As those who live in Northern Latitudes know, this time of year the sun does not rise in the east. The sun traces a long arc from the NE to the NW. A solar array pointed south would not achieve the benefits of the very long period of almost 17 hours of daylight.
Eastern Oregon typically has 300 days
of sunshine per year, so solar power may be an option. This area also boasts a large number of Shield Volcanoes.
I propose a solar array on rails that would be placed on a shield volcano. The railway would have switchbacks which correspond to the sidereal sweep of the sun. Each day, the train would follow a sloping track to follow the sun. At dusk, the solar array would swing back to catch the morning rays.
Underneath the train would be a cogway that would be used to send the collected power out to the grid and to provide power to drive the solar array after the summer solstice.

This is interesting, but sounds excessively complicated and inefficient, especially if the train has to buck a wind to move. |
|

The wind would only be a factor after the summer solstice. Otherwise, it's downhill all the way spring into summer. |

This IS the HalfBakery, isn't it? |

Hmmmm. . .verrry interesting! And no more complicated than trying to make fusion energy work.
Like it :)! |

Power the locomotive with geothermal energy from the volcano, Shirley?! |

Better to just carry on round to the start point ? Shorter to go on than back ..... |

[8th of 7] You're right. That would be the shorter journey, at least during the longer days of summer. During the winter months, the rails would be the switchback. |

It would take much less energy and is much simpler just to have the solar panels on a tracker. This is already well established technology. |
