A lot of ideas have been proposed for alternative energy. However, looking at conditions here in Alaska, I wonder if any of them will work at the level needed here in an arctic or sub-arctic environment. Solar is out for about half the year and not much for the rest. Hydroelectric dams harm the fish populations, and don't work when the rivers are frozen. Wind farms harm birds, disturb wildlife with noise, use up large quantities of land, and only work when the wind is blowing. Add in the increased needs here with the need for reliable winter heating. Transportation is another, with most of the state accessable only by air, and those few roads sometimes going more than 80 miles between fuel stations. Lastly, add in the large distances in the state and the problems of transmission losses for electricity. Considering these together, is there a way alternative energy can prove effective in Alaska?

Here are 7 often-overlooked World Heritage Sites, each with its own history.
- UNESCO World Heritage Sites are locations of high value to humanity, either for their cultural, historical, or natural significance.
- Some are even designated as World Heritage Sites because humans don't go there at all, while others have felt the effects of too much human influence.
- These 7 UNESCO World Heritage Sites each represent an overlooked or at-risk facet of humanity's collective cultural heritage.
Famous physicists like Richard Feynman think 137 holds the answers to the Universe.
- The fine structure constant has mystified scientists since the 1800s.
- The number 1/137 might hold the clues to the Grand Unified Theory.
- Relativity, electromagnetism and quantum mechanics are unified by the number.
A new method promises to capture an elusive dark world particle.
- Scientists working on the Large Hadron Collider (LHC) devised a method for trapping dark matter particles.
- Dark matter is estimated to take up 26.8% of all matter in the Universe.
- The researchers will be able to try their approach in 2021, when the LHC goes back online.
