If space is the future, sending a few people on the top of a burning Hydrogen+Oxygen rocket engine is expensive and dangerous.
We are proposing using the same Hydrogen+Oxygen paradigm to make something that is not as expensive, but still very dangerous.
Hydrogen for lift (balloon), Oxygen + Hydrogen for boost and the empty shell for a solar sail.
Even if we can only lift small weights out of the atmosphere, the cost would be significantly less than a rocket designed for warfare and modified for travel.
Photons as wave and particle
As you view a wave, all you see is the wave pattern,
but Photons dip deep below the wave to loop
into the next wave and appear to be a particle.
