scope but because it was noticed GRAND HOTEL DES WAGONS, that gold leaf electroscopes were never perfectly free from leak, how ever carefully they were shielded from all familiar sources of ionisa- tion.'

That puts the problem of 'ra- lease of the sub-atomic energy in a new light. Just now we thought. we had found the key. The thing to do was to heat up matter to .40,000,000 degrees, at which tem "perature it seemed likely that sub- atomic energy would issue forth in abundance. Now it appears that it is also given off in the diffuse clouds of inter-stellar matter which, even if it is not (as used to be sup-. posed) at a temperature below that of liquid hydrogen, has certainly no very remarkable degree of heat.

We build a great generating station of, say, 100,000 kilowatts capacity and surround it with wharves and sidings where load after load of fuel is brought to feed the monster. My vision is that same day these fuel arrangements will no longer be needed; instead of pampering the appetite of cur engine with de- licacies like coal or oil we shall induce it to work on a plain diet of sub-atomic energy. If that day ever arrives the year's supply of fuel for the station will be carried in a tea- cup-namely, 30 grammes of water- or of anything else that is handy. The Possible Lite of the Sun.

After showing the fallacy of the theory that the heat of the sun is kept up by meteors falling into it, Professor Eddington showed that the source of energy must be at or near its centre, where the tempera- ture was calculated to about
