Eco toys & gifts for kids, from simple beads that change colour in the sunlight to temperature driven Stirling engines. Each eco toy is operated either by solar power or by other types of green energy.
Colin Just to pass on my thanks, unit works superbly for my needs, doubling time between engine starts for charging. Advice and product are great, thank you.
