Well, one of the very interesting areas, and the bearer interesting areas for investment and the barriers also, is that the basic infrastructure that we have and take for granted on land does not exist in the open ocean. So the electrical grid doesn't exist. And almost every sensor almost every way of collecting data requires energy. Secondly, we don't have the communication issues, our did the communication structures, we don't have the cell towers, we don't have the ability to link into the internet easily. So when you're in the ocean, you have both the air water barrier interface. So if you are sending a message underwater, the you can't get up into the air to be picked up by the satellites, unless you have a device that is sitting right there at the barrier, a buoy, let's say that is picking up the underwater signal and retransmitting it up to the satellite. So all the things we take for granted, in building our networks, our Internet of Things on terrestrial soil, don't exist in the ocean. And we have to build them and get that sort of connectivity before we can have ubiquitous sensors throughout the ocean that can tell us what's going on. So some of the very interesting areas to invest in, are taking this terrestrial network and rolling it out into the coastal areas. You know, we see that there will be Unicorns of the ocean, very successful companies, which we call Gnar walls in the near shore area. So for example, the Internet of Things, stops, basically when you get to ports and marinas. Marinas are, in essence, parking garages for boats, but they have less sensors involved in them than your typical parking garage does. A typical parking garage knows when the slip or when the spot is occupied or not. And a typical Marina, it's a guy out there with a clipboard, jotting down, there's an open spot. They don't measure at the moment, the amount of energy that's used, the amount of water that's used, all the utilities that go to your boats generally don't get measured. One of the companies I've invested in called Falco coming out of France is a complete Internet of Things. sensor package for marinas. And so they are taking off by taking the IoT from the land into the first watery realm. Another company I've invested in is in essence providing electric vehicle charging stations so that you don't have range anxiety for your electric boat. And they're floating them off shore 10 miles, 20 miles. And so you can actually go out in your electric boat, far into the ocean and not worry about running out of power. Just simple land based technologies moving into the near ocean are where I see there's going to be huge growth opportunities. But there are still huge obstacles. Then, let's say 100 miles from shore, or 1000 miles from shore. How do you get the electricity out there? How do you get the communications out there? Those basic fundamental issues are real barriers to science and commerce.
