Zenman Energy is working on developing and prototyping an open source concentrated solar thermal/steam power generation application.

Our first major project is to produce an affordable solar steam engine. On paper (well… on computer screen) our first design is a fraction of the cost of current photovoltaic solutions. It may even compete with the cost of coal power. When the prototype is complete, we will release detailed construction plans for free.

This may sound strange, but we WANT you to copy our designs. First, we need help to improve the implementations but more importantly we need YOU or your business to make money from solar power production. Zenman Energy can’t create enough power plants to make a dent in how the world creates energy, it will take lots of people to make this happen.

We are not doing this for the money…
