Pete Schwarz speaking at the SCInet Solar Cooking Convention 2014
Pete Schwartz, Professor in the Physics Department at Cal Poly San Luis Obispo, California, USA.
In 2015, Pete Schwartz' students invented ISEC (Insulated Solar Electric Cooking), building the first prototype in three days before driving it to the Solar Cookers International conference in Sacramento, California to roast a chicken stew. Since then, they have continued to collaboratively develop and disseminate the technology, adding a USB charging port and Heat storage capacity with erythritol phase change material (PCM). Collaborations are often built through our appropriate technology classes and includes a company that they started in Ghana in August 2019 funded by MECS. Read more at the ISEC research page.
Pete's involvement with solar cooking began in 2007, with particular interest in Scheffler Reflectors and other polar tracking heliostats, but changed to solar electric cooking after extrapolating the decrease in solar panel costs.

HighPower ISECooking-2
We boiled a liter of water in 2 seconds. prototyping our new Insulated Solar Electric Cooker at the workshop in Togo. corresponding to 100 kW, like 100 times the power of a microwave oven. Then we recharged it for an hour and dumped in 1 kg of veggies and finished a stir fry in about 2 minutes

Insulated Solar Electric Cooking with Thermal Storage, EWB Sweden, Pete Schwartz, Cal Poly Physics-2
Pete Schwartz presents his team's latest findings, as they develop different approaches to insulated solar electric cooking. He predicts an eventual decline in the use of phase change materials (PCMs) to retain the heat for cooking, as batteries become a more efficient and less expensive way to store energy. This may happen in the next ten years. In the meantime, a solid block of aluminum is showing promise as a simpler way to store heat compared with PCMs.
