Only 5 feet MAX? Get back to me when they can to 20-30 feet with no problem. (deeper would be better.)

its very bouyant. it was on the gadget show a while back. when you dive it clearly wants to surface which is why it is able to leap out of the water.

That just means it needs a bigger engine; more thrust.

:D

It wouldn't be too hard to fit the thing with some SCUBA gear; one tank for you and one tank for the engine...

Now that would be badass.

well no because when it goes under at max depth it starts to breath your air...the engine breaths ur air:p the presenter said he felt the air pressure drop immediately when it happened.

u cant do that for long. its hard enough to keep something water tight at high speeds just 5 feet underwater anyways, if you were to add impact resistance and further depth capability the walls would have to be very thick. it would rather quickly become an engineering nightmare.

That's why I said the engine needs its own oxygen tank.

And it wouldn't be an engineering nightmare to make it capable of ~25ft. Much more complicated than the current design, but certainly feasable.

They could make a killing renting them out during tours of reefs and such. That would be badass.

Uh? For the engine?

???

If you're diving under water, how is the engine going to breathe without an oxygen tank?

Wouldn't even be hard to setup a flow regulator based on throttle position.
Do you know how much oxygen an engine needs?

well stationary 25feet pressure is different from 25 foot pressure at high speed.

its why those depth ratings on watches tend to be bs.

No matter how much it seems like it would be cool, in the end, you're still a dude in a dolphin...

Why is everyone going after internal comustion engines? Just about all feasible subs are based on electric drive, whether diesel electric to chage batteries on the surface or nuclear electric so it can always be submerged. Give this thing a electric motor, batteries and a small diesel generator and you're set.

Of course I do.

A 600CC engine would need 54CFM at 6,000RPM assuming 85% volumetric efficiency at wide open throttle.

Obviously your average in the real world would be less, since you wouldn't be at WOT all the time.

Hmm. So from a little research, it appears that the most common size SCUBA tanks are either 72 or 80CF. With that big of an engine, they wouldn't last very long - I assume you would have to use a larger one.

Another option would be to have an onboard compressor to refill your engine's SCUBA tank. You would have to surface every X amount of time to recharge your air supply.

I'd be down with that. Obviously such a submarine would significantly outclass this one in both technology and price, but I think it would be really cool.

That's a very good point. :thumbsup:

That's much more simple than my idea.. Give it some LiIon or at least NiMH batteries to help keep the weight down, and rock on! :D

If you combined our ideas, you could potentially stay under water for twice as long without having to resurface.

Where's the laser? I didn't see no laser. Aren't dolphins supposed to have lasers?

well the market for these is people who can probably afford both;)

massively increase cost, weight with that setup. its a small recreational vehicle, not a military sub.

This. If you want a personal sub and have tens of thousands to spend, spend it on this. Good to 50 meters.

you're not going to pick up on dolphin chicks in that thing though ;)

The dolphin ride would be amazing if you could go deeper. If I were to get one I'd probably get the one that went down quite a bit further :p

It's a small gimicky recreational vehicle that I'd bet people would get bored of pretty quickly. And, it seems to be little more than a reshaped, ride-in (rather than ride-on) jet ski.
