I agree, let's move the building to Central Park! Will you start the Kickstarter campaign or shall I?
PS: Long Island is the most populated island in the US, it has 7.6 million inhabitants. Also, Brookhaven is in the middle of the island (close to Fire Island), not the far end. The Hamptons are way farther out, and yet plenty of people manage to find their way there.
When you exclude Brooklyn and Queens, which are ~70 miles away from this site, Long Island has only (7568304 - 2532645 - 2247848) = 2.8 million residents. And that 70 mile distance will be far enough out of the way to exclude most out-of-area tourists who are visiting NYC.
The site significance is cool, no doubt, but I question how many people will ever trek out to visit this.
Eh, 70 miles is still daily commuter distance; there are thousands and thousands of people who commute daily from 70+ miles away in Long Island, Connecticut, New Jersey, Pennsylvania, and Upstate to Manhattan.
A good science/history museum there would still be in range of the informed tourist (ie, those likely to spend a day at a Tesla museum) and more importantly of elementary school field trips. Personally I would pair it with the Teddy Roosevelt museum on Long Island and do a Turn-of-the-Century Internet Celebrity Day Trip.
