There's very little likelihood that the aluminium powder (or whatever form it takes) that is consumed in your reactor can ever be sensibly 'renewed' in your backyard.
Perhaps, if all fossil fuels are off limits for your homebrew fuel-savers, then maybe check out (old) technologies like wood-gas and similar alternatives.
Though I expect we agree on much of the wider politics behind this, there is still a practical and economical limit to which of the multitude of emerging techs will help us replace oil, gas & coal... and IMO this ain't a good candidate.
