  • THE podcast for everything clean tech

    Silas and Somil do a wonderful job of extracting real insights and stories - not scripted answers. The guests and their companies are eye opening, and I would recommend a listen to anyone who’s vaguely curious about what’s being done to build a better Earth.

Talking Points

Recent interactions between the hosts and their guests.

#281 Simplifying Heat Pump Rebates | Samir Pendse (Coral)
Q: What evidence do you have of traction and growth since launch?
Contractors using Coral see a 20% to 30% lift in sales conversions when offering instant rebates, and the company has completed thousands of projects with a 100% repayment rate on rebates.
#281 Simplifying Heat Pump Rebates | Samir Pendse (Coral)
Q: How do you actually make money in this setup?
Coral takes a small percentage of the rebate amount as a fee and the contractor gets the rest, effectively pricing in the value of the instant rebate and the automation/filing services.
#281 Simplifying Heat Pump Rebates | Samir Pendse (Coral)
Q: Got it. So can you explain just the basic mechanics of how that works for a homeowner wanting a heat pump?
The HVAC contractor offers a heat pump and Coral enables instant rebates by advancing the rebate funds upfront; Coral handles filings and financing, so the homeowner pays less upfront and the contractor is paid immediately through Coral's rebate financing and then connected to the best financing plans to minimize monthly payments.
#280 Why Every Company Will Decarbonize & The Climate Investment Arbitrage | Andrew Beebe (Obvious Ventures)
Q: What are the core things driving more adoption of clean technologies today?
Beebe points to a combination of electrification in vehicles, industrial decarbonization, and AI-enabled efficiency, with utilities planning large-scale grid scaling and a push for decarbonization across sectors, supported by falling costs and international policy shifts.
#277 The Battery That Lost the EV Race but Could Save the Grid | Antonio Baclig (Inlyte Energy)
Q: What are the other applications that you think are most likely to benefit from this specific chemistry in the immediate future?
Antonio mentions residential storage solutions and some industrial applications may benefit significantly from iron-sodium batteries.
