Geothermal startup Mazama Energy said it drilled a borehole that set a temperature record. Such superhot rocks could make geothermal a key player in data center power.

Strong by Form has designed a structural floor piece that can span longer distances than existing engineered wood, making it a replacement for steel or concrete. At the same time, the product is lighter than all three.

MacroCycle's approach to recycling dramatically reduces the amount of energy needed to produce new material, potentially lowering costs to the point where it could compete with virgin plastic.

As demand for electricity from data centers grows, Arbor Energy has made its power plant capable of burning natural gas in addition to biomass.
