Each 300 mile (500km) Go-Tube is expected to require a large amount of engineered materials. These materials engineered and manufactured would be very expensive in small volumes, but with large volumes and patient development the cost per unit will be much more reasonable and ultimately compete with current technologies in price.

Early projections of carbon fibre required are 100,000 metric tonnes per 300 mile Go-Tube, which is roughly equivilent to annual worldwide production for all other purposes.

High strength, lightweight glass travel tubes and ultra-low reflectivity, tough outer glass panels are required. Depending on the strength to weight achieved, each 300 mile Go-Tube will require somewhere between 1/4 and 1 million metric tonnes of engineered glass. Glass has the strength, toughness and other qualities. Its weakness has been its crack propagation, that needs to be addressed.

Roughly 4 square kilometers of translucent Solar film using amorphous silicon or similar technology such as nanodots is needed to collect on the order of 100MW, depending on latitude and the specific technical implementation.

Transparent silicon rubber bracing holds the glass within the carbon fibre composite frame. Water based heat balancing storage keeps the travel tubes at near constant temperature through daily and seasonal temperature cycles. Power is efficiently transmitted from end to end of the Go-Tube and stored for overnight use in salt batteries. Data is transmitted end to end and used for communication by the passengers along the route and nearby highway travelers.
