Roof garden
The easy way to convert your roof into a microcosm | |
You will need the following.
1) Solar panels
2) Mircoreactors (edit)
CO2 + 4H2 -> CH4 + 2H2O
CH4 -> CH3OH
3) Electrolysis cells (edit)
2H20 -> 2H2 + 202
4) A collector (perhaps from your dads still)
5) Roof mounts, fittings,
2 lengths of tubing and a ladder.
Check the net (or a local moonshiner) for your nearest stockest.
Install your artifical roof garden as follows.
1) Attach your solar panels, microreactors and cells to your roof. Remember always get the permission of an adult before using a ladder.
2) Put your collector in a convenient location near the house and attach using your first length of tubing.
3) Attach a water supply to the electrolysis cells and duct the hydrogen (at the cathode) to the microreactors using your second length of tubing.
All done... your roof garden will produce oxygen and alcohol just like a real one would... (if your dad is a moonshiner)

Ha !, the last paragraph's a inflammable cracker. |
|

I have no idea how this works... mainly because I'm thick... but I would gladly swap our prize cow for he magic beans that made my roof into a distillery. |
|
| |
The magic is heat and electricity... the solar panels provide energy to the reactants and the result is moonshine! (and O2). The electrolysis uses electricity and the micoreactor uses heat. |
|
| |
The microreactor chemicals in their new high energy (heated) states are more likely to combine as alcohol and oxygen than carbon dioxide and hydrogen. The new bond energies are higher since they have retain some of the heat energy provided by the reactor. |
|
| |
The reactor is just a small box containing a catalyst that brings the reactants together at the right temperature. The chemicals just do whatever they think is best at that temperature. |

//2CH3OH// Methanol is not good drinking. |

OK, so this produces a toxic alcohol,
but it's an interesting way of storing
solar energy. It would probably be more
efficient if you found a way to split the
water molecules using the sun directly
as solar panels are, on the whole,
horribly inefficient. |
|
| |
Yeah interesting in as much as it copies grass and the like... |
|
| |
The micro reator requires a constant supply of Hydrogen --- and no heating --- as the Sabatier process is endothermic and once started will continue until all the Hydrogen is consumed. |
|
| |
Hence the electrolysis... |
|
| |
I figure the Hydrogen should be produced during the day and consumed at night --- sort of mimicking a plant... |
