Your old windows are costing
you tons in extra heat and air

Don't keep spending so much on electricity- you could get new windows that could also improve the look of your home and also potentially increase your homes value.

Spot, for all its long duration, is mobile and inconstant, and is therefore no portion of a solid permanent crust. The giant planet Jupiter, therefore, offers us an 131 example of what we may call a semi-sun; a world still bubbling with tremendous energies of its own, still pulsing with its own inherent heat, still without a solid crust; probably without a solid nucleus, liquid or vaporous throughout. Whatever the future may hold for such an orb, it is clearly no world for habitation at present. Jupiter therefore introduces us to a new factor in world-condition; not all its heat is derived from the Sun; much is inherent to it. And though it is not possible at present to say that the mass of Jupiter being so much its inherent heat must be this or that quantity as a function of that mass, yet in general, and neglecting other considerations, we can say that of two worlds the Jupiter is not to be disputed. The albedo or reflective
index of Jupiter has been put by the late Prof. G. Bond, of Harvard College Observatory, as higher than unity; in other words, that it emits more light than it receives. This is now generally regarded as an excessive estimate, but the albedo of the disc as a whole cannot be put lower than 0·72, or about that of white paper. But many of the belts or 128 dark regions are of a dull copper tint, and the polar caps are dusky, so that Bonds estimate

Sun presents to the Earth, but to make up for the falling-off of the solar radiation, each unit of this area should radiate about 1⁄250th as much heat as each unit of the Suns surface. In other words, the absolute surface temperature of Jupiter should be ¼th that of the Sun, or about 1550 C., and this is higher than can be admitted. The Sun and Jupiter together cannot put Ganymede in as favourable a position as Mars, much less as favourable as the Earth. The case of Jupiter carries with it those of Saturn, Uranus, considered; the other four are of the same order of size as the asteroids, and are indeed much smaller than Ceres. But the Galilean satellites are of a higher rank. Europa, the smallest, is in size a twin to the Moon; Callisto, the outermost, is almost exactly the size of Mercury; Io, the innermost, is midway between the two in its dimensions. But Ganymede, the largest, one-tenth scale, the
surfaces would be one-hundredth of reality, the volumes one-thousandth. But a radiating body radiates from its surface, while the store of heat from which that radiation is kept up is supplied by its volume. It follows, therefore, that a large and heavy world must differ from a small light world, not merely in scale, but also in kind. The surface of a world is
