Deep Ocean ROV using a Glass Sphere Pressure Housing


Here is some updated information on a very interesting full ocean depth capable vehicle which is now being commercialized by a company in Norway. The actual glass sphere housings cost around $1000 - $2000 depending on size and number of penetrations required, but to get one that is optically polished adds another $5000 to the price. To my knowledge with the recent demise of Nereus, this is one of the few operational vehicles capable of reaching these depths.
