We have seen wooden mice and wooden keyboards so why not a bamboo calculator? Such would be perfect for the folks who are pretty much concerned about the environment, something which is solar-powered at that.
Especially for the businessmen or people who often need to do some computing wherever they may be, the Solar Powered Bamboo Calculator stands to be a better alternative to the usually plastic-based ones available in the market.
The display can showcase up to 12 digits and shuts itself off after 12 minutes when not in use. The bamboo calculator can only be used for simple math equations and not complex algebra problems.
