It won't be very practical, right now it will work for some 10 times, 2-3 hours each, then you need to re-build the boat with new wood: >Li says that to date, the wood manages to deliver high voltage for about 2-3 hours, before it begins to wane. So far the wood has managed 10 cycles with water, without a decline in the material's performance, she says. >"The great advantage of this technology is that the wood can readily be used for other purposes once it's depleted as an energy source, such as transparent paper, wood-based foam and different biocomposites."
