The Popeye effect – powered by spinach

spinachPopeye was right; we can be powered by spinach! Researchers from the Technion-Israel Institute of Technology have developed a bio-photo-electro-chemical (BPEC) cell that produces electricity and hydrogen from water using sunlight, using a simple membrane extract from spinach leaves. The article, publish in the journal Nature Communications, demonstrates the unique combination of a man-made BPEC cell and plant membranes, which absorb sunlight and convert it into a flow of electrons highly efficiently. The team hope that this paves the way for the development of new technologies for the creation of clean fuels from renewable sources. The raw material of the device is water, and its products are electric current, hydrogen and oxygen.

Espresso fuel (Day 89)

Cooking FatDiesel, petrol and battery power are familiar ways to power our transport. LPG and natural gas are other alternatives.

But there are other more obscure (and sometimes less practical ways) to power vehicles.

Air, waste cooking oil, waste vegetables, beer and spirits, chocolate, nappies (diapers), sawdust, nuts, styrofoam and other waste or co-products all have the potential to fuel cars.

In fact, finding ways to convert industrial co-products into biofuel always seems a sensible and sustainable way to re-use our raw materials – especially for high volume commodities like coffee.
