saying we need produce more waste to recycle car batteries is like saying we need more CO2 emissions to actually cause more climate change so no can pretend it does not exist.

lithium AA batteries are recycled, a 2000 lb battery is significantly more payoff.

actually the research on why electric car batteries are not being recycled is because every car is too proprietary and it costs too much infrastructure to change for each battery manufacturer. Lithium has a lot of value so recyclers want to get into battery recycling but have made it known they need standardized battery design/packaging standards to make that possible.

Clearly you see the business plan!

actually adding 15,000 lb of battery to the truck reduces its efficiency significantly. Imagine loosing 15k of payload when you only had 60k to begin with, your new payload of 45k means you have to drive the route 4 times compared to 3 times for a diesel truck with our device.

Hopefully that makes sense.

integration with generators at the CO2 consumers site, cut out the shipping costs, that's an interesting thought experiment!

I'm surprised to hear this distinction. I've had my CDL for 15 years and worked on trucks for about a decade allover the east coast and found that when talking to the general public semi truck was the best way to talk about Class 8 trucks and calling them 'tractors' was always the worst.

Always interested to hear your experience.

I think the concern with capturing CO2 on this small scale is the network required to go pick it up. Still an interesting thought experiment and maybe that'll be a future market.

Hopefully we can convert home heating systems like yours to a biofuel soon to reduce the CO2 impact quickly.

Thanks for the idea!

Thanks so much! We appreciate all the words of encouragement

they do not. At least so far we have not had a regulatory hurdle that requires hazmat. Mostly because the CO2 is not flammable nor toxic (unless in a confined space, but hard to imagine a semi truck being in a confined space while our device is storing CO2).

the market for CO2 as a raw commodity is pretty large and growing significantly!

I think your comment on the concrete capped price assumes that the price for producing CO2 does not increase. If current concrete produces CO2 (which it does produce a lot) and CO2 gets taxed, it makes concrete that sequesters CO2 very financially viable even if it cost more than the current concrete market price. Plus I know I would pay more for concrete that sequesters CO2 so maybe that's another competitive advantage that allows it to cost slightly more.

Plants are great and we love and support using our lands more effectively, but there is not enough land to store the CO2 that has been emitted over the last century from fossil fuels, and keep up with the increasing energy demand from population growth as well as developing nations. So plants cannot do this on their own.

There is such a large market for CO2 (and its growing!) that we can find users of the CO2 very near our storage tanks. For example one pilot program we are planning right now has a CO2 concrete producer only 6 miles away! Of course our CO2 hauling trucks will have our device and we will get better and better at leveraging existing infrastructure (pipe lines and trains) to transport CO2 efficiently.

there are lots of uses for concentrated CO2. A few current uses include dry ice (shipping vaccines or other medical supplies), green houses, concrete, beverage carbonization, pumping it under ground into depleted oil wells for permanent storage, and refrigeration cycles.

There are also a lot of technologies in progress to use CO2, such as turning it right back into synthetic fuels!

The list goes on and seems to be growing by the day.

this is a very detailed and thoughtful question!

We have 2 or more chambers, we are balancing the number of chambers so that a chamber is always adsorbing while the other one (or 2) is transitioning temperature or holding a hot cycle to regenerate.

We adsorb at ambient temperature so cooling the previously heated device is not too much energy, mostly just a fan, but there is some available cool refrigerant from our dehumidifier/heat pump cycle that removes moisture from the exhaust to help quickly drop the chamber temperature.

We can use the exhaust waste heat to start heating the bed that is going into the hot regen cycle, then we use the waste heat from our exhaust dehumidifier to get the bed the rest of the way to the target hot cycle temperature.

Its hard to explain in text, but you can see that we get to use the hot and cold cycles from the refrigerant cycle to do work for us simultaneously and take advantage of the heat in the exhaust itself!

For sure we want to capture CO2 from all the combustion engines in use, starting with the largest emitters puts trains and cargo ships next on the list.

Lots of work to do to adapt our technology to those markets, but we love inventing new technologies!
