Helium-3 is proposed as a second-generation fuel for nuclear fusion in hypothetical fusion power plants, but such plants are still very early in their development -- especially since the first generation has not entered service anywhere, yet.

Helium-3 has a negative enthalpy of fusion at temperatures below 0. 3 K. Helium-4 also has a very slightly negative enthalpy of fusion below 0. 8 K. This means that, at appropriate constant pressures, heat must be removed from these substances in order to melt them.

Helium-3 has a negative enthalpy of fusion at temperatures below 0. 3 K. Helium-4 also has a very slightly negative enthalpy of fusion below 0. 8 K. This means that, at appropriate constant pressures, heat must be added to these substances in order to freeze them.

Helium-3 has a negative entropy of fusion at temperatures below 0. 3 K. Helium-4 also has a very slightly negative entropy of fusion below 0. 8 K. This means that, at appropriate constant pressures, these substances freeze with the addition of heat.

Helium-3 is also thought to be a natural nucleogenic and cosmogenic nuclide, one produced when lithium is bombarded by natural neutrons.

Helium-3 was trapped in the planet when it formed.

Helium-3 ( He-3, sometimes called tralphium ) is a light, non-radioactive isotope of helium with two protons and one neutron.

Helium-3 was hypothesized to be a radioactive isotope until helions were also found in samples of natural helium, which is mostly helium-4, taken both from the terrestrial atmosphere and from natural gas wells.

Helium-3 boils at 3. 19 kelvin compared with helium-4 at 4. 23 kelvin, and its critical point is also lower at 3. 35 kelvin, compared with helium-4 at 5. 2 kelvin.

Helium-3, however, is a fermion particle, which can form bosons only by pairing with itself at much lower temperatures, in a process similar to the electron pairing in superconductivity.

Helium-3 propulsion is a proposed method of spacecraft propulsion that uses the fusion of helium-3 atoms as a power source.

Helium-3 is proposed as a power source for spacecraft mainly because of its abundance on the moon.

Helium-3 is also produced via beta decay of tritium, which in turn can be produced from deuterium, lithium, or boron.

Helium-3 is necessary in the fusion reactors that provide energy for virtually all electric systems, including the energy patterning nodes essential to the interstellar ZTT ( zero-temporal transit ) drive.

One suggested trade commodity, Helium-3 ( He-3 ) from the solar wind, is thought to have accumulated on the Moon's surface over billions of years, but occurs only rarely on Earth.

Helium-3 is created by cosmic ray bombardment, and by lithium spallation reactions which generally occur in the crust.

Longshot would have a mass of at the start of the mission, including 264 tonnes of Helium-3 / Deuterium pellet fuel / propellant.

Helium-3 occurs as a primordial nuclide, escaping from the Earth's crust into the atmosphere and into outer space over millions of years.

Helium-3 can be used in instruments for the detection of free neutrons, such as neutrons leaking from nuclear reactors.

Such colonies could export Helium-3 for use in fusion reactors if they ever become practical.

Helium-3, an isotope of helium with two protons and one neutron, could be fused with deuterium in a reactor.

The race problem has tended to obscure other, less emotional, issues which may fundamentally be even more divisive.

The fact that he has cast over those materials the light of a skeptical mind does not make him any the less Southern, I rather think, for the South has been no more solid than other regions except in the political and related areas where patronage and force and intimidation and fear may produce a surface uniformity.

The young William Faulkner in New Orleans in the 1920's impressed the novelist Hamilton Basso as obviously conscious of being a Southerner, and there is no evidence that since then he has ever considered himself any less so.

Our surplus from foreign business transactions has in recent years fallen substantially short of the expenditures we make abroad to maintain our military establishments overseas, to finance private investment, and to provide assistance to the less developed nations.

Ramillies And The Union With Scotland has fewer high spots than Blenheim and much less of its dramatic unity.

Everyone is more or less sceptical and virtually no one has been willing to accept Lappenberg or Kemble's position on that point.

Mr. Goldberg has less reason for missing.

Dr. Linus Pauling, a Nobel Prize winner in chemistry, has been less ambiguous, whether you choose to agree with him or not.

But more than one conscientious researcher has been inhibited from completely frank discussion of the available evidence by the less excusable fact that fallout has been made a political issue as well as a scientific problem.

It seems to me the time has come for the American press to start experimenting with ways of reporting the news that will do a better job of communicating and will be less subject to abuse by those who have learned how to manipulate the present stereotype to serve their own ends.

A minor who has gross income of less than $600 is entitled to a refund if income tax was withheld from his wages.

it has been estimated that spending by the National Aeronautics and Space Administration will rise from less than $500 million in fiscal 1960 to more than $2 billion by 1967, and that the electronic industry's share of these expenditures will be closer to 50% than the current 20%.

But having lived with the disc for some time now, I find the performance less exciting than either Schnabel's or Fleisher's ( whose superb performance with the Budapest Quartet has still to be recorded ) and a good deal less filled with humor than Curzon's.

This has saved us from constant requests seven days a week and made us feel less brutal to the young `` less fortunate '' than ours.

A stream which has all of its watershed within a national forest or other lands under good conservation practices is less likely to be affected by pollution than one passing through unrestricted logging or past an industrial area.

For one thing, the driver usually sees less and has less fun than his passengers since it becomes pretty necessary for him to keep at least one eye on the road.

Another less ambiguous case read as follows: `` The bearer of this letter has served me for two years to his complete satisfaction.

To a much less full extent, the hebephrenic person's belching or flatus has a comparable communicative function ; ;

The design of orthographies has received much less attention from linguists than the problem deserves.

And he has proclaimed greater or less affiliation between all Western hemisphere languages.
