Yes it's rubbish. The experts admit these new food production methods will take huge amounts of electricity, but say it will all be from renewables so it doesn't matter. However surely conventional farming will also have access to this virtually free and 100% renewable electricity? Before long nitrogen fertiliser will no longer require fossil fuels for manufacture, machinery will be electric so no emissions, drones and breeding advancements will increase yields and eliminate the need for chemicals.They haven’t got a clue.
Wheat yields increased 220 to 300 times the global average of 3.2t/ha by moving to vertical production ?
If we’re allowed to follow their ‘man maths’ bullpoo ideas, that would be a yield of 700 to 960 t/ha (average 830t/ha).
Even at the world record yield of 17t/ha, if you divide one by the other you reach the conclusion that for an annual wheat crop the vertical farm would need to be 49 stories high.
For a biannual crop still at WR yield, 25 stories high.
How much concrete, glass, copper and steel and AND CO2 would be required to manufacture Chris Starks ‘Towers of Babylon’, never mind the CO2 released to generate the light and heat energy to keep them going? LED’s are efficient, but they don’t power themselves.
Ive skipped through this thread because the arrogance of the CCC pisses me off. But if this is what the CCC *IS* correct, then Chris Stark should resign over his continued demands for the impossible, and slander against an entire industry.
These reports are a joke because they don't compare like with like. They compare future methods of food production using future technologies with current farming practices using current technology. They don't allude to the fact that conventional farming will also progress rapidly as time goes by, probably eclipsing the theoretical benefits of these new methods
