atmospheric phenomenon? What causes condensation trails to converge? ...forgot to accept your answer. The aircraft design and resulting vortices seem crucial. |

atmospheric phenomenon? What causes condensation trails to converge? Anna, I agree. Whenever we are talking about atmospheric effects, observed over hundreds of meters, optical effects must be considered, even more so when we are talking about non-adiabatic cooling in the contrail formation. Notwithstanding the sun's position and the camera lens distortion and plane-"glow", etc... I failed to mention that I did observe the described contrail-shape with quite some consistency over varying angles of ascension and declination. Great photos, btw! Good explanation, but I am not quite satisfied yet... |

What is the most energy efficient way to boil an egg? @MartinBeckett Your case is harder to calculate, then ohmic heating. I reckon a typical vacuum pump gets exponentially more inefficient as it reaches its min-pressure threshold limit. There are also two[sic!] very different phases (egg-shell excluded) - the reason for microwave-egg explosions. Carl, the egg is currently accelerating at 10m/s towards earth and doesn't bring itself into orbit ;) Lastly, since almost all energy was of solar origin, and we are subject to an open system, I would argue for a solar cooker |
