Teaspoon Passive Cooling

Just like a silver teaspoon protects a cup from breaking (when you pour boiling water into it), so when a spacecrafts enters the atmosphere, we can use a very conducting material that will conduct the heat to a radiator behind the spacecraft (instead of a ceramic heat shield).

Fractal Lichen

The best way to make oxygen on Mars is with cyanobacteria, we maximize their surface using 3‐D fractals.

Mass Driver Repeater

An efficient system to send packages (not people) between planets by connecting the idea of a repeater (from telecommunications) to the idea of a mass driver (from non‐rocket spacelaunch / spacecraft propulsion).

External Dynamo

generating a magnetic field for Mars using an orbital ring made of metallic asteroids which are driven like "clay pigeon shooting" with a laser instead of a shotgun.

Meteorites Water Cannon

Protecting Mars colony against small asteroids using hydrostatic pressure.

Space Escalator

facilitating a "space elevator" for 1 Kilogram weights by splitting it into many independently floating sections.

Space Junk Decelerator

slowing down space debris by regular ice (water) or by dry ice (CO2). and concentrating the ice in the projected projectile path without touching the ice, by optical / electrostatic / microwave levitation.

Lenz Law Navigational Deflector

protecting spaceship from space rocks with a force field using Lenz's Law.

Nitrogen Fluorine Hydrogen Alien Life

astro-biologists look for for signs of extra-terrestrial life assuming that aliens are built like us (search for water carbon etc). i show a different possible model for life based on other building blocks.
