Two of the biggest hurdles for using wind power have been cost and the need for strong winds. A Hong Kong businessman/inventor has found a way to overcome those problems with plastic, bringing the generation cost down to around 1 cent per kilowatt-hour — the cheapest wind power system available on the market.
The inventor, Lucien Gambarota, sought to find a wind energy solution that could be feasible and affordable for remote third world villages and urban settings, where towers are not practical or allowed. The typical wind speed in such settings is between two and seven meters per second.
The return on investment is between three and five years.
“Motorwind power generation starts with 2 m/s wind speed but it starts to be economically viable for winds of at least 4m/s if you are concerned by pay back time.” It can be installable anywhere due to the modularity. The size of Motorwind can be adapted to the available space and the energy required. The design simplicity and components used make the installation and maintenance very easy for anyone. The simplicity allows very low manufacturing costs and therefore very low retail price.”
