Author has designed, studied, used at home and published for more than 40 years the performance of various hot box solar cookers, including hybrid and multipurpose solar ovens. The objective here is to study two vacuum solar water heating tubes, for heating air, water and for cooking meals and pasteurizing water etc., to see its thermal performance and make some comparison with conventional hot box solar oven. Air, water, meals temperature and solar intensity is measured. On sunny day, maximum air temperature reached to about 220 ⁰C and water temperature to about 96 ⁰C. Different vegetables, lentils and including pork pieces were cooked. In addition, for first time author used cheap, portable, battery operated smart camara and mobile phone to measure solar intensity and temperature remotely, even at coffee shop.
