Strong Propulsion

Discount Kids Bound Urban Rebounder Series - ... The kids are exercising and having FUN and their feet barely leave the mat. They don't bounce high, they bounce strong, limiting their propulsion, pushing down with their feet rather than jumping up. First Timers In first-timers, the kids ...

It has the potential to make space travel as inexpensive as train travel. There ...

Antimatter catalyzed nuclear pulse propulsion -     Home Encylopedia Directory eShowcase Sitemap Privacy Contact Us Enyclopedia Home | See live article   Antimatter catalyzed nuclear pulse propulsion Nuclear pulse propulsion has the downside that the minimum size of the engine is defined by the minimum size of the nuclear bombs used to create thrust. With conventional technologies these bombs can scale down to about the kilotonne range, but making them smaller seems difficult. These large bombs require a heavy structure for the spacecraft, and a very large (and heavy) pusher-plate assembly. A new technique is changing the nature of this equation considerably. By injecting a small amount of ...

Field Emission Electric Propulsion - ... and an accelerator electrode. A potential difference on the order of 10 kV is applied between the two, which generates a strong electric field at the tip of the metal surface. The field extracts ions, which then are accelerated to high velocities ...

Dinghy - ... pieces while off-shore. When the joining method was sturdy, these reported good results. Essential hardware A dinghy should have a strong ring on the bow, bolted through the keel in a position that will not score the yacht's deck when ...

Nuclear fusion - ... opposes the fusion reaction. The long range Coulomb repulsion between the nuclei is offset by the stronger but short range attractive strong nuclear force. The problem becomes one of bringing the nuclei sufficiently close for the strong nuclear force to be strong enough that the Coulomb barrier can be passed through tunneling. The magnitude of the repulsion of the nuclei depends ...
