Vesta

With 120 intensities of the sun, the Vesta reaches 400°C and delivers 1800 Watts.

That’s enough power to bring a liter of water to boil in under 5 minutes, at no fuel cost.

To understand what the Vesta can do we must consider 6 things: 1 - Free Energy 2 - Temperature 3 - Power 4 - Efficiency 5 - Location 6 - Uses Free Energy Since sunlight is free (for now), once a Vesta is built it provides free energy. So, a straight comparison to other stoves and ovens is misleading. A gas or wood stove (...)

Comparing the Vesta v2 and the Batant v1 Batant Construction Guide v1 Vesta Construction Guide v2 Design differences The Batant and Vesta are virtually the same except for size (the Batant is 1x1m and the Vesta 2x2m). However, many different techniques can be used to arrive at the final result, and the guides display this variety. The techniques shown in the Batant can be used in the construction of a Vesta, and vice-versa. So it’s a good idea to look at them both carefully and choose (...)

However, newer doesn’t necessarily mean always better, and so we recommend taking a look at the differences between the Batant v1 and the Vesta v2 before taking a look at the Vesta v2 guide. The Vesta v2 Construction Guide should (...)
