Here’s how to mine bitcoin free:
- Build a small brick chimney, put a thick iron wok on it, let coal/wood burn under it.
- Put pure cleaned silica and place in sunshine
- Get a powerful blow torch and melt the sand
- It will start forming glass at the bottom
- Once mostly done, place a red hot thick smaller wok on top of the last not melted glass.
- You now have a lens like your eye lens
- Polish it to perfection
- Keep making new ones until you get super clear thick glass
- Once ready, put on a stand out in the sun, around 10 AM to 3 PM it will direct direct-sunlight directly to water under it, the water will heat very fast and boil and steam
- Convert continually generated steam to electricity.
- Mine bitcoin!
