Hey, yesterday we visited a coupla groups doing some realistic new stuff regarding energy production.
We visited Xjet Solar, whose innovations involve new ways to do solar cells very cheaply, which is a big deal… using some new proprietary tech. This is a photovoltaic solution, wherein light is converted directly into electricity. The focus is on small applications, like powering a home. While promising, it's a future.
We also visited Solel which uses existing tech to use thermal energy. That is, this uses the sun's heat to create electricity using turbines. It's another way to generate steam to get power. It can be used at power stations, like one that might be at the Mojave Desert.
This tech is here and now, and power stations are being built.
It uses arrays of parabolic mirrors which follow the sun, focusing on glass/steel tubes wherein the hot water is generated. The first photo shows a mirror, with the black line being the tube which concentrates heat. The second photo shows a stack of those tubes close up.
