Looks like Danish sushi to me.

It is nice to know that something as antiquated as bound books are finding a new life as quaint decorations for bars and restaurants.

A galvanic pile is a series of alternating metal plates separated by an electrolyte. Such constructions will produce electricity and are an early form of battery.

Electrons travel from one type of metal to the other while atoms of metal travel in the opposite direction. If the electricity is drained very slowly, good piles can last a long time and will continue to provide electricity until one type of metal is completely used up.

No new science here, just a very efficient "motor".

Show someone an effect and he will invent a cause.

Really neat, but for 40 dollars in parts he could have built in a proximity sensor so it really worked like the Star Trek doors.

Very well done. Thank-you.
