Sanza Kazadi: Making Sustainability Cool!

<p>This week we spoke with Sanza Kazadi, Founder of Kazadi Enterprises. Kazadi Enterprises is developing refrigeration systems that use the cleanest energy on earth - environmental heat.  Their systems reduce the energy cost of refrigeration by up to 90% and eliminate greenhouse gas emissions from refrigerants. Sanza discusses how their solutions are resilient against brown- and black-outs, working even when electricity isn't available. </p>
