Southwest Research Institute (SwRI) developed an inexpensive light weight hollow aluminum sphere that when cast into typical syntactic foams further reduces the weight of the foam, and allows for a reduction in the size of the bouyancy block on a deep or ultra deep water ROV. Using this technology with a 3000 meter water depth rated syntactic foam, SwRI was able to achieve bouyancy block densities as low as .406 kg per cubic meter with an efficient packing of the sphere.
