Re: Steam powered rovers

I got thinking about the co2 collection and here is what I was thinking.
A repost:
I got thinking about how to concentrate the intake of the co2 inlet for the compressor to be able to move it to a storage tank but under higher pressures. The through put was to be created on a circular track or road for a solar power rover to just drive at velocity with a funnel shaped opening to use as a ram intake to boost the incoming pressure to allow for a compressor to work more easily.

Basically using a rocket engine nozzle in reverse to create a greater pressure via motion.
Storing on the vehicle to be released to a much larger tank when its its stopped.

Re: Steam powered rovers

Using mars against its self to make energy from the day time solar and night time cold would mean that we would use 2 systems to collect the energy and a 3rd to create energy for mans use with the other.

Lets make use of an evaporated tube for collecting the heat Which is dark or black in color, using an inlet control value to allow mars air to enter during the night and have it close at the dawn comes with. The exit valve that is set for the high of the days pressure to allow for a bank of these to make a heat engine.It would be possible to do a solar powered value for the injecting process.

Several of these could be mounted to a manifold to gang the pressure to push a rotary or piston style shaft generator system where by the vented gas from motion exits to a low pressure tank for the next days use.

The other night time collector which is an open shiny relective group of tubes to store cold co2 would cool the exit gas to make dry ice from it.

Of course the shafts of opposing drives are 180 out so as to push pull the complete cycle of motion. This is simular to the locomotive steam engine in concept.

Another mixed topic of energy, co2 compression and movement by them...
