I too agree that bitcoin is like the Ford Model T- a game-cha nging breakthrough that was eventually improved upon. Bitcoin attracting more miners to use more energy as the price of BTC goes higher is obviously sub-optimal.

However, there are already a number of coins that are much more energy efficient than bitcoin. While I applaud your efforts, I believe your idea to effectively burn/reduce the circulating supply of BTC will push up the value which only encourages more miners which increases the difficulty formula- more miners and upward difficulty adjustment both result in more energy use, not less. You'd be better off selling the btc and using the proceeds to support the price of your own coin (or buy carbon offsets, or campaign for a carbon tax or any number of other things).
